If you used 100 kwh of energy but generated 60 of those with your solar system the net meter will show 40.

In order to participate in net metering you will only need to add one additional piece of equipment to a standard grid tied solar panel system a bi directional meter.
Simply touch the solar panel leads with the multi meter probes matching their corresponding polarity red to red black to black.
Consult your solar panel s documentation for information or contact our technical support desk.
Measure at higher volts than what your panel is approved for.
Make sure that you are measuring at the suitable voltage level for a solar panel.
Doing this will give you the confidence and assurance that your readings will be accurate.
The second shows power coming in from the grid and the third shows power going out from your solar into the grid.
Bi directional meters have three display screens.
For example if your panel has approval for 30 volts set the multimeter to have a higher reading.
Open circuit voltage can vary depending on your solar panel but the readings we are usually looking for are in the range of 15 to 23v.
Some exceptions may apply based on panel type.
