Solar energy pioneer and founder of Wiki-Solar, Philip Wolfe updates his series of blogs on the world’s largest solar power stations, first published in pv magazine in 2019. At that time, there were no single solar power plants over 1 GWAC. The record now is 2.2 GWAC.

The comparison of two solar cladded roofs in Sydney, Australia, one bare beneath its panels and the other adorned with native grasses and plants, has found the panels on the green roof were, on average, 3.63% more efficient, producing an average daily output 13% greater than the conventional roof. The improvements are believed to stem from the lower temperatures on the green roof, thanks to its plants – which also provided a plethora of additional benefits.

Large-scale solar parks will be key to India’s transition to clean and green energy. Such parks are already being built or planned in States like Gujarat, Karnataka, Madhya Pradesh, Rajasthan, and Uttar Pradesh. However, there is still scope for forward-looking and well-aligned policies across States to make the most of this global phenomenon. 

Professor Thomas Nann told pv magazine Australia that a breakthrough idea was almost too simple: “Actually when we submitted the patent in the first place, the patent officers came back to us and said ‘well, that’s too trivial’ and we made exactly that argument – why did no one else do that then?” said Nann.

Two different devices designed by German manufacturer Bosswerk can feed up to 300 or 600 watts into the home network. The company offers a 12-year guarantee.

With many developers now working on solar+storage projects, it’s time to look more closely at specific business plans. Siobhán Green, lead on battery storage in continental Europe for Everoze, looks at three key questions.

Often sidelined by nickel and cobalt when it comes to batteries, the metal manganese is finding proponents in science and industry – in particular, by those attempting to avoid supply and cost issues. Ian Morse reports on the role of manganese in battery cell production.

Until 2016, Nepal suffered from chronic power shortages. At that time, just 65% of the country’s population had access to electricity. Assessing the situation, the International Renewable Energy Agency (IRENA) estimated that the country has the potential for 2.1 GW of installed PV capacity. Although the Nepal Electricity Authority (NEA) has officially been able to buy solar power under long-term PPAs since July 2014, the majority of projects granted these contracts have been large-scale hydropower plants. Following slow activity, plans are finally afoot, however, to boost the country’s solar footprint.

The sticker is based on a blockchain technology developed by German start-up Authentic Network. Meyer Burger uses the application for the photovoltaic modules it produces in its new factory that opened in Freiberg at the end of May.

In the first installment of a new monthly blog by IHS Markit, Edurne Zoco, executive director for clean energy technology, writes that high prices and increased freight costs are putting solar PV procurement teams under extreme pressure, particularly those teams with connection deadlines this year that were anticipating a more favorable pricing and logistic environment in the second half of 2021.
