Solar generation depends on the solar irradiation that falls on photovoltaic panels. India has witnessed up to 7% below-average solar radiation variability between 2018 and 2022 and between 3% and 10% in 2024. Slovakia-headquartered Solargis is an online platform with solar design, energy simulation, data analytics, and solar and meteorological data to support various stages of solar power projects. In this interview, Solargis’ CEO Marcel Suri speaks about the impact of a drop in irradiance on solar project performance, his company’s solutions for the solar industry, and forecasting technology trends.

The draft Punjab Green Hydrogen Policy, released by the Punjab Energy Development Agency, targets achieving a 100 kilo tons per annum production capacity of green hydrogen and ammonia by 2030. Per the draft, the existing incentives under the “Punjab Industrial and Business Development Policy 2022” will be extended to new green hydrogen and ammonia ventures and the expansion of existing units.

UltraTech Cement, an Aditya Birla Group company, will source renewable energy from AMPIN Energy Transition’s special purpose vehicle (SPV) AMPIN C&I Power Eight. The company entered energy supply, share subscription, and shareholders agreements to acquire a 26% equity share in AMPIN C&I Power Eight, investing ₹255 million (~$2.98 million). The SPV was incorporated in January to set up a 75 MW DC/50 MW AC solar power project on a captive basis at the Sindhari village in Rajasthan’s Balotara district.

Coal India invited bids to set up a 1,000 MW (AC) ground-mounted solar project on a turnkey basis at the Rajasthan Rajya Vidyut Utpadan Nigam’s 2,000 MW solar park in Rajasthan’s Bikaner district. Bids must be submitted by May 7, 2025. Bids will be opened on May 8. The scope of work entails the design, engineering, procurement, construction, and commissioning of the project. It also involves conducting the associated civil works and providing comprehensive operation and maintenance services for two years.

Rajasthan Electronics and Instruments invited bids for rate contracts to develop 1.14 MW grid-connected rooftop solar projects on government buildings in Andhra Pradesh, Karnataka, Kerala, Tamil Nadu, Telangana, Puducherry, and Lakshadweep. The rate contracts will be valid for one year and can be extended per requirement. Bids must be submitted by May 6, 2025. Bids will be opened on May 7. The scope of work entails the design, engineering, survey, manufacturing, unloading, storage, erection, testing, and commissioning of the solar projects. It also involves integrating the projects up to the ground floor level with the grid.

The Fraunhofer Institute for Solar Energy Systems ISE announced that its latest research has found that ultraviolet tests rate degradation of tunnel oxide passivated contact silicon solar modules significantly higher than performance reduction in real-life conditions. The research shows that common UV tests can significantly exaggerate the degradation effect.
