As solar power adoption accelerates in India, the choice of cabling solutions has become a crucial factor in ensuring safe, efficient, and long-lasting photovoltaic (PV) systems. One of the key benchmarks introduced by the Bureau of Indian Standards (BIS) is the IS: 17293:2020 solar cable standard, designed specifically for solar DC cables with a rated voltage of up to 1500 V d.c.
In this blog, we’ll explore how using BIS certified solar cables in India enhances both the lifespan and performance of solar PV projects, and why project developers and EPC contractors should prioritize ISI-marked solutions.
Why Solar Cables Need Special Standards
Unlike ordinary electrical wires, solar PV cables are exposed to:
- Direct sunlight and UV radiation
- Wide temperature fluctuations
- Mechanical stress during installation and maintenance
- Outdoor moisture, dust, and chemical exposure
This is where the Solar DC cables IS standard plays a vital role. Cables compliant with IS: 17293:2020 are engineered to withstand these extreme conditions, ensuring both safety and long service life.
Key Benefits of IS: 17293:2020 Solar Cable Standard
1. Long Lifespan of Solar PV Cables
ISI marked solar cables lifespan is significantly higher than conventional wires. Thanks to advanced insulation and sheathing materials, these cables can last 25+ years, matching the lifetime of solar panels themselves.
2. Flame Retardant Safety
Flame retardant solar cables India solutions minimize the risk of fire hazards in solar farms, residential rooftops, and commercial installations. Their low smoke and halogen-free properties ensure safer operation in case of electrical faults.
3. Superior UV and Weather Resistance
UV resistant solar DC cables maintain flexibility and strength even under constant exposure to sunlight, ozone, and varying weather conditions, reducing chances of cracks or insulation breakdown.
4. High Performance for Modern Solar Projects
With solar power plants moving toward 1500 V d.c. systems, the high performance solar cables standard ensures minimal energy losses, reliable conductivity, and compatibility with large-scale solar installations.
5. Regulatory Compliance and Trust
Choosing BIS certified solar cables India not only assures compliance with national safety codes but also boosts the credibility of solar developers in tenders and inspections.
Why Choosing the Right Solar Cables Matters
The cabling system may represent only 5–10% of a solar project cost, but its impact on performance and safety is massive. Poor-quality wires can lead to:
- Power losses
- Short circuits and fires
- Premature system failures
On the other hand, selecting the best cables for solar PV projects built to IS 17293:2020 cable benefits ensures:
- Higher energy yield over the project lifetime
- Reduced maintenance costs
- Long-term reliability
Conclusion
For India’s solar mission to succeed, every component—from modules to cables—must meet the highest quality standards. The IS: 17293:2020 solar cable standard offers a trusted benchmark for durability, safety, and efficiency. By opting for long life solar PV cables that are BIS certified, developers and EPC contractors can secure the maximum lifespan and performance of solar PV projects.
If you’re planning a new installation, make sure your project includes ISI marked, flame retardant, UV resistant solar DC cables—because the right cables don’t just connect your system, they protect your investment for decades.
