Terms of use

The basic terms and limits for Wattlyze calculators and their official data-backed estimates.

Estimates only

Wattlyze provides educational estimates. Actual costs depend on tariff, usage, building, weather, installation, incentives and provider terms.

Calculator output is not financial, legal, engineering, tax or installation advice. Verify decisions with qualified providers.

Official datasets can change after a page is published. Every result shows a source and data date so you can judge how current it is.
