120 Watt Solar Panel
How can I find a conbination of Solar Powered Street Light and Security Camera as a combo and at what Price?
I am working on a project that will supply Solar powered Street Light to a State in which Security Cameras will also be installed at select points on certain poles. I want to know what this will cost with the following requirements for the Street Light: 40 watts LED for the light source and 80-120 watts for the panel with battery and controller all inclusive.
A forty watt street light isn’t much of a light, even if it uses LED’s — which at present are about as efficient as a high pressure sodium lamp. Solar Power runs about $10 a watt; you need 40 watts for the light, plus 120 x 2 = 240 watts for the camera (presuming that it operates continuously), which you have to double because of the cosine rule (sun doesn’t shine directly on the panel, so average power is half of peak) for a total of 560 watts Solar Cell capacity. That’s $5600 — assuming that it doesn’t rain.
