Charging & System Notes
This powerful 270W solar panel is designed to generate electricity for 12V or 24V battery systems. It is crucial to use a suitable solar charge controller (also known as a regulator) between the solar panel and your batteries. A charge controller safely manages the power flow, preventing overcharging and ensuring optimal battery health and longevity. The panel cannot be connected directly to batteries.
The panel is fitted with 2 x 0.9m cables (4.0mm² cross-section) terminated with waterproof MC4 connectors, facilitating straightforward integration into your existing solar setup or for linking multiple panels.
Typical Applications
| Application | Description |
|---|---|
| Motorhomes & Caravans | Ideal for curved roofs, providing discreet, flush-mounted power for mobile living. |
| Boats & Marine Vessels | High resistance to saltwater environments makes it perfect for marine applications. |
| Off-Grid Systems | Suitable for various off-grid setups where reliable, free electricity is essential. |
| Specialised Vehicles | Excellent for 4x4s, campervans, and other vehicles requiring a robust and flexible power source. |
Built-In Protection Functions
This Photonic Universe solar panel is engineered for resilience and long-term performance. Its robust glass fibre-reinforced plastic construction ensures durability, while soft, sealed edges protect against mechanical impact and help prevent long-term delamination. The sealed, waterproof design ensures reliable operation in all weather conditions, and its high resistance to saltwater makes it particularly suitable for marine environments.
Common Questions
What is the benefit of a rear junction box?
A rear junction box allows for a completely flush and level installation, as the electrical connections are hidden beneath the panel. This creates a sleek, professional appearance and eliminates trip hazards from cables on the panel's surface.
Do I need a charge controller with this panel?
Yes, a solar charge controller is essential. This panel generates a voltage higher than typical battery voltage and must not be connected directly to batteries. A charge controller regulates the power, protecting your batteries from overcharging and ensuring efficient power transfer.
How flexible is this solar panel?
This panel is semi-flexible, designed to conform to gently curved surfaces. While it is robust, it cannot be rolled up or folded. The manufacturer specifies a minimum bending radius of 2000mm, and it should only be bent lengthwise.
How should I clean and maintain the panel?
Regular cleaning with a soft cloth and mild soapy water is recommended to remove dirt, dust, and debris, which can affect performance. Avoid abrasive cleaners or harsh scrubbing. Ensure the panel is cool before cleaning. Check connections periodically for security.
Installation Notes
- Flush Mounting: To achieve the intended flush-mounted appearance, a recess must be created in your mounting surface to accommodate the rear junction box and cables.
- Mounting Methods: The panel is typically secured using a suitable adhesive (not included). Other options include self-tapping screws, tenax fasteners, or zipping, depending on the surface and application.
- Surface Preparation: Ensure the mounting surface is clean, dry, and free from grease or loose paint for optimal adhesion.
- Wiring: The panel comes with 0.9m cables and MC4 connectors. Ensure proper polarity and secure connections to your charge controller.
Before You Buy
- System Voltage: Confirm compatibility with your 12V or 24V battery system.
- Charge Controller: A solar charge controller is mandatory for safe and efficient charging. Ensure you have one or purchase a compatible model.
- Mounting Surface: Consider the curvature and material of your intended mounting surface, and plan for the necessary recess for the rear junction box.
- Cable Length: Assess if the integrated 0.9m cables are sufficient or if extension cables are required for your installation.
- Professional Advice: For complex installations, consider consulting a qualified solar installer.
Always verify product specifications and compatibility with your existing system before purchase. This product comes with a 2-year workmanship warranty, and the solar cells are guaranteed to produce at least 90% of nominal power for 10 years and 80% for 25 years from the cell manufacturer.
