What matters in San Diego
Key takeaways
- SDG&E is the key utility checkpoint.
- Obtain the City permit before installation.
- No installer claims were accepted without direct service-area evidence.
For San Diego, this guide uses 3 official utility, permitting, or licensing sources plus 2 installer-owned service-area sources; re-check each before contracting.
San Diego has strong residential solar demand, but SDG&E billing and address-level coastal/inland conditions should drive system and storage comparisons.
Climate and property considerations
San Diego's coastal and inland zones vary substantially; account for marine layer, roof orientation, wildfire exposure, and local shading.
Interconnection
SDG&E reviews distributed-energy interconnection and export billing; the City permit and utility application must both be completed.
Dated official sources
These primary sources are tied to the local claims above. Re-check them before signing because rules and program terms change.
