Residential Solar Panel Systems


Decision to buy a residential solar panel system is quite a big verdict and hunch. Making certain that the unmarred photovoltaic (PV) system is the precise unit for the estate is an inevitability. Due to several kinds of choices feasible nowadays, the anticipating buyer has many points to debate over before catching the venture. Securing a non-constraint attest will be giving a casual cost for an absolute unit designed for the residence. But drawing an attest for $10,000 and another quote for $20,000 flags a lot of scope for knowing the soundness of various solar power systems, and the hypothesis behind the large difference in prices.

Aforetime devising a full PV system convenient for a equity, one should be clear and confident and investigate that it is also hypothetical to have corresponding unit on the equity. City guidelines, homeowners associations, and a few other aspects can dispense to an owner detecting that it should be a no go on instating any kind of unit on the equity. Reviewing the standards, contacting relevant work stations, and auditing the measures regarding a residential solar panel system before commencing. There’s nothing as disappointing as spending several hours of scrutiny and arrangement only to unearth that it is impossible to integrate the installation as expected to one’s position.

There is an another forethought that is concerned with the load of watts an equity needs to fortuitously power the full household. The arithmetic is the load of the amount of everyday watts consumed by the household branched by the amount of optimal sunlight originated according to the equity location and seasonal time of the year. Once the load and energy essential is revealed, the buyer can judge whether to buy full inclusion or  a partial one to get the project commenced. Sometimes, an equity possessor may only buy a 50-watt residential solar panel at a time reducing the elementary expenditure.


The kind of system integrated would be up to the buyer, too. There are several kinds and traits of units granting a full custom tailored practice. Not all the systems are reared coequal. An eminent quality unit will last for over 20-30 years with minimal conservation, while a low quality unit will last about 9-10 years requiring redundant preservation. Sure the cost might be lesser on those low quality units, but at today’s cost there is no logic to resolve for another finest.


Many equity owners acknowledge the price of installation for residential solar kits. Unfortunately, many people guess that this is a best time to get into the do-it-yourself projects. Without appropriate experience, the full project from the early stage to the finish can take incomparably longer, bereft warranties, and cause undue failure. Giving job to a professional installer is the only path to guarantee a flawless residential solar panel system installation. A professional assures that the project is cost effective, authentic, and gets finished in a sum of days and not weeks or months.


There are several deliberations that come into the play with an installation of a residential solar panel system. Many things can alter and bring a change or disturb the installation whether it is a HOA protocol, huge ripened trees, or the size of the roof. Approaching a professional installer or a dealer is the firstmark in taking the inconvenience out of insuring a proper installation of an exemplary unit. In extension, hiring a professional makes sure that the install will take only a few days compared to a few months.

Solar Panels: Composition & Function

Solar Pannels

Due to the recent growth in popularity and affordability, more people are seeking information on solar panels.  The interest in information on solar panels ranges from their composition and construction to the way they function.  Solar panels consist of a conglomeration of photovoltaic cells.  The photons in sunlight are absorbed by these cells and the displaced electrons are caught in a magnetic field that converts them into Direct Current energy.  DC energy can then be transformed into the Alternating Current energy that most household appliances run on.  This is done by the use of a power inverter.

The materials that have been found to be the best at absorbing photons from the sun are cadmium telluride, copper indium gallium selenide/sulfide, and various types of silicon.  Some of the most common silicon based compounds used are monocrystalline, polycrystalline, and amorphous.  These various substances go into creating the panels.  They are capable of the same work but have minor differences.  Those differences are in the price, in the slight difference on how effective they are, and will also depend on the installation location (a ground setup versus a rooftop system).

Since there are limits on the amount of power a single set of connected cells can convert into usable energy, the most effective use of solar energy is realized when multiple photovoltaic modules are installed.  Besides building integrated photovoltaics (small modules that look like regular roofing tiles) and solar thermal setups (for producing hot water in the home) there are three main types of panels available.

Information on solar panels, classified as thin film, shows that they are created from amorphous silicon, cadmium telluride, and copper indium gallium selenide/sulfide.  While these are currently the least expensive types of modules available, they are less suited for residential rooftop installation.  Thin film modules are most commonly used for ground power systems on large plots of land.

