Midsummer and Medacciai are developing a BIPV solution for curved metal roofs in southern European markets, through a five-year deal.

Developed by U.S. researchers, the proposed coating solution is claimed to effectively melt ice and snow with temperatures down to -35 degrees Celsius. It was fabricated by using medium-chain triglyceride oil to plasticize two common industrial polymer polyvinyl chlorides and tested at a pilot facility in Alaska.

A German-U.S. research group has proposed a new model to treat PV installations as permanent assets, with maintenance being performed at regular intervals. Through the new metric, it found more convenient to operate a module with 0.5% annual degradation for 35 years, and a module with 0.2% degradation, for 50 years.

The European Council has approved a proposal to amend the EU rules on rates of value-added tax (VAT) to give member states more flexibility to set them. If adopted, solar panels for residential and ‘public interest’ applications would be included in the list of goods and services for which a maximum of 5% VAT could be levied.

The Czech authorities have extended, to February, the deadline to submit PV projects of up to 1 MW for the rebate scheme for small sized, ground mounted photovoltaics. According to Jan Krčmář, chairman of the Czech Solar Association, the lower than expected interest in the program may also be down to higher PV component prices.

The Italia Solare Forum event held in Rome last week has shown, once again, that permitting for both large scale and distributed generation projects remains the main barrier to remove to make Italy get the benefits of its huge solar potential. Despite recent progress, new provisions, and a slight increase in new PV capacity, the Italian market may be, again, unable to surpass 1 GW this year.

The three-phase inverter series features an efficiency ranging from 98.6% to 99.0%. The devices are equipped with up to 12 MPPT inputs and are able to provide up to 32 A MPPT current.

Saudi Arabian scientists have developed a perovskite sub-cell of a tandem device with a molecule that prevents the migration of ions into the perovskite film, even under humid conditions. The solar cell has an efficiency of 28.6%.

Scientists have developed a new model based on fault tree analysis to evaluate the frequency of fires caused by rooftop PV systems and assess system safety and reliability. They claim that the new tool has the potential to identify fault linkages in systems, highlight failure patterns before they arise, and compare multiple designs for safety.

A U.S.-Swedish research group has investigated the complex economic relationship between PV and heat pumps in cold climates under four different levels of electrification. It found that, compared to propane, solar heat pumps can reduce reduce costs by up to 20% and carbon emissions by 30%.
