Scientists in India developed a mathematical model to predict the output of solar cells and modules in the field. The model was developed and tested using both sun simulator and actual installed modules. The scientists state that their model can be applied to a PV installation anywhere in the world, and that by taking into account module degradation over time their forecasts can be as much as 26% more accurate than existing energy yield models.

On September 7, the country that consumes more power than any other nation introduced green energy trading. Two regions in China, Beijing and Guangzhou, were selected for the initial introduction of what will become the national green power trading market. Although it is still a pilot program, the market is expected to have far-reaching impacts on China’s energy transition away from coal. What do you need to know about it? Vincent Shaw in Shangahi sets out the details.

The inverter and battery manufacturer said it has been sitting on a record order backlog for the current three month window and the opening quarter of the new year, which may in part be down to a long Covid shutdown at its Vietnamese production base.

The continuous rise in solar panel prices may affect PV projects of up to 1 MW tendered by the Korea Energy Agency and the domestic solar module industry may not be able to provide the necessary production capacity to respond to the recent supply bottleneck.

Patriot Hydrogen has become the latest company to partner with the fast growing Singapore-based hydrogen-via-gasification outfit, CAC-H2.

Solar Philippines will tap stock market investors to back the first section of a solar project in Luzon it says will eventually be the largest in the region.

An Indian research group has used three different chemicals instead of commonly used hydrofluoric acid to separate silicon from the cell. The technique is claimed to be able to deliver recycled silicon with a purity of up to 99.9984%.

The new product has a power conversion efficiency of up to 19.3% and a weight of 11.2 kg. The module is produced with glass fibre reinforced plastic, which the manufacturer says reduces light reflection and opens up new assembly options.

Reports calculated that the single order would be enough to support production of 800,000 vehicles.

The past 12 months have proved profitable for polysilicon manufacturers, as selling prices have soared to levels not seen since 2011. However, with major new capacity expansions on the horizon from most of the leading manufacturers, and new players planning to enter the scene, the market balance looks set to shift.
