Hannover – A small garden needs a lot of sun for the plants and for the soul. In Hanover, however, the sun will soon also be needed to generate electricity.
Because soon it will be allowed to install photovoltaic systems on the leafy roofs and to produce electricity for personal use. So far, solar panels on the roofs can be a maximum of one square meter.
Andreas Pieper, Vice President of the District Association of Allotment Gardeners, shows the battery of the edger. It could soon be charged with solar power
So-called balcony power plants with an output of up to 600 watts are then permitted. The square meter restriction is to be dropped with the change in the allotment garden regulations. A vote on this is expected to take place at the general meeting of the district association of Hanover allotment gardeners in September.
“For a solar system, you then need a building application and a structural analysis of the arbor,” explains the association’s vice president, Andreas Pieper. Not every building can bear the load. The allotment gardeners want to win the municipal energy service provider enercity as a partner.
Whether lawn mower, water pump, tools, shredder or refrigerator – with your own green electricity you can also save costs. “For me, that would be around 200 euros a year,” calculates Pieper. However, it may only be produced for personal use without making a profit.
An exception could be the clubhouses, which may also be allowed to feed their solar energy into the local power grid.
The Hanover district association of allotment gardeners includes 97 associations with 270 colonies and 19,400 plots
But the project is worthwhile above all for the climate. With 19,400 plots in 270 colonies, Hanover has one of the highest allotment garden densities in Germany. Arithmetically, a maximum of 7.7 million kilowatt hours (7760 megawatt hours) of electricity could be generated per year.
With an area of 1000 hectares, the allotment gardens make up around 5 percent of the entire city area.
