Researchers in Spain have calculated the potential self-sufficiency of rooftop solar in eight districts of Madrid, Spain. They have found that single-family homes can achieve self-sufficiency rates of more than 70%, while urban areas with high-rise buildings reach 30%.

It took eight years of field measurements for researchers at the RWTH Aachen University in Germany to estimate the usable capacity of home battery energy storage systems and develop a dataset covering 106 system years and 14 billion datapoints. Their key finding was that home battery systems lose about two to three percentage points of usable capacity per year on average, meaning good news for the industry as most warranties in the market can be met with the implementation of capacity reserves.

The Hellenic Association of Photovoltaic Energy Producers (Spef) is pushing the Greek government to stop issuing new grid connection licenses for renewable energy systems to address the nation’s escalating power curtailment issue.

Italian winemaker Svolta Srl has deployed an agrivoltaic facility at its vineyard in Apulia, Italy. The PV array allowed the cultivation of vines that are normally not viable at this latitude.

A Qatari research group has analyzed the performance of polyethylene terephthalate backsheets in real outdoor testing conditions in desert areas and has identified the main causes that lead to degradation. These include prolonged exposure to high ultraviolet radiation, high operating temperature cycling, and relative humidity.

Researchers in China have proposed a new lithium-free doping strategy to fabricate spiro-OMeTAD-based hole transport layers (HTLs) for applications in perovskite solar cell. A PV device built with a salt-doped HTL achieved a record-breaking efficiency of 25.45%.

Researchers have measured the power loss of a 50 W panel stationed in a 30-meter wave tank. Based on ten different scenarios, they were able to draw an empirical equation for the prediction of power loss, with the highest loss being measured at 12.7%.

A group of researchers in Thailand outlined a new methodology to identify the optimal temperature in two-stage cascade heat pumps using non-azeotropic refrigerants. Through their analysis, the scientists found that the coefficient of performance for simultaneous heating and cooling is affected by the pinch point temperature at the cascade heat exchanger, with lower temperature levels being responsible for a higher COP.

Shipment volumes are growing in the global solar tracker market as innovation in project development drives demand. Joe Steveni, of S&P Global Commodity Insights, takes a look at the factors shaping the commercial landscape for trackers, from agrivoltaics and undulating terrain to Indian ambition and the United States’ Inflation Reduction Act.
