Falling module prices will help PV post another record year after an estimated 132 GW was installed worldwide in 2020, according to an energy transition investment trends report published by Bloomberg New Energy Finance.

Batteries based on vanadium or zinc bromide represent the cutting edge of redox flow storage tech, an international research team has claimed. They have identified challenges and opportunities for about a dozen redox flow storage technologies, while providing estimates of their current and projected levelized costs of storage.

Canada-based Giyani Metals is planning to build a solar plant for its manganese mining site in Botswana. Three kinds of projects, with capacities ranging from 14 to 60 MW, are being considered. The power generated by the facility may be either consumed entirely by the mine or also sold to the grid under different scenarios.

The 452 kWp array features 1,300 photovoltaic panels across an acre of water split between two artificial lakes at the airport golf course.

Scientists in China found that capsaicin, the natural compound responsible for a chili pepper’s spicy flavor, can also act as a ‘secret ingredient’ in perovskite solar cells, making them both more efficient and stable. The group added capsaicin to the precursor materials of a common perovskite, leading to dramatic improvements in the resulting solar cell.

Developers have already connected 3 MW of capacity in what is purportedly destined to be the world’s largest PV array on a coastal tidal flat. The project, which is particularly challenging due to tidal fluctuations, will feature PV components designed to cope with salt and water damage.

Alongside all of the problems, 2020 has brought us a few promising solar module manufacturer initiatives and developments. Martin Schachinger of pvXchange.com looks back over the second half of the year and offers a quick look at what could be in store for 2021.

A new Wood Mackenzie report suggests that costs for front-of-the-meter battery storage systems in the Asia-Pacific region could fall by 30% by 2025. The declining costs are already having a palpable impact, as 2021 has opened with a slew of large-scale battery project announcements.

Tennessee-based Shoals Technologies has balance-of-systems solutions deployed on more than 20 GW of solar energy systems throughout the world.

Longi and Risen both announced plans to build up new module and cell manufacturing capacity. Furthermore, the State Power Investment Corporation (SPIC) has revealed it deployed more than 10 GW of solar power last year.
