Solar industries bodies including SolarPower Europe, Germany’s BSW and Ukraine’s ASEU have joined forces to send a stream of modules, inverters and batteries to embattled Ukraine. The donations are critical as some hospitals have been without power for weeks, leaving surgeons to operate under headlamps.

Netze BW has increased the amount of hydrogen it is injecting into the regional grid of Oehringen, in the southwest of Germany, from 20% to 30%. pv magazine spoke with the project leader, Heike Grüner, about the next phases of the project.

Gerard Reid, co-founder of corporate finance advisory Alexa Capital, considers whether the EU is up to the task of dealing with the twin threats of the energy crisis and the pull of a revitalized US clean power industry.

SolarPower Europe says in a new report that households in Germany, Spain, and Italy can more than triple their savings by pairing PV with heat pumps. It said this combination helped families to save between 62% and 84% on their annual energy bills in 2022.

Fraunhofer ISE has presented the results of retrofit heat pump installations in multi-family homes in Germany. One demonstrator featured rooftop solar PV and a multi-source heat pump developed in partnership with Viessmann. It uses air and geothermal as heat sources.

Scientists from Germany’s Fraunhofer ISE and US panel maker Solaria have applied thermal laser separation and post-metallization passivated edge technology to tunnel oxide passivated contact (TOPCon) cell production. They have developed shingle PV devices that are more efficient than cells built with conventional laser scribing and mechanical cleaving methods.

Researchers have looked at whether Germany can substitute more gas with renewables-powered heat pumps or renewable electricity to reduce load hours at gas-fired power plants. They argue that heat pumps are the fastest way to cut German gas consumption.

MAN Energy Solutions is building an industrial-scale heat pump that generates steam without using gas. It will produce steam to dry dairy ingredients at a milk farm in New Zealand.

Germany’s cumulative PV capacity hit 68.2 GW at the end of January.

Viessmann has developed a heat pump for residential applications that can produce between 5.8 kW to 10.4 kW of heat. It has the capacity to heat 220 liters of domestic water, with a coefficient of performance (COP) of up to 4.8 for space heating and 3.14 for water heating.
