Solar Battery Installation
What Is Solar Battery Installation?
Solar battery installation covers installing home or business battery energy storage — genuinely different equipment than the standby generators covered on our Generator Installation page, though it solves a related real problem: backup power and energy resilience. A battery stores solar energy your system already produces, using it later instead of selling it back to the grid for very little.
This matters specifically in California: the 2023 shift to NEM 3.0 changed how solar exports are credited, making battery storage genuinely more valuable here than it used to be. Bright Right Electric installs solar battery systems for homes and businesses across Sonoma County, as a CSLB-licensed electrical contractor (#1156335) based right in Rohnert Park.
Solar Battery Installation
Our Process
A solar battery installation moves through the same core stages:
01
Assessment
We review your existing solar (if any), your usage patterns, and your backup goals.
02
Sizing
We help you decide between whole-home and partial-home (essential-circuits) backup coverage.
03
System Design
We design the battery, backup gateway, and any needed panel work for your specific home.
04
Installation
We install the battery and connect it correctly to your solar system and panel.
05
Commissioning
We test the complete system, including backup switchover, under real conditions.
06
Walkthrough
We show you how to monitor and configure your battery's charge/discharge settings.

How Much Does Solar Battery Installation Cost?
A single Powerwall-class battery typically runs $12,000–$16,500 installed, depending on your electrical panel and whether it's paired with new or existing solar. Multi-unit systems for larger homes commonly run $22,000–$30,000 for two units.
Solar Battery Installation
The Real NEM 3.0 Math
This is genuinely worth understanding before assuming solar alone is enough: under NEM 3.0, exported solar typically earns only around $0.05 per kWh, while peak import electricity can cost $0.40 or more per kWh. A battery stores your own midday solar production and discharges it during expensive evening peak hours instead of selling it back for pennies — closing that gap significantly.
Solar Battery vs. Generator: An Honest Comparison
This is a real, fair question worth answering directly rather than picking a side:
- Standby generator — typically $5,000–15,000 installed, can run indefinitely as long as fuel is available, but produces emissions and requires fuel.
- Battery storage — typically $12,000–16,500 installed, limited by stored capacity, but produces zero emissions, needs no fuel, and recharges automatically from solar.
Neither is universally better — a generator suits longer outages where fuel is available, while a battery suits shorter outages and genuinely improves solar economics under NEM 3.0 at the same time.
How Big of a Battery Do You Need?
It depends on your real backup goals: a single battery in the Powerwall class (roughly 13.5 kWh capacity, 11.5 kW continuous output) can cover whole-home backup for many mid-size homes. Larger homes, or homes needing full HVAC and EV-charging coverage, typically need two or more units.
Does a Battery Still Qualify for a Tax Credit?
This is genuinely unclear right now, and worth being honest about rather than guessing: current sources disagree. Some state no federal credit applies to a current purchase, since the 30% residential solar credit expired December 31, 2025. Others state it still applies when a battery is paired with solar. We'd rather confirm this directly for your specific situation than give you a confident-sounding wrong answer.
The New 2026 Fixed Charge, Explained
This is worth knowing if you haven't seen your latest bill yet: California's major utilities implemented a flat monthly connection fee in 2026 — the Income-Graduated Fixed Charge — which can't be offset by solar credits, though volumetric rates dropped somewhat in exchange. A battery configured for peak-hour export can help offset this through arbitrage credits, but it's a real, additional factor worth understanding as part of your overall solar economics.

What Rohnert Park Customers Are Saying
"This is the most professional company I have ever worked with. I am a difficult person and hard to please (I have really high standards (as a retired science teacher) and I am skeptical of workmen and I'm a perfectionist!). Bright Right is currently working on the 3rd job I have hired them for – everything has gone smoothly, no stress at all!!! They are so friendly and so courteous. Rick and Dustin are an effective team with their two unique personalities – both very upbeat, serious, and kind. They explain everything in detail and answer all my questions (I am hyper-concerned about my property), and they are basically experienced, conscientious electricians you can trust."
— Nora Parker · Google Review
"I recently hired Dustin for some electrical work at my home, and I couldn't be happier with the results. He installed a high-quality bathroom fan, finished installing several outlets around the house, and completed a new electrical panel installation. From start to finish, Dustin was professional, knowledgeable, and clearly takes pride in doing the job right. The new panel installation was the bigger job, and Dustin handled it with real expertise. Everything was organized, labeled, and done to a very high standard, which gave me a lot of confidence in the safety and quality of the work."

