Do You Need a Regulator For a Solar Panel? (Here''s When)

Do solar panels have built-in regulators? Sometimes a solar panel will come equipped with a basic regulator affixed to the back, but this is often a feature on cheaper solar panel models only. Most professionals prefer to install a separate solar charge regulator so that the current can be more closely and accurately monitored.
