Polycrystalline 5W 12V Solar Panel

altE solar panels are made ideally for use in OFF THE GRID applications. A 5 watt solar panel is about as small as they get. It's really good if you want to get your toes wet with solar. Take it camping, or power some small DC lights or fans. It's also a great panel for schools and students - in teaching them what solar is all about. These solar panels are super lightweight (under 2 pounds!) and portable, so you can take them anywhere too - which is great, because the sun is everywhere! Additionally, these panels are manufactured in accordance to ISO9001 standards and certified by IEC and CSA/US to assure electrical safety compliance.

Solar is so cool- what's better than using the most abundant natural resource to power our lives? It makes so much sense! And it's FREE ELECTRICITY! Once you get the bug, and start small with this solar panel, you'll be aching to go bigger and better. This 5 watt solar panel consists of 36 polycrystalline solar cells, and can operate in temperatures as low as 49 degrees below zero and as high as 185 degrees Fahrenheit - those are some extreme temperatures! And with the sturdy aluminum frame, and 3.2mm tempered glass, the durability of this module allows for long term usage and worry-free off-grid living.

Please be sure to watch our videos to the right - they contain really great information on how to wire solar panels, the best orientation, and a full off-grid solar system demonstation, as well. altE is the best place to start learning how solar energy works, and the numerous advantages of solar energy. We're here to help you make renewable do-able!
