Yes, the energy is stored for later use. The room has no sunlight. Having the LEDs would replace the conventional lighting already used in the room, and provide use to some excess power being generated(20W). I believe I need 200Wh, if I need them to be on for 10 hrs at a time? Is this correct? Wh = 20W *10hrs? I am unsure of the Voc though. If I connect the LEDs to the output, will I need to store the voltage in a battery, or charger first?
Sorry new to a lot of this stuff.
