GoodWe debuts PV-driven heat pump water heaters
The Chinese manufacturer said their new residential heat pump water heaters deliver a coefficient of performance of up to 4.2, with a heating capacity ranging from 4.5 kW to 5 kW. The units are available with water tanks in 200 L, 300 L, and 500 L sizes.
Crystalline silicon vs. thin film at high latitudes
A four-year analysis conducted at a testing field in eastern Poland has shown that crystalline solar panels offer a stronger performance than thin-film panels at high latitudes. The tests revealed pronounced seasonal variability across all technologies, with thin-film modules showing markedly lower capacity factors than crystalline silicon, particularly in winter.
Wattlab deploys solar on multipurpose cargo vessel
The 79 kW system consists of 44 Solar Flatracks, which Wattlab describes as movable, stackable thin plates with integrated solar panels and inverters.
Mitsubishi presents new residential air-to-water heat pumps
Mitsubishi said that the two new products of its Hydrolution EZY series can produce domestic hot water up to 75 C when outdoor temperatures reach -25 C. The new systems have capacities of 6 kW and 7.1 kW.
World’s largest heat pump under development in Germany
The 162 MW project is being developed by German utility MVV Energie. The system will use water from the Rhine river as a heat source and is expected to generate heat with temperatures of up to 130 C.
South Korea introduces standards for photovoltaic-thermal modules
The country’s National Institute of Technology and Standards said the new standards apply to modules that combine photovoltaic and solar thermal technologies in a single device, noting that separate standards for each technology already exist.
Cambridge scientists discover photovoltaic properties in organic radical semiconductor
The researchers said their new discovery could open the way to the manufacturing of simpler solar panels made from a single material.
Fairland launches AI-based residential heat pump with coefficient of performance of 7
The Chinese manufacturer stated that its new heat pump system is the first on the market to achieve a coefficient of performance of 7. The product offers a nominal capacity ranging from 11 kW to 16 kW and uses propane as its refrigerant.
Longi reveals back-contact PV test results from offshore environments
The Chinese manufacturer claims back-contact Hi-MO 9 modules outperformed TOPCon counterparts in a six-month offshore test, showing higher power yield, better low-light performance, and lower operating temperatures.
Panasonic unveils new air-to-water heat pump for residential use
The Japanese electronics manufacturer said its new heat pump system is an ideal solution for centralised heating and domestic hot water installations. It offers a heating capacity of 9 kW to 16 kW and a seasonal coefficient of performance of up to 4.31 at low temperatures.
