Solar Sheets

The growth of the solar energy industry around the world is increasing demand for efficient and cost-effective materials for solar heat collectors in both domestic and industrial installations. While the front of a solar heat collector is comprised of photovoltaic cells, the back surface is just as important for the efficient collection of solar energy.

Mapal’s special polypropylene back-sheets for solar collectors are UV-stabilized, weather-resistant, adhesive and heat insulating. Because this special formula polypropylene can withstand higher temperatures than other polymers, Mapal solar sheets are ideal for use in high-temperature environments where they are exposed to strong sunlight. Because of their thermo-efficiency, they also have high-performance energy collection capabilities even at relatively low temperatures.

The solar back-sheets are usually colored black on one side and grey on the other, but other colors are available on request to suit different UV environments, and they can also be embossed. They are provided in maximum widths of 1500 mm and thicknesses of 0.4 mm to 1.2 mm.
