I used solar-estimate.org before talking to any contractors and it completely changed how I approached the whole process. The design tool let me map out my roof, enter my monthly bill, and get realistic estimates from local providers. When I finally met with installers, I already knew what a fair price looked like. Saved me from getting ripped off by the first guy who quoted me $42,000 for a system I later got for $28,500. This site is genuinely useful.

Absolutely the best free resource I found when researching solar for my home. The online design tool is surprisingly accurate. I drew out my roof sections, added shading from a big oak tree on the south side, and it gave me a system size recommendation that matched almost exactly what two independent installers later suggested. The pricing database seems current too. Really glad I stumbled on this before signing anything.
As someone who spent weeks confused by solar jargon and conflicting salesperson pitches, this site was a breath of fresh air. The information service section explains everything in plain language — payback periods, net metering, federal tax credits, all of it. I printed out their cost breakdown page and brought it to every consultation I had. Contractors seemed almost surprised I knew what I was talking about. Hired a great company and the install went perfectly.
This website did exactly what it promises. I designed my home solar setup online in about twenty minutes, got a realistic price range for my area, and used that information to vet the three contractors I spoke with. One of them quoted me 35% above the estimate range and couldn't explain why. The other two were right in line. Ended up going with a local company and my system has been running great for eight months. Highly recommend starting here before talking to anyone.
