PV InfoLink says polysilicon prices are clearly starting to fall. Meanwhile, Longi has lowered the prices of all wafers, and JA Solar has unveiled plans to build a new 10 GW factory.

JA Solar said the smallest solar panel in its new n-type product line has a power output of 435 W and a power conversion efficiency of 22.3%. The largest module in the series has an efficiency rating of 22.4% and 625 W of nominal power. Their temperature coefficient is -0.30% per degree Celsius.

JA Solar published data comparing its own modules, based on the 182mm wafer format, with others utilising the larger 210mm size over a six month period in field testing. The data show that the smaller of the two formats reached an average daily energy yield almost 2% higher. According to JA Solar’s analysis, the higher currents produced by the 210mm modules led to higher resistance, and more energy lost as heat.

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.

It remains unclear why Chairman Jin Baofang was detained, but the company said its operations will not be affected. The Paper, a Chinese state-owned media outlet, reported that Jin’s detention might be connected to the fall of Liu Baohua, the formal deputy director of the National Energy Administration, which has also been under investigation by the anti-corruption authorities since mid-October.

The 13 MW array was deployed in the Selangor state on the west coast of Peninsular Malaysia. The plant is selling power to local utility TNB under a 21-year PPA. The project’s levelized cost of energy is MYR 0.21608 ($0.051).

The new product, currently the most powerful panel on the market, was showcased at the SNEC PV Power Expo in Shanghai. Also presented at the fair was a 780 W product from Tongwei and a 660 W module from Trina.

As the solar industry moves to embrace ultra-high-efficiency modules, the Chinese PV heavyweight has unveiled TrinaPro Mega, the first integrated solar system in the world that incorporates 500W+ modules. The solution is expected to be particularly attractive for Australia’s utility-scale PV sector.

Chinese manufacturer JA Solar has announced a new 525 W+ panel and said the product will be available from the second half. Domestic rival Risen has shipped the first batch of its high-powered modules and intends to stick to pre-Covid-19 plans to ramp up production.
