Thrace Group in Greece has developed a cloth that reportedly will increase the floor albedo below a PV energy plant and the vitality yield of bifacial PV initiatives by a minimum of 5%.

The producer of packaging options claims a small revenue for plant configurations with modules mounted on mounted pushed piles, with 0.8 meters of clearance between module traces and an inclination of 20 levels. It additionally claims bifacial positive factors of as much as 40%, which may differ relying on the configuration of the photo voltaic plant.

The Helios Mirror System (HRS) “combines a weed suppression layer to manage weed vegetation and protect the advantages of utilizing bifacial modules with an albedo enhancement layer that maximizes the photo voltaic irradiation acquired on the again facet of PV modules,” George Papagiannis, gross sales and advertising supervisor of the plastics division of Thrace Group, mentioned pv journal.

The higher layer is product of polypropylene resins, which give it flame-retardant properties, whereas the permeable membrane preserves the biodiversity of the soil and moisture content material, permitting for the whole restoration of the soil as soon as eliminated. The fabric is sturdy, reusable, and recyclable on the finish of its service life, with the highest layer lasting 5 years and the underside layer lasting about 10, in response to Papagiannis.

The Thrace Group put in the answer in two 1 MW bifacial PV crops in Xanthi, Northern Greece, and in contrast the measurements to a management 1 MW set up in the identical space for one yr.

The HRS installations confirmed a 69% enhance in albedo reflectance and a bifacial achieve enhance from 12% to 17%. The manufacturing of electrical energy devoted to the rear of the bifacial modules has elevated by a minimum of 42%, leading to a complete enhance in vitality of a minimum of 4.5%, in response to the Thrace Group.

“It’s as much as the stakeholders of a PV mission to find out which components of the plant should be optimized in order that AC capability doesn’t restrict the mission’s potential to maximise albedo-enhancing advantages,” mentioned Papagiannis

Thrace Group estimates that roughly 2,000 sq. meters of HRS might be put in per working day with a staff of a minimum of three staff. The set up value for the product is €0.014 ($0.015)/W, together with supplies, labor, and equipment. The corporate will exhibit the HRS answer at Intersolar Europe in Munich, Germany.
