Freesuns brings PV to Swiss heritage buildings
Swiss module manufacturer Freesuns has installed 33,300 of its solar roof tiles on three historical buildings in the Swiss town of Neuchâtel.
Norwegian startup combines solar with EV recharging, energy management
Norway-based Evert said its new solution can simplify installing solar PV, energy management, and electric vehicle charging by combining multiple devices into one unit bundled with software. It is made for the European residential and commercial markets, and expected to be available in mid 2025.
Germany adds 960 MW of solar in September
Germany installed 960 MW of solar in September, bringing its cumulative PV capacity to more than 94.52 GW.
TNO researchers build world’s first bifacial PV window
The new multifunctional PV window concept aims to produce electricity while providing over-heating protection for better indoor thermal and visual comfort. It consists of an insulating glazing unit with bifacial crystalline silicon solar cells strips and embedded venetian blinds that act as reflectors for the rear side of the cells.
PV fault detection method based on deep learning of aerial images
Conceived an international research group, the proposed model uses the convolutional neural network (CNN) architecture U-Net for image segmentation and the the CNN architecture InceptionV3-Net for fault classification.
Redback presents home battery, inverter range
Battery and inverter manufacturer Redback Technologies has bounced back from a tumultuous start to the year – including a short stint in voluntary administration – with the launch of a new range of solar and energy storage products.
Dutch PV sector calls for consumption incentives as end of net metering looms
Dutch trade body Holland Solar is urging the new Dutch government to introduce self-consumption incentives for batteries, boiler tanks, and heat pumps used in combination with PV systems, as the country plans to phase out net metering by 2027.
Japan’s oldest PV system gets refurbished
Tokyo-based startup Girasol Energy and the enterprise bureau of Japan’s Yamanashi prefecture have repowered Japan’s oldest PV system, a 100 kW array built in 1993. The project aimed to partially replace the original 13.3% efficient solar modules, offering an alternative to dismantling and recycling the system’s components.
Gstar introduces 440 W TOPCon solar module with framless design
The Singapore-based manufacturer said its new panel can achieve self-cleaning through rainwater thanks to its frameless design. The new product features an operating temperature coefficient of -0.30% per C and an efficiency ranging from 21.51% to 22.53%.
Duffing oscillator can increase low output voltages in PV systems at dawn, sunset
Scientists have utilized a device based on the Duffing oscillator to solve the problem of PV systems’ low efficiency at low input voltages at dawn and sunset. Its performance was reportedly better than that of a conventional DC-DC boost converter in amplifying weak input voltages.
