A solar generator pairs a large-capacity rechargeable power station — a big battery, at heart — with a set of portable solar panels, making for a versatile device that can provide backup power for your home during an emergency and do double duty for off-grid activities like camping, tailgating or even DIY projects around your yard. They’re safer to store and use and far simpler to maintain than gas generators, and with people more and more conscious of the threat of storms and wildfires, they make a lot of sense for emergency preparedness.
To choose the best solar generator, we tested 13 devices for an entire summer in the hot Florida sun to determine which device could reliably provide the most power with the least fuss. We considered factors such as portability, ease of setup, price, industrial design, technology, and innovation when making our final selections.
