New study claims PV industry is neglecting overirradiance issues
Overirradiance conditions may affect the operating performance of photovoltaic plants, the stability of the electrical grid, and the efficiency of inverters. A research team has warned these effects are currently not being given proper consideration by the solar industry.
July’s irradiance up in most of South America, down east of the Andes
In a new weekly update for pv magazine, Solcast, a DNV company, presents the solar irradiance data it collected for South America in July. The data show that South America experienced temperatures up to 15 C above winter averages, and that most of the continent saw higher than normal radiation. The Chilean Andine, especially Altiplano in the Atacama Desert, which has recorded the highest incidence of irradiance in the world, recorded values 10% above normal.
Argentinian lithium miner sourcing electricity from 100 MW solar farm
Minera Exar has started to extract lithium from the Salar Cauchari-Olaroz mine in Argentina, with part of its energy supply coming from the 100 MW Zonda solar farm, which is owned by oil producer YPF Luz.
Brazil added 6.8 GW of new PV in H1
Brazil installed 2.3 GW of large-scale solar and 4.5 GW of distributed-generation PV in the first six months of this year.
Brazil imported 7.8 GW of solar modules in H1
Brazilian consultancy Greener says that Brazil imported 7.8 GW of solar modules in the first half of this year, down 21% year on year. However, it says a reduction in distributors’ inventories and module prices could drive up cost competitiveness in the second half.
The Hydrogen Stream: Early adoption of green hydrogen leads to higher costs
Norwegian researchers say blue and green hydrogen could complement each other in the future, but early adoption of green hydrogen could result in increased hydrogen production and emissions.
Brazil prepares lithium extraction plan
The Brazilian town of Vale do Jequitinhonha (MG), which stands out worldwide in mineral production, is the stage of a multisectoral program for the use of Brazilian lithium. The government is now exploring the opportunities of the area in the energy transition.
Chile’s largest solar farm goes online
Enel Green Power has switched on the 398 MW Guanchoi solar plant in Chile’s Atacama region.
New methodology to avoid mispricing the value of PV projects
A new process is described as a tool to assess the value of deferring, relocating, or abandoning PV projects under development in uncertain market conditions. It reportedly allows accommodating different sources of uncertainties with different stochastic features, as well as accounting for the various managerial flexibilities embedded in most solar projects.
Suriname sets up auction scheme for renewables
Suriname is now seeking consultants for its new auction scheme to procure renewable energy. The nation has only deployed 12 MW of PV to date.
