Enhancing Solar Panel Dust Detection with AI: Tackling Dataset Imbalance

Leave a Comment / News /

At Sunlink, we understand that even small amounts of dust on photovoltaic (PV) modules can significantly reduce energy output. Accurate and timely detection of dust accumulation is therefore critical for optimizing cleaning schedules and maximizing the return on investment for solar installations. However, developing robust AI models for dust detection comes with a hidden challenge:

How to avoid ‘long tail’ effects in large-scale PV plants

Leave a Comment / News /

A group of researchers from University of New South Wales (UNSW) studied the “long tail” phenomenon in large-scale photovoltaic plants and found that about 20% of the solar modules used on the field degrade much faster than expected. The “long tail” occurs when a significant number of modules in the same facility underperform relative to expectations, creating

South Korea introduces standards for photovoltaic-thermal modules

Leave a Comment / News /

South Korea’s National Institute of Technology and Standards (KATS) has introduced new national standards for photovoltaic-thermal (PVT) solar panels. The government-run agency said the new standards apply to modules that combine photovoltaic and solar thermal technologies in a single device, noting that separate standards for each technology already exist. “This regulatory improvement system accelerates the

How to assess bifacial PV system performance on sloped terrains

Leave a Comment / News /

Researchers from Bangladesh’s East West University have developed a novel method for analyzing bifacial PV systems on sloped terrains. The novel technique is a precursor formulation that is then inserted into existing PV simulation models that do not account for hilly solar farms. “A complete reformulation for bifacials would need a lot of effort, so instead we
