Improved nuclear or bust. Also, no one needs more than 12v to see in the dark at home.
For strictly home lighting a single 500 watt solar panel and a AGM deep cycle battery can run led lights for a week or more between a day of sunlight. While doing mission work in Latin America we installed a shallow well with DC pump run off a single panel during the day into a small water tower for the village. We also installed a single panel system with a AGM 12v deep.cycle in the church that runs led lights and a small fridge to keep.medication at storage temps in the church’s clinic. For a few hundred dollars you can have a off grid system that runs lights, a small fridge and a well pump drastically improving the quality of life in remote or impoverished area’s. Two panels is enough to bring a system up to running a electric slow cooker or hot plate inside eliminating burning run for wood inside to cook with. Slow cookers use 250 watts at first then cycle off and on to keep temp at 90C, a hot plate uses 800 in high. Two 500 watt solar panel in 8 hours of daylight make 8kWh more in the tropics where they get 12 hours of sun per day.
