Brand New 145 Watt 12 Volt Solar Panel From Solar Cynergy with cells from Q-Cells PV-SC145J12 Solar Cynergy photovoltaic modules are designed for commercial and domestic applications and suitable for both grid-tied and off grid systems. Solar Cynergy offers both high performance and reliability. The silicon solar cells, held by heavy duty anodized aluminum frames, are laminated with TPT & EVA for longer working life and high efficiency output. An ideal power supply for boats, traffic signs, lights, pumps, vehicles, RVs, homes, camping and caravans. Q-Cells wafers are cleaned with acids and alkaline solutions and electrophysically altered. An anti-reflection film made of silicon nitride is applied to them to increase their efficiency. And finally electrical contacts are attached. Q-Cells sells the finished cells to solar module manufacturers.
