Qcells says it will use Lumet’s fine-line metallization technology for its solar cells, for higher efficiency and lower production costs. May 30, 2024 Patrick Jowett Metallized silicon solar cellsImage: LumetQcells has agreed to deploy Israeli-headquartered Lumet’s ultra-fine metallization technology for its solar cell line.The metallization step, in which conductive silver fingers are screen-printed onto the surface of solar cells, is widely considered to be the largest expense in cell production. Efforts to reduce finger width from the industry standard of 20 microns are aimed at reducing silver consumption, cost and light shadow, while also increasing efficiency.Lumet says its technology can…

An independent public classical radio station in Austin, Texas, is adding solar power to save on energy costs and boost its sustainability efforts.KMFA Classical 89.5 collaborated with local ownership Ash solar energy to install an 89.64 kWdc system consisting of 166 solar panels on the roof, the maximum number allowed within the city code. Once operational, the solar panel will offset an estimated 133 MWh of electricity consumption annually.In addition to the rooftop solar system, KMFA’s capital investment also includes the installation of four EV charging stations in the company’s parking lot, all of which will be equipped with universal…

The California Public Utilities Commission released a report revised proposal for decision on the state’s community solar program on May 28, after multiple votes on the previous proposal. The CPUC is set for voting about the new PD next Thursday, May 30. A diverse group of organizations, including the Coalition for Community Solar Access, The Utility Reform Network and the Coalition of California Utility Employees, previously proposed a community solar program to the CPUC, centered around a Net Value Billing Tariff (NVBT). This rate program would have compensated subscribers of community solar projects up to 5 MWAC based on the…

UIS Technologies has commissioned polyurethane (PU) recoating and reprofiling solutions for wire guide rollers (WGRs) at Adani’s 2 GW solar ingot wafer plant in Gujarat, India. May 30, 2024 Uma Gupta By pv magazine IndiaUIS Technologies, a precision technology company based in Penang, Malaysia, has announced the commissioning of its PU solutions for recoating and reprofiling of WGRs at Adani’s 2 GW solar ingot wafer plant in Mundra, Gujarat, India.WGRs play a crucial role in the silicon ingot cutting phase of the silicon ingot to wafer manufacturing processes. The precise grooving of these rollers has a significant impact on the…

The new heat pump concept combines solar energy with chemical storage and reportedly uses 75% less electricity than conventional heat pumps. The system uses a battery and a heat storage tank that can be used separately or simultaneously depending on outdoor conditions. May 30, 2024 Emiliano BelliniResearchers from Chiba University in Japan have designed a heat pump system that integrates photovoltaic-thermal (PVT) energy with chemical storage, involving an exothermic reaction that releases heat and an endothermic reaction that stores heat.The proposed solar chemical heat pump (SCHP) is intended to heat and cool buildings and can reportedly use 75% less electricity…

Singapore and Ghana signed a carbon credit agreement on May 27, 2024, an important step towards global environmental sustainability. This deal allows companies in Singapore to offset part of their carbon tax by investing in certified carbon reduction projects in Ghana. Unlocking the details of the Singapore-Ghana Carbon Credits Agreement The Carbon Credit Agreement, officially known as the “Implementation agreement” promotes cooperation under Article 6 of the Paris Agreement. Grace Fu, Singapore’s Minister for Sustainability and Environment and Minister for Trade Relations, and Ghana’s Minister for Environment, Science, Technology and Innovation, Ophelia Hayford, were responsible for the signing. The main…

EDP ​​Renewables North America has announced the completion of the new Crooked Lake Solar Park near Blytheville in Mississippi County, Arkansas. The 175 MW project will generate enough energy to power the equivalent of 30,000 Arkansas homes annually. Crooked Lake Solar Park will directly support Arkansas’ electric grid and is built on land leased by local landowners who recognize the benefits of hosting a solar project and believe in the economic impact it will have on the city and the greater province, complementing the area’s agricultural heritage. Crooked Lake will support more than 330 construction jobs and six permanent jobs…
