What would be the minimum battery or possibly even a large capacitor to make this setup work? 300 Watt (3pcs 100 Watt, 12 Volt) Solar Panel Kit with LCD PWM Solar Charge Controller for RV's, Boats and Off-Grid I 'm basically looking to create a "light pipe" from the rear of my house to front using solar panels to run LED grow lights in the front.. So no storage is needed, just supply 12v to lights when there is sun, shut off when there isn't.. lights I will be using are 2 (possibly 3) 60w strings.. Really just need to stabilize the output voltage..
