Common questions from Mendota homeowners about solar installation, battery backup, electrical panel upgrades, and EV chargers.
Why is Mendota a strong solar market?
Mendota sits in western Fresno County where tule fog clears earlier than central Fresno, adding productive solar hours during the December–February period. Combined with 290+ sunny days per year, flat terrain with zero shading, and summer PG&E bills that regularly hit $280–$360, the economics are compelling. A properly sized system eliminates most of the summer bill on a cash purchase.
Do Mendota homes need panel upgrades before solar?
Most do. Mendota's housing stock is predominantly older — many homes were built in the 1950s–1970s with 100-amp electrical panels. We assess panel capacity during the free site visit and include upgrades in our scope when needed. The upgrade is handled as part of the solar project — no separate contractor, no extra coordination.
Is battery backup worth it in Mendota?
For households with well pumps, yes — battery backup is worth serious consideration. Mendota's rural western Fresno County location means occasional grid reliability issues, and a well pump that stops during an outage is a significant problem. A Franklin WH aPower or Enphase IQ Battery sized for essential loads keeps the pump and refrigerator running through most outages.
How does NEM 3.0 affect Mendota homeowners?
Under NEM 3.0, PG&E pays significantly lower rates for solar energy exported to the grid during the day. For Mendota homeowners, this means battery storage is increasingly valuable — you store your midday solar production and use it in the evening instead of selling it back at low rates. A solar + battery system under NEM 3.0 typically outperforms solar-only by 15–25% in annual savings.
