Technology and R&D

The new three-phase hybrid inverter series includes five versions with power ratings of 6 kW to 15 kW. They feature efficiencies of up to 98.2% and a maximum input voltage of 1,000 V.

Scientists in the Emirates have conceived a new space vector pulse width modulation method that reportedly reduces switching losses and increase efficiency in three-phase photovoltaic inverters. The proposed technique was found to have a higher efficiency, while providng lower common-mode voltage, leakage current and total harmonic distortion compared to traditional pulse width modulation approaches.

Chinese manufacturer Sigenergy has launched a new modular energy storage solution that combines a hybrid inverter and battery pack with a built-in energy management system. The inverter series offers a range of power options from 50 kW to 110 kW.

The latest test method addresses the fire propagation behavior of a residential battery energy storage system if a thermal runaway propagation event leading to an internal fire were to occur during the system’s lifetime.

A German research team has developed a new technique to recover and reuse methylammonium lead iodide (MAPbI3) from perovskite solar cells via solvent extraction. Such recycling method can reportedly save up to 61% costs in the lab and industrial manufacturing.

Using a surrogate model for finite element analysis, the scientists have designed an aluminum frame for bifacial modules that reportedly minimizes deflection and production costs, without adding too much weight. Deflection can lead to cracking or delamination of ribbons inside the module, resulting in an increase number of damaged cells.

Agri-Light has launched its first pilot agrivoltaic project, using a two-axis solar installation on a rail system to move solar panels horizontally above a vineyard in the Negev Desert. The results are due this summer, and the company plans to build commercial projects in Israel and Spain next year.

A group of scientists from the UAE-based energy utility has developed a new method to conduct I-V curve measurements without transporting the solar modules to laboratories for detailed analysis. The proposed Suns-Vmp approach reportedly offers a “very low” average root mean square error between the simulated and the real I-V curves.

A global team of researchers – lead by Monash University in Melbourne, Australia – says it has made a breakthrough that could make perovskite solar cells more reliable and efficient.

Researchers in China have developed a floating structure for offshore PV that reportedly offers improved stability and dynamic responses compared to conventional semi-submerged floating designs. The floating structure consists of pontoon-truss platform composed of four pontoons and a steel truss connected by soft ropes.
