Rhoss launches reversible heat pumps
Conceived for industrial applications, the novel heat pumps can reportedly deliver hot water at 65 C from -10 C up to 35 C of external air, and hot water at 55 C down to -20 C of external air. Their coefficient of performance reaches up to 3.47.
Italy’s latest renewables auction attracts 17.5 GW of solar project proposals
Italy’s first solar auction under the transitional FER X incentive scheme drew 17.5 GW in project proposals and an additional 2.87 GW in wind bids, according to state-run energy agency Gestore dei Servizi Energetici (GSE).
Italy launches floating PV tender
The Italian authorities have opened a tender to support the deployment of about 50 MW of floating PV capacity.
Italy, Portugal, Spain break daily solar production records
AleaSoft Energy Forecasting’s latest analysis finds weekly average electricity prices dropped across most major European markets last week, driven by lower gas and CO2 emissions prices and in some cases, an increase in solar energy production.
Improving perovskite solar cell efficiency, sustainability with micro-concentrators
Researchers in Italy are tackling two metal halide perovskite solar PV challenges, reduce the use of lead and extend stability of the power conversion efficiency, in a novel combination of micro-concentrators and picosecond laser processing.
Perovskite solar cell testing in underwater environments shows surprising efficiency results
Researchers in Italy have tested how perovskite solar cells could perform underwater and have found that, at very shallow depths, they may even achieve a higher power conversion efficiencies compared to reference devices operating under out-of-water conditions.
How albedo interacts with different rooftop PV system patterns
Researchers have simulated 160 cases of PV rooftop installation in southern and northern Italy. Among changing parameters were size and type of the panels, as well as their roof cover rate. The considered albedos were 20%, 40%, 60%, and 80%, representing different types of roof materials.
Italy extends construction deadline for agrivoltaic tender
Italy has extended the construction deadline for 1.5 GW of awarded agrivoltaic projects to June 30, 2026, after developers failed to meet the original timeline.
Researchers demonstrate technical feasibility of retrofitting PV-driven heat pumps in multi-family buildings
A research group led by Germany’s Fraunhofer ISE has conducted what it describes as the first empirical study on PV-assisted two-stage HP systems in existing multi-family buildings. Its findings show that substantial PV electricity exports result in greater avoided non-renewable primary energy use.
Eni sells 20% stake in renewables unit for €2 billion
Italian energy giant Eni has sold a minority stake in its Plenitude subsidiary to US-based investment company Ares for €2 billion ($2.32 billion).
