Solar Panels With Battery Backup
If you’ve opened your electricity bill lately and felt your jaw drop, you’re not alone. California homeowners across Marin, Sonoma, and Napa County pay some of the highest electricity rates in the country, and PG&E prices have swung up and down in recent years.
But what if you could take more control of your energy costs? The combination of solar panels with battery backup offers North Bay homeowners a way to use more of your own power and keep essentials running during outages.
How Can Solar Panels Reduce My Electricity Bill?
Let’s start with the basics. When you install solar panels on your home, you’re essentially building your own miniature power plant on your roof. Instead of buying 100% of your electricity from PG&E, your solar panels generate clean energy throughout the day, significantly reducing or even eliminating what you need to purchase from the grid.
Here’s how the economics break down for the typical Bay Area homeowner:
The Rising Cost Problem
PG&E’s residential rates are among the highest in the country. Since March 2026, every bill also carries a fixed monthly Base Services Charge in exchange for lower per-kilowatt-hour prices. Solar reduces the part of the bill that depends on how much electricity you buy; the fixed charge stays.
The Solar Solution
When you generate your own electricity, you stop buying that energy from PG&E. Under California’s net billing tariff, which has applied to new solar customers since April 2023, power you export earns much less than power you buy. Savings come mostly from using your own solar power, and a battery lets you use daytime solar during the expensive 4 to 9 p.m. window.
The more of your own power you use, the less of your bill depends on future PG&E rate changes.
Why Solar Panels with Battery Backup Are Essential for California Homeowners
While solar panels alone deliver significant savings, the combination of solar panels with battery backup addresses both rising costs and grid reliability concerns. Storms and PG&E Public Safety Power Shutoffs make backup power worth considering in the North Bay. When you pair solar generation with battery storage, you get dual protection: lower bills every month and continuous power during PG&E outages and Public Safety Power Shutoffs.
Why Battery Storage Changes Everything
Solar panels alone provide tremendous value, but adding battery storage to your system takes your energy independence to the next level. This is especially critical for North Bay residents who’ve experienced the frustration and disruption of PG&E’s Public Safety Power Shutoffs and weather-related outages.
The Outage Reality
In wine country and in areas prone to wildfire prevention shutoffs, an outage can last a day or more. When your power goes out, a standard solar system without batteries shuts down too. This safety feature, required by electrical codes, prevents your panels from sending electricity back to the grid where utility workers might be making repairs.
How Battery Backup Works
A battery storage system from manufacturers like Franklin, Tesla, or Enphase stores excess electricity your solar panels generate during the day. When the sun goes down, or when the grid goes down, your home automatically switches to battery power. You keep your refrigerator running, your Wi-Fi connected, your medical devices operating, and your family comfortable regardless of what’s happening with the utility grid.
Think of it like having a bank account for electricity. During sunny days, your solar panels make deposits. At night or during outages, you make withdrawals. Modern battery systems can store enough energy to power essential circuits in your home for 12-24 hours or more, depending on your usage patterns and battery capacity.
Are Solar Batteries Worth It for Power Outages?
This is the question we hear most often from homeowners considering battery storage, and the answer depends on several factors specific to your situation.
When Battery Storage Makes Strong Financial Sense
If you live in an area that experiences frequent power outages, work from home, have medical equipment that requires continuous power, or simply value the peace of mind that comes with energy security, battery storage delivers measurable value beyond just dollars and cents. Many of our customers in the hills of Marin County and rural areas of Sonoma and Napa Counties view battery backup as essential infrastructure, similar to having a solid roof or reliable plumbing.
The financial case strengthens when you consider PG&E’s Time-of-Use (TOU) rates. These rate structures charge premium prices for electricity used during peak evening hours (typically 4 PM to 9 PM) when solar panels aren’t producing. A battery system allows you to store your daytime solar generation and use it during these expensive peak hours, maximizing your savings beyond what solar panels alone can achieve.
Smart Energy Management Integration
Modern battery systems aren’t just backup power, they’re intelligent energy management platforms. When integrated with SPAN smart panels, which Ongaro & Sons is certified to install, you gain granular control over your home’s energy usage. You can prioritize which circuits receive power during an outage, monitor real-time energy production and consumption, and optimize your battery charging schedule to take maximum advantage of time-of-use rates.
