I own store here in Minneapolis called âNeeds.â The sign of my store does not light up well in the night and I guess I need more LED lights for my sign board. But I am only looking for LEDs which I can power with solar panels. So I have query regarding this. What can I do to give solar power to LED lights? How many solar panels would I need? And also how much watt do you think 200 LED lights need? I would really appreciate your views regarding this. Thanks.
