A local El Cajon solar company built for the long game
We're a residential-focused solar and battery team based in El Cajon. Our whole business is designing, installing, and supporting rooftop solar for East County San Diego homeowners, not selling leads or chasing commercial contracts.
Why we started El Cajon Solar Installers
Too many East County homeowners came to us with three-year-old solar systems that were undersized, poorly designed for NEM 3.0, or bolted on by a national outfit that no longer answered the phone. We built El Cajon Solar Installers to be the opposite: a small, local, residential-only crew that actually lives in the neighborhoods we install in, from Fletcher Hills and Bostonia to Granite Hills, Rancho San Diego, and out toward Alpine.
What we do
Everything we design revolves around one question: what will actually lower your SDG&E bill and protect you from the next round of rate increases? That means honest usage analysis, right-sized systems, and clear conversations about whether battery storage makes sense under NEM 3.0 for your specific household, not a template pitch.
- Custom residential solar system design
- Tesla Powerwall and home battery backup
- Solar panel replacement, upgrades, and re-installs during re-roofs
- EV charger installation and whole-home electrification
- Long-term monitoring, service, and warranty support
The way we work
Every project starts with a real look at your last 12 months of SDG&E bills, a walk of your roof, and a plain-English conversation about what you want solar to actually accomplish. No high-pressure closes at the kitchen table, no inflated 25-year savings math, no bait-and-switch equipment swaps between the proposal and install day.
A local team you can actually call back
El Cajon based
Our office and warehouse are in El Cajon. We're not a call center in another state routing you a subcontractor.
Residential only
We don't chase warehouses or utility-scale work. Homes are our craft, every crew, every day.
Licensed & insured
California C-46 solar contractor with full general liability and workers' comp for every crew member.
Own-crew installs
Our own W-2 installers do the work, not a rotating cast of low-bid subs picked up week to week.
Honest math
We show cash, loan, and battery scenarios side-by-side using real SDG&E tariffs, not rosy assumptions.
Long-term support
Warranty claims, monitoring alerts, and roof service years after PTO, same phone number, same team.
Where we work
Our service radius covers El Cajon and the surrounding East County communities: La Mesa, Santee, Lakeside, Rancho San Diego, Spring Valley, Lemon Grove, Alpine, Jamul, Harbison Canyon, Bostonia, Granite Hills, Winter Gardens, and Fletcher Hills. If you're in a neighborhood inside SDG&E territory and we can get to your roof from 270 E Douglas Ave, we can serve you.
