Bifacial solar panels dramatically increase power generation efficiency through a double-sided light absorption mechanism that absorbs direct sunlight on the front side and utilizes reflected and scattered light from the ground and ambient light on the back side (e.g., highly reflective surfaces such as snow, sand, water, etc.) to achieve up to a 15% energy gain. Charge 12V batteries or 24/48V batteries by connecting multiple solar panels in series.
Upgraded Design
Utilizing the photovoltaic effect of semiconductor PN junctions, N-TYPE technology solar cells are able to provide photovoltaic conversion efficiencies up to 25.2%. Bifacial solar panels are designed with either frameless or transparent backsheets to maximize light transmittance and reduce shadow shading. Enhanced durability while allowing backside light to penetrate allows for a larger working area and higher power production.
Why choose18BB？
A.18BB solar cells have less internal resistance loss than 5BB solar cells.
B.18BB can reduce the impact of solar panel Micro-cracks.
C.The busbar of the 18BB solar panel is thinner , the light-receiving area is larger, and 18BB can get more power.
Durable Solar Panel
Our 12V 300 watt bifacial solar panels are constructed with corrosion-resistant aluminum frames that can withstand strong winds up to 2400Pa and snow pressure up to 5400Pa. The IP68 junction box and IP67 MC4 connectors are both waterproof, so you can use them outdoors with confidence. The transparent backside design accelerates heat dissipation, lowering operating temperatures and minimizing thermal decay;
EASY to INSTALL
The solar panels 300 watt has a built-in MC-4 connector, which can easily insert and pull out the solar controller. The pre-drilled hole on the back of the panel helps install it in your vehicle, RV or other place you need it. Each of our solar panels is tested and inspected before leaving the factory to ensure flawlessness. If you have any questions, please feel free to contact us.
Optimal Performance in Low-Light Conditions
With “High Power + Lightweight” as the core, this product redefines the 300W class device through size optimization (52.75 inches x 26.38 inches (approx. 134 cm x 67 cm), weight control (9.62 kg/21.2 lbs) and material upgrades, redefining the standard of portability for 300W-class devices. Its design concept balances performance and practicality and is suitable for multiple scenarios, making it an ideal choice for users seeking high performance and convenient experience.
Solar panel kit is an eco-friendly power source designed for boat, home off-grid charging, camping and outdoor activities.
