Optimum tilt angle for PV systems ranging from 0° to 90°
A Slovak research team has developed a mathematical model for determining the optimum tilt angle of a solar system ranging from 0° to 90°. Their framework was tested on an experimental setup in Czechia and attained 93.9% accuracy in predicting the system’s energy balance.
Japan launches subsidies to accelerate perovskite solar deployment
The Japanese government has launched applications for two targeted funding schemes to accelerate deployment of lightweight perovskite solar tech and incentivize battery-backed systems that enhance grid resilience and economic viability.
Solar-Fabrik debuts back-contact solar module for residential, C&I applications
The German manufacturer said its full-black back-contact solar panel has a power conversion efficiency of up to 23.52%.
Stochastic optimization for PV-powered EV charging stations
Scientists have developed a new optimization approach that combines both day-ahead optimization and real-time optimization to improve operations of PV-driven EV charging stations. The framework is based on the autoregressive moving average and the Latin hypercube sampling models.
