First light, and the meter turns

A solar array is not bolted onto a house. It is the morning the house stops only spending and starts earning — the hour the meter turns and begins to run the other way.

We design and install rooftop solar across the Valley — Arcadia, Paradise Valley, Gilbert, the neighborhoods where the sun is a resource nobody was collecting. Each system is sized to one roof, one bill, one direction the panels can face.

Panels, an inverter, and — if you want the sun after dark — a battery. Nothing on the plan the roof and the numbers didn't ask for. We are on your roof for a day or two, and on your bill for twenty-five years.

How we size a system

Solar noon

For six hours a day, the desert does nothing but give.

Phoenix gets more usable sun than almost anywhere in the country. Your roof isn't shelter from it — it's the best south-facing collector you already own. We just finish the wiring.

Keep it after dark — battery storage

25-year net savings

vs. doing nothing

Modeled on a real Gilbert home — 8.4 kW system, about $205 average monthly bill, APS residential rate, the 30% federal tax credit applied. Your roof, shade and usage move every one of these figures — which is exactly what a free estimate is for.

What we install

Three ways to keep the sun.

The install

Five steps, one roof.

Solar is permitted once and wired once. The order is fixed — the city and the utility each have to sign before the meter turns. Here is the whole path, first call to first kilowatt.

01

Assessment

We pull your last twelve months of usage, read the roof — pitch, direction, shading — and confirm your utility and rate plan. The design answers your bill, not a brochure.

02

Design

Engineering lays out the array, specs the panels and inverter, and models production hour by hour. You get a real savings estimate and a firm price before anything is ordered.

03

Permitting

We carry the city permit, the HOA submittal, and the utility interconnection application. Most of the calendar between signing and installing is paperwork we handle — not work on your roof.

04

Installation

Mounts, panels, inverter and wiring. A typical home is one to two days on the roof, and we leave it watertight and the array flush — no dangling conduit, no afterthought.

05

Activation

Final city inspection, then the utility grants Permission to Operate. The system switches on, the meter starts counting backward, and the first kilowatt is yours.

Selected work

Three roofs, three answers.

After the meter turns

What owners say.

5.0 — from thirty-one Valley homeowners

Our first full APS bill after activation was eight dollars. Eight. Firstlight modeled it almost to the dollar a year earlier.
The Reyes family · Gilbert March 2026

They talked us out of a bigger system than we needed. Who does that? The array covers our use and not one panel more.
Dana K. · Chandler February 2026

When the grid went down in July, our block was dark and our kitchen wasn't. The battery just took over — we noticed only when a neighbor knocked.
Marcus & Toni · Arcadia May 2026

Two days on the roof, flush and clean, and you can't see a wire. It looks like the house came that way.
J. Alvarez · Paradise Valley April 2026

The estimate wasn't a sales pitch, it was a spreadsheet. Payback in the sixth year — exactly as promised, so far.
Priya S. · Tempe January 2026

They handled the HOA, the city and the utility. I signed twice, and the next thing I did was watch the meter run backward.
Tom H. · Mesa June 2026

The honest number

What does solar cost in Phoenix?

A typical residential system runs $18k–$32k installed — or about $13k–$22k after the 30% federal tax credit. Most Valley homes land in the middle, and pay it back in six to nine years.
