Residential solar may still make sense for new construction (maybe?) in the right areas. But there was a lot of scammy behavior around home solar installation at one point. Given that home solar does not effectively give you a backup generator for free (barring a lot of batteries and specific electrical hookups as I recall), it's not clear it's a big win in general. A lot of utility things aren't ideal at the individual house level if there's an option.
A lot of home solar installers now include grid tied batteries as part of a standard installation, which is what NEM 3 was intended to do (secondarily, after its primary goal of giving CA IOUs a massive free lunch).
