After saw another post about battery degradation, and also about 80% efficiancy for the electricity need to charge PW and how much you have got when output DC.
This is only for the region do not have time based electrical charge and net metering in place.
It seems to me that backup-only option can be more cost effective. Am I right?
my reasoning (maybe im wrong, but would like to hear what other ppl thought)
1. we have net metering, so the extra kwh put back, you can have exact amount back to use. (no loss for PW to AC)
2. PW battery degradation can be far less since there is no need to cycle at night.
3. your additional backup juice can stay year round for additional backup power. you can set something like 80% to avoid damage the battery.
