I've had solar for the almost 7 years since I moved into this house. The system was 3 years old when I moved in. When working it is awesome. Zero bills and $1k+ dividend checks per quarter. But the system now has had issues for almost 2.5 years and my output is only about 35% of what it was and still no fix and they are running more tests. It is the most frustrating experience ever. The main problem I see is the lack of companies to work on systems. They pop up and are gone within 2 years or so. The Sunpower umbrella is large as a parent company, but the companies that work for them stink, and you cant work with anyone else or it voids warranties. We need tons more companies that can deal with system issues. These issues with companies are on tons of forums. The companies install, then it is pretty much see ya if you have an issue. No one ever talks about that though. If I have issues with pretty much anything else power related, there are tons of companies to call. Solar, good luck, they are just as corrupt as anyone else!
