The PV array includes four PV modules that are coupled in series. Figure 4 depicts the results of a series connection of four modules, each of which is exposed to …
Sign: A voltage number that is higher or lower than expected. Cause: Too many modules wired together in series will result in a Voc number that is too high. Too few modules wired in series will result in a Voc number that is too low. Remember to add the Voc values together for as many modules as you have wired in series (see ohm''s power law)!
