I'm in California and expect to get PTO under NEM 2 soon (I'll celebrate it when I see it...). I have solar and battery, the TOU rates in the summer are $0.62 4-9pm, and $0.24 9-4pm. On an annual basis I expect to be buying a modest amount of energy, i.e., I don't expect a production surplus. Is it worth selling battery power during the peak time to get more credit?
Broadly speaking, I see four options:
It seems that for someone who is a net importer on an annual basis option 3 may be the best, while for someone who is a next exporter option may be the best? Assuming some reasonable daily discharge depth, I guess, to reduce battery wear?
Broadly speaking, I see four options:
- never sell battery power: benefit from less battery cycling
- use battery to maximize self-consumption, e.g. night-time use: benefit from avoiding NBC's (non-bypassable charges), i.e. $0.03/kWh ?
- use battery to maximize sell-credits, e.g., sell battery power down to minimum reserve state of charge by the end of peak rate, thereby having capacity the next day to soak up solar and sell again during peak time
