Hungary to launch renewables auction in July

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.

Cooling PV modules with passive technique based on finned heat sink

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.

Renesola warns of Covid-19 project disruption

The solar plant developer, which is now based in the States, was upbeat in its first-quarter figures but balance sheet borrowings remain a concern.


Hungary to hold another renewables auction this year

In its next procurement exercise, the Hungarian government will allocate 77% of the available renewable subsidies that it failed to assign in March’s auction.

Solar pavement for outdoor applications

Hungarian tech company Platio has developed solar pavement for outdoor applications in urban environments, homes, office buildings, shopping malls, and public infrastructure projects. The pavement consists of solar tiles that may cost between €50 and €80, depending on the size and characteristics of projects.


Hungary allocates 131.4 MW of PV in renewables auction

Solar developers secured 131.4 MW of the capacity awarded in the auction, while a biomass installation accounted for the remaining 500 kW of capacity. The national energy regulator will provide 15-year feed-in premium payments to the winning projects.


A commercial bifacial HJT solar cell with 24.1% efficiency

The cell is being manufactured by Switzerland-headquartered Ecosolifer with a manufacturing line provided by heterojunction specialist Meyer Burger at a 100 MW factory located in Hungary. The claimed efficiency is yet to be confirmed by an independent party.


Solar and wind generation outpaced coal in Europe last year

Renewables generated more electricity than coal in the EU for the first time ever in 2019, driving the sharpest reduction in the European power sector’s carbon emissions in three decades, according to a new report.


Varying capital costs favor wind over solar in Europe

Differing finance costs across the continent are likely to see wind-rich, high electricity demand nations such as Germany, France, Austria and Belgium forge ahead with renewables at the expense of countries with plenty of sun but where borrowing is expensive, according to a German study.


Getting the right module temperature with thermography

Researchers from Hungary have analyzed the thermal behavior of different types of PV module via thermography, and claim to have shown that theoretical models are insufficient to measure the maximum, minimum, and average temperatures of the panels. According to their analysis, glass-glass modules without frame showed the highest temperatures, while the lowest temperatures were measured for polycrystalline glass-backsheet panels with frame.
