These are normally $189.00 for three 15-watt panels plus all of the control gear. You still have to provide your own deep-cycle car or boat battery. This week Harbor Freight has them on sale for $139.00, plus there is a 20% off coupon in many of the handy-man and hunting periodicals. Depending on how many sets you sequence together you can run lights, fans, a small dorm room size refrigerator, radios, and charge batteries. These sets are not going to take you off of the grid, but they can be a valuable asset during extended power outages. I was very surprised at the positive reviews and some of the elaborate setups in the videos below.
