When you compare your solar panel options from leading companies like SunPower, Canadian Solar, LG, Hyundai and SolarWorld, one of the biggest factors to consider is the solar panel warranties offered with their products. Solar panels come with two main warranties attached: the materials warranty, also known as the product warranty, and the production warranty.
Solar panel technology has been around in some form for a long time – Bell Labs invented the first useful solar cell more than 60 years ago, and scientists have known for centuries that the sun can be used to produce energy. However, it’s only in the last ten years or so that solar photovoltaics (PV) has really taken off as a renewable energy source. There are two major factors influencing the technology’s growth: the steady improvement of both solar panel cost and solar panel efficiency over time.
When it comes to solar panel manufacturers, there is no shortage of options for homeowners in 2019. Solar panel technology is improving every year, and many solar panel companies offer products that boast both high conversion efficiency numbers as well as impressive long-term warranties. SunPower is the leader with regard to efficiency across the board while LG solar panels are known for top tier design and aesthetic, but companies like SolarWorld and Canadian Solar offer much more appealing prices for their solar panels. How do the top PV manufacturers stack up? We’ll help you compare and contrast your options among the industry leaders – SunPower, Panasonic, Canadian Solar, SolarWorld, LG.
One of the things you may have questions about as you shop around for a solar system is where the solar panels are manufactured. This article will help you determine whether a panel’s country of manufacture should be a key consideration for you.

Does it matter where solar panel companies are based and where they make the panels?
When it comes to quality, the mention of any country’s name will evoke an association; each nation has its own brand image, which may or may not be justified. You as a smart solar shopper, however, will want to look at the facts in order to make a more well-informed decision. Our recommendation is to judge each panel by its own merits. (A good place to start is EnergySage’s Solar Buyer’s Guide.) Continue reading

In this week’s Solar News Roundup, SunPower’s premium solar panels are excluded from the Section 201 solar tariffs, and a new floating solar farm goes live in California.
Solar panels have a lifetime of about 30 years. With the increasing number of solar panels being sold and installed in the United States each year, it’s only a matter of time before high volumes of silicon solar panels are at the end of their useful life and have to be disposed of. Solar panel recycling is still at a very early stage, but as the market continues to grow, it will have an important part to play in the solar industry.
One of the most important decisions you make when installing solar is which company will provide and install your panels. There are a few large solar players who are always mentioned in conversations about solar panel companies and your options for installation.
