Purpose of the site

The site estimates the yield of plug-in solar devices and PV systems with PVGIS radiation data (European Commission), self-consumption with metered household profiles from HTW Berlin, and the feed-in tariff according to the Federal Network Agency's publications. It is not an offer from a grid operator, energy supplier, retailer or installer, not energy, tax or legal advice and not a public authority. Calculation steps are under How we calculate.

Liability

Values are checked automatically before every release and reconciled whenever a source changes; we give no guarantee for the yield of a specific system. Linked third-party sites are the responsibility of their operators. Please report errors via the contact page.

Embedding

The plug-in solar and rooftop PV calculators may be embedded free of charge by iframe as long as the source link stays visible: Embed a calculator.

Consumer dispute resolution

We are neither willing nor obliged to take part in dispute resolution before a consumer arbitration board. On data protection: privacy policy and cookies. As of: 2026-10-15.
