Fresno is the largest city in the Central Valley and one of the most solar-productive locations in the entire state. With summer temperatures routinely exceeding 105°F and PG&E electricity rates among the highest in California, the financial case for solar in Fresno is straightforward: your air conditioner runs hard from May through September, your bills spike to $300–$500 per month, and a properly sized solar system eliminates most of that cost. Fresno homeowners across all 20 ZIP codes — from the older neighborhoods near downtown (93701, 93702, 93703) to the newer developments in northeast Fresno (93720, 93730) — are making the switch to solar at a rapid pace. The city's flat valley floor means most roofs have excellent south or west-facing exposure with minimal shading, and the 300+ annual sunny days ensure your system produces near its rated output year-round.
Available in 10–20 kWh configurations. Robbins Energy sizes based on your usage.
AC-coupled — works with any existing solar inverter.
Whole-home backup capable.
Compatible with 200A panels. Valley floor cities typically have flat terrain with excellent south-facing roof exposure. Most homes have unobstructed solar access. Older neighborhoods may have 100-amp panels requiring upgrade.
Permits issued by: City of Fresno Building Department. Standard battery storage permit and PG&E interconnection required. PG&E NEM 3.0 interconnection required. Robbins Energy handles the full interconnection application, which typically takes 4–8 weeks for approval after permit issuance.
Flat valley terrain means most rooftops have near-ideal solar orientation. Minimal shading from trees or neighboring structures in most neighborhoods. Mixed. Older central neighborhoods (93701–93706, 93728) often have 100A panels needing upgrade. Northeast Fresno (93720, 93730) largely 200A-ready.

Under PG&E NEM 3.0, battery storage is essential to maximize the value of your solar investment. Export rates are low; storing solar for evening use avoids buying power at peak rates (4–9 PM). In Fresno, summer electricity rates peak in the evening when solar production has stopped — battery storage lets you use your own solar power instead of buying from PG&E at peak rates.
Summer grid stress and occasional PSPS events affect this area. Battery backup provides peace of mind and maximizes NEM 3.0 solar value. Moderate. PSPS events rare in city core but summer grid stress can cause brief outages. Battery backup valuable for medical/home-office households.
