11 popular framed glass panels scored on price per watt, measured output, durability and efficiency.
A rigid panel is the familiar aluminum-framed glass panel bolted to a roof, an RV or a ground mount. It can’t fold into a trunk, but it costs far less per watt than a portable panel: a median of $0.65 per rated watt here, against $1.15 for the portable panels we rank. If a panel will stay in one place, or you don’t mind carrying something heavy and awkward, a rigid one plus an adapter cable is the cheapest way to charge a power station. How we rank explains the scoring.
