Energy production can be measured one of two ways:
- Lifetime Meter Reading: the cumulative reading of the solar system’s production (typically displayed on a physical solar meter). This measure will only increase from one month through each subsequent month.
- Monthly Net: the generation produced by the system in an individual month (this tracking method is primarily used by remote monitoring platforms). This measure may appear to fluctuate from one month to the next according to seasonal climate cycles.
Customers are strongly encouraged to stick with one type of reading when self-reporting. Whichever method is used, however, solar production should always be reported in kilowatt-hour (kWh) units for SREC purposes.
TIP Some solar meters – such as the LGate 120 meters from Locus Energy – may display the lifetime reading as a "Net" reading, which only increases from one month to the next. Please do not confuse this for a monthly net.
