GEN-I Sonce service

Our GEN-I Sonce service allows customers to take control of their energy supply costs by investing in a micro solar power plant and to save close to 75% on their electricity bill.

With its GEN-I Sonce service, GEN-I makes it easy for household and small business customers in Slovenia to make the decision to switch to the self-sufficient supply of electricity generated by the sun. GEN-I is thus the first energy supplier in the region to enter the self-sufficient energy supply market, and will facilitate the construction of micro solar power plants according to the “turnkey” principle for Slovenian customers.
