HQST 100 Watt 12V Monocrystalline Lightweight Solar Panel for RV/Boat/Other Off Grid Applications Top ranked PTC rating; high module conversion efficiency; fast and inexpensive mounting. The junction box is sealed and waterproof, and a pair of 10 inches cables (we keep the panel cable short to avoid the cable shade from the solar panel) with MC4 connectors comes with the panel automatically. Can be affixed by adhesive, grommets, zip ties or velcro; can be installed without costly structural roof reinforcements. Holes on panels are pre-drilled for fast mounting and securing, perfect for non-permanent installations. Maximizes system output by reducing mismatch loss; 100% EL testing on all HQST solar modules, guaranteed no hot spots. Ideal for storage in tight spaces or crowded areas that are typically off limits for traditional glass and aluminum models. Please note: do not bend your panels.
