This is my 2nd house for solar panels. In an nutshell, all of the companies offer the same thing, near identical specifications, similar price per panel, and comparable warranties. So who should you choose?
I ended up going with the Certainteed system through Reginald George. He was a referral from some really picky friends of mine. I wanted to have a single point of contact, someone who is knowledgable in both solar and roofing, and gave me the information with no pressure for a sale.
My system was installed near seamlessly. They handled the engineering, permits, installation, etc. Reginald just took care of it. DONE! Best part is that my system is actually generating a more than anticipated, so our end of year true-up with PG&E is under $150.
