We Will Make The Sun Shine For You
Wholly Construction is a California General B contractor (CSLB #1024858) delivering six integrated trades — solar, battery, roofing, renovation, EV charging, and service robotics — to homes and businesses across Northern California. One accountable contractor. In-house W-2 crews. Free site survey. Made in the USA.
Solar, battery, roofing, renovation, EV charging, robotics. We design, permit, and install across every system that makes a California property work — without subcontractor handoffs.
Custom-engineered residential & commercial arrays, 4 kW to multi-MW.
Whole-home battery storage for PSPS events, TOU optimization, and grid independence.
Solar-ready roofing engineered to outlast the panels it supports.
Whole-home transformation by people who care.
Level 2 & DC fast charging powered by your own roof.
Service robots engineered for hospitality, healthcare, and food service.
Every Wholly project runs on the same instrumented pipeline — whether it's a 6 kW residential array or a 2 MW commercial build. Homeowners and businesses get the same transparency, the same engineering rigor, and the same real-time visibility into their system's performance.
15-minute call. We pull your last 12 months of utility usage, satellite-image your roof, and check your panel capacity — before we ever visit.
A Wholly W-2 engineer (not a subcontractor) walks the property, measures shading hourly, scans the electrical panel, and documents structural details.
You receive a written proposal with equipment specs, system model, and a 3D layout of your system — not a sales deck.
Our in-house crew shows up on the day we promised. Daily progress photos in your inbox. Site protected. Schedule in writing.
Every panel, battery, and meter streams to your private dashboard. We watch it continuously and dispatch a crew if anything drops below spec.
We model your site load, demand charges, and TOU rate schedule. Proposal shows payback, IRR, and 25-year cashflow — not just kWh savings.
In-house PE-stamped drawings, structural calcs, Title 24 compliance, and fire-setback documentation. We carry the $5M GL and the workers' comp.
PG&E interconnection, city permits, fire marshal sign-off, and HOA — all under one accountable project manager. No finger-pointing between trades.
W-2 NABCEP-certified installers, drug-tested and OSHA-trained. GAF Master Elite. Daily progress reports. We work nights and weekends to keep your business open.
Asset management, demand-response enrollment, O&M contracts, and bi-annual performance audits. Your system is a financial asset — we treat it like one.
Real customers. Real California homes. Real quotes — no spin, no AI-generated reviews.
“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.”

Solar power refers to the energy derived from the sun's rays. It is a form of renewable energy that harnesses the sun's abundant and freely available resources to generate electricity. Solar power is obtained through the use of solar panels or photovoltaic (PV) cells, which convert sunlight directly into usable electrical energy.
Solar power systems typically consist of multiple solar panels, also known as solar modules or solar arrays, which are installed on rooftops, open spaces, or even integrated into building materials. These panels contain an array of PV cells made from semiconductor materials, usually silicon. When sunlight hits the cells, it excites electrons and creates a flow of direct current (DC) electricity, which an inverter then converts to alternating current (AC) for your home or business.
Solar batteries play a vital role in maximizing the benefits of solar energy. These innovative devices store the excess electricity generated by solar panels, allowing you to use them during periods of low sunlight or at night. With solar batteries, you can ensure a continuous power supply for your home and ride through PSPS events and peak TOU rates.
Yes. Solar energy offers a versatile and sustainable solution for both residential and commercial properties. Whether you own a home or a business, harnessing the power of the sun can provide numerous benefits. Solar panels can be installed on rooftops, parking structures, or open land, generating clean energy wherever you have space.
