The Spanish authorities are seeking 1.3 GW of clean energy and storage projects to provide flexibility, stability and security to the national electricity supply.

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.

Spain’s Soltec has developed a new dual-row, single-axis tracker with a tracking range of up to 60 degrees, offering compatibility with 60-cell, 72-cell and 78-cell modules.

AleaSoft and SolarPower Europe inform pv magazine that negative energy prices in Europe are related to the pandemic, low demand, insufficient storage solutions, and inadequate energy planning. They say this situation will likely continue into the summer.

Researchers in Spain claim to have recorded the highest power conversion efficiency result for a four-terminal tandem organic cell to date. The device is based on an ultrathin transparent silver electrode.

Sud Renovables has installed a pilot vertical rooftop PV system on one of its facilities in Barcelona, Spain. The array features two 500 W bifacial modules from US-based SunPower and two microinverters from Enphase Energy.

A group of researchers has identified a multispecies bacterial community that could reportedly increase the efficiency of hydrogen generation via microbial metabolism. The proposed hydrogen system achieved a more than double production rate compared to common biological hydrogen production technologies.

A Spanish research group has investigated how thermoelectric heat pumps may be used as power-to-heat technology to increase temperatures in thermal energy storage systems. It found the proposed system configuration may achieve an overall efficiency of 112.6% at at 135 C.

Spain’s cumulative installed PV capacity surpassed 25.54 GW at the end of December 2023, on 5.59 GW of new solar installations for the full year.

Storage Drop has secured a grant from the European Union to develop its PV-driven cooling system technology for low temperature environments. The system is based on compressed air energy storage technology and a hydraulic isothermal compressor with a water pump that compresses the air in an isothermal process.
