WattHacker
For Enphase IQ Gateway & Envoy owners

Enlighten shows what your panels made. Not what they should have.

Your app is good at production. It has never told you what shade is costing you, which panels are quietly down on their neighbours, or why your true-up climbed. That gap is what we measure.

Works with the IQ Gateway and Envoy. 30-day money-back guarantee.

Four questions about your own roof.

You can answer the first one today. The other three are the ones that cost money.

What did my panels make?

Enlighten: Enlighten answers this well, per panel.

WattHacker: So do we — but that is not why you'd want us.

What SHOULD they have made?

Enlighten: Not answered.

WattHacker: Measured against a clear-sky model for your roof's own geometry.

What is shade costing me, and on which panels?

Enlighten: Not answered.

WattHacker: Measured monthly, by roof face and by panel, in dollars at your rate plan.

Are my panels degrading faster than they should?

Enlighten: Not answered.

WattHacker: Tracked year over year, as a record you can hand to an installer.

What silence costs.

Measured on real roofs. Yours will differ — that is rather the point.

How it works

  • The monitor arrives. Plug it into any USB port in the house.
  • It joins your wifi and finds your gateway. You paste one access token from Enphase — we walk you through it.
  • I set your system up personally, and email you when it goes live.

Not happy? 30 days, your whole first order back — monitor, shipping, and anything charged at checkout.
