Electrical, Solar, EV & Battery Electrician in Folsom
Folsom has one of the highest solar adoption rates in the Sacramento region — and since PG&E’s NEM 3.0 took effect, the conversation has shifted. Export rates dropped significantly, and homeowners who installed solar before 2023 are now asking about batteries. Homeowners who haven’t gone solar yet are running new numbers. Either way, the answer usually involves pairing panels with storage, and that kind of integrated work requires an electrician who understands the full system — not just the panels on the roof. That’s what we do.

What We Handle for Folsom Homeowners
From 1990s Empire Ranch homes adding their first EV charger to newer Folsom Ranch builds optimizing a solar-plus-storage setup, here’s the full scope of what we do.
Battery Storage Systems
Under PG&E’s NEM 3.0, storing the solar energy you generate — rather than exporting it at reduced rates — is the move that actually pencils out. We install and integrate Tesla Powerwall, Enphase, and other battery systems tied cleanly into your existing solar or as part of a new solar install. California’s SGIP rebate program can offset a meaningful portion of the cost, and we’ll walk you through what you qualify for.

Solar Panel Installation
NEM 3.0 changed the economics, but solar in Folsom still works — especially when it’s sized and designed correctly for how you actually use power. Because we’re electricians first, the interconnection to your panel is done right, the permit drawings meet PG&E’s requirements, and the system integrates cleanly with any future battery or EV charger additions.

Panel Upgrades
Folsom’s 1990s and early-2000s homes in Empire Ranch and Willow Creek typically have 200-amp panels that are reaching the age where breakers fatigue and capacity starts to matter. If you’re adding solar, a battery, and an EV charger, panel load capacity needs to be assessed — not assumed. We do the math, tell you what’s actually needed, and upgrade only when it makes sense.

EV Charger Installation
Folsom’s tech-adjacent workforce drives strong EV adoption, and a Level 2 home charger is one of the highest-value electrical additions you can make right now. We handle the 240V circuit, panel load assessment, charger installation, and permit with the City of Folsom — and if you’re also adding solar or battery, we scope it all together so nothing needs to be revisited.

New circuits for kitchen appliances or home offices, outlet additions, whole-home rewiring for older sections, and anything the remodel uncovered — permitted, inspected, and done clean. Residential electrical in Folsom →

How We Approach Work in Folsom
- NEM 3.0 Fluency: PG&E’s NEM 3.0 changed what a solar-only install looks like in Folsom. We design systems that account for the new export rate structure — whether that means sizing a battery into the project from the start or retrofitting storage to an existing array. You get a system that performs the way the numbers promised.
- HOA-Ready Documentation: Many Folsom neighborhoods — Empire Ranch, Broadstone, Serrano-adjacent communities — have HOAs with exterior installation guidelines. We provide permit drawings and placement documentation that gives your HOA what it needs to approve the project without delay.
- Backup Power for Wildfire Season: Folsom sits near WUI-designated areas, and PG&E’s Public Safety Power Shutoff (PSPS) events are a real seasonal concern. A battery storage system isn’t just a solar optimization tool here — it’s also your household’s answer to a multi-day outage. We design systems that handle both jobs.
- C-10 License, Full Scope: The C-10 electrical contractor license covers the complete system — panel to solar inverter, battery tie-in to EV circuit. Not every company doing solar in Folsom holds it. We do, and we’re fully insured on every job.
- One Team, One Project: Solar, battery, EV charger, panel work — one contractor scopes it all, pulls one permit set, and finishes it as one job. No gaps between trades, no finger-pointing if something needs adjustment.

Quality Work. Honest Numbers. Ready When You Are.
Under the Sun Solar & Electric brings C-10 licensed expertise to every project in Folsom — whether it’s a straightforward panel assessment or a full solar-battery-EV system design. We’ll give you a clear picture of what your home needs, what it’ll cost, and what you’ll get out of it. No pressure, no overselling, no out-of-town crews.
Folsom is in PG&E territory, and NEM 3.0 — which took effect in April 2023 — reduced the rates PG&E pays for exported solar energy by roughly 75% compared to NEM 2.0. That means a solar-only system that exports heavily during the middle of the day earns far less credit than it used to. The practical response is to pair solar with battery storage: charge the battery during peak generation, then draw from it at night instead of the grid. We design Folsom solar systems with this in mind from the start, and we can also retrofit storage onto existing arrays. Call 916-899-3062 if you want to run the numbers on your situation.
For most Folsom homeowners on PG&E, yes — especially those who installed pre-NEM 3.0 and are approaching the end of their original 20-year NEM 2.0 grandfathering period. Adding a battery lets you capture more of the energy you generate, reduce grid draw during evening peak rates, and have backup power during PSPS outages. California's SGIP battery rebate program can offset a significant portion of the installation cost, and the federal ITC tax credit applies to battery storage added to an existing solar system. We can assess your current setup and show you what a storage addition would actually do for your bill. Request a free assessment online or call 916-899-3062.
Yes. California law (Civil Code 714) limits HOAs from outright banning solar, but they can require placement that's not visible from the street — which sometimes affects system sizing or orientation. We've worked with HOA approval processes in Folsom and can provide the permit drawings and documentation your HOA needs to review and approve the install. We'll also tell you upfront if an HOA's requirements would materially affect the system's performance.
Parts of Folsom — particularly areas near Folsom Lake and toward the foothills — fall within or adjacent to WUI (Wildland-Urban Interface) designations, and PG&E has issued PSPS shutoffs affecting Folsom customers in recent years. From an electrical standpoint, this makes battery storage a practical investment beyond just solar optimization: a properly sized battery can carry essential loads (refrigerator, lights, medical equipment, phone charging) through a multi-day outage. It also raises the importance of using a C-10 licensed contractor for any panel or solar work, since WUI-area installations are subject to additional inspection scrutiny.
Electrical permits in Folsom are handled by the City of Folsom Building Division. Most standard jobs — panel upgrades, EV charger installations, solar interconnections — go through the city's online permit portal and are typically processed within a few business days for straightforward scopes. We handle the application, any required plan check drawings, and final inspection scheduling. You don't need to manage any of it. Call 916-899-3062 or get a free estimate online.
