Advanced 9BB (Busbars) Technology 9BB (Busbars) design – The increase in the busbars, the increase in efficiency: The resistance and current on the cell are more evenly distributed, thus the resistance loss is reduced,conducive to current collection. Reduction of shadow and occlusion effect, so that the cell efficiency can be increased by 0.5-0.8%, and the power can be increased by 3-5W. Moreover,It can help reduce BOS cost and LCOE, reduce the risk of micro cracks, hot spot, and LID effect, and increase the efficiency and output of your solar panels. 350W Mono Solar Panel The solar panel is made from high efficiency monocrystalline solar cells. This means that it is designed to absorb the maximum amount of sunlight, so you have a reliable power source throughout your camping trip. You do not have to worry about not being able to charge your gadgets during cloudy days, because the solar panel can still generate power. The solar panel has a durable, anodized aluminum alloy frame making it sturdy. You do not have to worry about it being damaged, as the glass is made of high quality tempered glass. 20A Solar Controller * 12V/24V LCD display, USB Charge * Build-in industrial micro controller * Fully 4-stage Charge management * Solar Controller Charge with USB x 2 * Bual mosfet reverse current protection, low heat production * Suitable for lead acid batteries: OPEN, AGM, GEL * Rated Current: 20A Specifications: * Wattage: 350W * Max Power Voltage: 18V * Max Power Current: 19.44A * Maximum System Voltage: 1000V * Temperature Range: -40°C – 85°C * Solar Cells: Monocrystalline * Cell Tech: Mono-Si * Module Application Class: A * TUV Certification: Yes * Panel surface: High quality tempered glass * Frame: Sturdy anodized aluminum alloy frame * Solar Controller: 20A, Dual USB Dimensions & Weight * Dimension: 1080×710×30mm * Weight: 8.5kg Package: * 1× 350W Solar Panel * 1x Anderson Plug * 1× 1m Cable * 1x MC4 Connector * 1x Juction Box * 1× 20A Solar Controller with USB
