Prof. Dipl.-Ing. M.Sc. Econ. Manfred Hegger, gave a lecture on 26 November 2014 at the 6th North German Passive House Conference in Neumünster on the topic "Aktivplus im Blick: Guiding Thoughts - Implementation - Perspectives".
Düsseldorf. 4.25 terawatts (TWh)! This is how much electricity was produced last year (2017) by the photovoltaic systems installed in North Rhine-Westphalia. This corresponds to the average annual electricity demand of more than 1 million four-person households. In total, there are 8.7 million households in NRW.
At the end of last year, PV systems with a total of around 4.64 megawatt peak (MWpeak) were installed in NRW. Compared to the previous year, this represents an increase of more than 3.5 percent. This means that around 136 kWpeak are installed per square kilometre of state surface in NRW. According to data from the North Rhine-Westphalia State Office for Nature, Environment and Consumer Protection (LANUV), there is an average irradiation of 916 kWh per kWpeak per year in the most populous state in Germany. "Photovoltaics has established itself as an attractive option for energy generation due to the technical developments of recent years. The combination of PV with storage technology is also increasingly interesting as a solution for own power consumption in private and industrial applications", says Carl Georg Graf von Buquoy of EnergyAgency.NRW.
Although the construction of PV systems in Germany has been declining in recent years, the construction of solar systems and solar power production have been increasing again for the past two years. The share of electricity generation in Germany from renewable energies was around 38 percent in 2017, with photovoltaics accounting for 7.2 percent nationwide and 2.6 percent in NRW. The PV systems installed in Germany produced a total of around 40 billion kilowatt hours of electricity, thus mathematically covering the annual electricity requirements of over 10.5 million households. With the PV capacity of around 4,640 MWpeak installed in North Rhine-Westphalia in 2017, the state ranked third in a Germany-wide comparison behind Bavaria and Baden-Württemberg.

In the Bavarian 10,000 Houses Program, there is now also money for electricity storage units if the user installs them together with a PV system. Until the end of 2020, 24 million euros are available for the entire program.
The Bavarian Ministry of Economic Affairs has launched the new photovoltaic storage programme. It is part of the well-known 10,000 Homes Programme. From 1 August, owners of detached and semi-detached houses can apply for funding for a new electricity storage unit in conjunction with a photovoltaic system. In addition, there is the possibility for a grant for the installation of a private charging station for electric vehicles.
"We need to make better use of the sun's potential," says Minister of Economics Hubert Aiwanger. " With the new support programme, we will give additional momentum to the energy transition. It sets the right incentives to advance the decentralised expansion of renewable energies in Bavaria and will actively involve citizens in the energy transition." Citizens can also reduce their electricity costs with the help of the programme. The smart controls and connections provided for under the funding will also enable plant operators to participate in regional direct electricity marketing in the future.
The subsidy amount is graduated according to the capacity of the battery storage unit and ranges from 500 euros for a three-kilowatt-hour storage unit to 3,200 euros for a 30-kilowatt-hour storage unit. The prerequisite, however, is that the applicant simultaneously installs a new photovoltaic system whose output in kilowatt-peak is at least equal to the value of the capacity of the battery storage unit. For an additional charging station for electric vehicles, the subsidy is 200 euros. The Ministry of Economics is providing up to 24 million euros for the 10,000 Houses Programme until the end of 2020.
The successful EnergySystemHouse programme component will be continued. There, too, the use of solar energy and its storage in combination with energy-efficient refurbishment or particularly efficient houses and systems will be promoted. "The targeted promotion of innovative technologies is working, manufacturers are developing new systems and bringing them to market," says Aiwanger. "The number of particularly efficient heat pumps on the market has increased from 40 models to over 160 models. In the case of high-efficiency heat storage systems, the eligible models have increased fivefold to more than 250 models in the same period. Energy advisors report that many building owners are improving their plans and constructing or refurbishing buildings much more efficiently because of the programme."
All subsidies of the 10,000 Houses Programme are coordinated with the federal programmes and can be combined. It is very easy to apply electronically. Further information and the application platform can be found under this link.