Polycrystalline silicon (also known as multicrystalline, ribbon or multi-silicon) are a step up from the thin film.  This composition allows for placement on rooftops while exhibiting improved ability to capture and convert photons.  Information on these solar panels shows that the element that makes them slightly less efficient than monocrystalline silicon modules is the same thing that makes them more affordable.  The construction of their design minimizes the gap in efficiency of energy production as long as multiple modules are installed.  Visually they are easy to recognize.  They are composed of thin conduit wires arranged in narrow rectangles with the silicon woven through the wires.

Rooftop systems constructed of monocrystalline silicon are some of the most popular.  Although these modules are more expensive, due to their high silicon content, they are also considered the most effective.  Since monocrystalline silicon is so efficient at absorbing photons, using a set up with that material requires fewer units for solar power generation.  These are easily identified by the square shaped cells set up in a grid across the surface of the modules.  Although the mono and polycrystalline silicon units cost more than the thin film, they are a solid investment.  Over a period of several years, they will pay for themselves.

Other useful information on solar panels includes the fact that they will greatly impact a home or small business’ utility bills.  They have a life span that will go on for many decades and they are an extremely eco-friendly method of power production.

How Solar Panel Technology Generates Electricity

How Solar Panel Technology Generates Electricity

A solar panel is a delicate piece of technology that is rather complex in structure and composition. With the rise in interest of sun power for homeowners and small businesses, many people are wondering what goes into these modern marvels.

Power cells have two purposes. They have to intake light energy from the sun and convert it into a usable electrical current. They also have to effectively funnel this current into battery storage. There are multiple power cell designs on the market now that accomplish these two functions.

No matter the design, each solar panel is built around silicon disks. The silicon in the cell is cultured from crystals into tubes and then cut into thin layers. Substances called dopants are added to the wafers in trace amounts to give them their electrical properties.  Examples of common dopants are boron, arsenic, antimony and phosphorous. These dopants will replace tiny parts of the silicon’s crystal lattice, effectively becoming part of the crystal itself. Occasionally, the dopants will be added as a film across the silicon.

Many power cells are also coated with a substance that increases the cell’s ability to take in energy. An increase in the rate of speed is also helped by this substance. All power cells come with a protective layer of very fine glass that protects the cell from disagreeable weather while permitting the transmission of light.

Multiple cells (sometimes dozens of them) make up a single solar panel. The process of taking in sunlight, absorbing it, and converting it into electrical energy creates a great amount of heat. Less than 25 percent of the energy from the sun is actually processed into electricity, or solar electricity. The rest washes off as dispersal heat. To keep this heat from warping the cell, it is bonded to pieces of thermal concrete that work to direct heat away from the cell.

There are many ways to design a solar panel. There are the monocrystalline silicone cells, polycrystalline silicon cells, amorphous silicon (or film) cells, integrated photovoltaics and thermal cells.

Monocrystalline silicon cells are the best in terms of efficiency. Compared to other power cells, these turn a greater portion of sunlight into energy.  These cells are pricier, but the price can be justified because the output of more energy per square foot makes them the go to solution for residential roofing. The cells in monocrystalline silicon are square shaped.

Polycrystalline silicon cells are infused with lower amounts of silicon than monocrystalline cells. The lower amount of silicon means they are less efficient, but they are also less expensive to produce. The cells are often constructed to offset this lessened efficiency. They usually have the same footprint as a monocrystalline cell while possibly being a bit bulkier.

Amorphous cells (film) are very inexpensive to produce and can handle large amounts of heat. These cells are not typically employed for residential projects.  They are more likely to see action on power farms.

Integrated photovoltaics are designed to look like roofing tiles that can be integrated into a building’s look. This design comes with a higher price tag and is usually reserved for larger structures.

A thermal (hot water) solar panel is not used for electricity generation.  They are instead ideal for heating water for homes or pool usage.

Financial Benefits of Solar Panels

Financial Benefits of Solar Panels

While brainstorming home improvement projects, consideration should be given to the addition of solar panels.  Not only do they offer a positive impact on the environment, there are financial benefits both now and in the future, as well as gaining independence from utility companies while maintaining reliability. With companies readily available to install panels and the affordability in which they have recently gained, it is a wise economical decision all property owners should explore.

