Sustainability
Every locally-used solar kWh counts. Habiwatt makes them count.
The cheapest, cleanest kilowatt-hour is the one your roof produced and your home actually used. Habiwatt shifts flexible demand into your solar surplus and the grid's cleanest hours — and reports the result without greenwash.

Honesty policy
Estimates are labelled estimates
Every sustainability claim in Habiwatt has a defined methodology: weather-normalised baselines, stated confidence levels, and ranges instead of fake precision. And when extra hardware wouldn't pay back — a bigger battery, more panels — Habiwatt recommends not buying it. Trust is worth more than affiliate revenue.
Europe
Built for the European energy transition
Dynamic tariffs, grid congestion signals, carbon intensity, energy communities, renovation guidance: Habiwatt is designed around the flexible, low-carbon buildings Europe is moving toward — one home at a time.
