Residential and Commercial Solar System Services
Custom Power Solar specializes in solar power systems with battery backup. We offer a range of products from smartphone chargers to on-grid and off-grid solar power systems with battery backup. Never go without power again!
Cash rebates are available for a limited time on battery storage solar systems. Rebates range from $4,000-$30,000 for typical residential systems. With these rebates a solar system with battery backup can be installed for the LESS cost than a solar-only system. Please note, the SGIP program rebate program is currently undergoing significant change, which is increasing the number of battery system rebates, but the final conditions have not been set, and not all applicants will receive rebates during any calendar year. The rebates are limited – first come, first served! Call now for a free estimate.
Now with Lithium battery backup
Lithium batteries provide longer life, smaller size and weight, and higher efficiency than lead-acid batteries.
Solar Power with Battery Backup
A battery backed-up solar power system uses a bank of batteries that stores power from your solar array. When the grid fails and when electric power is no longer being fed to your home or business, the batteries and solar array supply power. In the event of a power outage, battery power is restored by solar power each day. With careful management you can operate indefinitely off grid.
In the San Francisco Bay Area, we know another large earthquake is inevitable – a battery backup solar power system gives you the peace of mind to know you will have power to run your home or business in the event of a power outage, whether just a simple line failure or as a result of a major eathquake.
With Custom Power Solar, you can have a custom solar system installed for $0 down. And not only can you reduce or zero your power bill, you can put money in the bank in the very first year! We can help you apply for a substantial rebate for a battery energy storage system from your local utility company. There is a 30% Federal Investment Tax Credit, which can be applied to reduce your property taxes under the PACE program. When you are done, you OWN your system, and YOU reap the financial benefits, plus the peace of mind that in the event of grid failure, YOU will always have power. Call us at 510-912-4662 for details!
Plug-In Hybrids and Electric Vehicles
It’s clear that the future of transportation is moving towards plug-in hybrids and all electric vehicles. A typical vehicle uses 0.25-0.35kwh per mile. With your solar system the power for your EV is free! It’s like having free gas! A typical EV owner driving an average of 40 miles per day can save almost $4000/year charging from solar and powering your home!
The battery backup system operates quickly & quietly – unlike generator systems which have to power up the generator to feed power. Time to switch may be as low as 50 -100 milliseconds.
Reduce your electric bill
To reduce your electric bill on an annual basis to zero and have a typical 1-2 day backup battery system, a good rule of thumb is take your annual electricity cost and multiply by 2.5-3 to get the watt size of the solar array. If you’re adding a plug-in vehicle, add 1kw for every 15 miles of commute. For example, if your annual bill is $3000, multiply by 2.5 to get a 7.5kw array. If you have a 30 mile round trip commute add another 2kw. The total is then 9.5kw.
Most residential systems have more than enough roof space to generate power to zero your electric bill. Modern technology has the capacity to deal with virtually any shading situation. Using Google Maps we can take your address and look at the size of your roof space to find the best fit.
A driveway, garage, or parking area can be used for solar power. In agricultural areas unused farm land, barns, warehouses, and access corridors can also be used.
Monitoring & Remote Control
You will have instant access to current production of your system through web access and see exactly how much your system is producing at any time. Our monitoring system provides access to every vital piece of information about your system, including power output and battery state. You can also operate it remotely! We use Outback Power’s OpticsRE system.
The Value of Power
PG&E is currently switching all customers to Time of Use (TOU) metering. This means the rate charged typically gets MUCH higher during peak power periods. This rate can be 3-5 times the off-peak rate if you exceed baseline. Solar power systems produce the greatest amount of power between 10:00 am and 3:00 pm in most of California. In Northern California west-facing and even north-facing roof sections will provide valuable solar generated power. Power generated during midday can be stored in the batteries, and dumped back to your home or the grid during peak hours – soon to be 4:00-9:00 pm.
Solar modules are rated to degrade less than 10% over 25 years. In real life testing, they last much longer. There are systems over 40 years old with 80% of their original power. Expect to replace the batteries once every 10 years, and inverters may need maintenance every 10 -15 years. The cost of battery replacement averages $20/month over the battery lifetime.
Components have warranties from the manufacturer, which runs 25+ years for solar modules, up to 10 years for electronics. Battery warranty is prorated based on time used based on battery manufacturer’s warranty. We provide a one year warranty on installation and labor. We will continue to monitor and troubleshoot your system for 10 years under an available 10 year service contract.
Time to Install
A typical home system can be in place in as little as a month. PG&E and permitting procedures can add up to another month, depending on the area and workload.

How We Work
Custom Power Solar has one goal in mind – satisfaction for you the customer. We help you get a solar power system at the lowest possible cost, THAT YOU OWN. First, we work with you to design the best system for your needs. We aim for a zero sum – the sun and your solar system generates enough power each year to equal the amount of power you use. We’ll help you select the best financing plan for your needs. We arrange all permitting and PG&E commissioning. We install the system – this part typically only takes 6-8 days. We’ll handle the paperwork for the permits & rebates. In the end, YOU will own the system that saves you thousands of dollars a year in energy costs. With a battery backup system, you can have substantial money in the bank the very first year. With a battery backup system, you will never go without electric power.
Made in the USA – Custom Power Solar uses components made by US manufacturers. We are dedicated to keeping solar manufacturing and installation jobs here in the USA.
