PolarGreen Tow is a portable PV system with a capacity of up to 6.5 kW. It can be used to supply power for electric cars or remote locations, or to provide energy during blackouts.

A Spanish court has ruled that Spain’s largest operational PV project – the 500 MW Nuñez de Balboa solar plant – occupies a piece of land that was illegally expropriated. Project owner Iberdrola must now shut down a large portion of the installation.

There is enormous demand for renewables to enter the grid, and for power purchase agreements to make use of them. However, as more renewables feed into the grid at intermittent periods, the risk of “revenue cannibalization” increases. Swiss consultancy Pexapark’s latest report looks at the “cannibalization effect” and how the solar PPA market can adapt.

The regional administration of Navarra said it is now developing the first 9-km portion of the 198-km solar plant that is planned to be deployed on Spain’s largest artificial irrigation canal network.

Shipbuilder Hermann Barthel has developed the world’s first push boat to combine battery-electric propulsion with hydrogen and fuel cell technology. Iberdrola and Fertiberia, meanwhile, have commissioned Europe’s largest green hydrogen production plant.

The German developer has committed to buying central inverters from Basque manufacturer Vizcaya, with the latter predicting it will supply the goods on a gigawatt scale annually.

The proposed methodology relies on geographic information and meteorological data. Project developers can use it to evaluate the potential energy production by a photovoltaic system for either a long or short time.

A Spanish-Italian research group was able to improve the efficiency and stability of a standard perovskite solar cell by adding nitrogen-doped carbon dots as an additive. The carbon dots were then blended with the perovskite precursor solution at two different concentration levels and both were deposited by spin coating on the perovskite layer.

Gamesa Electric’s new Proteus PV inverter represents an upgrade over the previous Gamesa Electric 3X series. It has an output of up to 4,700 kVA and is compatible with DC/ESS interfaces for the connection of storage energy systems.

German electrical equipment provider AEG is launching a shingled solar module for residential and commercial installations at this year’s Smarter E event in Munich, Germany.
