Quantifying uncertainty to produce more useful solar generation forecasts
Renewable energy firm PowerUQ advocates for the use of Uncertainty Quantification (UQ) in solar project analytics to combat the widespread issue of performance shortfalls. By incorporating a wider range of variables and providing probability scenarios like P50 and P90, UQ aims to make solar generation forecasts more useful and accurate over a project’s long lifespan.
Sodium-ion battery storage for ultra-low temperatures
U.S. researchers have developed a sodium-ion pouch cell that operates reliably at temperatures as low as –100 C. The battery was tested with simulated and real renewable energy sources, including wind and solar, and maintained stable performance in both laboratory and field conditions.
MIT researchers develop polymer film that could prevent solar panel corrosion
Engineers at the Massachusetts Institute of Technology say their polymer coating could be used to protect photovoltaic modules, due to its impermeability to gases. The team has demonstrated that a 60-nanometer-thick film can extend the lifetime of a perovskite crystal by several weeks.
‘It’s not a matter of sodium versus lithium, we need both’
A US research team has developed all-solid-state sodium batteries that retain performance down to subzero temperatures. The systems utilize a special chloride-based solid-electrolyte-coated cathode.
Open-access, modular monitoring platform for multi-year outdoor PV testing
A team of researchers in Canada has developed the Jericho Open Resistive Data Logger—an open-access photovoltaic (PV) monitoring platform that integrates data acquisition and processing hardware, a software framework, and a comprehensive sensor array. Designed primarily for agrivoltaic applications, the system has a total estimated cost of around $2,000.
In Virginia and New Jersey, solar and storage goals include surplus interconnection
Incoming governors in New Jersey and Virginia campaigned on broad clean energy platforms, while Advanced Energy United sees underused points of interconnection as the best solar and storage opportunity in Virginia.
Arkansas scientists build graphene-based solar cells than can charge supercapacitors
The solar cells combine multilayer graphene with silicon wafers, harvesting both solar and kinetic energy for continuous operation. Tests show the cells can autonomously power supercapacitors embedded in a temperature sensor.
Protecting the grid from extreme weather
IEC Standards help to make the grid more resilient as the impact of climate change intensifies.
New York awards $7 million for co-located solar and farming
Grant funds were administered by the New York State Energy Research and Development Authority (NYSERDA) to demonstrate the efficacy of agrivoltaics.
SolarEdge stock leaps on Q3 earnings, announces development of datacenter transformer
SolarEdge posted its third consecutive quarter of revenue growth and increased margins. The company announced a partnership with Infineon to produce solid-state transformers designed to power AI datacenters.
