Powerful and lightweight: this solar panel packs 200w of power yet is only 0.2 inch thick and weighs only 10.5 lbs., making it easier to transport, hang, and remove. High conversion efficiency: with high efficiency monocrystalline solar cell, you will get greater power efficiency even though the panel is smaller than a traditional model. Maximizes system output by reducing mismatch loss; 100% el testing on all dokio solar modules, guaranteed no hot spots.

Pre-drilled holes on the back of the panel for fast mounting and securing. Dimensions: 39.50 inches x 39.00 inches x 1.50 inches. Pre-drilled diodes in junction box and a pair of mc4 connectors already attached to the panel. Mls-150wm is 12v 150 watt monocrystalline solar panel. High efficiency solar cells based on innovative photovoltaic technology. Strong aluminum frame manufactured to withstand a heavier snow load and high wind pressures, passing a snow load of 5400pa.

Withstand high wind (2400pa) and snow loads (5400pa). Item may ship in more than one box and may arrive separately. Guaranteed positive output tolerance (0-3%). High modules conversion efficiency. Excellent performance in low light environments. Renogy solar panels are framed in heavy duty anodized extruded aluminum with drainage/mounting holes and generate excellent performance in low light environments.

Sunpower solar cell: suaoki utilizes sunpower solar cell with a higher-than-average 23% to 25% efficiency and an internal blocking diode which prevents reverse current drain at night. Easy installation: unique frameless design features 4 metal reinforced mounting holes at each corner for fixing screws and for easy installation. Powerful and lightweight: this solar panel packs 100w of power yet is only 0.1 in thick and weighs only 4.85 lbs., making it easier to transport, hang, and remove. Superior durability: the water resistant semi-flexible solar panel is ultra durable and ideal for rvs, boats, tight spaces, or crowded areas that are typically off limits for traditional glass and aluminum models.

Bendable panel: the panel can be gently flexed to follow a smooth curve of 30 degrees max, and can be mounted on a coach roof, rv, boat, cabin, tent, or any other irregular surface.

The kit now includes 20a pwm charge controller, one pair 20ft 5awg tray cable, one pair 20ft 5awg adaptor kit mc4 solar cable and 4 set z brackets. Withstand heavy snow (up to 5400 pa) and strong wind (up to 2400 pa). Performs great in low light environments. Industrial and domestic solar panel with high modules conversion efficiency. Ideal output: 2000 watt hours per day, can fully charge a 50ah battery from 50% in less than 1 hours (depends on sunlight availability). 100 watts solar panel features: long service life up tp 25 years; high efficiency solar cells; special aluminum frame design; advanced cell encapsulation.

Pv solar panel diodes are pre-installed in junction box and a pair of 30 inches cables with mc4 connectors comes with the panel automatically.
