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.

The operation is part of the Portuguese utility’s plan to deploy another 13 GW of renewable energy capacity by 2025.

The funds should be allocated through multilateral and bilateral grants, concessional loans, guarantees and private investments. A task force will now seek to identify initial sources of financing for the electricity and coal mining sectors, as well as financing options for the development of electromobility and green hydrogen.

Given the Withhold Release Order (WRO) and the potential anti-circumvention tariff challenges, U.S. module supply risk is material, the analyst firm said in a note to clients.

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.

Scientists in India conducted a techno-economic analysis for a 100 MW production line for carbon-electrode perovskite solar modules, located in Himachal Pradesh, India. The analysis concludes that, even at the smaller scale, this emerging technology could achieve cost levels comparable with today’s silicon solar products.

The Ingecon Sun Storage 100TL battery inverter has an efficiency of 98.8% and a European efficiency rating of 98.1%. The device features maximum DC voltage of 1,100 V and an input voltage range of 570-850 V.

Developed by cleantech company Verditek, the flexible module has a 20.1% efficiency and a weight of 4.9kg. It can bend up to 35% using standard 160µ-thick crystalline cells.

After the ravages of Covid-19, electricity shortages in China have now raised costs for its solar manufacturers, with knock-on effects for developers in India too, again highlighting the dangers of relying on a single solar supply chain.

U.K. researchers have developed a battery with a photocathode made of vanadium dioxide, which is used to harvest light and store zinc ions and zinc oxide as a charge transport layer. The device showed an efficiency of around 1.2% and capacity retention of around 73% after 500 cycles.
