View detailsEvery project — a 6 kW residential array or a multi-MW commercial build — runs the same instrumented pipeline. Homeowners and businesses get the same transparency and the same real-time visibility.
We pull your interval usage history, read your roof from satellite imagery, and check panel capacity — before we ever visit.
A Wholly W-2 engineer walks the property, measures shading, scans the electrical panel, and documents structural details.
You receive a written proposal with equipment specs, system model, and a 3D layout — not a sales deck.
PG&E interconnection, city permits, fire marshal sign-off, and HOA handled under one accountable project manager.
Our in-house crew shows up on the agreed date. Daily progress photos in your inbox. Site protected, schedule in writing.
Every panel, battery, and meter streams to a private dashboard. We watch it continuously and dispatch a crew if output drops below spec.
EV charging for your guests and your fleet. Service robots for housekeeping supply runs and after-hours deliveries. Both designed, installed, and supported by the same in-house team.
Guest stalls, valet and fleet charging, DC fast for the forecourt, and load management across every unit.

“Simply the best in the Bay Area. Would rate Charlie and his team number one on quality and pricing.”
“Super customer service! Thanks again.”
“I don't normally write a review but Wholly Solar needs to be acknowledged for their spectacular work they completed on our roof. The team did a great job from start to finish. Charlie Answar helped us through the process by making sure solar installation was handled smoothly without interfering with our daily routine.”
“Superb! From the initial planning to the installation and switchover to solar power — everything was excellent. Charlie Anwer and his team explained all that would be required after taking measurements and reviewing my power needs. They were courteous, clear with planning and financing descriptions.”
“For any businesses in California who are paying 40,000 to 50,000 a year for your electricity — I highly recommend talking with Anwar from Wholly Solar. Wholly Solar installed a system that we now only pay $22.00 to $25.00 per month for our electricity.”
“Wholly handled our 11 kW solar + 2 Powerwall install from site survey through PG&E approval in eight weeks. Crew was on-site every day at 7am. Final bill matched the quote to the dollar.”
In-house crews across twelve counties. One call, one accountable contractor, one schedule.
Solar power is electricity derived from sunlight. Photovoltaic (PV) panels — typically silicon cells — convert sunlight into direct current, and an inverter converts that to alternating current for your home or business. It is a clean, renewable resource available throughout Northern California.
A solar system is an array of PV panels (modules) installed on a roof, parking structure, or ground mount. Sunlight striking the cells excites electrons, producing DC electricity. The inverter converts that to AC for your home or business. Excess generation can charge a battery or export to the grid under your utility tariff.
Solar batteries store excess generation for use at night, during peak TOU hours, and through PSPS events. They enable whole-home backup, time-of-use optimization against PG&E rate schedules, and grid independence for critical loads. We install Tesla Powerwall, Enphase IQ, and FranklinWH aPower.
Yes. Solar scales from 4 kW residential rooftops to multi-MW commercial arrays. We work on homes, agricultural sites, multi-unit properties, retail centers, warehouses, and light industrial. Engineering and permitting differ by site — our process handles all of it.
