Residential systems in California are sized under NEM 3.0 and typically capped near 10 kW (~2,500 sqft of array). We design within Title 24 and your utility's interconnection rules.
How does the CA rebate work?+
Estimates include the 30% Federal ITC. Additional programs like SGIP for battery storage and local utility incentives are applied during your final quote.
