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 survey, design, supply, installation, testing, commissioning and maintenance for one year, with an option for extension.
Bidding and Eligibility Requirements
Bidders must submit an Earnest Money Deposit (EMD) for each selected region, amounting to 2% of the estimated cost. If bidding for multiple regions, the EMD will be adjusted accordingly. Bidders will be selected based on techno-commercial eligibility, and only those meeting the specified criteria will be considered.
Eligible participants include companies or firms registered in India. Bidders must have prior experience in designing, supplying and installing grid-connected solar plant systems. The rooftop solar project installations will range from 51 kWp to 1000 kWp per building. The work will be distributed based on L-1 and L-2 categories. L-1 bidders will be allocated 70% of the total capacity, while L-2 bidders will receive 30%. All allocations will follow the L-1 rate for the respective region. REIL retains the right to adjust allocations according to customer requirements.
Technical and Construction Standards
The solar plant systems will feature Mono-Perc solar panels with a minimum capacity of 540Wp, complying with the Ministry of New and Renewable Energy (MNRE) guidelines issued on 29 April 2024. Solar inverters must be sourced from Class-I local suppliers, aligning with the government’s “Make in India” initiative. The O&M period for the solar plant systems will be ten years from completion, with adjustments possible based on customer needs.
All solar PV modules must be sourced from Class-I local suppliers and adhere to quality standards such as IEC 61215, IS 14286 and IEC 61730. Modules must have a minimum warranty guaranteeing 90% of the rated output for ten years and 80% for the next fifteen years. Each module must be equipped with an RFID tag for traceability.
Mounting structures for the solar plant modules must meet industry standards. These structures may be made from hot-dip galvanised iron, aluminium, or mild steel, with mild steel preferred for elevated installations. The final design must consider wind load and other environmental factors. A certified laboratory or chartered engineer must approve the structural design.
All installations must include meters to monitor energy generation and net consumption. Solar meters must have a minimum warranty of ten years. These meters must comply with local DISCOM regulations. If a meter fails within the warranty period, the bidder will be 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. This project will enhance the adoption of rooftop solar PV systems in government buildings across India. The initiative aligns with the country’s renewable energy goals by prioritising sustainability, local sourcing and long-term efficiency. Companies meeting the eligibility criteria and technical requirements will have the chance to participate in this large-scale solar initiative and contribute to India’s clean energy transition.
