Solar Energy in Ludhiana: Complete 2026 Guide
Ludhiana is India's cycle and hosiery capital. Its spinning mills and cycle factories are among Punjab's largest commercial solar adopters — Ludhiana accounts for 35% of all commercial rooftop solar installed in Punjab. With electricity tariffs charged by PSPCL at ₹5.20/unit and rising every year, switching to rooftop solar is now the single best financial decision a Ludhiana household can make in 2026.
Solar Potential: How Much Can You Generate in Ludhiana?
Ludhiana receives approximately 4.8 peak sun hours per day (based on MNRE solar radiation data for this region). This means every 1 kW of rooftop solar installed here generates about 1,460 units of electricity per year.
For a typical 3 kW system — the most popular size for a 2–3 BHK home — you can expect:
- ~12.0 units per day on average (higher in summer, lower in monsoon)
- 4,380 units per year
- ₹1,872/month savings on your PSPCL electricity bill
- Payback period: ~4.5 years after PM Surya Ghar subsidy
