Solar irradiance modeling method for east-west oriented vertical PV
A Finnish-Norwegian research group has investigated model chains for horizontal-to-vertical solar irradiance conversion in east-west oriented vertical PV systems located at high latitudes. They have found that accuracy and bias of the model chains are different for the east and west sides of solar array.
REC closes Norwegian polysilicon production facilities
Solar manufacturer REC blames high electricity prices for the recent closure of two Nordic polysilicon production facilities.
Statkraft bets on mix of renewables for hydrogen production
Statkraft used actual production data from wind and solar farms in Spain to study the feasibility and bankability of hydrogen projects. For a 1 MW electrolyzer to achieve a 40% utilization rate, five times more solar capacity would be needed, it said.
Vertical rooftop PV specialist switches on two more systems on green roofs in Norway
Norwegian vertical solar system specialist, Over Easy Solar, recently supplied a 102 kW bifacial commercial rooftop system, just a few months after supplying a 45 kWp system for a school rooftop. Both systems were installed on so-called green rooftops by the Norwegian project company, Solenergi Fusen.
Norwegian developer switches on northernmost ground-mounted PV plant
Store Norske Energi AS has installed a PV system in the Svalbard archipelago, the last inhabited strip of land before the North Pole. The company told pv magazine that the system could reduce the use of fossil fuels by 70% and potentially become a model for the Arctic transition to renewables.
The Hydrogen Stream: Netherlands starts building hydrogen network
The Dutch authorities have started building a national hydrogen network, while Fortescue has acquired a 12.5% stake in Norwegian Hydrogen.
Strategies to develop ‘solar neighborhoods’
A group of scientists across the world have created a list of recommendations that can help create solar neighborhoods. In a recently published study they highlight the importance of legislative frameworks and advanced computing.
Mitsubishi testing 5.5 MW pressurized alkaline electrolyzers in Japan, Norway
Mitsubishi has conducted short-term validation tests of its 5.5 MW pressurized alkaline electrolyzers in Norway and long-term validation tests in Japan. It plans to incorporate the design of these two single-stack pressurized alkaline electrolyzers into a US project.
Norsun announces temporary wafer production halt, layoffs
Norsun has temporarily suspended production at its plant in Årdal, Norway, as module oversupply in Europe is affecting pricing across the solar value chain, resulting in employee layoffs through the end of this year.
Bringing the benefits of affordable EV charging points to apartment blocks
One of the benefits of electric vehicle (EV) ownership is being able to plug your car into a wall at home ready for the following day’s commute but the idea is not so simple for apartment dwellers. Harald Seip, of EV charger company Elaway, suggests ways EU policymakers could solve that problem.