"Bright Right did the electrical for our kitchen remodel and we couldn't be happier, we have since then added an EV with them and they were as good as the first time. Highly recommend!"
— Joey Evans · Google Review
"Shout out to Dustin Fildes, the electrician they sent to do the work at my house. You can tell he takes pride in his work. He's a very professional and very friendly. Individual would absolutely recommend Bright Right Electric and specifically Dustin to all my family and friends. Thank you Bright Right"

Questions
Frequently Asked Questions
How much does a home battery cost installed?
A single Tesla Powerwall 3 typically costs $12,000 to $16,500 installed in California, depending on electrical panel requirements and whether it's paired with new or existing solar. Multi-unit systems for larger homes commonly run $22,000 to $30,000 for two units.
Is a solar battery worth it under NEM 3.0?
For most California homes with solar, yes — exported solar typically earns only around $0.05 per kWh, while peak import electricity can cost $0.40 or more per kWh. A battery stores midday solar production and uses it during expensive evening peak hours, closing that gap significantly.
Solar battery vs. generator — which is better for backup power?
It depends on your priorities. A whole-home standby generator (typically $5,000-15,000 installed) can run indefinitely as long as fuel is available. A battery is limited by its stored capacity but produces no emissions, requires no fuel, and recharges automatically from solar.
Does a home battery still qualify for a tax credit?
This is genuinely unclear as of current information. Sources disagree, with some stating the 30% federal residential credit expired December 31, 2025 and no longer applies, while others state it still applies when paired with solar. We confirm this directly for your specific situation rather than guessing.
How long does a home battery last during an outage?
It depends on your battery's capacity and what you're powering. A single Powerwall-class battery (roughly 13.5 kWh) can cover essential circuits for many hours, though whole-home coverage during an extended outage may require multiple units.
Tesla Powerwall vs. Enphase battery — which is better?
The Tesla Powerwall 3 offers 13.5 kWh with an integrated inverter, while Enphase batteries are modular, sold in smaller increments that stack for flexibility. Neither is universally better — the right choice depends on your specific home and goals.
How many batteries do I need for whole-home backup?
It depends on your home's size and backup goals. A single battery in the Powerwall class can cover whole-home backup for many mid-size homes, while larger homes or those needing full HVAC and EV-charging coverage typically need two or more units.It depends on your home's size and backup goals. A single battery in the Powerwall class can cover whole-home backup for many mid-size homes, while larger homes or those needing full HVAC and EV-charging coverage typically need two or more units.
What is NEM 3.0?
NEM 3.0 is California's current net billing tariff, which significantly reduced how much homeowners are credited for solar energy exported to the grid compared to the previous system, making battery storage genuinely more valuable for maximizing solar savings.
Can I add a battery to my existing solar system?
Yes — a battery can typically be added to an existing solar system, connecting to your current inverter setup with the appropriate configuration for your specific equipment.
What is the California fixed monthly utility charge in 2026?
California's major utilities implemented a flat monthly connection fee in 2026, which cannot be offset by solar credits, though volumetric electricity rates dropped somewhat in exchange. A battery configured for peak-hour export can help offset this charge through arbitrage credits.

