Polysilicon capacity is unable to catch up with rapid capacity expansion in the mid and downstream segments, writes Corrine Lin, chief analyst for PV InfoLink. New polysilicon capacity requires big capex investment and a lead time of more than two years to complete construction and reach full operation. With unbalanced capacity between the upstream and downstream segments, polysilicon prices have been rising since the second half of 2020, with prices for mono-grade polysilicon surpassing CNY 200/kg ($27.40) in June 2021, up more than 250% year on year.

In his second article, Philip Wolfe founder of Wiki-Solar lists the world’s largest individual solar PV power plants. The biggest solar parks and other clusters of plants will be listed in subsequent blogs.

The global single-axis tracker market increased shipment volume by 40% year on year to reach 45 GW in 2020. This was despite significant pandemic-related supply chain turbulence that resulted in longer lead times for the delivery of components, the idling of steelmaking capacity in some key markets, container shipping dislocation, and widespread restrictions, particularly at ports. Most notably, this caused the cost of some commodities, such as steel, to more than double between 2020 and 2021. Jason Sheridan, a senior research analyst for IHS Markit, runs through some of the key developments in the tracker market.

This summer, IHS Markit published its annual global ranking of EPC providers that build in-house developed and third-party PV projects, based on last year’s installations. 2020 was a year of many contradictions, with lockdowns and increasing component prices taking their toll on many of the companies, both large and small. At the same time, EPC providers with their main share of business in mainland China and the United States had a remarkable year.

Solar energy pioneer and founder of Wiki-Solar, Philip Wolfe updates his series of blogs on the world’s largest solar power stations, first published in pv magazine in 2019. At that time, there were no single solar power plants over 1 GWAC. The record now is 2.2 GWAC.

South Korean researchers have tested four operational modes to combine residential batteries with balcony PV modules and have found that the best configuration is when solar is supplied to the load after the battery is fully charged. Charging the battery with the grid prevents the risk of full discharge in the absence of PV power, they said.

The scheme is open to companies specializing in district heating and offers rebates covering up to 15% of the total investment made to buy and install the heat pump, with developers being eligible for a maximum of DKK5 million for each project.

WattEV will build 1 MW solar-powered chargers to deliver 320 miles (515 km) of range to Class 8, 80,000-pound trucks in 30 minutes.

Ecuador plans to launch a 500 MW procurement exercise in November.

Edge Centres – a data center operator based in Queensland, Australia – has announced its first off-grid, 100% solar-powered facility in the state of Victoria.

Multiple factors affect the productive lifespans of residential solar inverters. In the second part of our new series on resiliency, we look at PV inverters.

BayWa r.e. and the Fraunhofer Institute for Solar Energy Systems ISE have built a 258 kW agrivoltaic system that hosts apple cultivation under four different crop protection systems. The system utilizes agrivoltaic technology with permanent, light-permeable PV modules that block rain, and tracking PV module tech that blocks rain only if necessary.

The new residential module of the U.S.-based manufacturer has a power conversion efficiency of 20.40%, a size of 1,076×1,957x35mm, and a weight of 21.3kg. The product is claimed to be compatible with next-generation, module-level power electronics.

The cell was fabricated by adding a special additive that improves the low crystallinity and high resistivity of the antimony trisulfide film. On top of the improved efficiency, the device showed an open-circuit voltage of 0.62 V, a short-circuit current density of 15.85 mA/cm² and a fill factor of 59.61%.

Multiple factors affect the productive lifespan of a residential solar panel. In the first part of this series, we look at the solar panels themselves.

The factory is under development in Eindhoven by Dutch start-up Solarge, and is scheduled to begin manufacturing activities in March.
