SAN RAMON — All solar panels come with a 25-year manufacturer’s warranty, but the big question is whether the manufacturer will still be around in 25 years to honor its warranty. During the last couple of decades, the solar industry has seen manufacturers come and go, and new ones are sprouting up all the time. That’s why it’s important to carefully consider the company you purchase your solar equipment from.
Your safest bet is to buy solar equipment from a well-established company. In most cases, this will be a company whose name you recognize. For example, SunPower has been around for a long time and is well-known for its quality and reliability. The same can’t be said of the many smaller, newer manufacturers that have popped up during the last decade.
Another attribute to consider in a solar manufacturer is diversification. In addition to being well-established, manufacturers like Panasonic, Mitsubishi and LG are diversified, global companies that produce many other products besides solar panels. Because of this, even if one of these companies decides to stop making solar panels, it won’t kill their business, which means they’ll still be around to honor their past warranties. Companies that solely manufacture solar panels don’t have this kind of diversified stability.
Given the competitive and volatile nature of the solar manufacturing industry, it’s just not a good idea to entrust your money to a relatively new, non-diversified company. Instead, put your confidence in an established company that’s likely to be around in 25 years.
