New deep learning tech for PV inverter fault diagnosis
A team of scientists at Georgia Southern University has combined both spatial and temporal attention mechanisms to develop a new approach for PV inverter fault detection. Training the new method on a dataset created in MATLAB/Simulink, the group has compared it to a series of other data-driven and statistical-based methods and has found accuracy reached 97.35%.
Clean energy transition requires more comprehensive local planning, study says
Local energy initiatives have increased at the local level, but researchers say more focus on addressing spatial planning and economic benefits is needed in the renewable energy transition.
Inside perovskite solar cell durability and performance testing
Accurately measuring the performance of perovskite solar cells and modules requires significant modifications to long-established testing standards used in silicon PV. Researchers are settling on methods that rely on up to several minutes of constant light exposure and other time-consuming procedures. These may be fine for the laboratory setting, but those looking to produce this technology at scale need standardized methods that can characterize cells and modules at a much faster rate.
Solaires Entreprises ships indoor perovskite PV modules to first customer
Solaires Enterprises, a Canadian perovskite startup, has begun supplying indoor PV modules for integration into sensor devices, marking its first commercial shipment.
Net metering causes less than one dollar cost shift to most ratepayers, study says
With many states seeking to replace net metering with alternative compensation that pays solar owners less for their excess electricity, the National Renewable Energy Laboratory launched a qualitative study to find the truth behind the alleged cross subsidization of solar customers by non solar customers.
Rooftop solar, battery storage could offer a lifeline in energy insecurity
A study explored the relationship between energy insecurity and severe energy-limiting behaviors to lower bills, and how interventions with rooftop solar and energy storage systems can allow recipients to live safely and comfortably in their homes while also being able to afford necessities like food and medicine.
How agrivoltaics can alleviate Washington’s mounting agricultural, energy pressures
An in-depth study looked at the varying facets within Washington’s agriculture industry to determine how and where agrivoltaics can be best implemented to help meet the state’s energy needs and provide financial support to the state’s agriculture industry.
Washington farmers divided over solar on farmland, agrivoltaics largely unknown
A research survey of farmers and ranchers across Washington state offers insight into how developers can best approach solar development in The Evergreen State.
Colocating solar with Washington’s most valuable crop
When designed right, colocating apple orchards and solar installations can be not only economically beneficial for the landowner, but produce a higher rate of marketable apples.
Agrivoltaic shading, full-sun fields gives farmers the power to pivot
Research conducted at the oldest agrivoltaic research site in the United States found year-to-year weather variability impacts agrivoltaic crop production, emphasizing the importance in conducting studies across multiple years.
