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.


Where the ALMM listing requirement went wrong for India’s solar mission

The idea behind introducing the Approved List of Models and Manufacturers (ALMM) was to have a quality benchmark for solar modules. However, in its current form, it is more of a non-tariff barrier for foreign manufacturers and limits solar developers in terms of the choice of module wattage and make.  

Solar photovoltaic quality control and waste management in India 

As PV waste is set to rise rapidly in the coming decades, India needs to invest in efficient recycling technologies and devise a clear-cut policy for the safe disposal of PV waste. Guidelines for stringent quality checks and validation for both imported and locally produced solar panels are also needed to avoid early-loss solar waste.


Vikram Solar top PVEL performer for third consecutive year

The Indian solar manufacturer’s Series 6 module exceeded the international quality and performance benchmarks in testing under PV Evolution Labs’ Product Qualification Program.


Adani Solar top performer for fourth consecutive year

Adani Solar has received the Top Performer title for the fourth consecutive year for its high-efficiency modules by PVEL – the world’s largest resource of independent energy experts.


AI identifies a $14bn solar problem

How do you know when an inverter or module is under-performing? Monitoring services should shed light on problems but AI-driven digital asset manager Raycatch says much information is hidden behind a wall of “noise.” Breaking that wall with advanced data analysis could unlock billions of cost savings.

Mitsui Chemicals’ Gujarat lab now BIS-recognized for solar panel testing 

The Japanese firm, which established the lab in association with Germany-headquartered technical advisor PI Berlin, eventually plans to set up a diagnostic business for solar panels and power plants in India.

Waaree’s solar module testing lab becomes NABL accredited

The lab—located at Waaree’s factory in Gujarat—is the first such by an Indian module manufacturer and can perform more than 30 critical IEC tests.

Conformity assessment of solar PV panels in India

Quality of testing is equally important even as new test labs come up for solar modules. Proper equipment selection and frequent calibration of equipment are prerequisites to ensure the credibility of the test results.


The long read: In the long run

PV module makers are under growing pressure to increase the power output and longevity of their products, which leads in some cases to rapid changes in the technologies and materials they utilize. pv magazine recently sat down to speak with Kaushik Roy Choudhury and Mark Ma of DuPont Photovoltaic Solutions about the changing landscape for quality in solar PV materials.
