Tommelein promised for the end of 2018, with the launch of large-scale zonnedeel projects. Anyone with solar panels in its energy consumption wants to express, but in an apartment building, live or do not have a suitable roof, you can zonnedelen yet to invest in a installation at government buildings, fabriekspanden or sporting facilities, like swimming pools. But the system is still nowhere in Flanders rolled out.
As in Kortrijk, zonnedeelproject on stadsgebouwen funded by a system of crowdlending. Investors receive a financial return in the form of a fixed percentage. That yield, 2 to 4 percent, is a lot lower than the benefit that home owners out of their solar panels.
A payback period of 7 to 10 years now translates into a yield of more than 10 percent. That is three times higher than the efficiency of the existing zonnedeelsystemen. But zonnedelen with the energy yield calculated on the invoice, it would be for a family with an average consumption are more productive, even if a small rent is paid to the owner of the load-bearing roof. That is even more so if the trend of rising energy prices is to continue.
