When solar power can control the energy input into buildings
More and more buildings are being constructed with a built-in, stand-alone solar unit which completely runs the building's energy policy. The electricity storage function therefore becomes crucial.
It must be able to:
- relieve the electrical grid during peak hours
- ensure constant current quality
- provide an emergency back-up in a power cut
- introduce flexibility in the energy management
When the sun powers each isolated house
Two possible strategies
Two strategies are possible for isolated rural areas:
- the solar unit combined with a diesel generator for the entire village: it acts as a stand-alone mini-grid,
- a stand-alone installation installed in each house.
A key point of these stand-alone installations is how to store the energy
During the day, the solar panels produce energy, stored immediately in a battery. An inverter operates constantly and provides electric power to meet instantaneous demand.
Greater demand at night
More electricity is consumed when night falls and lights are switched on. The generated electricity stored is then used thanks to a clock signal which backs up the system.
