solar power for LED outside lights?
My friend owns a store here in Minneapolis called The Green Goober.
Her sign does not light up at night very well, and she needs more light... Shes looking to put up LED lights and solar panels strictly to power them.
Does anyone know where to find such a think/how much wattage LED lights need?
Any help is greatly appreciated
Of course, night lights can only be powered by solar by having batteries to hold the power from day to night. Practically, that means using standard 12 volt panels with a charging regulator. The solar panel is rated in watts, but the amount of sun in Minneapolis in winter is rather low, so a store selling them is going to have to provide data on output there. The nights are long, which means more batteries for storage and more charging each day. LED floods and area lights are not that common, so no real answer is possible - unless she plans on outlining the sign parts with individual LED's Power of those can range from a few watts way, way, down.
