The Dark Energy Spectre 200W Folding Solar Panel is built for basecamp setups and remote work sites where the grid is not an option and weather is not predictable. Armor-Flex protection with a 200-pound crush rating lets it survive being packed under gear without a dedicated case. Three panels chain together for a 600-watt array when a single panel is not enough to keep up with demand. What Our Gearhead(R) Experts Are Saying:"The Photo-Skyn cells keep charging even when the sky goes flat. I've had this pulling usable watts through overcast that would have stalled a standard panel."
