With a new system for floating photovoltaic power plants, engineers from Germany want to make the application cheaper, higher-yielding, and safer. The result is somewhat reminiscent of a pufferfish, which also gave the system its name.

The manufacturer has launched sodium-ion products online. Production has begun and will be easily scalable, according to the CATL chairman. Researchers have been keen to make the technology work as it offers a cheaper, more environmentally friendly alternative to lithium-ion products.

Sax Power has developed a new residential battery which it describes as a game-changer in the battery technology.

The battery system, which is aimed at increased self-consumption, can handle a maximum DC input power of 18 kW and 1000 V.

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

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.

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.

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.

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?

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.
