About Rooftop solar plants?

In a 5KW rooftop power plant, if there is a loss of 6 volts then how much loss in units generation it may incur? Seeking answer from knowledgeable electrical engineers working in solar plants.

    That depends on the system voltage!

    That could be anything from 30V to near 600V, depending on the system configuration.

    The loss is proportional to the ratio of system voltage to the 6V loss.

    At 30V, 5000W = 167A.

    6V loss would be 6 / 30 = 0.2, * 5000 = 1000W loss

    At 600V, 5000W = 8.3A.

    6V loss would be 6 / 6000 = 0.01, * 5000 = 50W loss.
