The costs for your own system depend on the size - we are happy to provide you with an individual quote. In order to benefit from all the advantages of green energy with PV, you do not have to purchase and operate your own system, as you also unlock these benefits when renting a system - in this case, ENVIRIA bears the full investment risk. At the end of the contract term (approx. 20 years), you can take over the system for a reasonable price.
