Hi guys,
First off this is a great forum, I finally signed up to ask a couple questions:
I am buying a new construction home, which already has solar panels for a total of 6.74kwh but they aren't the best or most efficient ones only around 18.7%. they do have some space left to add panels. There is no battery, and they're directly tied into the grid.
The builder did this to avoid cost of getting gas line extended to the house so there is no gas.
Questions: we do have time of use discounts. What's the best way add more capacity to the system? Use same panels or use different panels?
They used APsystems yc600 microinverter. Is this good? Should I change it out?
Reading the forum it seems battery isn't there greatest cost savings, but should I still get something like harbor smart? Any downsides? Mainly for outages
How do I know I will automatically switch to grid when needed? If I do get batteries can I get an installation that grid and pv only charge the batteries and I use the electricity from the battery (or is it not efficient due to RTE loss?)
Because of the gas issue, water heater, heating, cooling , cooking is all electric. The estimators aren't great at telling me what's the right system size without sending out quote requests, which I don't want to go.
Is there any program to trade up pvs to better ones? Is it worth it?
