Should I use my solar inverter reading or the net meter for Scope 2?
Use the net meter's import register for Scope 2: that is grid electricity you bought. Solar you used yourself equals generation, from the inverter or generation meter, minus units exported. Never subtract the inverter reading from the grid bill.
Three numbers
- Grid import, from the import register: Scope 2.
- Export, from the export register.
- Generation, from the generation meter or inverter.
Self use
Self used solar = generation minus export. Report it as renewable energy used, with no grid emissions.
What Senseible does here
Senseible reads electricity bills, including kVAh, demand and solar export lines, into dated records with the units, factor and year behind every Scope 2 figure.
