How much does commercial solar cost in San Diego?
Commercial solar in San Diego typically runs between $2.50 and $3.50 per watt before incentives, putting most projects between $50,000 for smaller installations and well over $1M for large industrial systems. After applying the 30% Federal Investment Tax Credit, SGIP battery rebates, and MACRS accelerated depreciation, the net cost drops significantly. San Diego’s high SDG&E rates also mean faster payback periods than most other California markets, often landing between 4 and 7 years. SolarTech provides a detailed proposal with full financial modeling at no cost.
What is the ROI on commercial solar panels?
Most California commercial solar installations deliver an annual return on investment of 15% to 30% once incentives are factored in, with 25-year system ROI commonly exceeding 200%. The biggest drivers are your current utility rate, how much of your daytime load you can offset, and which incentives you qualify for. Under NEM 3.0, pairing solar with battery storage maximizes ROI by shifting stored energy to peak-rate hours and reducing demand charges. SolarTech models all of this year by year in your proposal so you see exactly what to expect before committing.
