How does sunlight really make electricity, anyway?
Why is it important to have the solar panels pointing direclty at the sun?
If there is shade on the panels, how will that affect my production?

Polycrystalline 140W 12V Solar Panel
ALT140-12P
altE solar panels are designed for use in OFF THE GRID applications, and this one is especially good for mobile applications. So if you own an RV, this is the panel for you! Now you can let the sun have your back and enjoy a worry-free vacation or weekend getaway. This is the perfect place to start if you are new to letting solar power the electric needs of your RV. And if you find your electric needs are greater, you can install more than one up on the roof of the RV - and have 280 watts of solar power or more! It will also charge all types of 12V batteries commonly used in today's RV's, so you'll have backup power when you need it. Additionally, they are manufactured in accordance to ISO9001 standards and certified by IEC and CSA/US to assure electrical safety compliance.
If you didn't already know, one of the biggest advantages of solar energy is FREE ELECTRICITY! And again- you're cool enough driving around in an RV. If you have solar on the roof, your cool factor goes up even more. This 140 watt solar panel consists of 72 polycrystalline solar cells, and can works in temperatures as low as 49 degrees below zero and as high as 185 degrees Fahrenheit - this wide range gives you flexibility to install (or drive!) in any climate. 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.
And please be sure to watch the videos to the right. They are very helpful and informative - you'll learn how solar energy works, how to wire solar panels, the best orientation, and see and entire 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!
