Norway records 148.68 MW of new solar in 2024
Norway deployed 148.68 MW of solar in 2024, pushing its cumulative installed PV capacity past 750 MW.
Vertical rooftop PV performs better than conventional rooftop solar under the snow
A case study analysis by Norway’s Over Easy Solar has found that vertical rooftop solar panels outperform conventional rooftop PV systems during snowy months. Energy yield was up to 30% higher in the winter months in Norway, according to the company.
Controlling water-to-water CO2 heat pump for optimal coefficient of performance
Scientists have designed a novel control approach for water-to-water heat pumps that use carbon dioxide. They relied on a virtual heat pump for their tests. The coefficient of performance (COE) improved by up to 14.6%.
The Hydrogen Stream: BNEF forecasts sharper green H2 price drop by 2050
BloombergNEF says green hydrogen will fall from a current range of $3.74/kg to $11.70/kg to between $1.60/kg and $5.09/kg by 2050, while Longi Hydrogen has secured a conditional $6.14 million equity investment and cooperation agreement with HydrogenPro.
Assessing impact of fire on PV facades
An international research team has analyzed which factors contribute to fire accidents in PV facades and has found that the distance between the wall and the photovoltaic modules plays a crucial role. The scientists also said project developers should attentively consider what combustible materials are embedded in the wall cavity.
How to retrofit wind farms into hybrid wind-solar plants
A Norwegian-Swedish research group has used multiple linear regression to assess if 128 existing wind power plants in the Nordics could be potentially converted into wind-solar plants with cost-optimal PV capacities and good net present value (NPV) levels. Their modeling could potentially be used in all countries and latitudes.
Researchers complete Europe’s first PV soiling loss assessment
A European research group has adapted a soiling model for use across the continent, analyzing scenarios with complete and partial rain cleaning to calculate energy losses and increases in the levelized cost of energy (LCOE), marking Europe’s first techno-economic PV soiling assessment.
Norway defining new rules for energy communities
The Norwegian government says it is creating a new regulatory framework for energy communities. The new provisions will allow PV systems up to 5 MW in size to sell power and share surplus energy within specific industrial areas.
What happens when fire hits PV systems deployed on sloped roofs
An international research team has observed how fire propagates in PV systems installed on flat roofs and has found that a certain amount of energy is needed for a fire to start and propagate in the cavity below the solar panels.
Digital twin for autonomous aerial monitoring of PV power plants
An international research team has created a digital twin that purportedly enables analysis of different scenarios on PV plants’ aerial monitoring. The new tool is claimed to reduce the risk associated with real-world experimentation and help identify the most effective strategies to improve PV system monitoring.
