Solar productivity negatively impacted by emissions and aerosols, study finds

A study by engineers at UNSW, published in the Renewable Energy journal, shows that aerosols and greenhouse gas emissions reduce the productivity of photovoltaic installations and that this differs according to the global region.

Physics-based model to predict soiling losses in bifacial solar modules

Scientists in India have developed a novel way to predict soiling accumulation on bifacial modules. Their approach considers dust deposition, rebound, and resuspension phenomena.

The impact of soiling on PV module transmittance

A European group has looked into the soiling impact on PV modules in Oman. They have collected 60 samples, based on season, month and tilt angles.

All antireflective solar module coating techs at a glance

Scientists in the United Kingdom have investigated the durability and performance of all antireflecting coatings for solar modules and said further work is needed to improve industry standards. Their review addresses single-layer and multi-layer techniques and provides insight on their costs and viability.

How to successfully implement robotics and automation in solar PV plants

Solar projects in India face many challenges due to the complex terrain of the solar plants, making the proper implementation of robotics and automation quite a challenge.

Why do solar power plants work inefficiently?

When choosing a solar power plant, individuals and businesses pay the most attention to its power – after all, this will determine how much electricity will be produced. Other equipment, systems and sensors that allow monitoring and analysis of the operation of the power plant are often underestimated. But they shouldn’t be: the solar power plant will be used for several decades, so various failures and poor-quality monitoring can have a significant impact on the efficiency of electricity production.

Have your say on the future of automation in solar O&M

Cost efficiency while maximizing power output is the name of the game in solar project development and asset management. And the automation of the provision of utility scale solar operations and maintenance (O&M) is fast becoming one of the most compelling opportunities. Help shape the future of automation in solar O&M by completing this first-of-its kind survey.

The long read: Dealing with dust

Sand and dust are a PV plant operator’s worst nightmare. Performance losses due to soiling, or “the dust effect,” are a cause for innovation among O&M providers, particularly in dry and dusty regions that are otherwise ideal locations for large-scale solar installations. Yazeed Al-Mousa examines the latest robotic cleaning solutions, as well as the software and sensors that help plant operators with the tricky economic decision of when to actually start cleaning.

Handheld dry-cleaning tool for solar modules 

The handheld, cordless cleaning tool is a cost-effective and efficient alternative to automated cleaning robots that are usually limited in operation by panel inclination. 


The long read: The impact of dust on solar panels matters

Anil Kottantharayil currently leads the Centre for Research in Nanotechnology and Science, as well as the Sophisticated Analytical Instrument Facility, at the Indian Institute of Technology (IIT) Bombay. He works on high-efficiency crystalline silicon solar cells, the impact of dust on solar panels, and the long-term reliability of photovoltaic modules.
