What we install

One crew for the whole system

Panels, batteries, EV charging, and monitoring — designed together so the pieces actually work as one.

Rooftop solar

High-efficiency monocrystalline panels engineered for your roof pitch, orientation, and shading — not a one-size catalog.

Battery storage

Keep the lights on through outages and bank cheap daytime power for the evening peak with Tesla Powerwall or Enphase.

EV charging

Level 2 home charging wired to run on the sun. Add it during install and skip a second permit and trip.

Monitoring & service

Per-panel production data in the app, plus proactive alerts. If output dips, we already know.

How it works

Three steps, zero pressure

From the first call to switch-on, you always know exactly what's next and what it costs.

01

Free design & quote

A 25-minute call and satellite roof model. You get a fixed-price proposal with real production and savings numbers — no salesperson on your couch.

02

Permits & install

We handle permits, utility paperwork, and HOA forms. Install is one or two days with our own W-2 crews — never subcontracted.

03

Inspection & switch-on

City sign-off, utility meter swap, and we flip it on together. You watch the first kilowatt-hours land in the app.

Backed for 25 years

One warranty. One company to call.

Most installers hand you three separate warranties and disappear. We cover the panels, the inverters, the racking, the roof penetrations, and the workmanship under a single 25-year promise — and we guarantee your production.

The most convincing solar review is the one written eight bills later.

The proposal matched our first three bills almost to the dollar. After 8 months we're net-positive and the crew left the roof spotless.

I got four quotes. Helio was the only one that showed the math behind the savings instead of just a monthly payment. That earned my trust.

Power went out twice this winter and we didn't notice until the neighbors texted. The Powerwall just carried us. Worth every dollar.
