Solar in Puerto Rico

I saw a report that Puerto Rico is investing big in solar. Even before the hurricane there was some solar in action. This is a perfect time for Puerto Rico to make the next generation in power generation. Down with the grid. We no longer need a grid. Take a group of houses. Five to twelve houses wired together would be best. Setup each house so that three houses can supply enough energy for the whole set of houses using a minimum of power. A combination of solar and wind power. Using 100 watt solar panels and 500 watt smaller wind turbines. Using standard lithium batteries that look like car batteries instead of expensive house batteries. Using the least expensive, most available types of gear. This way people can build out as they have money. Each group of houses could have a backup diesel generator to handle any other major failures. Good luck to our island Americans.
