When designing a PV system, location is the starting point. The amount of solar access received by the photovoltaic modules is crucial to the financial feasibility of any PV system. Latitude is a primary factor. 2.1.2. Solar Irradiance
What happens if a PV system is not producing electricity?
If your system is generating more power than you are using, the excess will be exported into the energy utility grid, turning your meter backwards. During the times when the PV system isn’t producing electricity, such as at night, the power grid will supply all the building’s demand.
What happens if a grid-connected PV system exceeds a customer's load?
When the amount of energy generated by a grid- connected PV system exceeds the customer’s loads, excess energy is exported to the utility, turning the customer’s electric meter backward. Conversely, the customer can draw needed power from the utility when energy from the PV system is insufficient to power the building’s loads.
How does a grid-connected PV system work?
In a grid-connected PV system, the PV array is directly connected to the grid-connected inverter without a storage battery. If there is enough electricity flowing in from your PV system, no electricity will flow in from the utility company.
