Poland’s fourth largest energy company, Enea, will build a 30 MW solar plant for the Bogdanka coal mine in which the utility is majority shareholder. The project will sell power to the mine through a long-term supply deal.

The final average price for power generated by solar systems with a capacity of 100-500 kW came in at €97.48/MWh. The price for 500 kW-8 MW installations was €86.54/MWh. Only the latter category saw a fall in price compared to the previous commercial solar tender.

The Spanish manufacturer said the new three-phase device may reach a power output of 160 kWac in a single 75kg unit. The inverter features 1500 Vdc technology and is said to be able to reach a power output of 161 kW (AC) in a single 75kg unit.

Researchers from Canada have unveiled a new germanium deposition process which is said to eliminate threading dislocations and be significantly cheaper than previous approaches. The scientists say their technique creates nanovoids on the surface of the germanium layer which can attract and annihilate undesirable dislocations.

Inverter manufacturer Solaredge has filed three additional patent infringement lawsuits against its competitor, Huawei, in China. This comes after three similar legal actions against Huawei that had been undertaken by Solaredge in Germany last summer. While Huawei has decided not to comment on the matter, the Chinese manufacturer revealed that it had filed three patent litigation claims against Solaredge at a Chinese court this May.

Uzbek utility Uzbekenergo had received 23 offers for the 100 MW tendered solar plant. Two more solar tenders, with capacities of 400 MW and 500 MW, respectively, will be launched in the near future.

A new study shows solar may help reduce water pumping costs in a desert oasis of Mauritania significantly while reducing water losses. Researchers claim PV water pumping may also help prevent desertification.

An Italian research team has developed a device that it says can easily be integrated into a PV cell, and can boost its efficiency by converting more light particles into a high energy state before they are absorbed by the cell. The scientists claim that their innovation could offer a green‐to‐blue photon upconversion yield as high as 15%.

Recent investments into 11 GW of new coal generation capacity may result in reduced operating cashflows of $71 billion. That will occur, according to a report from the Carbon Tracker Institute, because solar and wind will become cheaper than coal in Japan by 2025 at the latest, despite high renewable energy costs at present.

Originally intended to commission 140 MW of storage, the tender drew three winning projects: a 50 MW system and two 30 MW facilities. Eirgrid has estimated the total value of the contracts at around €6 million per year.
