Maharashtra (473 MW), Tamil Nadu (312 MW), Karnataka (272 MW), Rajasthan (270 MW) and Uttar Pradesh (223 MW) are the top five states accounting for 54% of the total market—according to Bridge To India’s latest India Solar Rooftop Map report

Eliminating emissions from the air would increase solar radiation by an average of 11%, allowing solar cells to generate one tenth more electricity claim researchers in a new study. Focusing on China, they say an additional 85-158 TWh of electricity could be generated annually in 2040, if the air was clean.

Sustainable development expert Auroville Consulting has launched the Solar Village Search Engine to help fund its Solar Village Initiative, which aims to power 100 villages in Tamil Nadu with solar by the year 2030.

A renewable energy system in 2050 is technically possible and economically viable for India, with the levelized cost of electricity falling from the current €58/MWh (Rs4,626) to €52 under one scenario in a recent report, and to €46 in another that included demand for power, water desalination and non-energy industrial gas sectors.

As new cell and module concepts move into large-scale production, and efficiencies are pushed ever higher, manufacturers of flash testing equipment must innovate to ensure their tools can provide reliable measurements, and cope with ever expanding production throughput. The expansion of bifacial technology beyond niche applications in particular raises new issues for flash testing standards. pv magazine spoke with several flasher manufacturers to shed light on the latest developments in this segment.

The iSTAR-C program of India’s International Solar Alliance (ISA) was adjudged an outstanding project during the Paris Peace Forum this month. The program is one of many ISA initiatives to develop solar resources in member countries.
