You Have Questions – We Have Answers – NOW WITH 35% MORE STORAGE & 20 YEAR LIFETIME!
How Much Will I Save & How Much Does It Cost (in PG&E territory)?1
|Solar+Storage Savings||Raw Cost||Final Cost||Simple Payback Years||Payback with EV||kwh generated per year|
|SGIP rebate rate $/wh||$0.20||EV2 rate||Does not need EV to qualify – only solar+storage|
To use this table, find your annual electric use in kwh from your utility bill. Find the system in this table with generation at or more than your annual use (far right column). Keep in mind any future additions to electric use such as EVs or switching to electric appliances will likely increase your use. That line is the system with the best value.

Residential and commercial energy rates are changing dramatically. ALL the utilities are switching from peak rates during the day (typically noon-6) to evening peak (4-9pm). LESS THAN 20% OF SOLAR POWER IS DURING THESE NEW PEAK PERIODS! This means with the new rates, the value of solar only is ONLY 1/2 OF THE CURRENT VALUE!! Energy storage SOLVES this, by storing your solar generated energy and providing it to your loads during the peak periods typically DOUBLING THE VALUE OF YOUR SYSTEM. Custom Power Solar keeps up to date on ALL rate schedules in California, and can provide you the BEST VALUE in your solar+storage system by giving you the MOST return for your investment.
Cash rebates are available for a limited time on battery storage solar systems. Rebates range from $3,700-$30,000 for typical residential systems. With these rebates a solar system with battery backup is less than a solar-only system. The rebates are limited – first come, first served! Call now for a free estimate.
Cash Credits and Community Choice Aggregation (CCAs)
You may have found you are now being served by a CCA such as Marin Clean Energy, Peninsula Clean Energy, or the new East Bay Community Energy. A major difference in the CCAs is that under NEM rules, you will be paid FULL CREDIT for any power you return to the grid. This makes it MUCH more advantageous for solar+storage customers to export power back to the grid. Don’t just zero your bill, make $ every year with excess power exported to the grid, and help power your neighborhood!
Now with Lithium Iron Phosphate battery storage
Lithium batteries provide longer life, smaller size and weight, and higher efficiency than lead-acid batteries. We now use Lithium Iron Phosphate batteries – the safest in the industry.
Solar Power with Battery Storage + Save $
A battery storage 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 earthquake. IN ADDITION, the storage system saves you $ – as much as 100% MORE than your solar savings by shifting energy use from low rate periods to high rate periods.
With Custom Power Solar, you can have a custom solar system 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. Contact us 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.
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 – 10 years. Contractor provides 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.
