With
the solar electric power exchange we support the market
introduction and the further development of photovoltaics.
Photovoltaic is the direct conversion of solar energy into
electric power by solar cell technology.
In
line with the principle of an electric power exchange the
cheapest plants are chosen and supported.
Bewag
gives an investment subsidy of up to 50% of the costs for
the plant (not more than 7.250 DM/kWp). In addition a cost
oriented price for solar power supplied into the electrical
grid is guaranteed over 15 years (not more than 0.81 DM/kWh).
This makes up for about 50% of the initial costs for the
system.
