Thrace Group in Greece has developed a fabric that reportedly will increase the floor albedo underneath a PV energy plant and the vitality yield of bifacial PV tasks by at the least 5%.
The producer of packaging options claims a small revenue for plant configurations with modules mounted on fastened pushed piles, with 0.8 meters of clearance between the strains of module and an inclination of 20 levels. It additionally claims bifacial good points of as much as 40%, which may range 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 and marketing supervisor of the plastics division of Thrace Group, mentioned pv journal.
The higher layer is manufactured from 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 entire 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 vegetation in Xanthi, Northern Greece, and in contrast the measurements with a management 1 MW set up in the identical space for one 12 months.
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 at the least 42%, leading to a complete enhance in vitality of at the least 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 at the least three staff. The set up price 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.
