I hired installers. I screened through 4 different ones. Ended up using SolarMe. I think they are based out of Ashbury Park. I have no complaints with them. They were great, only issue I had was there was something configured wrong during installation and took a little while to sort out. But it works fine now. They gave a great summary and estimate of the system. They also provide commercial grade panels (more durable, longer lasting, and cheaper than Tesla panels IMHO) and use an Enphase system which has good support. I would also ask for the critter guard to prevent squirrels and chipmunks under the panels. Overall, paid total $44,000 for panels and installation before the federal credit, which gave me $11,000 back. so, after federal taxes total was $33,000 for the largest size system I could get installed. Again, took me about 6 years of side work and consulting to save up for it. But it's something I really wanted to do.
