Even with solar panels on your roof, you may still be watching your electricity bill climb every time the sun goes down. That is because most solar-only systems export excess midday power to the grid at low net metering rates, then pull expensive electricity back at peak pricing in the evening. Solar battery storage for California homes closes that gap entirely, letting you store the energy your panels produce during the day and use it at night when SCE rates are highest. Power Pros Electric has been installing battery storage systems for Murrieta and Southwest Riverside County homeowners for over 40 years, and this guide walks through how the technology works, what it costs, and what you stand to save.
What Is Solar Battery Storage and How Does It Work?
Think of a home battery storage system as a savings account for the electricity your solar panels produce. During the sunniest hours of the day, your panels often generate more power than your household can immediately use. Without storage, that surplus flows back to the utility grid under net metering at a credit rate that has dropped significantly under California's NEM 3.0 rules. With a battery, that same surplus is captured and held inside your home, ready to be deployed the moment your panels stop producing or the grid rate spikes.
The battery system connects between your solar inverter and your home's main electrical panel. A charge controller monitors solar production and home consumption in real time, directing excess power into the battery until it reaches full capacity. From there, a smart energy management system determines when to draw from the battery versus the grid, automatically optimizing for the lowest possible cost based on your utility's Time-of-Use rate schedule.
When a grid outage occurs, the battery switches to backup mode within milliseconds, keeping your essential circuits powered without any manual intervention required. This is a critical distinction from solar-only systems, which are legally required to shut down automatically during outages to protect utility workers.

How Solar Battery Storage Works Step by Step
- Solar panels generate DC electricity from sunlight throughout the day, often producing more than the home can use during midday hours.
- The inverter converts DC to AC for immediate home use. Any surplus is directed to the battery rather than being exported to the grid at a low net metering credit rate.
- The battery stores the surplus in lithium-ion cells and holds it until the home needs it, typically in the evening when SCE peak pricing begins.
- The energy management system discharges the battery automatically during the 4 PM to 9 PM peak window, supplying your home's load without drawing from the grid at the highest rates of the day.
- During a grid outage, the battery instantly switches to backup mode, keeping designated circuits or your entire home powered for hours or longer depending on battery capacity and usage.
Types of Home Battery Storage Systems for California Homes
Not every battery system is built the same way. The right choice for your home depends on your energy usage, whether you have existing solar, your outage protection goals, and your budget. Here is how the most common battery technologies compare for residential use in California.
The most common type for residential solar storage. Compact, efficient, and long-lasting with 10 to 15 year lifespans. Tesla Powerwall, Enphase IQ, and Franklin WH all use lithium-ion chemistry.
A lithium-ion subtype with superior thermal stability and cycle life (3,000 to 6,000 cycles). Increasingly preferred for whole-home backup applications. Used in Tesla Powerwall 3 and many commercial systems.
Lower upfront cost but shorter lifespan (3 to 7 years), lower depth of discharge, and significantly more physical space required. Rarely recommended for new residential solar installations in California.
Emerging technology with excellent long-term cycle life. Still primarily used in commercial applications. Not yet cost-competitive for most residential solar storage projects in Murrieta.
For most Murrieta homeowners, a lithium iron phosphate system like the Tesla Powerwall 3, Enphase IQ Battery 5P, or Franklin WH delivers the best combination of performance, warranty coverage, and long-term value. Power Pros Electric assesses your specific load profile and recommends the right system during your free consultation.
How Solar Battery Storage Reduces Energy Costs for California Homes
California's utility rate structure is one of the most expensive in the United States, and SCE's Time-of-Use plans make the evening hours significantly more costly than midday. A solar-only system helps during the day, but the hours when your family actually uses the most energy, cooking dinner, running the HVAC, watching TV, and charging devices, are the same hours when the grid charges the most.
Battery storage solves this timing mismatch directly. By charging the battery during midday solar surplus and discharging it from 4 PM to 9 PM, you effectively shift your consumption from the most expensive rate period to a period where your own stored energy costs you nothing. Over the course of a year in Murrieta, this shift can save a household between $500 and $1,500 depending on system size, household usage, and your specific SCE rate plan.
