Next Energy said its 101.6 cm x 152.4 cm laminated transparent power-generating windows were produced with its pilot production line.

A Chinese research group has created a novel method to calculate city-scale rooftop PV potential not only based on roof areas but also including installation parameters and economic feasibility. The novel methodology was demonstrated in Nanjing, east China, and was found to be superior to conventional methods when it comes to estimating planned capacity.

Scientists in Tunisia have investigated the impact of PV panel tilt and water quality on green hydrogen production and have found that, with a variable orientation PV panel, the hydrogen generator could reach an efficiency ranging from 32% to 62% using demineralized water and 45% to 65% with distilled water.

A German research team has investigated the feasibility of a large-scale PV-powered seawater reverse osmosis desalination plant in Jordan and has found that keeping the concentrate flow constant is the most appropriate desalination operating mode.

Researchers in China have investigated the effect of the overhead height and tilt angle on thermal and energy-saving performance of photovoltaic roof and have found that the comprehensive energy-saving efficiency of parallel overhead photovoltaic roofs are optimal in summer and the worst in winter.

Developed by a research team including experts from Australian specialist Clearvue, the new PV windows were also able to reduce water usage in a greenhouse by 29%. The group believes that a fully glazed solar greenhouse could offset up to 100% of the energy consumption in worldwide locations by using adaptable and efficient temperature control techniques.

A before-after-control-impact study conducted at six French lakes for three years has revealed that PV coverage decreases water temperature by 1.2 C on average. The reduction in water temperature also occurred in areas of the lakes that were not covered with modules.

Scientists have conducted an analysis of 20 years of academic publications about PV-powered electric cooking and have found interest in the field peaked in 2021-2022 in both developing and developed countries. They have also outlined some potential future developments.

The Fraunhofer ISE has designed a novel method for assessing the potential of low-temperature heat sources for large-scale heat pumps. The five-step process was tested on the German city of Fellbach, enabling the identification of heat sources with LCOH lower than €0.1/kWh.

The Danish Energy Agency has developed an online tool to assess rooftop solar potential, using laser scan data and building registrar information. The solution does not assess the economics of projects.
