The duration and administrative burden of the procedure for connecting a solar PV system to the respective electricity distribution company (EDC) depends mainly on the purpose of the produced energy. For on-grid systems up to 30kW, where the energy will be used for own consumption, the procedure is the shortest and easiest. It is usually about 4-5 months depending on the requirements of the specific EDC. If the produced energy is intended for sale at a tariff, the process is extended by 1-2 months. This is due to the need for an additional step upon request for a Power Purchase Agreement.
The tariffs for energy from solar PV power plants, which are determined by the EWRC by July 1 of each calendar year, are divided into two categories: up to 5kW inclusive, installed on roofs and facades, and from 5 to 30kW inclusive, installed on roofs, facades and land.
There are no special preferences for roof power plants up to 10kW either in terms of purchase price or in terms of the administrative process. There was only discussion of such relief, but no action was taken with regards to legal changes.
