November 5, 20214 yr I would like to convert my existing outdoor security spotlights (10w and 20w) to work independently off solar power. Is this feasible? If so, how do I go about calculating what I would need to convert these spotlights? Ideally, I would like to connect them to one circuit, or together, as opposed to individually.
November 5, 20214 yr I guess it could be possible, i just went to the hardware store and bought a little solar light that i mounted on my wall. I think that will cost you a lot less than trying to convert your existing lights. 30 Watts continuous for 8 hours = 240Wh of battery storage. (You can probably find outdoor solar lights cheaper than the battery alone)(also remember to double the battery capacity if you are using lead acid) 100W solar panel + 12Volt DC charger. + A way to turn the lights on and off. + If the lights are AC you will need an inverter which for something this small will be quite uneconomical.
