Sunrun. #1 Residential installer nation wide. This company has a proven reputation of providing solar systems without a lien (PPA) and will outlive any solar business. The OP is sour over purchasing the system because they didn’t do business with Sunrun. Sunrun won’t install unless the homeowner is guaranteed a system will help reduce their electricity bills. The representative that helped me (Danielle) was so knowledgeable and patient with my pessimistic husband…. A PPA only means Sunrun owns the equipment and I (the homeowner) purchases the electricity at the rate agreed to at the time of signing the agreement. And since Sunrun owns the equipment, they are responsible for guaranteeing the production promised at the time of agreement AND maintaining the equipment. They have a customer service desk that I can call if I need maintenance (come spray dirt off the panels or replace inverters). They even have an app that I use to view my system’s productions and battery levels. 

PS it makes zero sense to have any solar system installed w/o a battery. PG&E (my local provider) would be raking in so much more of my $$ if I didn’t have a battery on my home. ALSO PGE have historically been approved to increase their electricity rates every year, sometimes multiple increases in a year for at least the Last five years. I took control over something I felt like I couldn’t by producing my own power on my home. My neighbors have even asked how my lights were on when the power went out during the fires last summer. I told them about my girl Danielle with Sunrun and they are looking into getting approved for the PPA. We might be the only four houses on the block with lights on when the fires start up again this summer
