While I agree for the price of solar
these days this unit is high for the watts you get & also agree more watts is better but when solar
was still a pretty pricey option I had a 15 watt panel that served me well for a number of years. If it was nice and sunny out and no tree coverage to worry about it would keep my battery topped up each day while dry camping
- but all it had to recharge up though was the power usage of the Fantastic Fan (used sparingly), water pump and lights
all LED, also used sparingly.
