PV module fault diagnosis uses convolutional neural network
Researchers in China have created a dataset of various PV faults and normalized it to accommodate different array sizes and typologies. After testing the new approach in combination with the 1D-CNN machine learning technique under different conditions, they found an accuracy of more than 99%.
Power Roll tests perovskite solar panels outdoors
Power Roll, a UK developer of perovskite solar technology, has begun outdoor testing of its 600 mm x 400 mm flexible modules.
Cooling PV inverters with skived fin heat sink
Researchers in Turkey tested a novel heat sink design to cool insulated gate bipolar transistor (IGBT) arrays in solar inverters. They found that it reduced module temperatures by more than 6 C in lab experiments.
Norway deploys 49 MW of solar in H1
Norway’s solar deployment rate slowed in the first half of 2025 compared to the previous two years, as the government introduced new regulations targeting medium-sized commercial systems.
Mito Solar launches new range of colored modules for yachts, cars
Dutch specialty module manufacturer Mito Solar now offers PV modules in a wide range of colors for yachting and mobility applications. The colors are enabled by a front-side encapsulant made of thermoplastic polyolefin (TPO).
PV-thermal energy with heat pumps, aquifer thermal storage in buildings
Researchers in the Netherlands have simulated a residential energy system combining PV, solar thermal, and PV-thermal panels with aquifer thermal energy storage and a heat pump, achieving a seasonal coefficient of performance of seven across five buildings.
PV installers must act as US solar tax credit phase-out looms
Aurora Solar says most US homeowners are unaware of the urgency created by the One Big Beautiful Bill’s (OBBB) phase-out of the 30% solar tax credit, underscoring the need for installers to educate consumers, cut soft costs, and prioritize transparency.
Using Sudoku to improve power yield in PV systems under partial shading
Indian researchers have developed a Sudoku-based technique to reduce power losses in PV systems operating under partial shading. They claim the method increases energy efficiency and revenue generation more than conventional reconfiguration techniques.
Solitek launches anti-glare black bifacial solar modules
Lithuania’s Solitek has launched full-black 425 W bifacial solar modules with matte, satin-textured glass for glare-sensitive sites such as airports, road barriers, and buildings.
Sun King secures $156 million to expand off-grid solar in Kenya
Sun King has secured a $156 million deal backed by Kenyan banks and international development finance institutions to expand off-grid solar access in Kenya, financing the purchase of about 1.4 million solar products and smartphones.
