LG RESU Service in Oakhurst — Local Context
Oakhurst's 2,300-foot elevation improves solar panel efficiency — cooler temperatures mean panels produce closer to their rated output
Oakhurst is the largest community in the Madera County foothills, serving as the gateway to Yosemite National Park at an elevation of approximately 2,300 feet. Served by ZIP code 93644, Oakhurst is a hub for the surrounding foothill communities including Coarsegold, North Fork, Ahwahnee, and Bass Lake. The foothill location creates a unique solar environment: excellent south-facing roof exposure, cooler temperatures that improve panel efficiency compared to the valley floor, and high summer cooling costs that make solar savings significant. Summer temperatures in Oakhurst typically run 90–100°F — hot enough to drive substantial AC loads, but cooler than the valley, which actually benefits solar panel performance. PG&E bills for a typical Oakhurst home run $200–$400 during summer months.
Climate
Mediterranean/foothill. Summers 90–100°F. Cooler than valley. 270+ sunny days/year. Strong solar production.
Outage Risk
High. Frequent PSPS events during fire weather. Battery backup strongly recommended — often essential.
Electrical Infrastructure
Mixed. Many 1970s–1980s homes have older panels. Federal Pacific and Zinsco boxes not uncommon.
