In order for Berlin to be able to achieve the self-imposed targets for expansion of photovoltaics (PC), great efforts still have to be made. The current instruments are not sufficient for this. In order to make use of the great potential of apartment buildings, there is the possibility of producing PV electricity on their roofs and selling it directly to the tenants. But the so-called "tenant electricity" has so far led a niche existence.
At the same time, tenant electricity offers enormous innovation potential on the consumption side and could be an element for a flexible and sustainable electricity system. It is also an important instrument for tenants' participation in the energy transition.
However, some obstacles are delaying the expansion of tenant electricity. The revised regulations in the federal government's "Easter package" for the expansion of renewable energies do little to change this. For tenant electricity projects to be successful, they must be easier to implement and economical to operate.
