How to buy the best solar panels

Buying the best solar panels is very important, when you consider that these solar power panels will last as long as many mortgages do! As such, let us look at buying the solar panels that are best for your needs.

The recent advances of solar power technology have made solar panels the perfect solution to increasing energy costs as well as showing the negative environmental impact that fossil fuels have caused. By selecting the best solar panels for home use, your home can be both cost efficient and eco-friendly. This is because solar energy has no harmful gas emissions and therefore does not leave any carbon footprint. However, before you go out and start buying solar panels, you need to conduct a thorough research about the different aspects of solar power as well as consider the energy needs that your household will have. Another point to consider is you budget, along with proper assessment of your property, so that you will know where to place the panels to get the maximum exposure to the sun.

When you are looking to install a solar power system on your roof there are a few factors you should keep in mind regarding solar panels. Solar PV panel effectiveness largely depends on efficiency of the solar cells in the panel. Photovoltaic cells have reached an all time high of 40% efficiency on recent years for the most expensive panels. Efficiency is a measure of percentage of sunlight that is converted to usable electricity that can power household appliances.

Regular solar panel range from 13 to 25% efficiency with 15% efficient panels being that standard. When you are looking at solar panels to buy there are three main types of cells; polycrystalline, monocrystalline, and amorphous. Polycrystalline cells are the types of cells that are most common. These are generally lower in efficiency but operate better in overcast conditions. Monocrystalline cells are higher in efficiency but are also more expensive. Amorphous calls are generally the lowest grade and least efficient but most affordable.

Flexibility is a factor that many people dismiss, but it should be considered when purchasing a solar system. If you live in an area with constantly changing weather conditions, you will need flexible solar panels. In areas where there is sleet and rain you want to make sure the panels are flexible, so they can bear the changing temperatures from hot and cold. Changing weather causes rigid panels to warp and lower the efficiency of the entire array. This causes the panel to break. One broken cell can bring down the voltage of the entire array.

Solar panels are dropping in price every day. There will soon be a time when solar panels reach grid parity. Grid parity means that solar electricity will drop to the cost if utility grid electricity or less. This will happen even without government subsides as more and more foreign manufacturers drive up competitions between companies. There is also a growing demand among homeowners for solar which drives up supply.

What is the cost of a solar panel? To determine the cost various factors, have to be taken into consideration. Of course, the price is also greatly influencing by the kind of subsidies set in place for use of renewable energy by the government for the promotion of alternative energy sources. This is generally priced according to the following factors. It is based on how much capacity it generates (measured in watts), The physical size of each panel, the durability or warranty period offered, the quality of materials used in it, as well as the types of certifications that the panels have. The prices may also vary depending on how many panels are being purchased as part of the package. The general rule is that the price will decrease as the number of panels in the package increases.

A key factor to look at when purchasing solar panels is to purchase from a good and highly regarded service provider. This would generally ensure that all factors that add up give an efficient and high-performance product are taken care of. One of the main things to be sure of is that the temperature coefficient has low percentage per degree Celsius. Given that the conversion efficiency is a measure of how much solar energy a panel can convert into electricity, you should look for a panel with high conversion efficiency. A good solar panel will also have very little potential induces degradation.

Solar power is no longer the domain of the wealthy. There are inexpensive financing options and solar government incentives to help anyone who wants solar to get it. When shopping for a home solar system just like any product on the market, there are a lot of different brands and a range of systems just like any product on the market, there are lots of different brands and ranges of prices to consider. Always compare process and research the internet to ensure the quality of the product. Do not hesitate to ask around and see which brands are trusted to produce high quality products.
