A Norwegian company has developed a way to melt snow on modules to avoid excess weight on roofs and panels, especially on large commercial and industrial arrays. A control system measuring snow density is linked to DC power supply units to warm the panels.

Despite the country’s difficult struggle with the COVID-19 outbreak, the Italian solar market is sending some encouraging signs. Italian lender Intesa San Paolo has awarded a €55 million credit facility to Canadian Solar for a portfolio of 12 unsubsidized solar projects.

Spanish utility Iberdrola plans to link a 100 MW/20 MWh solar-plus-storage plant to hydrogen production in Puertollano, in southern Spain. The project will require an investment of up to €150 million euros and will be one of the largest installations of its kind in Europe.

The utility will build the project this year on 164 hectares of land just outside of Berlin. It will be the largest solar park to be constructed outside of Germany’s incentive scheme for solar and renewables.

The Swedish Energy Agency this week said solar power supplies will increase from 400 GWh in 2018 to 1.7 TWh in 2022. Total energy supply in the country is expected to decline from 551 TWh to 526 TWh in the 2019-22 period, due to the shutdown of several nuclear power plants.

Researchers from the United States have proposed a new electrode design for fractal solar panels that combines the typical aesthetic advantages of the technology with the efficiency of busbar design. The proposed pattern is based on the fractal tree structure known as H tree, or T-branching, which is a geometric shape consisting of a repeating pattern that resembles the letter H. The hybrid H-tree/busbar pattern showed power losses that are close to those of standard busbars.

The Ministry of Energy of Republika Srpska is seeking proposals for its first large-scale PV project. The solar park is planned to be located in Bileća, in Bosnia’s southernmost part.

The national Green Houses Program grants incentives for the installation of solar water heaters, PV systems with a generation capacity of up to 10 kW, heat pumps and small wind turbines.

US scientists claim to have discovered a membrane which could lead to cheaper large scale flow batteries. The material is an ion-selective, aqueous-compatible polymer with intrinsic microporosity known as AquaPIM and is said to have tunable thickness and high conductivity in aqueous electrolytes.

Many solar factories in China are starting to resume production, suggesting that concerns about supplies of PV components could soon begin to ease. Nevertheless, the temporary standstill will have an impact on the global solar market, as the implementation of some projects will probably be postponed until next year.
