Multiple panels can be connected in parallel to increase current (Amps) for faster charging or in series to increase voltage (Volts) for higher voltage systems, provided your charge controller and inverter are rated for the combined input. Always consult the specifications of all connected components to ensure compatibility and safe operation. Typical Applications Application Description Motorhomes & Caravans Ideal for charging leisure batteries to power lights, pumps, and small appliances on the go. Boats & Yachts Provides reliable power for marine electronics, lighting, and essential onboard systems. Off-Grid Systems Suitable for remote cabins, sheds, or backup power solutions where mains electricity is unavailable. Small Commercial Use Powers security cameras, remote sensors, or lighting in small business and agricultural settings. Built-In Protection & Durability This Photonic Universe solar panel features a robust, sealed aluminium frame designed for long-term outdoor exposure. Its waterproof construction ensures reliable operation in all weather conditions, protecting the internal components from moisture and environmental elements. The advanced monocrystalline cells are engineered for durability, contributing to a long operational lifespan and consistent power output. Common Questions What is a 5 busbar solar cell? Busbars are metallic strips on solar cells that collect and conduct electricity. A 5 busbar design means there are five such strips, which improves current collection, reduces resistive losses, and enhances overall efficiency and durability compared to fewer busbars. Can this panel be used in the UK's variable weather? Yes, monocrystalline solar panels are known for their good performance in low-light conditions and variable weather, making them well-suited for the UK climate. The panel's waterproof design further ensures reliability. Is a charge controller included with this solar panel? No, this 120W solar panel is supplied without a charge controller. A suitable solar charge controller is essential for regulating the voltage and current from the panel to safely charge a 12V battery and prevent overcharging. Solarika recommends purchasing one of our compatible charge controllers. Can I connect multiple panels together? Yes, multiple Photonic Universe solar panels can be connected in parallel or series to generate additional power, depending on your system's voltage and current requirements. Always ensure your charge controller and other system components are rated for the combined output. Installation Notes Ensure the panel is securely mounted in a location with maximum sun exposure, free from shading. Connect the panel to a suitable solar charge controller before connecting to a battery. The included MC4 connectors facilitate easy connection; they can be cut if direct wiring to screw terminals is preferred. For permanent installations, consider professional installation to ensure compliance with local regulations and safety standards. Before You Buy Verify your system's voltage requirements (this panel is designed for 12V systems with a controller). Confirm the dimensions (1180 x 670 x 30 mm) are suitable for your intended mounting location. A solar charge controller is a mandatory component for safe and efficient battery charging. Consider your total power needs; multiple panels may be required for higher energy consumption. Always verify product specifications and compatibility with your existing or planned solar system components before purchase. This product is covered by a 1-year workmanship warranty from Photonic Universe, and solar cells are guaranteed to produce at least 90% of nominal power in 10 years and 80% in 25 years by the cell manufacturer.
