New research from Serbia claims air-polluted urban climatic conditions may not only induce maximum power point (MPP) tracking problems in PV systems but also reduce power yield by up to 30%. The scientists also said that soiling may significantly affect the functionality of single-stage inverters operating in grid-forming mode.

Scientists led by the Karlsruhe Institute of Technology have designed panel-like photoreactors relying on a water-splitting photocatalyst that could produce hydrogen on rooftops or dedicated solar farms. They claim the photoreactors have high economic potential because of their ‘extremely’ low costs.

Helena Li, president of Trina Solar’s global cell and module business, spoke to pv magazine at the recent SNEC trade show in Shanghai about the PV industry’s oversupply challenge. Li said the company is considering opening a factory in Europe and expressed optimism about future cost and price declines.

The research group led by Professor Martin Green has published Version 62 of the solar cell efficiency tables. There are 21 new results reported in the new version, a record number for the Tables.

In the second interview of a series held at Intersolar 2023, pv magazine spoke with Karen Tang, Director – Editorial Lead Europe at Singapore-based market research company OPIS, about current price trends in the industry. She said solar panels may soon be bought at an average of USD 0.185/W but she also revealed that offers under USD 0.15/W are now becoming more frequent. Furthermore, Tang said prices may continue to drop in the future, with the bottom line being difficult to determine. Much will depend on the actual manufacturing capacity we will see coming online, which may not match the huge number of recent announcements released by module producers.

A research group in Ghana has conducted a series of tests to assess the performance of polycrystalline solar modules in PV systems operating in their home country for at least 5 years. They found that the vast majority of the panels may ‘fail’ before 20 years in operation under outdoor conditions.

The government of the Philippines is set to hold the country’s second renewables auction on June 19.

Cambodia’s Ministry of Mines and Energy has published a document outlining principles to permit the use of rooftop PV. The new policy replaces a monthly capacity fee for rooftop systems, with a tariff calculated based on an intricate formula.

Developed by Chinese researchers, the novel hybrid storage technology may achieve an efficiency of over 80% and be applied in distribution and transmission grids. The proposed combination is reportedly able to offer the advantages of gravity energy storage and power-based storage systems in a single solution.

A Dutch research group has used a series of techniques from the automotive industry to develop a novel methodology to repair glass in double-glass solar panels. Their experimental work represents the step towards transforming glass-damaged solar panels from waste into valuable products.
