>>14164920* Total cost of the system would be <$20million dollars.
But really you could increase the solar panel to match the battery capacity. Battery capacity is also way too much, but it can likely last 50+ years easily since they're LFP batteries and each can get ~1000-2000+ cycles.
Lets say we double the solar panels to quadruple the solar panels to 480 KW, that will give us a cost of $800K for solar panels. $14.4 million for transport.
Now we have a ~$15 M for 480 KW solar panels and ~$15 M for 15.4 MWh battery energy for ~$15M. A nice total even number of $30 million.
It should provide power to more than 100+ homes very easily and last well into 50+ years.
