What we install
Every job is permitted, inspected and backed by the same 25-year workmanship warranty.
Tier-1 410 W panels, microinverters on every panel, and our own crew on your roof. We don't subcontract the install.
Keeps the fridge, furnace fan, Wi-Fi and well pump running when the grid drops. Add it now or retrofit later.
Garage or driveway, with a load calculation first so we don't overload your panel. Panel upgrades handled in-house.
Pollen and bird droppings cost 5–8% output. We clean, inspect wiring, and watch your production for dips.

Battery backup, up close
A typical garage install: one 13.5 kWh battery on the wall, the EV charger next to it, and a critical-loads panel so the battery only powers what matters during an outage.
Savings estimator
Plain arithmetic, no email required. Your written quote replaces these numbers with ones based on your actual roof.
This is an estimate. It assumes $0.17/kWh power, 1,350 kWh per kW per year, a system sized to cover 90% of use, $2.85/W installed plus $1,800 for permits and hookup, before any incentives, 3% yearly rate increases and 0.5% yearly panel wear. Your roof's pitch, shade and your utility's buy-back rules will change the real number.

How an install works
The people who measure your roof are the people who bolt the panels to it. Every crew is three installers and a licensed master electrician, all on our payroll.

Day 1
A 30-minute visit (or video call) to measure the roof, look at your panel and read your bills.
Day 3
Panel layout, itemized price, production estimate and payment options. Same price on day 3 or day 30.
Weeks 2–5
We file with the town and the utility and handle every inspection. You don't have to be home.
1–2 days
One crew, one or two days. After the utility's final sign-off we walk you through the app and flip it on.

“Our first bill after switch-on was $11. During the March ice storm we were the only house on the street with lights, and the battery still had 40% in the morning.”
“Three companies quoted. Brightline was the only one that came up on the roof instead of using a satellite photo, and they found a rotten section of decking the others missed. They fixed it at cost.”
“Electrician showed up at 8:00 like they said, ran 40 feet of conduit through a finished basement and you'd never know. Inspection passed first try.”
“Utility approval took a week longer than quoted, which wasn't their fault, but they called me every Friday with an update. System is beating the production estimate by about 6%.”
“Another company installed our panels and then went out of business. Brightline took over monitoring, spotted a dead microinverter, and replaced it under the manufacturer warranty.”
