PV modules

Mali is set to host one of the world’s largest off grid solar+storage projects, as a 30 MW solar plant will soon be coupled with a 17MW/15MWh storage facility to power the Fekola gold mine. Finland’s Wärtsilä will supply the battery.

French renewables company Voltalia has secured a 25-year power purchase agreement from Crédit Mutuel Alliance Fédérale for a 10 MW solar plant and Germany’s Enerparc has signed a long term deal with Norwegian energy company Statkraft for a solar park planned in Bavaria.

Spanish researchers are proposing a customer-driven method described as an intuitive tool for investors and engineers to assess how self-consumption from solar generation can be profitable. The method is said to take into account economic parameters such as taxes, depreciation and the cost of financing.

State-owned Elektrani na Severna Makedonija will begin construction on a 10 MW solar plant at its redundant coal plant in Oslomej after signing the engineering, procurement and construction deal with a Turkish contractor. The utility is planning to tender a 10 MW extension of the plant and two more 50 MW solar facilities.

An Indian research team has analyzed around 300 scientific studies about PV panel waste containing carcinogenic metals. The researchers said solar module recycling is not economically profitable and policy support is necessary to avoid panels being dumped in landfill.

The U.S. business built and sold record-setting gallium-arsenide solar cells but its parent has seemingly run out of patience. Having failed to give its workers notice of the move, Hanergy is either in contravention of U.S. employment law, ‘faltering’ or subject to ‘unforeseen business circumstances’.

Solar electricity production increased by almost 9.2% in the January-September period, but installations barely changed from the first nine months of the preceding year.

The Spanish government has selected 55 solar installations in the procurement exercise. About 256 MW of the projects it awarded will be built on Mallorca, while Menorca, Ibiza and Formentera will host 61 MW, 6 MW and 2 MW of new capacity, respectively.

EOn has calculated the number of PV modules that could theoretically be installed on the Imperial space station from the popular film series. It concluded that even a small version of the station would be able to provide enough solar power to supply 2.5 billion households on Earth.

Scientists have observed that the efficiency of an organic PV device decreases by around 50% when it is exposed to 100-h light irradiation. They attributed this loss to increased resistance of the organic semiconductor layer.
