Solar Installation in Hume: What You Need to Know
Hume is a remote mountain community in eastern Fresno County, located near Kings Canyon National Park at approximately 5,200 feet elevation. Served by ZIP code 93628, Hume has a mix of full-time residences and vacation properties surrounded by Sierra Nevada forest. The high elevation delivers two solar advantages: cooler temperatures that keep panels closer to their rated output, and strong unobstructed sun exposure from spring through fall. PSPS outages are among the most frequent and prolonged in Fresno County — PG&E regularly shuts down the transmission lines serving this area for 48–72 hours or more during fire weather. For Hume homeowners, battery backup is not optional — it is essential infrastructure.
Climate
Mountain. Summers 78–90°F, winters 25–45°F with snow. 260+ sunny days/year. Cooler temperatures improve panel efficiency significantly compared to the valley floor.
PG&E Outage Risk
Very high. Hume experiences 4–8 PSPS events per year, with individual outages lasting 48–72 hours or more. Remote mountain location with limited grid redundancy. Battery backup is essential.
EV Adoption
Low. Most Hume households are full-time residents or seasonal vacation property owners with limited EV adoption.
Electrical Infrastructure
Remote mountain community. Many homes built in the 1970s–1980s with 100-amp panels that require upgrading before solar installation. Fresno County Building and Safety Division handles permits. Service calls require advance scheduling due to remote location.

Common questions from Hume homeowners about solar installation, battery backup, electrical panel upgrades, and EV chargers.
How often do PSPS outages hit Hume?
Hume experiences some of the most frequent and prolonged PSPS events in Fresno County — typically 4–8 per year during fire weather season, with individual outages lasting 48–72 hours or more. The community sits at approximately 5,200 feet near Kings Canyon National Park in a remote mountain location. Battery backup is essential.
What battery system is best for Hume?
For Hume's extended outage risk and remote location, we typically recommend a Sol-Ark hybrid system with expanded battery capacity, or two Tesla Powerwall 3 units (27 kWh total). The Sol-Ark hybrid can operate in off-grid mode — important for a location where grid outages can be prolonged.
Does solar work well at Hume's elevation?
Yes — very well. Hume's 5,200-foot elevation means significantly cooler temperatures that improve panel efficiency. Strong production from April through October, with lower output in winter months due to snow and shorter days.
What ZIP code does Hume solar serve?
We serve Hume ZIP code 93628, covering all of Hume and surrounding mountain communities in eastern Fresno County near Kings Canyon National Park.
Can solar work on a remote Hume property?
Yes. We install solar on remote mountain properties in Hume. For properties with limited grid reliability, we often recommend a Sol-Ark hybrid system that can operate in off-grid mode — providing complete energy independence during extended outages.
