Most of those photovoltaic panels are perfectly horizontal. While that would be a sensible angle in .Quito, Ecuador; methinks, an installation in northern New Hampshire would prefer a 40 degree incline toward the south.
Of course, if your whole life is spent ticking off boxes on applications for govrnment subsidies, then I suppose you don’t have time for details.
How many of those panels and batteries would be required to power my heat pump air conditioner at home down south?
