Solis unveils 75–125 kW hybrid inverter for C&I solar
The Chinese manufacturer said its new inverters can deliver 160% overload for 200 ms in off-grid mode, ensuring stable startup of heavy loads. The IP66-rated products feature a maximum efficiency of 97.6% and a European efficiency of 97.2%.
Researchers present inverter-based dust monitoring method for rooftop solar
Researchers in China have developed a dust monitoring technique that relies solely on the existing hardware resources of inverters, without requiring extra sensors or meteorological data. Tests on existing rooftop PV arrays demonstrated an accuracy exceeding 96%.
IEA says cost of capital for solar remains high in Southeast Asia
The International Energy Agency says the cost of capital for solar remains higher in Southeast Asian countries than it does in other emerging and developing economies.
Researchers test solar panel cooling using stagnant water layer
Researchers have developed a stagnant water layer cooling concept and tested it using seawater, tap water, and desalinated water. The panel temperature decreased by up to 8.2 °C, while power output increased by approximately 28%.
Solar module prices to rise 9% in Q4, says Wood Mackenzie
Wood Mackenzie says module prices will climb as China ends export rebates and consolidates polysilicon production.
Novel fluorine recovery method promises polymer recycling benefits
Researchers have developed a novel defluorination method to dispose of PTFE, used in solar componentry and electric cable coating, that converts its constituent fluorine compounds and could enable eco-friendly polymer recycling.
South Korea hit by ‘digital Pearl Harbor’ as aging battery sparks data centre fire
A lithium-ion battery explosion at a national data centre in South Korea disabled hundreds of government systems, highlighting the vulnerabilities of a highly centralised digital infrastructure.
Risen presents 475 W TOPCon solar panel with 23.8% efficiency
Chinese solar module maker Risen Energy has introduced a 475 W bifacial solar module with a power conversion efficiency of 23.8% to the Australian market, targeting the rooftop market.
New algorithms boost dual-axis solar tracker performance
Researchers in Australia and India have developed two solar tracker optimisation techniques that can purportedly increase power generation by up to 54.36% when combined. One uses a light sensor and the other relies on data from GPS and a real-time clock.
Solar megaproject’s Singapore exports has social licence work to do: research
The proposed Australia-Asia PowerLink, a Northern Territory 12,000 hectare solar megaproject, has received a thumbs up from 89% of survey respondents who say they support the project’s construction, but remain skeptical about its Singapore exports.
