Solar power for LED outside lights?

[Andrewnorman]

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

I have a solar motion sensor spotlight.
Light sensor automatically charges in the day time and automatically light at night. PIR sensor automatically light when people walk by. It can be used to avoid theft. The battery is 3.7V 2000mAH Li-on 18650, and the Solar panel is 6.0V/1.2W. Not sure if your friend is looking for this kind of light.
