Researchers in China have built a PV-powered air conditioner that can store power through ice thermal storage. The performance of the system was evaluated considering operating efficiency and stability and the scientists found that a device relying on a variable-speed compressor and an MPPT controller showed very good ice-making capability.

China-based Risen Energy is expanding its global footprint, the solar PV manufacturer and project developer announcing plans to construct a $13.35 billion mega production facility in Malaysia.

The American business is looking for module manufacturing partners as it plans to bring its ‘direct wafer’ production technique to India. The company uses molten silicon to form wafers rather than sawing ingots, thus eliminating dust waste and speeding up the process.

Investments in solar and wind in the Asia Pacific could double over the next decade compared to 2011 – 2020, hitting AU$1.7 trillion, according to new analysis by Wood Mackenzie.

Perth-based TNG Limited has signed an agreement with Malaysian green hydrogen company AGV Energy which will see its vanadium redox flow batteries integrated into the HySustain project to store solar energy for green hydrogen production.

The two solar manufacturers will get priority access to polysilicon produced at the planned fab in Inner Mongolia, which developer Xinte Energy has said will be fully operational by June 2023.

In a white paper, the three Chinese module manufacturers have reiterated the well-known refrain “bigger is not always better.” Experts from the three companies compared the BoS costs of 182mm-wafer-based modules and 210mm products, and found that the former have a slight advantage in racking, foundation, and land costs.

Wood MacKenzie’s energy transition modelling is predicting a primacy in the future low-carbon hydrogen economy for Australia. Thanks to the country’s solar irradiance and renewable energy expertise, as well as its relative proximity to major off-taker markets, Australia could be looking at export revenues of up to US$90 billion by 2050.

Such a decision, which industry body the CPIA is adamant has already been announced, could make all the difference to investors struggling with a surge in equipment costs fuelled by the polysilicon shortage. The all-important National Energy Administration, however, has yet to confirm whether the CPIA’s interpretation is correct.

Since July 2020, the PV industry has been experiencing price rises, which have affected almost all the components in a solar system. As these price increases spill out into higher installation costs, we see end user prices for solar rising for the first time in 10 years, threatening the competitiveness of PV in certain markets.
