Advansor launches CO2 plug-and-play heat pumps
The Danish manufacturer said its novel CO2 heat pumps can reach a water inlet temperature of 40 C and a water outlet temperature of 95 C. The systems have purportedly a combined coefficient of performance of up to 5.56.
India eyes self-reliance in battery cells with lithium recycling push
India could achieve self-reliance in battery cell manufacturing by domestically recycling lithium and reusing it in batteries, an Indian government official claimed this week at a battery manufacturing conference in in New Delhi.
TOPCon IP battle intensifies with Qcells launching infringement notices
Qcells has launched an intellectual property (IP) dispute over alleged unauthorized use of its patented laser-enhanced contact opening (LECO) tech in tunnel oxide passivated contact (TOPCon) solar cells. The case underscores rising tensions in the PV industry over TOPCon patents.
Swiss company Synhelion to start producing solar fuels in Spain in 2027
The company has signed a long-term purchase agreement for solar gasoline with AMAG Group, which will purchase 50,000 liters of solar gasoline per year from Synhelion’s RISE plant in Spain starting in 2027.
UAE, Italy, Albania announce cross-border green energy cooperation plans
The United Arab Emirates, Italy, and Albania plan to cooperate on gigawatt-scale renewable projects in Albania and a cross-border transmission link to deliver power to Italy.
Wind tunnel tests show spacing between panels is key to reduce soiling
Scientists have placed four PV panels in a 21-meter wind tunnel and run different tests regarding tilt angles, mounting height, spacing, and incoming flow direction. They found that when the spacing between panels exceeds twice the panel height, the mutual influence on dust deposition becomes negligible.
Open-source dataset for rooftop PV generation in urban environments
A group of scientists has developed an open-source dataset comprising three years’ worth of data from Hong Kong’s largest behind-the-meter rooftop solar power project. Power generation was collected at 5-minute intervals, and meteorological data at 1-minute.
U.S. scientists building magnetocaloric heat pump with high system power density
Developed at the U. S. Ames National Laboratory, the novel magnetocaloric heat pump utilizes gadolinium as the working medium and reportedly matches current vapor-compression heat pumps for weight, cost, and performance. The system is based on a packed-particle bed active magnetic regenerator, a magnetic source composed of permanent magnets and high permeability magnetic steel.
Solis releases three-phase string C&I inverters with fuseless design
The Chinese inverter said its new inverters have an MPPT current of up to 54 A and support more than a 150% DC/AC ratio. The new products also feature a maximum efficiency of 98.8% and a European efficiency rate of 98.3%.
European consortium develops perovskite-CIGS tandem modules for distributed solar PV
A European project aims to develop flexible tandem perovskite-CIGS solar technology to make 25%-efficient 100 cm2 modules with a variety of substrates for decentralized solar PV applications. The project entails using processes that are scalable for roll-to-roll production.
