Solar PV

A Turkish research team has analyzed how big changes in temperature can affect absorbance, light transmittance and reflectivity in two types of solar glass. The scientists demonstrated lower efficiency in solar cells and the glass itself were attributable to a large number of micro-cracks and deformations on the glass surface.

Japanese researchers have investigated the effectiveness of SiC devices in sub-kilowatt applications. A 790g device was tested in a mini PV generator system which included a battery and maximum power point tracker circuit in the same housing. Compared to traditional mini inverters the SiC device showed 3% higher efficiency.

Dubai-based Enerwhere has built an 80 kW floating array at a resort island in Abu Dhabi. The installation features bespoke modules from GCL and Sungrow inverters. The developer told pv magazine the business case was based on the fact the cost of diesel generator operation in such locations can run to $0.25/kWh.

The 5 MW Uliastai solar-plus-storage project will be located in the city of the same name in the western part of the country, around 1,100km from Ulaanbaatar. The facility is part of a plan to deploy 40 MW of solar and wind generation linked to energy storage in the nation’s western and Altai-Uliastai regions.

The Algerian electronics manufacturer said its solar business has not filed for insolvency. The company said it continues to operate as ‘normal’. The company added, it is working on two solar projects with a combined generation capacity of 100 MW.

Iberdrola has secured a long-term PPA from telecoms service provider Orange. The electricity will be delivered by a 328 MW solar plant that the Spanish energy group is building in Spain’s Extremadura region.

An unusually profitable fourth quarter has anchored an even rarer profitable year for SunPower, bolstering growing confidence in its decision to spin off its module manufacturing business into Maxeon Solar Technologies.

Tractebel will develop the basic design of three floating PV projects at the 52.2 MW Batalha hydropower project, which is owned by Brazilian state-run power company Eletrobras Furnas.

Chinese scientists have developed a cell with a new blade-coating method and BTP-4Cl-12, a kind of acceptor that is a derivative of the Y6 acceptor, which is widely used in organic PV applications. The researchers also claim that the cells can maintain good efficiency levels, even if its surface is lightly expanded.

The one-off charge for PV systems with generation capacities of 10-100 kW will be almost halved. The fee levied on 100 kW-1 MW arrays will come down by 1-30.7%, depending on system size.
