A new report by Instytut Energetyki Odnawialnej shows how Poland will deploy more large-scale PV. Growth is expected to be high in the 2021-22 period, with new capacity additions set to hit 2.8 GW.

The maximum size of eligible projects has been increased from 20 MW to 50 MW. The Hungarian government aims to contract around 390 GWh of generating capacity per year, with 40h GW to be reserved for the Small PVPP category, including installations between 300 kW and 1 MW in size. It will set aside 350 GWh for the Large PVPP group, which includes projects ranging in size from 1 MW to 50 MW.

Norway’s Statkraft is building a 2 MW floating PV array, first announced a year and a half ago, at its 72 MW hydropower plant in Albania’s Elbasan region. Norwegian floating PV specialist Ocean Sun has agreed to supply tech for the €2 million plant.

SolarPower Europe has predicted the volume of new PV capacity added this year will be 4% less than last year’s figure because of the Covid-19 crisis. At the end of 2019, the world had topped 630 GW of solar. For 2020, around 112 GW of new PV capacity is expected, and in 2021, newly installed capacity could be 149.9 GW if governments support renewables in their coronavirus economic recovery plans.

The Ukrainian government’s conference rooms have been stuffier than usual lately, as policymakers and renewable energy industry representatives attempted to thrash out a compromise to reduce the financial burden left on the administration by a feed-in tariff incentive regime which drove almost 2 GW of generation capacity. The resulting retroactive cuts to payments, outlined below by Ukraine-based lawyer Svitlana Teush, have at least had input from both sides.

The government will grant rebates to residential PV projects and may cover up to 90% of the costs of purchasing and deploying a rooftop array.

The pilotless, high-speed solar boat, now under development by Russian scientists, purportedly has unlimited power reserves. It could be used for marine patrols, search and rescue operations, and cargo delivery, they said.

The country reached 1.95 GW of installed PV capacity at the end of May, after installing around 653 MW of new projects in the first five months of this year. If the current growth trend continues over the next few months, Poland could become a gigawatt market in terms of annual additions for the first time this year.

A Pakistani research team has assessed the performance of a passive heat sink cooling technique in two different configurations: one using rectangular fins and one based on circular fins. The rectangular configuration was the best in terms of heat rejection. Modules mounted with this solution had a 6 C lower temperature than modules without cooling systems.

Scientists at Moscow’s Skoltech Center for Energy Science and Technology have developed a method of visualizing the formation of layers on battery electrodes during their initial operation. The observations reveal various mechanisms that could be optimized to improve battery performance and operational lifetime.
