The Italian manufacturer said the its new polyvalent reversible heat pump has a seasonal coefficient of performance of 4.44 to 4.59 and a seasonal energy efficiency ratio of 7.72 to 7.53. It can reportedly achieve a flow temperature of up to 55 C.

Scientists in Spain have created a semi-online technique to predict solar irradiance at different locations inside a photovoltaic plant. The proposed training approach is described as suitable for highly variable time series forecasting.

The latest irradiance sensor solution from Japan-based EKO Instruments provides continuous measurements in the field. Well-suited for bifacial PV systems, it supports the measurement of global horizontal irradiance, diffuse horizontal irradiance and direct normal irradiance, even in reflective and cloudy conditions.

The KGAL ESPF 6 Energy Transition Fund says it is investing in a 1,050 MW green hydrogen hub at Lubmin, a Baltic Sea port in Germany.

China-based Contemporary Amperex Technology Co. (CATL) has launched a new 376 kW/752 kWh product expanding its TENER energy storage series in response to logistics and geospatial challenges facing energy storage products in Europe. The new solution integrates with both string and central inverters, meeting the needs of both large-scale commericial and industrial as well as distributed generation applications.

Trina Solar claims it has developed the world’s first “fully recyclable” 645 W PV module with 20.7% efficiency. It made the panel with interlayer separation reagents, chemical etching technology, and wet chemical silver extraction tech.

Germany’s Fraunhofer Institute for Solar Energy Systems (Fraunhofer ISE) is developing “easy-to-use and reproducible” propane heat pumps to replace fossil fuel systems in multi-family homes, while exploring modernization options for various residential building types.

Sharp’s new IEC61215- and IEC61730-certified solar panels have an operating temperature coefficient of -0.29% per C and a bifaciality factor of over 80%.

An international research term investigated the feasibility of converting solar energy into chemical energy with the design of a hybrid device featuring a solar energy storage and cooling layer integrated with a silicon-based solar cell. Under testing, the device recorded a record energy storage efficiency and decreased the cell’s surface temperature by approximately 8 C under standard solar irradiation conditions.

The system was conceived to respond to Lebanon’s energy crisis and help homeowners become independent from grid electricity. Biogas production is used when PV power generation is insufficient and machine learning techniques help the system predict solar energy production.
