The problem is with a 200 A panel you can only feed a maximum of 40A from solar into any one 200A panel (This is the 120% rule) meaning that the total of all feeds cannot be more than 120% of the rating of the buss bars in the panel. 20% of 200A = 40A
Therefore, with these series-connected solar panels, we now have a solar string with the following specifications: Rated Power = 100 Watts + 100 Watts = 200 Watts; Max. Power Current = 5.62 Amps; Max. Power Voltage = 17.8 Volts + 17.8 Volts = 35.6 Volts; Short Circuit Current = 6.23 Amps;
How does shading affect solar panels in parallel? Shading affects the current (A) of the solar panel. The voltage (V) is affected by temperature. Do solar panels charge faster in series or parallel? This is a tricky question. Generally, batteries get charged quicker in series because of low light in the early morning and late evening.