We live on a solar fueled planet, so investing in this commodity makes financial sense.  Living green is a topic at many dinner tables these days, with topics ranging from composting to recycling. With the tools to utilize the sun’s energy becoming so affordable, most homeowners or business owners are within reach of obtaining their own solar panels.  The investment is just that, an investment, not a second mortgage.

Though the price of gasoline, food and insurance continues to rise, just the opposite is happening in the renewable energy market.  Solar prices have come down significantly over the past few years, making panels much more affordable for the middle class.  When comparing the current rate for product and installation versus the next few years of utility bills, the savings are unparalleled.  It is definitely worth taking a look at this option.

There is an unlimited amount of natural resources available in the sun. There is no government control over the usage of sun power.   With the use of the best solar panels, that resource can be used for an indefinite amount of time. When professionally installed by a trained technician, maximum exposure can be guaranteed. All that is required is enough roof space for the panels as well as exposure to the southern skies and any business or resident can invest in the installation. The installation time is short and non-evasive.  Once installed, they are out of sight and out of mind, until that first utility bill shows a zero balance, or possibly even a credit.  There is even the possibility of giving back to the community by returning power to the local grid. Some states will pay customers to return excess power, which can then add to the investment value of the system.

As for gaining energy independence, if an unexpected event causes damage to a power company’s transformer, numerous customers in the area experience power outages that can last minutes to days on end until the necessary repairs are completed. Producing one’s own energy source offers independence from larger utility companies who also control pricing and potential usage.  As the economy continues to suffer, prices continue to rise.  The competition is often nonexistent, so switching companies to get a better deal is not always feasible.  Businesses and residents are also subject to uncontrolled rolling black outs due to the economic hardship the utility companies are suffering from.  Installing Solar panels removes homeowners and business owners from the grid, therefore avoiding any outages completely as they are relying on the system that harnesses the unending energy flow from the sun.

There is a better solution within reach to be more ecologically friendly, free from the restraints of power companies and still maintain the reliability everyone has come to expect.  Solar panels are a home improvement project well worth looking into for both homeowners and business owners. These systems have been around since 1954, producing cleaner energy using natural resources.  A qualified technician is only a phone call away to get started.

Know What Types Of Solar Panels Are Best For You

Types Of Solar Panels

When it comes to making the right choice for powering a home or small business efficiently, it is important to know what types of popular solar panels exist on the market and the benefits of each one. This is a big choice to make, and the initial cost can vary depending on what option the purchaser selects, so a good amount of knowledge is important.

One of the most popular designs is known as monocrystalline silicon. These are the frames that people are used to seeing, and are currently the most efficient kind available. This means that more energy is converted out of the available sunlight. If a consumer is thinking about switching over and considering these due to lack of sunlight available, they should not worry. Studies show that any kind can be installed as far north as upper Canada and still be energy efficient. When considering maximum efficiency, these types of solar panels are one of many great options.

Polycrystalline silicon is the next worth mentioning. They have lower silicon content than monocrystalline silicon frames, but they can be more cost efficient when it comes to the initial purchase price. The construction and design of these frames can make for slightly lower efficiency, but would be a great option for roof top installation.

Another of the popular types of solar panels is BIPV, or building integrated photovoltaic. These frames can be made to look like roofing tiles or shingles, which is an option for the consumer who wants to use alternative energy, but does not want their house covered in traditional panels. In general, these are not quite as efficient as the silicon brands, but in instances where appearance matters, they are a good option. These shingle-shaped designs are weather resistant, which means they are able to withstand heat, rain, snow, and hail.

The last and maybe most specific option on the market are hot water or thermal frames. These are targeted at hot water heating, which cuts down monthly costs when heating the water for the home, pool, or hot tub. This can be an especially attractive option for someone with a large pool that requires heating year-round or for many months out of the year.

Since these and other types of solar panels have not been out on the market for very long, and using alternative energy is still a fairly new concept, people may be wondering how long these systems will last. The frames are built to withstand inclement weather, and can be inexpensive to have installed and maintained by the best solar installers. The typical lifespan can exceed twenty years as well. They can pay for themselves in just a matter of years. Where cost is a consideration, it may not be necessary to install more than what is initially considered.

One important factor to consider is how important any types of solar panels can be for helping the environment and the individual’s electricity bill. It is also important to know how easy it is for anyone to make the right choice with some research. This technology is rising in popularity, and will be around for a long time.

