In the real world, on average, a 50-watt solar panel will produce about 200 watts of DC power output or 16 amps @ 12 volts per day. Considering 5 hours of peak sunlight.

A quick rule is to divide watts by 10 for 12V systems or 20 for 24V systems. For more accuracy, divide the load by the actual battery voltage and adjust for inverter efficiency (typically 85%).
