Utility Scale PV

The Latin American country may see unprecedented growth for PV systems not exceeding 5 MW in size during this decade, according to Brazil’s state-run Empresa de Pesquisa Energetica (EPE) agency. New rules now under discussion in the parliament may further boost this market segment and lead, eventually, to another 30 GW of installed solar power.

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.

Brazilian researchers have proposed a new mathematical model to change parameters for wind and solar resources and different levels of energy demand. The model was originally conceived for tropical regions, but it can actually be used in any location. The new methodology models a highly complex system featuring wind turbines and PV modules, as well as solar collectors, fuel lines, gas boilers, engine-generator sets, recovery boilers, absorption and compression chillers, and grid electricity.

The Al Husainiyah solar plant, 200km south of Jordanian capital Amman, began commercial operations a week ago with more than 200,000 panels manufactured by 30% joint owner Philadelphia Solar.

Higher gas and electricity prices could open up new opportunities for short-term power purchase agreements in the Italian and European renewable energy markets, according to Stefano Cavriani, the founder and director of EGO Energy, an Italian company that specializes in PPA hedging. In a chat with pv magazine, he explained that electricity prices should not increase more, but they may stabilize at current levels, or slightly below the €100/MWh threshold.

The shallow pilings used on solar farms can offer relief to subsoil structures which might otherwise be threatened by regular plowing and, as Italy’s biggest solar project has demonstrated, site surveying for PV projects can unearth hidden delights.

Elsewhere, Uniper and the Port of Rotterdam have signed a deal to produce green hydrogen at the former’s site on the Maasvlakte extension of the port, and the Japanese government is helping Azerbaijan develop a green hydrogen and ammonia market.

GPH Ispat will build a solar plant on an artificial lake that is used to harvest rainwater, with panels to also be deployed on lakeside hills and the rooftops of the company’s main factory and offices.

Developed by Australian scientists, the demonstrated system is claimed to achieve a solar-to-hydrogen efficiency of 20% at a levelized cost of hydrogen (LCOH) of $4.10/kg. The direct solar hydrogen generation technology is powered by a tandem perovskite-silicon solar cell with an unprecedented high open-circuit voltage of 1.271 V, and a power conversion efficiency of 24.3%.
