Solar panels with backup battery storage are nothing new: People have been using banks of lead-acid batteries to store solar power for decades. But those systems are bulky, require regular maintenance, rely on toxic and corrosive materials, and often must be housed in a separate, weatherproof structure. Generally,. .
Backup power in an outage is crucial for anyone looking to maintain basic comfort and communication abilities. Scale it up to a larger system, and you can go. .
Before I began this guide, my only experience with solar power was getting zapped by sun-powered cattle fences on a ranch in the high desert. So to give myself. .
