AGL Energy has completed the installation of a solar-powered microgrid with a 5.4 MWh battery energy storage system in Australia to support the transition of a commercial orchard’s operations from diesel to renewables.
The European Commission has shared updated documents with its member states for speeding up permitting procedures and designing auctions for renewables. It includes the use of non-price criteria in auctions, which the commission says will allow higher value-added projects to be rewarded.
Heavy rains recently triggered floods in Brazil’s Rio Grande do Sul state when Lake Guaíba and the Taquari River and Uruguay River overflowed, reaching more than 5.30 meters and affecting more than 1.95 million people. The death toll stands at 143, with 125 still missing. The authorities still have yet to assess the losses from submerged or affected PV plants.
Consortia featuring subsidiaries of Chinese solar module maker Longi and Chinese industrial conglomerate Shanghai Electric have withdrawn from a public procurement tender for a solar park in Romania. The European Commission opened two anti-subsidy investigations into their involvement, which have now been closed.
Greece added 1.59 GW of new solar capacity last year, and projections for the current year look strong. Curtailment remains the sector’s thorniest issue, however.
A scoping review examining the barriers to residential PV installations in South Africa says that no studies have considered how income effects the the likelihood of households adopting rooftop solar. The researchers claim this is “a glaring omission given debates on just transitions.”
A research group in China has tested how membrane-based floating PV platforms can operate in offgrid scenarios. Their analysis showed that, especially with high wave frequencies, this kind of floating PV installation may suffer from the floater bending stiffness, which could limit both in-plane and out-of-plane motion amplitude.
The authorities in Georgia are soliciting consultants for a 6.13 MW solar plant. The consultants will prepare a feasibility study and technical specifications. The deadline for applications is June 10.
Researchers from the Argonne National Laboratory have concluded that renewable energy could partially replace diesel fuel to power instruments and provide heat at the South Pole. They have proposed a solar, wind and energy storage hybrid that could reduce diesel consumption by 95% and save approximately $57 million over 15 years, after an initial investment of $9.7 million.
Indian scientists have designed an off-grid power system that relies on solar panels, lithium-ion batteries and Ćuk converters. The converters are the crucial components that enable the system to deal with varying input voltage due to changing sunlight conditions.
