Writers haven't a clue. Below are two points out of many to consider.
Solar without Battery backup:
-> No power when lines are down.
-> Repairs take much longer as the line tech need to shutoff each house with solar prior to work.
-> The more houses connected this way the more spikes on the grid (non sunny days, nights)
---> To avoid spikes electric co's have been known to throttle power back to the lines (google: electric co's requiring windmill throttling)
Solar WITH battery backup:
-> Needs to be properly ventilated as the batteries give off toxic fumes.
-> Shouldn't be in a basement due to the first point as well as flooding considerations.
-> What to do with more toxic waste.
