The managing director of London-based energy infrastructure company Statera has told pv magazine a clean energy grid in the U.K. will require as much flexible gas plant capacity as battery storage.

The Chinese company is ramping up R&D efforts to try and fast-track commercialization of the more productive – and more expensive – battery tech. The news was announced as part of an uninspiring first-half update thanks to falling lithium salt prices.

A spokeswoman from the Chinese manufacturer of the Swan series of double-sided solar panels says monofacial modules will soon be consigned to residential use as the price gap between them and higher-yielding bifacial products rapidly closes.

The Chinese giant has argued its 166mm M6 product should be the new iteration used worldwide, even though larger products have been launched by rivals. Longi says the fact existing cell and module production lines can be adapted for the M6 means rising demand for solar worldwide can be swiftly satisfied.

The solar manufacturer today moved to reassure investors ahead of what promises to be another rocky set of first-half figures in two days’ time. The Hong Kong company says it wants to add another 3.6 GW of mono ingot and wafer capacity by early 2021.

The solar home system company, which enables customers to pay their solar electricity bill through an app on their mobile on a PAYG basis, has conducted a monumental funding round as it eyes expansion to become a fully-fledged pay-as-you-go utility.

The $376 million Travers Solar project has had the nod from the Alberta Utilities Commission. Construction on the subsidy-free facility, which will operate on a merchant basis, will start next year with an operational date set for 2021.

The wind power generator also has a 930 MW solar portfolio but did not take big steps in unsubsidized PV during the first six months of the year.

A mix of higher operating costs and ageing coal assets – plus historically generous solar tariffs – meant the utility banked more profit from the 1.53 TWh of solar electricity it sold in the first half than it did from 25.9 TWh of coal-fired power.

A tribute to Guy Sella has hailed ‘a brilliant man’ and ‘a revolutionary trailblazer’ who was ‘vibrant and energetic’ yet ‘down-to-earth and approachable’.
