Solar PV panels collect the sun’s energy and convert it into direct current (DC) electricity. An inverter converts the DC electricity from the panels into alternating current (AC) electricity, the type of electricity we all use at home. This electricity can be used for any application and will cost you nothing.
When the solar panels are generating more electricity than your house needs, the excess electricity is stored inside batteries. The electricity stored inside the batteries can be used at times when there is no sunlight. When the batteries are full, excess energy is exported onto the main power grid.
When there is sunlight, but the solar panels are not generating enough energy, electricity from the batteries will be used. When the batteries are depleted, the system will take electricity from the main power grid.
The advantage of a hybrid system is that when the batteries are almost depleted, the system can charge the batteries with electricity from the main power grid. This charging will be done at night, when electricity only costs you the night-tariff.
Below, will we give you an overview of the materials used in a hybrid solar panel system.
