The solution – direct generation of solar power for self-consumption  Use of roofs or land for photovoltaic power plants  Direct use of solar energy for own demand  PV runs together with grid

 100% PV self-consumption or surplus PV electricity injected into grid (net-metering, feed-in tariff)

 Self-consumed solar electricity reduces energy bill  Commercial/ industrial energy demand takes place mainly at daytime  High correlation with solar energy profile