Solar Battery Storage for California Homes Under NEM 3.0
California's updated Net Energy Metering 3.0 rules changed the economics of solar significantly. Under NEM 3.0, the export credit rate that SCE pays for surplus solar power has dropped substantially compared to what homeowners received under previous programs. This means that exporting excess solar to the grid is far less financially rewarding than it used to be. Battery storage is the direct response to this policy change: instead of exporting surplus at a low credit rate, you store it and use it yourself at full value during the peak window.
For homeowners who installed solar before NEM 3.0 and are still on legacy net metering, adding battery storage still improves overall system performance and adds critical outage protection value. For new solar installations going forward, battery storage is essentially required to make the full financial case pencil out the way it once did. The case for solar panels in California is still strong, but battery storage is now the complement that makes a solar investment fully optimized.
Real-World Battery Storage Savings Breakdown for a Typical Murrieta Home
| Savings Mechanism | How Battery Storage Generates It | Estimated Annual Value |
|---|---|---|
| Peak-Rate Avoidance | Battery discharges during SCE's 4-9 PM window instead of drawing from the grid at the highest TOU rates | $500 - $1,200 per year |
| NEM 3.0 Self-Consumption | Using stored solar surplus at home rather than exporting at the low new export credit rate | $300 - $800 per year |
| Demand Charge Reduction | For homes on demand-based rate plans, battery prevents high-draw spikes that trigger demand charges | Varies by rate plan |
| Outage Avoidance | Prevents food spoilage, hotel costs, generator fuel costs during PSPS and weather outages | $200 - $1,000+ per outage event |
| Home Value Premium | Homes with solar-plus-storage command a measurable premium in the California real estate market | $10,000 - $25,000+ in appraised value |
Backup Power: Why Battery Storage Matters More Than Ever in Murrieta
Wildfire-related Public Safety Power Shutoff events have become a recurring reality for Riverside County homeowners. When SCE proactively de-energizes transmission lines during high fire danger conditions, the outages can last anywhere from several hours to multiple days. A solar-only system provides no backup power during these events since it must disconnect from the grid for safety reasons. A battery storage system, however, automatically islands your home from the grid and keeps power flowing to whatever circuits you designate as backup loads.
What Can a Home Battery Power During an Outage?
| Battery Capacity | What It Typically Covers | Estimated Backup Duration |
|---|---|---|
| 10 kWh | Refrigerator, lights, Wi-Fi, device charging, medical equipment | 12 to 24 hours on essential circuits |
| 13.5 kWh (one Powerwall 3) | All of the above plus HVAC for shorter periods | 24 to 36 hours on partial home load |
| 27 kWh (two batteries) | Full home including central air, EV charging at reduced rate | 24 to 48 hours, indefinitely with solar recharging |
When battery storage is paired with solar panels, the battery can recharge each day using solar production during the outage, extending backup protection from a one-time charge to continuous coverage for as long as the sun rises. For homeowners who want additional redundancy beyond what a battery alone provides, a whole-home standby generator can be added alongside the battery system to cover extended cloudy-day outages or very high-demand loads.
Power Pros Electric's Battery Backup Program includes a full assessment of your home's critical loads so we can right-size your battery system for the outage duration and the appliances that matter most to your household.
Incentives That Make Solar Battery Storage More Affordable
Between federal, state, and utility incentive programs, the net cost of a home battery storage system is significantly lower than the sticker price. Here is a current overview of what Murrieta homeowners can access. For a complete and up-to-date list of all programs available in your area, DSIREUSA.org maintains a comprehensive database of state and federal incentives.
| Incentive Program | How It Works | Eligibility |
|---|---|---|
| Federal ITC (30%) | Deduct 30% of the total battery and solar installation cost from your federal tax liability. Battery qualifies whether installed with solar now or added to an existing solar system. | Any homeowner with federal tax liability; 30% rate through 2032 |
| California SGIP Rebate | Self-Generation Incentive Program pays a per-kWh rebate for residential battery storage. Rebate tiers favor low-income households and high fire-risk zones, both of which apply to many Riverside County addresses. | SCE and other CA utility customers; rebate amounts vary by tier |

Battery storage systems connect directly to your home's main electrical panel, and some homes require panel upgrades before a battery can be safely installed. Most Murrieta homes built before 2000 have 100-amp panels that may not have sufficient capacity for both a solar interconnection and a dedicated battery circuit. A main panel upgrade to 200-amp service resolves this and qualifies for the same 30% federal tax credit when completed as part of a solar-plus-storage project.
