Bifacial solar modules increase returns by as much as 23% in brand-new study
- Bifacial double-glass solar modules have increased power yields by up to 23% contrasted to monofacial counterparts a research performed in China by JA Solar and TÜV Rheinland has actually discovered.
The research contrasted the power generation performance of bifacial double-glass modules established by JA Solar with monofacial mono modules, gotten in touch with different inverters and racking systems, in an attempt to offer recommendation factors for customers when selecting modules.
Four particular selections were modelled within a state-owned 100MW PV nuclear power plant in Delingha, Qinghai, China, with testing carried out by independent technological screening company TÜV Rheinland.
The very first selection combined JA Solar-made bifacial double-glass 310W modules with a horizontal uniaxial shelf and a string inverter, while the various other 3 test selections all used 310W monofacial modules from unrevealed producers. Distributed, centralised as well as string inverters were made use of on these 3 selections, while the racking was additionally readjusted.
The arrays neighbour each other and were improved the same land type, were developed and also created by the same building and construction group utilizing the same building cycle and also grid-connected time, and all were export-unlimited selections.
Experience data was taken in between 6 June 2019 and also 19 October 2020, with an overall of 485 days worth information was collected after some information abnormalities were gotten rid of.
TÜV Rheinland performed uniformity tests on the efficiency as well as high quality of the modules to make certain objectivity of the data comparisons.
The results assembled by TÜV Rheinland, which had actually thought about the effect of the tracking brace on efficiency, reveal that the bifacial selection created between 15.4% and also 23.3% even more power compared to the monofacial ranges of various tilt as well as inverter innovation, results which JA Solar stated demonstrated the "exceptional power generation efficiency" of bifacial modules over monofacial.
"The result of the examination once again confirms the exceptional power generation performance of JA Solar bifacial double-glass module, allowing it to come to be a good option to guarantee ROI for downstream clients," JA Solar said.
