The demand for high-quality solar thermal equipment has grown significantly in India, driven by increasing adoption of sustainable energy solutions. With this rise, ensuring product safety, reliability, and compliance has become essential for manufacturers. This is where the BIS Certification for Solar Thermal Systems plays a vital role. BIS certification helps manufacturers demonstrate that their solar thermal products—such as collectors, heating units, and solar water systems—are tested and comply with the required standards. If you are planning to enter the Indian market with such products, understanding the complete process is crucial.
This article provides a clear step-by-step guide to BIS for Solar Thermal Systems to help manufacturers, suppliers, and startups navigate the compliance process smoothly.
Step 1: Identify the Applicable BIS Standard
The first stage is understanding which Indian Standard (IS) applies to your specific product. Solar thermal systems and components fall under defined BIS standards that outline testing requirements, performance criteria, and safety parameters. Manufacturers must review these standards carefully to determine scope and compliance obligations before proceeding.
Step 2: Prepare Required Documents
Documentation plays a major role in securing BIS certification. Applicants must collect detailed technical files, product specifications, test reports, manufacturing process details, and quality management-related documents. In addition, an authorized Indian representative is required for foreign manufacturers applying for BIS under the FMCS scheme.
Step 3: Product Testing at BIS-Recognized Laboratory
Once documents are ready, the product undergoes testing at a BIS-recognized laboratory. This step is essential because the BIS lab evaluates the product’s performance, durability, energy efficiency, and safety in accordance with the relevant Indian Standard. The testing process is highly technical, and the test report must be submitted along with the application.
Step 4: Submit Application to BIS Portal
After testing is complete, applicants must file an online application on the BIS portal. This includes uploading documents, test reports, and all required details. During this stage, fees related to application processing, testing, and marking must be paid. A well-prepared application reduces the chances of rejection or delay.
Step 5: Factory Audit and Inspection
For certain categories, BIS officials conduct an inspection to verify the manufacturing process, equipment, quality control mechanisms, and product consistency. The factory audit ensures that products manufactured in future batches maintain the same quality as those tested in the laboratory.
Step 6: Grant of BIS Certification
After document verification, product testing, and inspection, the Bureau of Indian Standards grants certification. This authorizes the manufacturer to use the BIS Standard Mark on solar thermal products. The mark not only enhances credibility but also helps in market acceptance, tenders, and regulatory approvals.
Step 7: Compliance and Renewal
Once you receive BIS certification, maintaining compliance is essential. Manufacturers must follow marking requirements, ensure consistent product quality, and undergo surveillance audits when required. BIS certificates are typically valid for a fixed period and must be renewed before expiry.
Why BIS as a Service Matters for Solar Thermal Manufacturers
BIS approval is more than just a compliance requirement—it helps build trust with consumers and strengthens product reliability. When manufacturers understand BIS as a Service, they get access to a complete support process that includes consultation, documentation, testing guidance, and end-to-end assistance. This makes certification faster and ensures better accuracy at every stage.