Once your battery is installed and storing tens of thousands of dollars worth of electronics, whole-home surge protection becomes an important companion. Voltage spikes from utility switching, lightning, or motor-driven appliance cycling can damage battery management systems and inverters. A whole-home surge protector installed at the main panel provides a low-cost layer of protection for your entire electrification investment.
Battery Storage as Part of a Fully Electrified Home
Battery storage is one component of a complete home electrification system. Power Pros Electric installs and integrates every piece of the puzzle, and we plan each project so the components work together efficiently rather than creating conflicts or compatibility issues down the road.

Frequently Asked Questions: Solar Battery Storage for California Homes
Yes. Home battery systems like the Tesla Powerwall 3, Enphase IQ Battery, and Franklin WH automatically switch to backup mode when they detect grid loss, typically within milliseconds. If you also have solar panels, the battery will continue recharging each day from solar production, extending your backup coverage indefinitely as long as there is sunlight. A single 13.5 kWh battery can cover essential home circuits for 24 to 36 hours on a single charge, and two batteries can power a full home for 48 hours or more.
In most cases, yes. Battery storage can be retrofitted to existing solar installations, though the process depends on your current inverter type. String inverter systems may require an additional AC-coupled battery inverter, while microinverter systems from Enphase pair natively with the IQ Battery lineup. Power Pros Electric assesses your existing system during the consultation and recommends the most efficient integration path. Adding battery storage to an existing solar system still qualifies for the 30% federal ITC under current IRS guidance as long as the battery charges exclusively from solar.
Most lithium-ion residential battery systems carry a 10-year manufacturer warranty and will continue operating beyond that with some capacity degradation. Lithium iron phosphate batteries, used in the Tesla Powerwall 3 and several other systems, typically cycle 3,000 to 6,000 times before reaching 80% of original capacity. For a system that cycles once per day, that translates to 8 to 16 years of useful life at full warranty performance. Power Pros Electric only installs battery systems from manufacturers with established U.S. warranty service and a track record of honoring claims.
Yes. Residential battery storage systems qualify for the 30% federal Investment Tax Credit through 2032 when they are charged exclusively by solar energy. If you are installing solar and battery storage together in a new system, the entire project cost, including panels, inverters, battery, and labor, qualifies for the credit. If you are adding a battery to an existing solar system, the battery cost qualifies as long as the installation is completed correctly and documented to show exclusive solar charging. Power Pros Electric provides all necessary documentation for your tax professional.
For essential circuit backup covering a refrigerator, lights, Wi-Fi, and device charging, a single 10 to 13.5 kWh battery is typically sufficient for 24 to 36 hours. For whole-home backup that includes central air conditioning, two batteries (27 kWh) are generally recommended. Homes that want indefinite backup coverage, meaning they want to ride out multi-day outages by recharging from solar each day, typically need enough battery capacity to cover one full night's worth of critical loads. Power Pros Electric performs a load analysis for each home to determine the right battery count before making any recommendation.
A battery backup system activates instantly and silently, runs on stored solar energy, requires no fuel, and produces no emissions. A standby generator takes a few seconds to start, runs on natural gas or propane, and can run indefinitely as long as fuel is supplied. For most Murrieta homeowners, battery storage covers the vast majority of outage scenarios efficiently and quietly. A standby generator is the right addition for homeowners who experience extended multi-day outages where solar recharging cannot keep up with home energy demand. Power Pros Electric installs both and can design a combined system that covers every outage scenario your household might face.
