As the solar industry grows, so does the risk of duplicate or low-quality solar panels entering the market. For homeowners, businesses, and EPC companies, identifying genuine panels is essential to ensure long-term performance, safety, and return on investment. Here’s a simple guide to help you verify whether a solar panel is original or counterfeit.
Check the Manufacturer’s Label:
Every original solar panel comes with a clearly printed label on the back. It should include:
• Brand name
• Model number
• Serial number
• Electrical specifications (Voc, Isc, Wattage, etc.)
• Country of manufacturing
Duplicate panels often have unclear printing, missing details, or mismatched information.
Verify the Serial Number Online:
Most reputed solar brands offer online serial number verification. Go to the manufacturer’s website and enter the panel’s serial number. If the number doesn’t match or shows an error, the panel may be fake.
Look for BIS or IEC Certifications:
In India and other global markets, original panels must have certifications such as:
• BIS (Bureau of Indian Standards)
• IEC (International Electrotechnical Commission)
These marks ensure the panel meets safety and quality standards. Fake panels often lack certification logos or use incorrect ones.
Inspect Build Quality:
Original solar panels have:
• High-quality framing
• Uniform cell alignment
• Neat junction box installation
• Strong glass coating
Duplicate panels show signs of poor craftsmanship—scratches, rough edges, uneven cells, or loose wiring.
Compare Performance Data:
Use a multimeter or monitoring system to check the output. Genuine panels deliver power close to their rated wattage. Duplicate panels often show significantly lower performance under the same sunlight conditions.
Buy Only from Authorized Dealers:
Always purchase panels from authorized distributors, EPC companies, or registered dealers. Avoid unknown sources or unusually cheap deals—these are common red flags.
Conclusion:
Checking whether a solar panel is original or a duplicate is crucial for long-term reliability and safety. By verifying serial numbers, checking certifications, inspecting build quality, and purchasing from trusted sellers, you can ensure you’re investing in genuine, high-quality solar panels. A little attention today can save you from costly problems in the future.
