The solar modules have a power conversion efficiency of 10.8% and "adequate" tensile strength and impact resistance, according to their creators. The research group said it used natural fibre composites as eco-friendly alternatives to conventional polyethylene terephthalate (PET) backsheets.

The academics also found that the production of the sisal fibers emitted about 60% less CO2 and required 50% less energy than PET backsheets. “Solar panels with sisal fiber sheets exhibit adequate tensile strength and impact resistance and reduce operating temperature by 2–3 C, ensuring stable operation and minimizing heat loss,” they added.
