IEA report appears to acknowledge 2050 net zero may be beyond us

A study into the clean energy tech innovation rate required to keep global heating under control may suggest concepts such as lithium-air could yet keep us to the mid-century ambition, but it is also starting to contemplate the temperature rise to be expected if we only achieve net-zero by 2070.

Lobbying clears the way for European solar trade show in September

The organizers of the Solar Solutions International event which was postponed in March have persuaded the Dutch government industry events should not be subject to the same Covid-19 restrictions as concerts.

Chinese PV Industry Brief: Tongwei freezes cell prices, state body opens procurement round

Longi has also joined the 500 W-plus module club with its new Hi-Mo5 product, while Sunport has announced to expand production of its MWT module.

Longi launches 540-Watt Hi-MO5 module

The Chinese manufacturer has debuted two models in the new bifacial, double-glass series to join the scramble for a slice of the 500 W-plus market and to stake its claim to have the 182mm, M10 wafer adopted as the industry standard.

Efficient rooftop solar+storage without MPPT

A German research group is trying to determine whether the combination of solar and storage with direct coupling and without the aid of maximum power point tracking (MPPT) electronics is feasible. According to its findings, this particular configuration might be efficient, but it will likely require special panels and batteries.

A flexible approach to offshore solar

Scientists in the Netherlands are trialing a floating solar installation based on flexible thin-film PV modules. The idea behind their concept is that such modules, in combination with a newly designed flexible racking system, will create a system able to roll with the movement of the water, rather than attempting to defy it.

Predicting the future for smart PV

Over the next five to 10 years, renewables will assume a larger role as a main power source for electric grids, and PV has a particularly bright future. Considering the latest trends in power electronics technology, PV is quickly evolving down the path to intelligence. Given the rapid development of emerging information and communication technologies (ICT) – such as AI, cloud computing, big data, and 5G – Huawei has an idea of what’s in store for the future of solar PV.

Sub-nanometric particles to stabilize lithium-oxygen batteries

The storage technology promises ten times the energy density offered by lithium-ion batteries but notorious cycling instability remains a concern. Researchers in South Korea may have come a step nearer a solution.

Shielding PV against Earth’s magnetic field

Researchers in Kenya are seeking to reduce the influence of the Geomagnetic field on PV panel performance by replacing aluminum module frames with a steel cage. They have specified they have been unable to quantify costs related to the solution, and that more research is needed.
