LG launches new residential storage solution
LG has developed two versions of its new enblock E storage system, each with usable energy capacities of 12.4 kWh and 15.5 kWh. It says the two models, sized at 451 mm x 330 mm, can be easily deployed in small spaces.
The impact of climate-based PV panel degradation rates on inverters
New research from Belgium shows the importance of assessing inverter reliability by including climate-based PV panel degradation rates. The scientists found that, especially in hot and arid climates, PV inverters should be designed with parameters above the standard value.
How to combine residential heat pumps with PV, battery storage
New research from Germany’s Fraunhofer Institute for Solar Energy Systems (Fraunhofer ISE) has shown that combining rooftop PV systems with battery storage and heat pumps can improve heat pump efficiency while reducing reliance on grid electricity.
Sharp unveils 580 W TOPCon solar panel with 22.45% efficiency
Sharp’s new IEC61215- and IEC61730-certified solar panels have an operating temperature coefficient of -0.30% per C and a bifaciality factor of over 80%.
PV commissioning times up by 6 months over past 20 years, claim scientists
Scientists in Switzerland used project-level data from BloombergNEF to analyze completion times of renewable energy projects across 48 countries. They have found that average commissioning times have increased over the past two decades for all clean energy technologies.
Johnson Controls unveils water-to-water screw heat pump
Johnson Controls says its new screw heat pump is able to deliver high-temperature hot water as high as 176 F. The system reportedly has a combined coefficient of performance of 4.1.
Meyer Burger to cease PV module production in Germany
Meyer Burger, a Switzerland-based heterojunction cell and panel manufacturer, says it will stop making PV modules in Germany, but it will continue to produce solar cells in the country to support its panel production operations in the United States.
New solar tree design offers improved module cooling, lower shading losses
Researchers in Hungary have proposed to build photovoltaic trees with a significant distance between the solar panels. The proposed sunflower-shaped design reportedly reduces shading losses between the panels while improving cooling and heat dissipation.
Johnson Controls unveils water-to-water heat pump for commercial buildings
Johnson Controls says its new 1,406 kW compound centrifugal heat pump is able to deliver high-temperature hot water as high as 170.6 F. The system reportedly has a combined coefficient of performance of 4.9.
Using waste heat from PV panels to generate residential hot water
Scientists in the United States has developed a new photovoltaic-thermal system design that utilizes parallel water pipes as a cooling system to reduce the operating temperature of photovoltaic panels. The waste heat generated by this process is then used to generate domestic hot water.
