Pressurized water cleaning can improve PV generation efficiency by 10%
Researchers in China have investigated the dust-scaling process and various water-based cleaning methods to optimize maintenance strategies for enhanced safety and efficiency in PV systems.
PV-powered electric vehicles can have up to 30% higher range
A European research team has installed solar panels on a light commercial electric vehicle and has tested their performance for four months. The vehicle was able to extend the range by 530 km, although not all panels contributed equally. System efficiency was measured at up to 66%.
New fire safety testing procedure for PV systems deployed in flat roofs
The Slovenian National Building and Civil Engineering Institute (ZAG) has introduced a fire safety test that simulates a fire starting on the roof membrane beneath a PV system. The researchers noted the importance of realistic construction methods, including factors such as anchors, adhesives, membrane welding, and ballast use.
PV energy forecasting based on genetic algorithms, dynamic neural network
Scientists in Spain have used genetic algorithms to optimize a feedforward artificial neural network for the prediction of energy generation of PV systems. Genetic algorithms use “parents” and “offspring” solutions to achieve better results in subsequent generations.”
UL Solutions expands testing for heat pumps
UL Solutions says it will expand heat pump testing at its facilities in Texas and Italy to meet rising demand in the heating, ventilation, and air conditioning (HVAC) industry.
Aluminum foils can reduce temperature in double-glass PV modules by 6 C
Scientists in China placed a 0.5 mm thick aluminum foil between the solar cell and the EVA, and between the EVA and the glass layer. The two experimental modules were compared to a reference module and were found to dissipate heat and increase the in-plane temperature uniformity.
Slovenia allocates €16 million for solar energy communities
Slovenia has set aside €16 million ($16.7 million) to support solar energy communities, requiring projects to include at least 100 kW of PV capacity, with or without storage. The program will run until 2027.
UN refugee agency to power most of its offices with PV
The United Nations High Commissioner for Refugees (UNHCR) has revealed plans to install solar systems in 18 offices by 2025, aiming to cut emissions and reduce reliance on diesel.
Testing shows BIPV using patterned glass performs better than expected
Scientists have compared conventional PV modules to self-made BIPV panels with thicker, patterned glass. They tested them both under standard conditions and outdoors under Korean summer conditions. Yield was found to be only 0.5% lower in the textured BIPV module.
Field manual for off-grid residential PV in remote communities
A research team has constructed a technical field audit among users of solar systems in remote communities in Ghana and has identified some recurring technical issues. Based on the collected data, the scientists have also developed a practical field manual.
