Sol-Ark 15K in Del Rey
The Sol-Ark 15K is a 15 kW all-in-one hybrid inverter that combines a solar charge controller, battery inverter, and grid-tie inverter in a single unit. It supports lithium and lead-acid batteries, works with most battery brands, and is popular for off-grid, grid-tied, and backup-critical applications in rural Central Valley communities.
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.
Clovis and northeast Fresno homeowners who want whole-home backup with flexible battery pairing find Sol-Ark 15K attractive — it works with EG4, Pytes, HomeGrid, and other batteries, so you're not locked into one manufacturer's ecosystem.
