Repowering old central inverters with new string inverters
In this pv magazine Webinar, we’ll hear about solutions for older pv plants with inverters that are between 6-12 years old and are no longer repairable by manufacturers. With examples from projects in the field which have seen Solis teams working with installers to provide a better solution.
Fluence introduces utility-scale battery for transmission networks
Storage specialist Fluence has launched Ultrastack, a battery energy storage system (BESS) for storage-as-transmission assets (SATA). It is designed to help network owners and operators to manage renewables curtailment, increase the use of power lines, and limit congestion.
The Hydrogen Stream: Sunfire delivers 10 MW of alkaline electrolyzers to RWE
RWE has revealed that it has received alkaline electrolyzers from Sunfire for a pilot project in Germany, while the European authorities have reached a deal on the continent’s renewable energy directive.
Chinese module prices to fall by 15% from Q4 2022 to Q4 2023, says CEA
Solar module prices will be pressured by rising industrial capacity this year, with capacities doubling in the ingot/wafer stages and potentially quadrupling for polysilicon by 2027, according to the latest PV pricing report from Clean Energy Associates (CEA).
China exported 29.6 GW of solar panels in January-February period
New figures from China’s General Administration of Customs show uninterrupted growth in global solar module demand. Chinese manufacturers exported 14.85 GW of panels in January and 14.82 GW in February.
Making the business case for solar-plus-storage
Much has been said about the benefits installing solar and batteries can offer to businesses but, as companies face mounting input cost inflation, is the upfront investment too much to bear or have volatile electricity costs made the decision a no-brainer?
Austrian manufacturer unveils propane heat pump for residential applications
iDM has developed a modular air-source heat pump that uses propane (R290) as the refrigerant. It can produce between 2 kW and 24 kW of heat and domestic hot water up to a temperature of 70 C. A larger version can produce between 10 kW and 50 kW of heat.
