I don't know your exact rates in NJ, but in NY the natural gas prices vs electricity are so low that it is not worth it from a cost standpoint to use heat pumps and electric water heaters.. It is also very likely that your system will produce more than the rated amount. For example I have a 11,050 kwh system and it produced 14,940 kwh last year - I am in southern NY.Using the estimated output and best-guesstimates for my Mach E usage post-pandemic, I'm probably still going to buy about 600 kwh a year from PSE&G if everything else stays the same. Without adding the extra 4500kwh cushion for the Mach E I'd end up buying about 5000kwh from them.
Even if my solar produces more than I use, I'd like to switch my hot water heater from gas to electric and augment my gas furnace with electric spaceheaters in the winter.
