Reducing solar module temperature with acrylic sheets – pv magazine International


Researchers in Jordan have developed a technique utilizing acrylic sheets to replicate and take in unused photo voltaic radiation in PV energy era. The answer has the potential to cut back photo voltaic panel temperatures by greater than 14% and improve energy yields by roughly 2%.

Scientists at Mutah College in Jordan sought to cut back the working temperature of the photovoltaic panel by putting clear acrylic sheets at completely different slopes over the modules at a distance of roughly 30 cm.

Researchers say that 3 mm acrylic sheets can replicate and take in 10% of photo voltaic radiation with wavelengths under 1.1 μm, which isn’t sufficient for thrilling electrons in PV energy era. They imagine that this unused radiation contributes to elevated panel temperatures and lowered 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 identical distance.

By evaluation and assessments, the scientists discovered that the panel with slopes of 30 and 45 levels skilled the very best temperature discount of 14.5%, whereas the panel with parallel-mounted sheet achieved- ot the discount of virtually 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 cut 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 cut back undesirable photo voltaic radiation obtained by photovoltaic panels,” which was lately revealed in Engineering Outcomes.
