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
Reduce your operating costs

Core messages
PV for industrial self-consumption: generate solar energy where it is
consumed
This means maximum cost efficiency and protection of resources
Decentralized generation is the key to the energy supply of the future
Thank you for your attention.
