Optimization strategy for PV-powered EV charging stations relying on V2G
Scientists in China have created an optimization technique for an electric vehicle charging station that uses PV, battery storage, and a vehicle-to-grid operation. Considering the uncertainty of PV generation and the randomness of EV load, the system uses two-level optimization, day-ahead and intra-day.
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.

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.
Making the business case for solar-plus-storage with heat-pumps in Japan
A Japanese research team has evaluated the affordability of photovoltaic-battery systems featuring heat-pump water heaters and air conditioning units across nine regions of Japan. They analyzed three price policies and two loan types, identifiying a tradeoff between net demand and cost according to the capacity of the solar-plus-storage system.

PV-powered thermal distillation device with self-cleaning, cooling
Scientists in Hungary have built a prototype of a thermal distillation device, supported by PV power. The PV panels use an IoT component that self-cleans when dust is detected and cools itself when the temperatures are too high. The system achieved a daily freshwater yield of 6.1 L/m2â‹…day.
Floating PV system with ring-like floater geometry
Scientists in China have investigated the hydrodynamic performance of a novel modular floating photovoltaic system. They did so using a novel hybrid approach, which integrates viscous-flow effects from computational fluid dynamics into a potential-flow solver. They analyzed the new system with varying numbers of panels, either in a single chain or a parallel configuration.
Chinese Academy of Sciences developing thermoacoustic heat pump for industrial applications
The researchers developed a heat-driven thermoacoustic heat pump that can purportedly achieve a temperature lift of 125 C. It uses a thermoacoustic heat pump to stably release the heat from the engine unit. The system also includes a thermoacoustic engine unit and acoustic resonators.
