Lots of people! Including my ex hubby. We run our motor home almost exclusively on solar power.
what do you need it for? how much power ? That will determine what you need/how to construct the solar power,if you can use small panels,need to piggy back the multiple panels,need storage for the power/how much?do you need the system transportable or stationary?do you have access to full sun all the time? this will matter too on storage of power.
Solar panel for what?