This level of control represents a fundamental shift from being a passive utility customer to actively managing your home’s energy resources.
Understanding the Complete Solar-Plus-Storage System
Let’s walk through what a comprehensive solar and battery installation actually involves, so you understand exactly what you’re getting.
The Solar Panel Array
Quality solar panels convert sunlight into direct current (DC) electricity. The panels we install use monocrystalline silicon cells, which are the most efficient technology available for residential applications. These panels typically come with 25-year performance warranties and can continue producing electricity for 30-40 years or more with minimal maintenance.
Inverter Technology
Your solar panels produce DC electricity, but your home runs on alternating current (AC) power. Microinverters from manufacturers like Enphase convert DC to AC at each individual panel, providing better performance in partial shade conditions and easier monitoring of system health. Many residential installations now use microinverters or power optimizers instead of a single string inverter.
Battery Storage Units
Today’s residential battery systems, such as the Tesla Powerwall or FranklinWH aPower, typically store 10-15 kilowatt-hours of usable energy. That’s enough to run your refrigerator, lights, Wi-Fi, TV, and other essential loads for 12-24 hours. Multiple batteries can be installed for homes with higher energy needs or longer backup duration requirements.
Smart Integration and Monitoring
Modern systems include sophisticated monitoring that lets you track your energy production, consumption, and storage in real-time through smartphone apps. You can see exactly how much electricity your panels are generating, how much your home is using, and how much is being stored in your batteries or sent to the grid.
The Installation Process: What to Expect
Working with an experienced solar installer serving Marin, Sonoma, and Napa Counties ensures your system is designed and installed correctly from day one. Here’s what the process typically looks like:
Site Assessment and System Design
A professional site evaluation examines your roof orientation, shading patterns, electrical panel capacity, and energy usage history. This data informs a custom system design optimized for your specific home and goals. Factors like roof pitch, structural capacity, and available space all influence the final design.
Permitting and Approvals
Solar installations require building permits and utility interconnection agreements. Experienced installers handle all the paperwork, coordinate with local building departments, and ensure your system meets all electrical and fire codes. This typically takes 2-4 weeks depending on local government processing times.
Installation Timeline
Most residential solar panel installations are completed in 1-3 days, depending on system size and complexity. Battery installation adds another day or two. Our installation teams handle all aspects, from mounting equipment to electrical connections to final testing.
Utility Interconnection
After installation, your local utility inspector verifies the work and authorizes grid connection. This process, called Permission to Operate (PTO), typically takes 2-4 weeks. Once you have PTO, your system is fully operational and you start saving money immediately.
Ongoing Performance
Solar panels require minimal maintenance, California’s dry climate means most systems stay clean with occasional rain. Battery systems include built-in monitoring that alerts you to any performance issues, and quality components come with 10-25 year warranties for peace of mind.
Real-World Savings for North Bay Homeowners
Under California’s net billing tariff, savings come mostly from using your own solar power, and a battery lets you use daytime solar in the expensive 4 to 9 p.m. window. Your fixed monthly charge stays. Each system should be sized from your actual usage, so ask for an estimate based on your own bills.
Local Incentives and Financial Considerations
The federal tax credit for homeowner-owned solar and batteries ended for systems installed after December 31, 2025, and California’s SGIP battery rebates for PG&E customers are closed or waitlisted. From January 1, 2027, new solar systems also generally stop qualifying for California’s property tax exclusion. Financing can still spread the cost.
Many homeowners also qualify for financing options that allow you to go solar with little or no money down. When your monthly loan payment is less than your previous electricity bill, you start saving money from day one while building equity in your home.

Why the Combination Matters More Than Ever
Rising electricity rates, increasing grid instability, and growing climate concerns have created the perfect storm for solar adoption in the North Bay. The combination of panels and batteries addresses multiple challenges simultaneously:
Economic Protection: Use more of your own power and reduce how much of your bill depends on PG&E rates.
Energy Security: Keep your home powered through outages and public safety shutoffs.
Environmental Impact: Reduce your carbon footprint and support California’s clean energy goals.
Home Value: Solar systems increase property values, with research showing homes with solar sell faster and for more money than comparable properties without it.
