    It’s Great Hobby At Low Cost Plus It’s Also For Education Project And Take It With You I bought it to try it out, DC House also got sale through me, Al; owner of home solar installer, had bought 25 watt solar panel. Through my Amp Meter, it produce nearly 1/3 higher reading than Harbor Freights 15 watt $65 solar panel, without charging controller, is more than twice of size and weight than this small 20 watt solar panel (Around 5 pounds). Made with real Aluminium frame and Glass, not plastic. All of DC wiring from panel to battery clamps is 16 Gauge, is more than enough for 20…

    So far, so good The panel itself is well built and putting out enough power to charge a 50 A/h deep cycle battery between camping trips. Granted that I never entirely discharge it, but it’s good that I don’t have to carry a battery up the mountain and back after every few trips to take it home to charge it like we used to have to do.The actual rating on the sticker on the panel says 25 watts, not the 20 watts as in the item description. The charge controller is questionable quality though…
