Spain recorded a 50% decrease in solar radiation due to bad weather in March – the biggest decline since the beginning of satellite records in 1994. By contrast, irradiation levels in Germany and the Balkans were 45% higher during the same period.

Japanese scientists have analyzed storage systems that combine PV and high-energy-density metal batteries. The rechargeable batteries have advantages such as low-charge voltage and high energy density, but stability and safety must be addressed before they reach commercial maturity.

The Regional Court of Apulia in Italy has ruled that the regional authorities must not deny permits to solar projects on agricultural land without considering how they combine electricity generation with crop cultivation and the raising of livestock. pv magazine spoke to Emilio Sani from law firm Sani Zangrando about the ruling’s potential consequences.

Municipal, regional and national authorities in France often have different views on permits for the deployment of solar. Marie Buchet, head of solar power at Syndicat des énergies renouvelables, spoke to pv magazine about four case studies. She said one-stop shops to unify all authorization processes could be the solution, as suggested by the European Union.

Approvals and planning procedures for solar parks are a major bottleneck for the energy transition. pv magazine recently spoke with a project developer about constraints and opportunities in Germany, ahead of the pv magazine Roundtables on June 28.

The main winner of the first renewables auction in the Philippines was developer Solar Philippines Nueva Ecija Corp. (SPNEC), which secured five solar projects, or 1.35 GW of capacity.

Norwegian scientists have tested a new floating PV system concept at a water reservoir in Sri Lanka. The system is made of composite beams to support the solar panels and high-density polyethylene (HDPE) pipes to provide buoyancy.

Average polysilicon prices ranged from CNY 273 ($40.82)/kg to CNY 280/kg this week, according to an industry association in China.
