A solar panel system is simple.

Solar panels are installed on the flat or sloping roof. Suitable roofs are oriented south, east or west. (with the current prices of solar panels, east and west roofs are also excellent to use). Solar panels provide direct current.
The inverter turns the direct current from the panels into alternating current that can be used in a home installation.
The current from the inverter is used first in the house.
Power that is not used in the house itself is supplied back to the grid. Depending on the type of meter, the meter can run backward (analog meters) or runs a separate counter for return delivery (electronic meters).
If the meter is not suitable for return delivery, it can be replaced later. If there is a high power consumption is in the house, the flow of the solar panels is supplemented from the network.
