Welcome to California Home Solar Discussion

What you'll find here

• Real case studies from the Bay Area, Sacramento, Central Valley, and San Diego
• Side-by-side comparisons of the best solar panels in california builds for each climate zone
• Step-by-step permit walkthroughs for different AHJs across California counties

Common questions we cover

How do I size a system for my specific tilt and roof orientation? What happened to NEM 3.0 and is it still worth going solar without batteries? Which Tier 1 panel manufacturers are actually bankable in 2026? Should I buy panels directly online or through a local installer? How do I verify a quote isn't inflating the per-watt cost?

Jump in, introduce yourself, and post your system specs or questions.
