I use solar to power a small hunting shack; lights, security camera, monitor, fans and sometimes a small TV. I have always used Rich products from the beginning and have had great success with them. I started with a 100 watt panel that has served me well for the last 6 years. I upgraded to a 220 watt panel (seen in the photos) recently and really like it. Sometimes I stay at the shack on consecutive nights, staying 9 nights recently, where I had cloudy and less than ideal sun light during the day. The larger panel is working out just fine and charges the 100 amp AGM battery in short order. I use the Rich MPPT 20 amp charger.
