Coolest thing of the year: having lights, charging cell phones and laptops, and running radios just because the sun is shining!
The solar panels came in a kit: 3-15 watt panels, their frames, 2-LED lights, a charge controller, and 2 battery cables.
We bought it at Harbor Freight. With a coupon it was $195…the batteries were bought at Battery Joes (they are awesome-give them your business)…each was $85. Then long battery cables and other hardware was about $40. All told-call it $500 for a set up.
