JinkoSolar presents 475 W TOPCon dual-glass solar panel with 23.77% efficiency
The Chinese manufacturer said its new IEC 61215-certified rooftop PV module relies on a 30 mm aluminum frame and dual-glass construction that reportedly help it withstand extreme snow loads and wind pressure.
Africa’s solar capacity surpasses 20 GW
Africa’s solar capacity has exceeded 20 GW, with more than 10 GW of projects under construction, led by utility-scale solar, which represents 70% of ongoing development, according to the Africa Solar Industry Association (AFSIA).
Carrier launches new heat pump for residential, light commercial use
Carrier, a US-based heating solutions provider, has introduced a new heat pump system featuring a cooling seasonal energy efficiency rating (SEER2) of up to 29.7 and a heating seasonal performance factor (HSPF2) of up to 12.2.
Ireland to meet 2030 target of 8 GW solar, claims Wood MacKenzie
Wood MacKenzie predicts that Ireland will meet its 8 GW 2030 solar target but wind, heat pumps, and electric vehicles (EVs) are all lagging behind theirs. Ireland’s current installed solar capacity is just under 2 GW, but this could be increased thanks to favorable policy, grid investments, and energy storage.
Slovenia deploys 85 MW of solar in H1
Slovenia installed 85 MW of solar in the first half of 2025, driven by growth in commercial and industrial (C&I) projects and utility-scale installations. The lowest total in four years reflects a sharp decline in residential installations, despite continued subsidies for residential hybrid systems.
California high court orders review of rooftop solar incentive cuts
The California Supreme Court has ordered the state appeals court to reexamine its decision to defer to the California Public Utilities Commission (CPUC) over a controversial cut to rooftop solar incentives. The net energy metering 3.0 ruling led to a crash in California’s once-thriving rooftop solar market and put clean energy procurement goals in jeopardy.
Photovoltaic-thermal solar air heater based on PCM cylinders, air convection
Researchers in Malaysia designed a photovoltaic-thermal system that can be used in solar drying, space heating, rooftop systems, and off-grid thermal applications. It relies on a double-pass cooling technique based on air convection and phase change material that can reportedly increase PV efficiency from 7% to 9% and thermal efficiency by 31.45%.
Netherlands installs 4.32 GW of solar in 2024
The Netherlands installed 4.32 GW of solar capacity in 2024, bringing its cumulative total to 28.62 GW by year-end, according to official data.
How long do residential solar batteries last?
Multiple factors affect lifespan of a residential battery energy storage system. We examine the life of batteries in Part 3 of our series.
Quebec to offer rebates for home, commercial solar
Hydro-Québec says it will offer financial aid to residential and business customers deploying solar in the Canadian province from next year, with CAN 1,000 ($726.28) available for each installed kilowatt.
