Startup unveils zinc-polyiodide redox flow battery with energy density of 320 Wh/L
BESSt announced that its new redox flow battery technology delivers 20 times the energy density of conventional vanadium flow storage systems. The battery is based on a zinc–polyiodide redox flow chemistry developed by the Pacific Northwest National Laboratory. From ESS News US-based startup BESSt has launched a new redox flow battery technology that reportedly achieves 20 […]
Voltage Energy releases two wiring solutions for solar projects
The US-based electrical balance of systems provider stated its new products are designed for utility-scale projects and the mid-capacity range. Both systems are IP68-tested. From pv magazine Global North Carolina’s provider of electrical balance of systems (EBOS), Voltage Energy, has launched two new pre-assembled wiring solutions for PV projects. The Lynx product is engineered for utility-scale […]
New control strategy for grid-forming inverters
Researchers in the United States have created a droop control strategy for grid-forming inverters that purportedly improves power system frequency stability. By using an exponential active power–frequency relationship, the novel technique optimizes the use of available headroom, reduces frequency deviations, and enhances overall grid resilience. Renewable energy resources using grid-forming inverters can actively regulate voltage […]
Community solar may have peaked in 2024, said Wood Mackenzie
Wood Mackenzie reported a 36% decline year over year for the first half of 2025 and forecasts 12% annual contraction through 2030. After a record year for installations in 2024, community solar dropped 36% year-over-year for the first half of 2025, said a report from Wood Mackenzie and the Coalition for Community Solar Access. The […]
Transforming existing solar arrays to microgrids could generate revenue for many customers
SolMicroGrid’s Kirk Edelman says the technology is there to be utilized if the tariffs – and Washington – will allow. Solar-powered microgrids have progressed from generators of electricity in isolated, off-grid locations to key infrastructure for delivering economic and resilient power. The widespread availability of lower cost battery storage has been a key driver in […]
Conventional C&I solar sales techniques are broken. Here’s how to fix them
For commercial & industrial solar, getting the initial “yes” is only half the battle. The real challenge is keeping momentum and closing multi-stakeholder deals that often stall for no clear reason. After decades of relying on traditional sales techniques, I realized that success in today’s long-cycle projects demands a fundamental shift from micromanagement to vision […]
IEA-PVPS warns soiling costs solar industry billions per year
The International Energy Agency’s Photovoltaic Power Systems Programme (IEA-PVPS) says dust, pollution, and debris on solar panels reduce output by 4% to 7% worldwide, costing the industry billions of euros annually and making tailored mitigation increasingly urgent. From pv magazine Global Soiling on solar installations costs the global solar industry annual revenue losses totaling billions of […]
Why California’s closed $2 billion solar plant is not a signal of industry failure
Beginning operations in 2014, the Ivanpah Solar plant in California cost $2.2 billion to build. It is now closing operations, but the plant’s closure is not an indication cost problems for the solar industry. Headlines have been circulating major news outlets around the impending closure of the Ivanpah Solar Power Facility, a $2.2 billion project […]
Freight costs steady after early September spike
Freight costs, which contribute towards the total cost of a solar installation, have fallen week-on-week on trade lines out of the Far East, helping to offset a price surge in the US-bound short-term market recorded at the start of September. From pv magazine Global Freight container shipping spot rates have declined week-on-week, with a spike […]
Western wildfires, storms cut solar gains in the West while Eastern US sees boost
In a new weekly update for pv magazine, Solcast, a DNV company, reports that trontal systems, widespread wildfires and an omega block pattern contributed to highly mixed irradiance anomalies across North America in September. Solar conditions underperformed in much of the West and Midwest, while the Northeast, South, and parts of Canada recorded a strong […]
