EEG feed-in tariff, self-consumption rules (Eigenverbrauch), and facility-type-specific regulations for residential and commercial solar in Germany.
Every market, every tariff, built in
Net metering, net billing, time-of-use, tiered, and demand charges all live in the tariff configurator. Tune currency, seasons, export rates, and VAT, or build a brand-new tariff structure when a market changes the rules. Pre-built for the US, UK, Germany, South Africa, Türkiye, and Austria, and extensible to any market via the tariff configurator.

EEG feed-in tariff
Fixed-rate feed-in payments for exported solar electricity under the Erneuerbare-Energien-Gesetz. Rates depend on system size and commissioning date.
Self-consumption (Eigenverbrauch)
Self-consumed solar electricity reduces grid purchases. solarVis models the financial benefit against local retail tariffs.
VAT treatment
Since January 2023, residential PV systems under 30 kWp benefit from zero-percent VAT on purchase and installation.
EEG surcharge
The EEG surcharge for self-consumption has been removed for systems under 30 kWp. solarVis applies the correct rules per system size.
01Does solarVis track the current EEG feed-in tariff?+
Yes. Rates are updated when the German Bundesnetzagentur publishes new degression values.
02How does zero-VAT work for residential solar?+
For systems under 30 kWp, solarVis applies zero-percent VAT automatically based on facility type and system size.
03Can I model self-consumption vs full export?+
Yes. solarVis calculates both scenarios and lets you compare ROI, payback, and NPV side by side.
