One other thing to remember is that there are now mini-split AC/Heatpumps that run directly on solar panels. This allows the DIY person to use LOTS of solar directly without having to have a grid/tie net meter.
Since many modern mini-split units now have variable speed compressors, this means internally they run on DC, and that then makes a perfect marriage to solar.