What Would Be Required For Solar Power To Become A Mainstream Energy Source?

What Would Be Required For Solar Power To Become A Mainstream Energy Source

How could solar power surpass fossil fuels in terms of electric grid percentage? Solar power has one important limitation – It can’t produce electric power on demand, like other energy sources such as hydroelectric power or fossil fuels. Instead, solar power produces its energy when sunlight is available. This is no problem for large utility-scale projects, since they export all of their output to the electric grid. From the point of view of the homeowner, on the other hand, solar power production rarely matches demand – the productive hours of a solar PV system are normally when complete families are away due to work and academic activities. Of course, small PV systems can also export electric power to the grid and purchase energy during peak hours, but the energy they actually use doesn’t come from solar power – the production of their system was likely consumed by commercial or industrial buildings during the day. In order for solar power to become a mainstream energy source, the right incentives must be in place and some emerging technologies must be adopted and developed further.

Emerging Technology: The benefits of technology can be artificially improved by electric utilities, local governments and the federal government. There are many types of incentives available for solar power such as rebates, tax credits and tax exemptions. For large scale producers of electric power, there are carbon taxes to penalize fossil fuels and carbon credits to incentive green power providers. It is important, however, for these incentives to be available continuously, regardless of government changes.

In order to use solar power at the utility scale when sunlight isn’t available, an autonomous energy storage solution is required. Traditional battery banks can accomplish the task for individual homes or stand-alone PV systems, but they are expensive and potentially dangerous. Besides, when managing thousands of homes with solar PV systems equipped with storage technology, automation and networking capabilities are required. In other words, the system must be a smart grid. The Clean Power Plan as announced by President Obama is an important step in this direction. It’s main goal is reducing emissions by 32% of 2005 levels, by the year 2030. Nation-wide standards will be published and the states that take action sooner will be rewarded.

Renewable Energy Will Beat Fossil Fuels

Renewable Energy Will Beat Fossil Fuels

According to predictions by Bloomberg New Energy Finance, renewable energy projects will represent two-thirds of all energy investments between the years 2016 and 2040. That’s right, solar power and other renewables will eventually surpass coal and gas combined! This is excellent news for our planet’s ecosystems, and also great news for us as electricity consumers: some of the newest wind and solar farms coming online are reaching record low prices, and have become capable of competing head-on with established fossil fuels such as coal, but without the negative environmental impact.

Breaking Down the Numbers: Bloomberg New Energy Finance predicts that renewable energy investments from 2016 to 2040 will add up the impressive amount of 7.8 trillion dollars. Just for comparison, coal is expected to draw 1.2 trillion dollars over the same time period, not even one-sixth of the expected investment for renewables. The outlook for gas is even less promising, as it will only add up around $892 billion in investments through the year 2040. The predicted 7.8 trillion dollars in clean energy investments are split mostly among solar power ($3.4 trillion), wind power ($3.1 trillion) and hydroelectricity ($911 billion). Solar power is once again proving its feasibility as a mainstream energy source, ahead of other renewable sources, not to mention fossil fuels. Most of the new coal power plants are expected to be built in developing regions in Asia, particularly India and China, the two most populous countries in the world. On the other hand, gas will remain an important energy source for several decades in the USA. Nevertheless, at the global scale renewables will eventually surpass both coal and gas. Gas will fall behind renewable sources in the energy race by the year 2027. Coal, currently at the top of the list in terms of installed capacity, will be overtaken by renewables around the year 2037.

How Renewable Energy Will Behave by Region – Europe as a whole is expected to take the lead in clean energy adoption, with a power grid that will be 70% renewable by the year 2040. This should come as no surprise, since Ernst & Young has placed several European nations among the top 20 best countries to invest in renewable energy:

Germany – 5th place

France – 8th place

United Kingdom – 13th place

Denmark – 15th place

Netherlands – 17th place

Turkey – 19th place

Belgium – 20th place

North America is also expected to see a lot of activity in the renewable energy industry. For example, United States is expected to increase its share of clean power from 14% to 44% by the year 2040, and the country currently holds the 1st place in the Ernst & Young ranking. Canada and Mexico are not falling behind either, securing the 9th and 7th places, respectively. Mexico in particular is an example of how favorable policies can boost the adoption of renewable sources: the country recently opened up its energy sector, previously a state-owned monopoly, and it already has over 2000 megawatts of private contracts in the pipeline,distributed among solar and wind farms. Speaking of Mexico, Latin America in general is expected to see a lot of activity in the energy industry. For example, Chile and Peru share the Atacama Desert, possibly the best place for solar power in the world, receiving around 2700 peak hours of sunshine every year.

