Solar forecasting based on all sky imaging, long short-term memory
A Dutch research team have developed a solar radiation forecasting model that uses the long short-term memory (LSTM) technique. The proposed methodology reportedly achieves better results than other forecasting approaches.
Winter air pollution weighing on solar generation in India
Solargis says that Indian solar operators have experienced below-average PV panel performance due to air pollution in each of the past five winters. Northern India experienced the worst air quality in decades this January, with data showing a 30% to 50% dip in solar irradiance due to high aerosol levels.
South Korea plans 120 GW space solar project
Two Korean research institutes are designing the 2.2 km × 2.7 km Korean Space Solar Power Satellite project with the aim of providing approximately 1 TWh of electricity to the Earth per year. The proposed system should use 4,000 sub-solar arrays of 10 m × 270 m, made out of thin film roll-out, with a system power efficiency of 13.5%.
Coupling heat pumps with roll-bonded photovoltaic-thermal collectors
Researchers in Sweden have analyzed how roll-bonded PVT collectors can act as secondary heat sources in ground-source heat pumps and have found they provide a better performance than conventional PVT panels. Their techno-economic analysis also showed roll-bonded PVT systems can be up to 9% more expensive than conventional installations based on sheet and tube absorbers.
High interest rates challenge global shift to renewables
A new report from Wood Mackenzie examines how the global shift to higher interest rates to combat inflation is squeezing the energy transition.
Sinovoltaics maps out Southeast Asian PV manufacturing sites
The latest supply chain report from the Hong Kong-based technical compliance and quality assurance company covers the Southeast Asia region, providing information about 50 manufacturing sites.
EDF launches UK heat-pump tracker tariff
EDF says its heat-pump tracker tariff is the United Kingdom’s first, as it will never charge its customers more than the price cap, guaranteeing savings of at least GBP 164 ($202) per year. It says it is also offering a GBP 750 discount on new heat pump installations.
German startup planning vertical floating PV plant
Germany-based Sinn Power plans to build a 1.8 MW floating PV system with vertically deployed solar modules. Construction is expected to start this summer.
Photovoltaic water pumping based on open-ended winding induction
Indian scientists have designed a water-pump drive system that is powered exclusively by photovoltaics. The proposed system configuration reportedly ensures effective use of both the solar modules and the motor.
Oman’s solar transition roadmap
SolarPower Europe says in a new report on solar development in Oman that the nation will need to install a minimum of 13 GW of solar by 2030 to meet its ambitious net-zero targets.
