Projects in San Diego can involve a wide mix of roof types, coastal and inland microclimates, older electrical equipment and varied household loads. The address and actual home matter more than the city name alone.
Start with the home
- Collect 12 months of electricity usage.
- Evaluate roof age, material, orientation and shade.
- Separate current loads from planned EV, HVAC or appliance electrification.
- Confirm who owns and controls the roof.
Model SDG&E billing
Ask proposals to identify the rate plan, expected onsite consumption and hourly export assumptions. A large annual-production number alone is not enough.
Compare complete project scopes
Use cash price, financed principal, equipment, production, roof/electrical work and post-installation service—not a monthly payment alone.