Argentina has also carried out reforms that favor renewable, and the country will now be able to benefit from its considerable wind power potential; some estimates indicate that the wind power potential of Argentina is able to cover the full energy demand of Latin America! Although China and India are expected to continue depending on coal in the long term, it doesn’t mean that these countries will not see activity in the renewable energy sector. In fact, the opposite is true: consider that these two countries have the largest populations in the world, and that translates into a considerable appetite for energy. In the Ernst & Young ranking, China sits in the 2nd place, just below the USA, and India is number three.

Even Automakers Like General Motors Are Going Solar

solar car

The automotive industry is shifting to green power, and not just the cars themselves, but also the facilities used to produce them. Cars are becoming hybrid and electric, and solar power is the most promising renewable energy source to power them, given that it is found everywhere and is becoming more affordable year by year. However, automakers themselves are also implementing solar power in their manufacturing facilities, even if such facilities are used to manufacture gas cars. General Motors is a leading company in the adoption of solar power, and will soon make the production of its Chevy Corvette greener.

Earlier in December 2015, General Motors announced it would soon start installing an 850-kilowatt solar array on its Corvette manufacturing plant in Kentucky. The array is estimated to produce 1.2 million kilowatt-hours per year, which is enough energy for the manufacturing process of 850 Corvettes. Being an iconic vehicle, the Corvette will continue to be sold in the long term, even as we approach the age of electric vehicles. According to GM, the Corvette is the most efficient sports car in the market, with a highway rating of 29 mpg.

Solar Car Design

This project is part of a broader program by GM to become greener, as the company has set forth the ambitious goal of cutting down its carbon footprint by 20 percent, by the year 2020. As of now, GM is the number one automaker in the USA in terms of solar power adoption: they are soon expected to reach an installed solar power capacity of 11.4 megawatts in US-based facilities alone, and a global capacity of 48 megawatts.

According to the recently released report by the Solar Energy Industries Association (SEIA), its Solar Means Business report, where it ranked US companies in general according to their adoption of solar power: GM was #21, closely followed by Toyota at #25. GM is also committed to reducing the carbon footprint of the vehicles it manufactures, and has established the following goals for the year 2017:

  1. Having 500,000 vehicles on the road using electricity, including hybrid and fully electric models. This will reduce the carbon footprint of their vehicles, while stimulating the solar power market.
  2. Doubling the number of car models in the USA which are capable of achieving a fuel efficiency above 40 mpg.

General Motors is participating in the transition to a green power grid as well. as The company is one of the founding buyers in the Business Renewables Center, an initiative by the Rocky Mountain Institute (RMI) which has the goal of adding 60 gigawatts of solar and wind power capacity to the US grid by the year 2025. It seems President’s Clean Power Plan is having a positive response among corporations, even those not commonly considered “green” such as automakers.

You can also benefit from solar power while also making your home or business greener. Talk to our experts today to learn more about the technology and also to contact the best solar power providers and installers in your location.

Why is Solar Power Becoming Cheaper Throughout the World?


A pair of decades ago, solar photovoltaic panels, commonly known as PV panels, were an experimental technology, with extremely high costs and hardly any business potential. But now, on the other hand, we’re getting to see solar power plants reaching energy costs under 6 cents per kilowatt-hour, in many cases before accounting for subsidies and incentives. There are many reasons that have contributed to turning photovoltaic technology into a competitive energy source.

The Technology Itself Got Cheaper – Solar modules now cost less than a dollar per watt of capacity. Of course, a functioning solar power plant costs more than that because complementary equipment is needed, and on top of that it is necessary to cover the construction cost and the financing cost. However, photovoltaic modules themselves are now cheaper than ever before.

