TL;DR
The RU is the Swiss federal grant managed by Pronovo. The amount depends on the scale and configuration; use the official tariff calculator before integrating it into the budget. It is distinct from the feed-in rate.

Financed by the network supplement and managed by Pronovo SA. The calculation combines the parameters published by Pronovo, the installed power and possible correction factors. Typical small installation procedure: commissioning -> installation report -> mysolar.ch file -> validation and payment according to Pronovo schedule.
The RU represents 16–22% of the gross cost of a residential installation. Scale and procedure to be checked at the time of the quote. Accumulation possible only with truly confirmed cantonal or municipal aid.

The RU is registered in the LEne. Any removal requires legislative amendment. Approved facilities are protected. The program is regularly renewed.
