Researchers in Jordan have developed a technique utilizing acrylic sheets to mirror and soak up unused photo voltaic radiation in PV energy technology. The answer has the potential to scale back photo voltaic panel temperatures by greater than 14% and improve energy yields by roughly 2%.
Scientists at Mutah College in Jordan sought to scale back the working temperature of the photovoltaic panel by inserting clear acrylic sheets of various slopes on high of the modules at a distance of roughly 30 cm.
Researchers say that 3 mm acrylic sheets can mirror and soak up 10% of photo voltaic radiation with wavelengths under 1.1 μm, which isn’t sufficient for thrilling electrons in PV energy technology. They imagine that this unused radiation contributes to elevated panel temperatures and diminished efficiency.
“All this wasted photo voltaic radiation will solely warmth up the PV panel and improve the floor temperature,” the researchers mentioned.
For his or her experiments, the researchers used three 30-degree tilted monocrystalline photo voltaic panels, every with an influence of fifty W, dimensions of 630 mm x 540 mm x 18 mm, and weighing 3.3 kg. .
They used one panel as a reference with out the acrylic sheet, whereas the second panel had a sheet put in at 30 mm intervals with variable slopes of 15, 30, and 45 levels. . The third panel has a parallel-mounted sheet on the similar distance.
By means of evaluation and exams, the scientists discovered that the panel with slopes of 30 and 45 levels skilled the best temperature discount of 14.5%, whereas the panel with parallel-mounted sheet achieved- ot the discount of just about 10%.
“Reducing the PV floor temperature led to a rise in PV electrical effectivity and output energy of about 2% every,” they defined. “The outcomes of all of the experiments present that the set up of a transparent acrylic sheet can scale back the temperature of the PV floor, enhance the efficiency, improve the manufacturing {of electrical} vitality, and prolong the lifetime of the cell .”
They launched new know-how to “Set up of clear acrylic sheet to scale back undesirable photo voltaic radiation obtained by photovoltaic panels,” which was lately printed in Engineering Outcomes.
