US scientists claim clear-sky irradiance model provides better results for module testing
Researchers at the American Institute of Physics have used the clear-sky irradiance model developed by the National Renewable Energy Laboratory to measure the degradation rates of solar panels at a testing field in Germany over five years. The scientists say the model, when combined with real-world data, offers an efficient tool to evaluate the aging of PV technology.
French researchers developing algorithm to identify losses in PV projects
Liten, a research institute of the French Alternative Energies and Atomic Energy Commission, is developing a method of assessing losses at every stage from the reception of solar rays to the injection of electricity into the grid, to ‘make it possible to optimize the maintenance of the power plants to guarantee their performance’.
Chinese recovery will begin before year-end, according to Jinko
The Shanghai solar manufacturer has revealed another set of record-breaking quarterly figures and says it will shift 18-20 GW of modules in 2020, en route to generating revenues of $1.17-1.23 billion.
Bangladesh sets solar import standards
Complaints about sub-standard, cheap PV imports from China – and notably, India – have been heeded by Dhaka, which has issued a requirement for modules, inverters, charge controllers and batteries to attain IEC electrical standards.
Longi demonstrates 20% bifacial boost
In a white paper published this week, Chinese module maker Longi Solar shares six months of data from a testing site in India that was built in cooperation with German testing institute TÜV Rheinland. The results show energy yield gains of around 20% for both bifacial mono PERC and n-type modules.
Bangladesh extends incentive scheme for domestic solar industry
PV manufacturers receive 10% of the value of their exported products as an incentive and the nation’s central bank has extended the program to cover this financial year. Bangladesh’s solar manufacturers have called for more, however, and point to more generous schemes to the west.
Bangladeshi industrial sector embraces leasing model for solar rooftops
The affordable public financing packages on offer for solar rooftops are attracting developers who have clients happy to lease out roofspace without any capital outlay in order to secure cheaper power.
Sub-standard PV equipment worries Bangladeshi solar developers
Visitors to this year’s Solar Bangladesh Expo have called for the implementation of quality standards on solar imports – action which the government is currently pursuing – with one industry insider rubbishing Indian-made products.
Longi unveils results of bifacial module test
The exercise, conducted on Longi PERC bifacial modules by Germany’s TÜV SÜD at a test field in China, showed surprisingly higher gains in panels getting light reflection from painted-surface and grassland albedo. It also showed, Longi claimed, bifacial panels operate at lower temperatures than single-sided alternatives.
A common language for bifacial PV
This week pv magazine was in Amsterdam for the sixth edition of the BifiPV workshop, where the discussion focused on the impressive achievements made by bifacial solar modules and the challenges the technology faces as it moves toward mainstream adoption.
