How to size PV systems and batteries
Experts from Fonte Solar, Huawei, and Greener have exchanged solar-plus-storage tips, insights, and case studies at the invitation of pv magazine. In a panel at Intersolar South America 2025, they highlighted the need to understand consumption profiles and customer needs, as well as the technology’s limitations and potential.
Weathered PV backsheets have 46% faster flame spread than unweathered counterparts
Researchers in Singapore have accelerated the weathering of PV backsheets and investigated their flame spread behavior at different intervals. After 6 weeks, they found that weathered PV backsheets show 46% faster flame spread than unwearthered ones. They have also highlighted that current safety standards fail to account for long-term degradation.
All back-contact perovskite solar cell designs at a glance
Scientists from Japan, Saudi Arabia and the United States have investigated existing back-contact perovskite solar cell architectures and have proposed a strategy to help reach commercial production.
New hail test aims to more accurately measure solar panel resilience
A new test curve for determining solar panels’ breaking point from hail uses a broader spectrum of impact energies and testing products.
Finnish glass maker offers PV systems integrated into glass balcony parapets
Finland-based Lumon has integrated balcony PV modules into a glass parapet, maintaining the facade’s appearance without visible technical components. The first project using the product has already been completed in Finland.
Freen launches scalable sodium-ion battery storage
The Estonian home and commercial storage systems come in low- and high-voltage models. The high-voltage option can scale to ten modules, for 100.8 kWh, and a six-module, low-voltage version to 45 kWh.
Chinese manufacturer plans solar glass factory in Algeria
China’s Kibing Group is looking to develop a solar glass manufacturing facility in Algeria with an annual production capacity of 1.53 million tonnes.
Finetuning 2D Dion-Jacobson perovskites for photovoltaic applications
Canadian and U.S. researchers have investigated applying pressure to a 2D hybrid organic-inorganic perovskite to tune the optical and electronic properties to suit photovoltaic applications, light emitting diodes or other semiconductor devices.
Huasun achieves 34.02% efficiency for perovskite-heterojunction solar cell
The Chinese manufacturer said the result was achieved thanks to new perovskite crystallization additives and high-mobility carrier transport layer materials.
New deep learning tech for PV inverter fault diagnosis
A team of scientists in the United States 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%.
