Rajasthan Electronics & Instruments Limited (REIL) has announced a tender for a 17.55 MW rooftop solar project on government buildings across India. The contract covers the survey, design, supply, installation, testing, and commissioning of the project, as well as one year of maintenance with an option for extension.
Bidding and Eligibility Requirements
Bidders must submit an Earnest Money Deposit (EMD) of 2% of the estimated cost for each selected region; this amount will be adjusted for those bidding on multiple regions. Selection is based on techno-commercial eligibility, and only bidders who meet the specified criteria will be considered.
Eligible participants must be companies or firms registered in India with prior experience designing, supplying, and installing grid-connected solar plant systems. The rooftop solar installations will range from 51 kWp to 1000 kWp per building.
Work will be distributed between L-1 and L-2 bidders, with L-1 receiving 70% of the total capacity and L-2 the remaining 30%. All allocations will follow the L-1 rate for the respective region, though REIL retains the right to adjust these based on customer requirements.
Technical and Construction Standards
The solar plant systems must feature Mono-Perc solar panels with a minimum capacity of 540Wp, complying with Ministry of New and Renewable Energy (MNRE) guidelines issued on 29 April 2024. To align with the government’s “Make in India” initiative, solar inverters must be sourced from Class-I local suppliers. The Operations and Maintenance (O&M) period for the systems will be ten years from completion, though this may be adjusted based on customer needs.
All solar PV modules must be sourced from Class-I local suppliers and adhere to quality standards including IEC 61215, IS 14286, and IEC 61730. Modules must include a minimum warranty guaranteeing 90% of their rated output for the first ten years and 80% for the next fifteen. For traceability, each module must also be equipped with an RFID tag.
Mounting structures for the solar modules must meet industry standards. These structures can be made from hot-dip galvanised iron, aluminium, or mild steel, with mild steel preferred for elevated installations. The final design must account for wind load and other environmental factors, and the structural plans must be approved by a certified laboratory or chartered engineer.
All installations must include meters to monitor energy generation and net consumption, and these must comply with local DISCOM regulations. Solar meters must carry a minimum warranty of ten years. If a meter fails during this period, the bidder is responsible for its replacement.
Opportunities and Future Prospects
The REIL solar project tender presents a significant opportunity for Indian companies in the renewable energy sector, promoting the adoption of rooftop solar PV systems in government buildings across the country. This initiative aligns with national renewable energy goals by prioritising sustainability, local sourcing, and long-term efficiency. Companies that meet the eligibility and technical requirements can participate in this large-scale solar initiative and contribute to India’s clean energy transition.
