The 100W 12V Bi-Facial Monocrystalline Solar Panel is a high-efficiency solution for keeping your leisure batteries charged using free, renewable energy.Designed for permanent outdoor installation, its ideal for campervans, motorhomes, caravans, boats, off-grid systems and other 12V applications.Featuring advanced bi-facial solar technology, this panel captures sunlight from both the front and rear surfaces, allowing it to generate extra power from reflected light. Depending on the installation angle and surface below the panel, energy output can increase by up to 20% compared to a standard solar panel.Built for long-term reliability, the panel uses high-performance monocrystalline solar cells housed within a strong aluminium frame. Its fully waterproof construction ensures dependable performance in all weather conditions, providing years of maintenance-free power.The panel is supplied with 60cm of high-temperature resistant solar cable, fitted with male and female MC4 connectors for quick and easy installation. It can be connected directly to compatible solar systems or extension cables, while the MC4 connectors can also be removed if wiring directly into a solar charge controller.Innovative multi-busbar cell technology increases efficiency by extracting more energy from the available surface area. This allows the panel to deliver excellent performance while remaining compact, making it an ideal choice where roof space is limited. These cells also perform particularly well in warmer conditions, maintaining excellent output even at higher temperatures.Please note:If you are using this solar panel to charge a 12V battery or battery bank, a compatible solar charge controller (regulator) is required and must be installed between the panel and the battery.
