The German government is planning to ease the rules for connecting solar photovoltaic (PV) installations on the roofs of commercial buildings and remove system certification requirements which have hampered the deployment of solar panels on company roofs.
The draft regulations, presented by the Ministry for Economic Affairs and Climate Action (BMWK), apply to solar systems with a capacity in the range of 135 kW to 500 kW and follow a months-long consultation process in which the Federal Network Agency and network operators were closely involved.
Under the proposed regulations, solar installations in this category will in future be exempt from the system certificate obligation if they feed up to 270 kW of power into the grid in addition to the self-consumption.
Industry association BSW Solar, which took part in the consultation process, welcomed the proposal and expressed hope that the changes will be quickly incorporated into the Electrotechnical Properties Verification Ordinance (NELEV) and a new Technical Requirements Ordinance (TAV).
According to BSW, the compromise that has been reached will lead to an increase in photovoltaic installations on commercial roofs in Germany. In recent years, the strict certification requirements had severely slowed down the expansion in this segment and led to a months-long implementation backlog. The market segment is considered to be particularly critical for the achievement of Germany’s green energy targets. The country aims to have 215 GW of solar installed by 2030 compared to around 70 GW currently.
