$0 Electricity Billsfor the next 7 Years

Forget the energy market, weather conditions and seasons. Our Smart
Controller guarantees you get no electricity bill for seven years.

How it works

Panels make the power. The Smart Controller makes sure you never buy any.

01

Roof check

Send your address. We read sun, shade and roof age from satellite imagery and call you with a straight answer.

02

One fixed quote

Panels, battery and the Smart Controller priced together. The number on the quote is the number on the invoice.

03

Install in two days

Our own licensed crew mounts, wires and inspects. No subcontractors on your roof.

04

Seven years at $0

The controller shifts your usage, charges the battery and sells surplus back. If a bill ever shows up, we pay it.

The Smart Controller

It buys when power is cheap, sells when it's dear, and runs your house in between.

The controller sits between your panels, your battery and the grid. All day it watches rates and weather. It fills the battery from the roof, tops it up from the grid only in the cheapest hour, and sells surplus back when prices spike.

  • Charges the battery before the evening price peak
  • Runs the whole house, including heat pump and EV charger
  • Keeps lights on through outages, switching over in 20 ms
  • App shows every kilowatt made, stored, used and sold

Why Lumen Roof

Solar that works on cloudy weeks, not just sunny ones.

Most systems only save money when the sun is out. Ours pairs panels with a home battery and a controller that watches rates all day, so the house runs on stored power when grid prices spike.

Questions

Straight answers before you call.

How can you guarantee a $0 bill?

We size the system to your last 12 months of usage plus a margin, and the controller does the rest. If a bill shows up in the seven years, we pay it. It is in the contract.

What if my roof is shaded?

We tell you on the first call. Some homes suit a ground array instead, and some are better off without solar. We would rather lose the job than sell a bad fit.

Does it work in an outage?

Yes. The battery takes over in 20 milliseconds, fast enough that clocks do not reset.

Who does the install?

Our own nine-person licensed crew. We pull the permits and meet the inspector ourselves.

Service area

Clarksville and about an hour around it.

Outside the list? Send your address anyway. We drive further for ground arrays.
