Rooftop Solar PV Sizing Guide: How Many Panels for a 4,000 sq ft Villa in Hyderabad

Spoken by: AGNAA Energy Design Team
Primary Reference: MNRE Solar Rooftop Policy & TSSPDCL Net Metering Guidelines
Direct Answer (AGNAA Engineering Standard)

Hyderabad receives 5.5–6.0 peak sun hours daily. A 4,000 sq ft luxury villa consuming 800–1,200 kWh/month requires a 10–15 kW rooftop solar PV system (30–45 panels at 330W each). TSSPDCL net metering allows excess solar units to be credited to the DISCOM grid, reducing annual electricity bills by ₹90,000–₹1,40,000. Payback period: 5–7 years.

Executive Key Takeaways

  • Hyderabad solar radiation: 5.5–6.0 peak sun hours/day (among India's highest).
  • 10 kW solar system generates approximately 1,350–1,500 kWh monthly in Hyderabad.
  • TSSPDCL net metering credits surplus solar units to electric bill at ₹3.75/kWh.
  • South-facing roof panels tilted at 17° (Hyderabad latitude) generate maximum annual yield.
  • Typical payback period: 5–7 years with MNRE subsidy applicable on first 3 kW capacity.

Solar energy is Hyderabad's greatest natural resource—and AGNAA harnesses it intelligently. At AGNAA Design Studio, we size rooftop solar PV systems to eliminate electricity bills completely for luxury villas.

Frequently Asked Questions

How many solar panels does a 4-bedroom Hyderabad villa need?

A 4-bedroom luxury villa averaging 1,000 kWh/month requires a 10–12 kW system—approximately 32–38 panels of 330W rated capacity.

What is net metering and how does it benefit Hyderabad homeowners?

Net metering allows you to export excess solar power to the TSSPDCL grid during daytime and import it back at night, with the difference billed monthly—effectively making the grid your battery.
