Honeywell has introduced a new black laminate film designed to help make black solar panels cooler and more efficient. PowerShield® Cool Black is a backsheet that helps reduce solar panel operating temperature by using an innovative and proprietary technology that reflects solar radiation. When panels operate at lower temperatures, their electrical components are able to operate more effectively and generate more power. Recently, all-black solar panels are increasingly being used on homes because they blend with rooftops.
Independent industry and university laboratory tests have shown that, during periods of peak power demand, solar panels using PowerShield Cool Black are as much as 7 degrees Celsius (12.6 degrees Fahrenheit) cooler, which can increase their power output by 2 to 3 percent. In turn, this increased power output can reduce a panel’s cost-per-watt generated by 2 to 3 percent.
“Heat reduction is a key factor in improving solar panel efficiency, and black panels are especially susceptible to increased temperatures,” said Jerry Buchanan, global business manager for Honeywell’s photovoltaic (PV) backing systems business. “Honeywell’s innovative new product, PowerShield Cool Black, can help keep black panels cool while making them more efficient, durable and able to blend in with their surroundings.”
