AGC (Asahi Glass) announced that it will start the sales of Lightjoule, an ultra-lightweight solar panel this month. Using Leoflex , a thin and strong chemically strengthened specialty glass, as the cover glass, AGC successfully reduced the panel weight of Lightjoule by nearly 50% compared to conventional solar panels. In recent years, large rooftops, such as those found on plants, warehouses, and public facilities, are increasingly used for solar panel installation.
However, some rooftops have loading weight restrictions and in such cases the user need to reduce the number of solar panels installed or carry out roof reinforcement work prior to installation. Being ultra-lightweight, Lightjoule can be installed on rooftops with loading weight restrictions without reinforcement work. A larger number of panels can be installed without the extra cost required by conventional panels. The lighter-weight solar panel will improve the efficiency of installation work and reduce installation costs.
