Panel Technology & Design
| ETFE Top Layer | The Ethylene Tetrafluoroethylene (ETFE) surface provides a durable, self-healing, and anti-slip finish, making the panel resistant to minor scratches and suitable for walking on with soft deck shoes. |
| Encapsulation & Waterproofing | A robust six-layer laminate completely encapsulates the solar cell circuit, protecting it from moisture and harsh environmental conditions. The junction box is silicon-injected to prevent water ingress. |
| Optimised Junction Box | Features a unique curved design for superior adhesion and no snag lamination. It is mechanically fixed and bonded, with strain relief for the PV cable to prevent accidental dislodgement. |
| Shading Diodes | Integrated diodes help prevent damaging hot spots and power loss when the panel is partially shaded, common in mobile applications. |
Typical Applications
| Application | Description |
|---|---|
| Campervans & Motorhomes | Ideal for roof mounting due to lightweight and semi-flexible nature, providing auxiliary power for leisure batteries. |
| Marine Vessels | Suitable for boats and yachts, resisting saltwater spray and offering an anti-slip surface for deck installation. |
| Off-Grid Sheds & Cabins | Provides reliable power for lighting, small electronics, and charging systems in remote locations. |
| Portable Power Systems | Can be integrated into custom portable solar setups for camping, expeditions, or emergency backup. |
Built-In Protection Functions
The Solar Technology Flexi panels are engineered with several protective features to ensure longevity and reliable operation. These include integrated shading diodes to prevent hot spots and power degradation under partial shading conditions • a fully encapsulated, waterproof design for resistance against moisture and environmental elements • and a robust ETFE top layer that offers enhanced durability and self-healing properties against minor surface damage.
Common Questions
Do I need a charge controller with these panels?
Yes, a suitable solar charge controller is essential to regulate the voltage and current from the solar panels to your battery, preventing overcharging and optimising battery life. For a 20W panel, a small 10A PWM or MPPT controller is typically recommended, especially when connecting multiple panels in parallel.
How should these semi-flexible panels be installed?
These panels can be bonded directly to flat or slightly curved surfaces (up to 3cm curve per metre) using a suitable adhesive like Simson ISR 70-03. They also feature pre-drilled 4.5mm holes for mechanical fixing if preferred or required. Ensure proper airflow underneath the panel to prevent heat build-up.
Can these panels be walked on?
The ETFE top layer is designed to be robust and can be walked on with soft deck shoes, making them particularly suitable for marine applications where deck space is at a premium.
What is the benefit of the ETFE coating?
The ETFE (Ethylene Tetrafluoroethylene) coating provides a highly durable, UV-resistant, and self-cleaning surface. It has a 'memory effect' that allows it to self-heal from minor abrasions, enhancing the panel's lifespan and maintaining performance in harsh outdoor conditions.
Installation Notes
- Surface Preparation: Ensure the mounting surface is clean, dry, and free from grease or debris before bonding or fixing.
- Adhesive Application: If bonding, use a marine-grade or outdoor-rated adhesive suitable for solar panels. Follow the adhesive manufacturer's instructions carefully, ensuring a pattern that allows for air circulation beneath the panel to prevent heat build-up.
- Mechanical Fixing: Utilise the pre-drilled holes for secure mechanical attachment, especially in high-wind or high-vibration environments.
- Cable Management: Route the 4m UV stabilised PV cable securely, protecting it from sharp edges and potential damage.
- System Integration: Connect panels to a suitable solar charge controller before connecting to a battery bank to prevent damage.
Before You Buy
- System Voltage: Confirm these 12V nominal panels are compatible with your existing or planned solar system voltage.
- Charge Controller: A solar charge controller is required for safe and efficient battery charging. Ensure you have one suitable for the total wattage of your array.
- Cabling & Connectors: Verify you have appropriate cabling and connectors for integrating the panels into your system.
- Mounting Surface: Assess your intended mounting surface for suitability for bonding or mechanical fixing, considering any curvature.
- Power Requirements: Calculate your daily power consumption to ensure 5 x 20W panels will meet your energy needs.
Always verify product specifications and compatibility with your specific system requirements before purchase. Consult a qualified installer for complex setups.
