O'Neals is a foothill community in central Madera County, located near Bass Lake at approximately 1,800 feet elevation. Served by ZIP code 93645, O'Neals is a rural community with a mix of single-family homes and rural properties. The foothill location provides excellent solar exposure with cooler temperatures that improve panel efficiency. Summer temperatures typically run 90–100°F, and PG&E bills for a typical home run $180–$340 during summer months. PSPS outages are frequent during fire weather season.
For valley homeowners building a solar + battery system from scratch, EG4 paired with a Sol-Ark hybrid inverter delivers the best capacity-per-dollar in the Central Valley market.

In O'Neals, 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.
This area has elevated PSPS risk due to proximity to foothill transmission lines. Battery backup is strongly recommended, particularly for households with medical equipment, well pumps, or home offices. High. Frequent PSPS events. Battery backup strongly recommended.
EG4 batteries work with most 48V hybrid inverters including Sol-Ark 15K, Growatt SPH, SRNE HF series, and others. Robbins Energy typically pairs EG4 with Sol-Ark for the most capable and well-supported combination. We handle inverter selection, battery sizing, and the full installation.
EG4 batteries typically offer more kWh of storage per dollar than Tesla Powerwall. The trade-off is that EG4 requires a separate hybrid inverter (like Sol-Ark), while Powerwall 3 includes its own inverter. For homeowners who need maximum storage capacity on a budget — particularly in foothill and rural areas — EG4 is often the better value. Robbins Energy can provide quotes for both options.
