Sonnen battery still running after 28,000 full charge cycles

Sonnen has published test results indicating the longevity of its storage systems after extended use.

A solar pavilion for India’s rooftops

India’s energy transition will not succeed without rooftop PV and roll-out is hindered not only by a lack of household finance, but by the fact many of the nation’s flat roofs are enjoyed by residents. Germany’s international development agency has proposed a solution.

A repair tape for cracked backsheets

Backsheet failures have plagued the industry, causing hefty financial burdens to many asset owners. DuPont has launched a product it says allows for easy repair of modules.

The long read: PV project owners – Drones or measurements?

Solar PV project owners need to make choices in terms of plant monitoring equipment. That can be electrical metrology equipment, but could also include new approaches such as using drones and machine-learning algorithms, or both.

The long read: Understanding solar MLPE

Module-level power electronics, most often in the form of power optimizers and microinverters, offer a range of value propositions, including advanced monitoring capabilities. But how much can the little box behind the module really see, and how much do operators actually need to know to keep a power plant running optimally?

The long read: Nickel and dime batteries to LFP

Lithium-ion phosphate batteries are making a comeback. Thanks to high nickel prices and limited feedstock supply, the EV industry is driving this change. There is no need to fret about the onset of slightly lower energy density, though, as this development has some benefits for the stationary storage market.

AI identifies a $14bn solar problem

How do you know when an inverter or module is under-performing? Monitoring services should shed light on problems but AI-driven digital asset manager Raycatch says much information is hidden behind a wall of “noise.” Breaking that wall with advanced data analysis could unlock billions of cost savings.

The long read: Compressed air storage to be more than just hot air in Israel

Solar-linked projects will be developed by domestic firm Augwind and will feature underground storage tanks. One of the systems will be built by French energy giant EDF and will feature a 20 MWh compressed air storage system and 5 MW solar array.

Tesla launches solar inverter

The EV manufacturer with big solar ambitions has finally leveraged its expertise in power electronics technology and launched a solar inverter.

The future of power electronics is distributed, aggregated and service oriented

IHS Markit released a white paper in which the analyst outfit shared some predictions for the power electronics market. First and foremost, inverters will become smarter, and after some power outages in key markets, these devices are gearing up to take on more grid stabilizing tasks, which hitherto had been reserved for synchronous generators.
