Italy’s annual new solar additions hit 5.23 GW in 2023

Italy installed 5.23 GW of new solar in 2023, bringing its cumulative installed PV capacity to 30.28 GW by December, according to trade body Italia Solare.

PV and prices, the fast uptake of solar in Brazil

In a new monthly column for pv magazine, the International Solar Energy Society (ISES) reports that Brazil currently has more than 85% renewable electricity, mainly hydropower, but with rapidly growing shares of solar and wind power. With 2.3 million rooftop PV systems installed so far and more than 90 million consumer units still available to go solar, favourable energy policies and cheap PV are encouraging the fast uptake of solar in the country.

Simulation model to determine coefficient of performance of air-source heat pumps

A Dutch research team has outlined a new method to assess the coefficient of performance of air-to-water heat pumps by considering ambient temperature and relative humidity. The model is based on the equalization of the so-called logarithmic mean temperature difference (LMTD), which determines the temperature driving force for heat transfer in flow systems such as heat exchangers.
