The Kings 100W Fixed Solar Panel is a slim glass panel in an aluminium frame, made to bolt onto a roof rack, a canopy or a caravan and stay there. We mounted it on the roof rack of our Prado, where it keeps the battery topped up whenever the car is in the sun, with nothing to set up. It weighs 6.6 kg and cost $149.
What’s in the box
A 100 W panel with Grade A monocrystalline cells under 3.2 mm tempered glass, in a black aluminium frame only 1.8 cm deep, with an Anderson-style plug on the lead. The mounting brackets are sold separately.

Fitting it
The panel bolts onto a rack with Kings brackets through pre-drilled holes in the frame, so there’s no drilling. On our roof rack it sits low and flat, and the Anderson plug runs down to the battery box. Once it’s on, it stays on: it charges whenever the sun is on the roof, including while you drive.
Output
100 W is the panel’s rating in ideal conditions: at its maximum power point it gives 4.95 A at 20.35 V. That’s enough to top up a battery for lights and phones, and to help a 12V fridge along in full sun, but on its own it won’t keep up with a fridge on cloudy days. Because it’s fixed, it can’t be angled at the sun or moved out of the shade, so park in the sun if you rely on it. Several panels can be wired together for more power.
Build
The tempered glass and the aluminium frame make it the toughest of the panels we’ve tested, built to handle rough tracks and weather, and the frame is shallow enough to sit low on a rack. The trade-off is weight: at 6.6 kg it’s heavier than flexible panels of more power.
How it compares
Our Kings 160W Semi-Flexible Solar Panel gives more power for less weight (3.9 kg) and less money, and it sits on our rooftop tent. The fixed glass panel is tougher and suits a roof rack, canopy or caravan. If your car is often parked in the shade, a blanket like the San Hima can sit in the sun instead. Our Kings solar comparison and camping solar panels guide compare them all.
Conclusion: Kings Fixed Solar Panel 100WConclusion
The Kings 100W Fixed Solar Panel is a tough, slim glass panel that bolts onto a rack and tops up your battery whenever the sun is on the roof, with nothing to set up. It’s fixed, so it can’t follow the sun, it needs brackets, and at 6.6 kg it’s heavier than flexible panels with more power. At $149 it suits a first permanent setup on a rack, canopy or caravan.

For a first permanent setup, yes: $149 for a tough panel that charges while you drive. For more power and less weight, the Kings 160W semi-flexible panel is better value.
