Why San Marcos Homeowners Are Going Solar
Inland North County summers push AC usage hard from June through September, and SDG&E's peak rates above 45¢/kWh make those months brutal. San Marcos also has a lot of newer construction with large, well-oriented roofs in communities like San Elijo Hills and Discovery Hills — ideal for solar. The result: homeowners here often see some of the strongest savings in the county.
How It Works in San Marcos
- Free consultation — we review your SDG&E bill and check your roof's age, pitch, and orientation.
- Custom design — a right-sized system (and battery, if it pencils out under NEM 3.0) built for your actual usage.
- $0-down install — the company owns the system; you pay a fixed per-kWh rate well below SDG&E, starting from month one.

NEM 3.0 and San Marcos Solar
Under NEM 3.0, exported solar earns far less than it used to, so the winning strategy is using more of your own power. With San Marcos's heavy evening AC demand, a battery that stores cheap midday solar for the 4-9pm peak is often what makes the numbers work. South- and west-facing roofs — common on the area's newer homes — are ideal. We'll model whether storage makes sense for your home during the consultation.
