The one-stop marketplace platform will be launched in the US market next year. It will help homeowners find the best combination of products depending on their consumption profile.

The platform was launched by the National Center for Appropriate Technology. The clearinghouse features a library of peer-reviewed information, videos, podcasts, news, and a forum for agrivoltaics discussion.

The US company will manage charging and discharging the batteries, while keeping some electricity in reserve for backup power to the home.

This week, Russia joined forces with the United Arab Emirates to develop common hydrogen projects and similar moves were made by Chile and South Korea, Japan and Australia, as well as by France and Germany. French President Emmanuel Macron announced €2 billion in new investments.

Panasonic said the system is available in the U.S. with storage capacities of 17.1 kWh and 25.65 kWh. The product comes with a floor-standing battery cabinet and a hybrid smart inverter with 4 MPPTs.

The frameless solar panel has a light transmittance of 40% and nominal power of 235 W. The manufacturer offers a 30-year performance guarantee.

Estonian start-up Roofit.solar recently raised €6.4 million from a group of investors led by Germany’s Baywa r.e. The company will use the funds to commercialize its three BIPV modules with power outputs of 110 to 160 W. All products rely on a 0.5 mm metal back sheet with highly durable pural coating.

Several black swans have been circling over this year’s solar PV industry: rising raw material and product prices; supply chain issues and international logistics holdups; and power shortages in China, to name but the most disruptive. How is it possible for solar companies to survive under these conditions? According to Dong Shuguang, a PV veteran and President of Talesun Solar, they must focus on solar technologies like PERC, TOPCon and HJT, and product innovations that provide customer value.

The Netherlands storage industry association and the Dutch grid operators have proposed a faster phasing out of the net metering scheme to enable wider adoption of batteries among PV system owners. A 30% rebate on the purchase and installation of residential storage systems could help achieve the plan.

Scientists at Germany’s Fraunhofer Insititute for Solar Energy Systems (ISE) evaluated the performance of its newly introduced ‘Matrix’ approach to interconnecting shingled solar cells. The institute finds that, thanks to optimized current flows, energy yield of the Matrix approach could almost double that of standard shingled cell interconnection under random shading conditions.
