Coldplay, Kardinia Energy roll out printed solar during concert at Stanford Stadium
The rollout marks one of the largest live-event deployments of mobile solar today and offers a high-profile test for organic, ink-based photovoltaics.
Carrier debuts residential heat pump for cold climates
The U.S. heating specialist said its new heat pump system can operate “reliably” at -30 C and achieve 100% heating capacity at -17 C, with full cooling capacity being achievable at 50 C.
US utility-scale solar falls 30% to 4.4 GW in Q1
The United States installed 4.4 GW of utility-scale solar and a record 1.6 GW of grid-scale energy storage in the first three months of 2025, according to the American Clean Power Association. Solar installations declined about 30% from the previous quarter.
GE Appliances unveils residential hybrid heat pump water heater
The U.S. manufacturer said its new heat pump water heater can provide up to 60% more hot water than standard electric water heaters. The system is available in 240 V and 120 V options and with a capacity ranging from 160 L to 190 L.
Heliene expands solar module capacity with new 500 MW Minnesota plant
Heliene has opened a 500 MW solar module manufacturing line in Rogers, Minnesota, bringing its total US capacity to 1.3 GW. The facility has been operational since April.
Element Resources to build hydrogen plant with solar, storage in California
Element Resources plans to build North America’s largest hydrogen plant in California, using solar and battery storage to enable round-the-clock production.
Tariffs could drive US solar, storage costs up 50%
A recent Wood Mackenzie report examines two possible tariff scenarios and concludes that costs will skyrocket for both utility-scale solar development and battery energy storage systems.
US adds 7.4 GW of clean power in Q1 2025, led by solar and storage
The United States also installed a record 1.6 GW of grid-scale energy storage in the first quarter of 2025, according to a report from the American Clean Power Association (ACP).
Deploying floating PV on mine pit lakes, tailings ponds
Researchers in South Korea have conducted a literature review on recorded cases of floating PV plants placed on mine pit lakes and tailings ponds, both of which are byproducts of the mining industry. Looking at more than dozens of cases, they have concluded that mine pit lakes generally provide more stable environments for deployment.
U.S. scientists build antimony sulfide solar cell with 7.69% efficiency
Researchers at University of Toledo produced antimony sulfide (Sb2S3) thin film solar cells with 7.69% power conversion efficiency after determining optimal hydrothermal deposition, post annealing, and light soaking conditions. Stability tests showed more than 95% of initial efficiency after ten months.