Funding Sources Now Trust Solar Power – Banks can be very picky when it comes to funding. For example, you can’t expect to get a low interest loan if you haven’t established a credit record. The same can be said of businesses: banks and investors will offer the best terms if they trust the business. When solar power hadn’t proven its capacity to yield profits, nobody was going to lend low-interest capital to developers betting on the technology. Therefore, the higher interest had to be diluted into the cost of energy. Now that solar power is an established industry, capital for it is more abundant and interest rates have dropped.

Economies of Scale Have Made Projects Cheaper – A solar farm with multiple megawatts of capacity is much more expensive than your average residential PV system. However, the cost of one kilowatt is considerably lower for solar farms. While the price of solar modules doesn’t change that much, there are other system components that become much cheaper to install at larger scales, such as inverters and racking. Solar power is becoming more affordable for the simple reason that solar farms are getting larger.

The Four Ingredients for Solar Power to Be Successful

Ever asked yourself why solar power is a thriving business in some locations, but is barely used in others? In principle, solar power is simple: photovoltaic panels are installed and wired, their DC output is converted to AC, and now they can synchronize with the power grid to provide energy. However, external factors may prevent a technology that works perfectly from being financially attractive. With solar power, four key ingredients must be in place.

Ingredients for Solar Power to Be Successful

1) An Abundant Solar Resource – If a project location does not get enough sunlight, you can install the most efficient solar panels in the market but will not make much energy from them. Any obstacle that blocks off sunlight diminishes the output of a solar array, and some examples are:

  • Hills or mountains
  • Trees
  • Buildings
  • Unipole billboards

The list goes on, but the basic rule is that anything capable of casting a shadow on top of a solar array is counterproductive. Geographic location can also have a negative impact on solar power. Days become shorter during the winter as you move far to the north or south, diminishing the energy output of a solar array. Solar energy production may become very low during the shortest days of the winter, precisely when the most energy is required for heating.

2) Affordable Technology – Residential PV systems are now priced at around three dollars per watt, while utility-scale projects are approaching one dollar per watt. For comparison, a solar PV system used to cost more than $10/watt in the year 2000. The gradual reduction in technology costs has been a key factor driving the solar industry. However, there may also be artificial factors influencing the installed cost of solar power:

  • An installed solar array will be more expensive in countries with higher wages.
  • Taxes can make or break a solar power project; high taxes may make the project unfeasible, while tax exemptions and credits may drastically reduce its payback period and make it more attractive.
  • Utilities trying to meet renewable energy targets may offer rebates, further reducing the cost of an installed and functioning solar photovoltaic system.

Sometimes, the Levelized Cost of Energy (LCOE) is a more useful metric than the upfront cost of solar power, since it provides a direct way to compare it against local utility rates. Assume a solar PV system offers an energy cost of $0.12/kWh: it saves money if local electric rates exceed that value, but offers no economic benefit if the rates are lower.

3) Low-Cost Capital – A residential PV system is a sizable investment, not to mention a utility-scale solar farm. For example, even if the $1/watt mark is reached, a 100MW solar farm will cost 100 million dollars, and few project developers will be willing to pay that kind of cash up front. Therefore, it is common for solar PV systems to be installed with loans, but the interest on a loan can determine whether the project is lucrative or not. Assume a solar PV system has a rate of return of 10 percent: any loan with an interest rate below that value is attractive for financing the project, but any loan above that rate actually means the developer loses money. Corporations have access to very favorable loan terms, and individuals with a great credit record may also apply. However, a solar PV system is not something you can buy with your credit card! The cost of capital does not affect the installed cost of a solar PV system, but it influences the LCOE: higher interest rates translate into a higher LCOE and less likelihood that the solar PV system in question will be able to compete with electric utility rates.

4) Favorable Regulations – For the solar industry, governments can be the best ally or the worst enemy.

  • Solar power can thrive in a country with a strong renewable energy portfolio, an electric sector that is open to private investment, and with tax incentives for renewable energy.
  • On the other hand, the industry is doomed to fail in a country where the electric sector is operated exclusively by the government and homes are not allowed to have net metering for solar power.

Argentina and Mexico are two clear examples of this, both countries recently opened up their electric sector to private investments, and renewable energy sources like solar and wind power have grown considerably in just a few months.

You can visualize the solar industry as a four-legged table. If any of the legs are cut, solar power ceases to be a solid investment. However, solar power is a lucrative business when there is an abundant solar resource, affordable technology, low-interest loans and favorable regulations.
