Hybrid Photovoltaic plant gives you the possibility to store energy when the production exceeds the consumption in batteries in order to be available when needed, often after sunset.
Those systems are preferred by family houses, retail shops, warehouses, country houses or places where the public power supply is bad or missing.
Depends on your lifestyle, daily rhythm, way of heating your home, you can easily reach 70 - 80 percent self-sufficiency by building small photovoltaic plant. If there is need you can reach 100% self – sufficiency by adding more batteries.
