    The 1000v on the back of the solar panel is 18 volt solar

    When manufacturers label photovoltaic panels as "18V," they're referring to the nominal voltage under standard test conditions (STC). 🔹 What It Means: This is the highest voltage (in volts, V) the panel can generate when no current is flowing (i., when it's not connected to anything). Example: A nominal 12V voltage solar panel has an open circuit voltage of 20. The result should give you P@MPP or power at the maximum power point, the same as the module's nameplate wattage. The VMP of a module generally works out to be. You can usually find this number on a label on the back of the solar panel. How many of this panel are you wiring in series?
