Common Questions What surfaces can this flexible solar panel be mounted on? The Solar Technology Flexi panel can be bonded to flat or slightly curved surfaces (up to 3cm curve per metre) such as painted aluminium, metal, GRP, and fibreglass using a suitable bonding agent like Simson ISR 70-03. It also features pre-drilled 4.5mm holes for optional mechanical fixing. Can the included charge controller charge two batteries? Yes, the STCC10 10A Dual Battery Charge Controller is specifically designed to charge two separate battery banks simultaneously, making it ideal for vehicles or boats with both a leisure battery and a starter battery. Is the panel durable enough for outdoor use? Absolutely. The panel features an ETFE top layer known for its high resistance to UV radiation, chemicals, and mechanical stress. It also has a self-healing property for minor abrasions and is fully encapsulated for complete waterproofing, making it robust for various outdoor environments. Does the kit include everything needed for installation? The kit includes the 20W flexible solar panel with a 4m cable, the 10A dual battery charge controller, bonding agent, a waterproof cable gland, a fuse, and detailed installation instructions. You will need to supply your own battery/batteries and any additional wiring beyond the pre-wired panel cable for connection to the controller and batteries. Installation Notes Surface Preparation: Ensure the mounting surface is clean, dry, and free from grease or debris before applying the bonding agent. Airflow: When bonding the panel, follow the recommended glue pattern (detailed in instructions) to ensure adequate airflow underneath. This prevents heat build-up and potential warping. Cable Gland: Use the supplied waterproof cable gland to ensure a secure and watertight entry point for the panel cable into your vehicle or cabin. Charge Controller Placement: Position the charge controller as close as possible to the battery in a dry, protected location. Polarity: Always observe correct polarity (red for positive, black for negative) when connecting the solar panel, charge controller, and batteries. Professional Installation: If unsure about any aspect of installation, it is recommended to consult a qualified professional. Before You Buy Power Requirements: Assess your daily energy needs to ensure a 20W panel is sufficient for your intended applications (e.g., lighting, mobile device charging). Battery Compatibility: Confirm the 10A charge controller is suitable for your battery type and capacity. It supports 12V/24V systems. Mounting Surface: Verify that your intended mounting surface is compatible with the panel's flexibility and bonding requirements. Additional Components: While a comprehensive kit, ensure you have any necessary tools, additional wiring, or battery terminals not included in the standard kit. Please verify all specifications and compatibility requirements before purchase. Product specifications are subject to change by the manufacturer.
