We have had Sunpower solar panels since the end of 2018, fully paid off, and they pretty much cover our usage all year. We have 1:1 net metering, and it does not expire, so we try to bank as much as we can all year to use in the winter, as we are a fully electric house (Geothermal ac/heat, mini split in the basement, heat pump hot water heater).

Due to having 1:1 net metering, is there any actual benefit to a battery system? As far as power outages, while we are definitely getting more lately then we have in the past, I'm not sure how much of that is just due to tree's falling, or poles falling, etc. We are in NY.

Thanks for any help! Budget is a major concern, and It's a tough pill to swallow to spend a lot on a battery system if it doesn't make sense for us.
