40 Watt Black Frame Mono-crystalline Solar Panel and Battery Charger
This is the cheapest mono-crystal panel I’ve found, and it works as expected. However, remember (or learn) that when the sun shines full, you will generate the most power….. on a cloudy (or not full sun day) you will generate very little. If you have alot of full sun, go for monocrystal (ages slowest). However, if you have shady area or often cloudy, go for amorphous (ages faster). I have both types and so generate power every day. Monocrystal panels generate more per square inch so basically take LESS space to do the job. This panel is a good investment.
