average monthly bill

Sized to your bill

We size from twelve months of real usage, not a rule of thumb, so you do not overpay for panels you will not use.

Backup that actually works

Batteries switch over in under a second and keep essentials running through outages and winter storms.

One team, 25 years

Our own crews install, our own techs service. Panels, inverters and workmanship are covered for 25 years.

The full process
  1. 01

    Free home assessment

    A design specialist reviews your roof with satellite imagery and your last 12 bills, then confirms on-site if needed. No pressure, no pushy follow-up.

  2. 02

    Design and fixed quote

    You get a 3D layout, expected output by month, and one fixed price. What we quote is what you pay, including permit fees and any panel upgrade.

  3. 03

    Permits and utility approval

    We file the building permit, HOA notice and interconnection application. Most Portland-area jobs clear in 2-4 weeks.

We chose the battery after the ice storm. Last winter we kept the freezer and heat pump running for 30 hours.

Good questions

It converts your monthly bill into annual kilowatt-hours at $0.17 per kWh, sizes an array to cover about 95 percent of that, and limits it to what your roof can hold at roughly 55 sq ft per kW. Output per kW depends on sun exposure. Your written quote replaces these estimates with a design specific to your roof.

Your roof is already getting paid in sunlight. Let's collect.
