Polycrystalline 30W 12V Solar Panel

altE solar panels were developed for use in OFF THE GRID applications. In other words, getting electricity from a natural resource, versus the electric company. A 30 watt solar panel can be useful in keeping a deep cycle battery charged (a 'trickle charge') , so you can then have power after dark, or when the grid goes down. Check out this Emergency Preparedness Kit that we put together to help you with just that! Or, how about setting one up in the shop to help supplement your power tools? Every little bit helps. These solar panels are lightweight (only 7 pounds!) and portable, so you can take them on the road with you too to power your portable electronics like cell phones, games etc. Additionally, they are manufactured in accordance to ISO9001 standards and certified by IEC and CSA/US to assure electrical safety compliance.

FREE ELECTRICITY from the most abundant natural resource is one of the biggest advantages of solar energy. Telling all your friends that you are dabbling in off grid living increases your cool factor exponentially. It will be contagious too! Once you start small with this solar panel, you'll be looking around the house or cabin to see what else you can power. This 30 watt solar panel consists of 36 polycrystalline solar cells, and can work in temperatures as low as 49 degrees below zero and as high as 185 degrees Fahrenheit - a wide range gives you flexibility in any environment. 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.

We've put together some very helpful videos to the right to get you started - how solar energy works, how to wire solar panels, the best orientation, and off-grid solar system demonstations. altE is the best place to start learning about the many advantages of solar energy. We're here to help you make renewable do-able!
