Technical FAQs 4

What happens if you push an electrical charge into a PV panel?

Pushing an electrical charge into a PV panel can damage the panel. Unfortunately, in certain Solar + Storage or PV repowering situations, this damaging result can occur.

How does a DC-coupled solar & storage system work?

The sun hits the solar panels which in turn push energy through conduit through an inverter. In a DC-coupled Solar + Storage system, where a battery is installed in front of the inverter along with the PV, power can flow either directly to the grid through the inverter or to the battery where it can be stored and later discharged to the grid.

Do all solar panels need a blocking diode?

Not all solar panel systems require a blocking diode. Here are situations where it is particularly useful: Off-Grid Solar Systems: In standalone systems where a battery is directly connected to a solar panel, a blocking diode is essential to prevent the battery from discharging into the panel at night.

How does a PV system work?

How to make sure power is always flowing where it should When operating a PV plant, the goal is to of course get as much solar energy onto the grid or the connected load. In a PV only installation, this is generally a straight forward process. The sun hits the solar panels which in turn push energy through conduit through an inverter.
