The sun is a powerful source of energy, and many countries have taken the initiative to capture and use it as a viable source of electricity. According to the International Energy Agency (IEA), the five countries that produce the most solar energy are Japan, China, the European Union (EU), the United States, and Vietnam. China has seen a dramatic increase in solar energy production due to its desperate need for electricity and its severe air pollution crisis. The Chinese government is aggressively encouraging financial institutions to provide incentives for solar installations.
The EU is an economic and political union of 27 countries and is ranked as the second largest producer of solar energy. The number of European Member States holding solar energy auctions has increased, helping to lower prices. The United States has continued to improve its position as a leader in solar energy by expanding its facilities in the utility sector and the residential market. This growth is largely due to significant government incentives given to the residential sector, which is a fast-growing market segment.
The IEA estimates that solar energy production represents 860 million tons of CO2 savings each year. A gigawatt (GW) is a unit of measure of electrical energy. Photovoltaic (PV) technology is made up of photovoltaic materials and devices to convert sunlight into electrical energy. A single photovoltaic device is known as a cell and a single photovoltaic cell can produce approximately 1 or 2 watts of power.
Kyocera TCL Solar recently completed a 29.2MW solar power plant on reused land in Japan. Palmetto Solar has a strong solar equipment offering and is trying something different from most solar companies when it comes to customer service. Palmetto offers proactive monitoring and tiered support levels in a subscription model called Palmetto Protect. While some of the higher levels may only pay off in the most extreme cases of failure, solar customers who are uncomfortable with their equipment can buy a little peace of mind for a small fee.
Solar panels are often low-maintenance systems, and people can monitor their systems through the apps available on most installers, including Palmetto. Palmetto also receives an A+ from the Better Business Bureau, which companies pay to receive a rating. Competition in any industry is great, but it can also be too good. With so many options to choose from, how can a homeowner decide which solar panel is best for their home? To produce this lineup, I have drawn on a number of different resources.
I consulted a panel of solar industry experts, relied on official government data sources, and collected thousands of consumer review scores on our website. The most important thing is that I researched what you, the consumer, want from your solar panels. But if you want to go deeper, take a look at all the other rankings on this page. They will tell you which panels are the most efficient, which are best for those who buy on a budget, and which brands are manufactured here in the U. S.
I asked an in-house group of experts in the solar industry to weigh the pros and cons of different brands of solar panels and choose which ones they would install in their own homes. Premium solar panels are high quality panels and feature top-of-the-line specifications, along with a higher price. The best options from our experts in the premium solar panel category are Panasonic, LG and SunPower. All three companies manufacture high-performance modules with superior workmanship, higher efficiency ratings, better temperature coefficients, lower degradation rates, and market-leading 25-year product warranties. Panasonic and LG solar panels are the best options from our experts according to experts because they are produced by large conglomerates known for their high manufacturing standards and will almost certainly be available to meet any warranty claims in the future. Comparing Panasonic and LG panels, experts say that Panasonic has a slight advantage in terms of specifications while LG has a small cost advantage. SunPower's ranking suffers due to its problematic financial position along with its very high price. Canadian Solar and Trina Solar offer high quality panels with specifications not far removed from premium solar panels but at substantially cheaper prices than premium models - often saving homeowners hundreds or even thousands of dollars in upfront costs. The only major drawback of Canadian Solar and Trina Solar is their warranties; both offer 12-year product warranties while this is better than the 10-year industry standard it is still shorter than those offered by premium brands.
