sonnen Service in Del Rey — Local Context

Del Rey sits in the heart of the citrus belt — flat terrain, zero shading, and 285+ sunny days make it one of the most productive solar locations in Fresno County

Del Rey is a tight-knit agricultural community in central Fresno County, tucked between Fresno and Sanger along the citrus and grape growing corridor. Served by ZIP code 93616, Del Rey's residential neighborhoods are predominantly older single-family homes on flat valley terrain — the kind of unobstructed, south-facing rooftops that solar installers love. Summer temperatures in Del Rey regularly hit 100–107°F from June through September, and PG&E bills for a typical 1,600–2,200 sq ft home run $220–$380 during peak cooling months. The community's agricultural character means most homeowners are practical, long-term thinkers who understand the value of owning an asset outright — which is exactly how Robbins Energy approaches solar. No leases, no PPAs, no 20-year contracts. You own your system from day one. Del Rey's proximity to Sanger means Fresno County Building Department processes permits for this area, and Robbins Energy has navigated that process many times for homeowners in this corridor.

Climate

Hot semi-arid. Summers 100–107°F. Flat valley floor. 285+ sunny days/year. Tule fog possible December–February but minimal impact on annual production.

Outage Risk

Low-moderate. PSPS events rare in this valley corridor. Summer heat events occasionally stress the grid. Battery backup worth considering for households with medical equipment.

Electrical Infrastructure

Older stock. Many 1960s–1970s homes have 100A panels. Panel upgrades common before solar. Newer homes on outskirts more likely 200A-ready.
