Rooftop Solar

The New Delhi-based solar products manufacturer will install and commission off-grid solar PV power plants in government office buildings in the Indian State of Uttar Pradesh.

The Haryana-based solar technology startup has announced it has deployed rooftop solar solutions for over 50,000 residential customers across India within four years of its operation.

A recent study by Clean Energy Associates showed that 90% of inspected rooftops had significant safety and fire risks. Here’s how to protect your solar asset.

Mumbai-based Roofsol Energy has installed a 625 kWp rooftop solar plant at Yachio India Manufacturing Pvt Ltd, the India arm of Japan-headquartered plastic fuel tank producer Yachio.

At the Renewable Leadership Summit 2021 held recently in New Delhi, Dinesh Jagdale, joint secretary, Ministry of New and Renewable Energy, also asserted the ministry is working on addressing stakeholders’ concerns to ensure the investments keep flowing into RE capacity expansion and equipment manufacturing. The Summit, organized by Solar Association, also saw Solis launch its new-generation PV plant monitoring platform and off-grid hybrid inverters. 

Solar, like wind, has evolved into a more viable bilateral arrangement business model as prices have decreased and favorable legislation has emerged. Due to significant technical advancements, the solar industry has overtaken wind and has emerged as the favored option.

The Nambiar Bellezea luxury villa community in Bengaluru has got a 160 kW rooftop solar plant installed for its clubhouse, alongside 3-6kW installations on more than 20 villas. The 160kW club installation is powered by 320 numbers of Trina 500 Wp solar modules coupled with 320 Enphase IQ7A micro-inverters.

To achieve the government’s ambitious renewable energy targets, and integrate the two growing sectors of infrastructure and construction and renewable energy, the existing policies and codes for green buildings need to be further enhanced. Most of these rules need to include specific details about energy generation. Right now, these are more to do with energy efficiency. 

Scientists in India developed a mathematical model to predict the output of solar cells and modules in the field. The model was developed and tested using both sun simulator and actual installed modules. The scientists state that their model can be applied to a PV installation anywhere in the world, and that by taking into account module degradation over time their forecasts can be as much as 26% more accurate than existing energy yield models.

The grid-connected solar projects may be set up either as net-metered systems or systems for consumption within premises with no export of power. Bidding ends on November 29.