Electrical Panel Upgrades in Rohnert Park
Replacing an undersized or obsolete panel is the most common job we perform in Rohnert Park, and it's the one that unlocks everything else. If your home still runs original 100-amp service, a Federal Pacific Stab-Lok, or a Zinsco panel, you're working with equipment engineered for a much smaller electrical load — and, in the case of those two brands, with a documented history of breakers that fail to trip. Upgrading to 200-amp service makes EV charging, battery backup, heat pumps, and modern appliance loads possible without constantly tripping breakers. We size the new service to what your household actually needs, pull the permit, coordinate the PG&E disconnect and reconnect, and meet the inspector for final sign-off.
EV Charger Installation in Sonoma County
Bright Right installs Level 2 home charging sized to your vehicle and, just as importantly, to your panel's actual available capacity. We run the dedicated 240-volt circuit, mount and commission the charger, and handle the permit — installing Tesla Wall Connectors, universal J1772 and NACS units, and hardwired or plug-in setups across Rohnert Park, Petaluma, and Santa Rosa. The detail most homeowners don't hear until it's too late is that many Sonoma County panels can't support a Level 2 charger without a service upgrade first, so we run a load calculation before you buy equipment, not after. We can also pre-wire a second circuit if a second EV is anywhere in your future.
Standby Generators & Backup Power
Public safety power shutoffs are a fact of life in Sonoma County, and so are winter storms that take lines down in the hills. We install whole-house standby generators with automatic transfer switches that pick up the house within seconds of an outage, wire inlets and manual transfer switches for portable generators, and add whole-house surge protection so your equipment isn't damaged when the utility comes back online. We'll also tell you honestly which tier makes sense — not every home in Cotati or Penngrove needs a whole-house unit when a critical-loads panel that keeps the refrigerator, well pump, internet, and a few circuits alive costs a fraction as much.
Solar & Battery Systems
We handle new photovoltaic installation, battery storage, system additions, and remove-and-replace work when a roof needs attention or a system has failed — plus service on existing arrays that aren't producing what they should. If you inherited a solar system with the house and nobody can tell you how it's wired or whether it's still under warranty, we can assess it and give you a clear picture. Battery storage in particular has changed the math for Sonoma County homeowners: between shifting utility rate structures under NEM 3.0 and the frequency of outages, a battery paired with existing solar is often a better investment than adding more panels.
Interior & Exterior Lighting
Recessed and can lighting, full LED retrofits, under-cabinet lighting, dimmer and smart-switch installation, fixture and chandelier hanging, landscape lighting, and security and motion-sensor lighting for homes across Rohnert Park and the University District. On the commercial side we handle lighting retrofits for offices, retail spaces, and warehouses along the Commerce Boulevard corridor, including the fixture and control changes that come with California Title 24 compliance. Lighting is one of the few electrical upgrades where the difference is immediately visible, and it's frequently the cheapest way to make a dated room feel finished.
Electrical Troubleshooting & Repair
Breakers that trip for no obvious reason, circuits that go dead, lights that flicker when the dryer starts, outlets that no longer hold a plug, GFCIs that won't reset, a faint burning smell you can't locate. These are the calls where experience shows. We trace a fault to its real source instead of swapping parts and billing for guesses, which is why our repairs hold and why we get called in behind other contractors who couldn't find the problem. In older Sonoma County homes the cause is often a failing backstab connection, a corroded neutral, a rodent-damaged run in a crawlspace, or a decades-old junction box buried behind drywall.
Custom Homes & New Construction
Full electrical for ground-up residential builds, major remodels, and additions throughout Sonoma, Marin, and Napa County — load calculations and plan review, service and meter setup, rough-in, trim, and final inspection. We work with general contractors, designers, and owner-builders, and we're comfortable on high-end custom projects near Sonoma State University where the lighting design, low-voltage layout, and smart controls all have to be coordinated before a single wire goes in. Getting the details right at rough-in is what keeps a home safe and functional for the next forty years — and it's far cheaper than fixing it after the drywall is up.
Commercial Electrical & Tenant Improvement
Service upgrades, panel and subpanel work, dedicated circuits for equipment, lighting retrofits, EV charging for employee and customer parking, and full tenant-improvement electrical for offices, retail, restaurants, and light industrial space along Redwood Drive and beyond. We understand a commercial job runs on someone else's schedule, so we work around business hours when the scope requires it. From a single dedicated circuit to a complete build-out, you get one licensed contractor coordinating permits, PG&E, and inspection — with clear pricing and a clean, code-compliant result.
