How long does it take to charge a battery through a solar panel? Is that your question. too many unknowns. How big is the battery, how big is the solar panel, how direct is the sun that shines on the panel? We must start with the requirements of his power, then you can choose a solar panel provides about 3.4 times the capacity, then choose a set of batteries to provide power when the sun does not shine. Then choose a charge controller and an inverter. to supply a house can cost the U.S. $ 20k – 50k. .
