How to Add a Portable Solar Cell System to Your RV
For a 200-watt system, a 20-amp controller would be more than sufficient (one 100-watt solar cell generates under six amps). But we chose the higher amp rating so we could add additional solar cells in the future. A MPPT charge controller can be twice the price of a PWM charge controller, and both function well in a solar cell system.
