Comparison assumes optimal southern roof exposure, no shade, and standard 400W monocrystalline panels.
| System Size | Panel Count | Gross Cost | Federal Credit (30%) | Net Cost | Payback Time | 25-Yr Net Profit |
|---|---|---|---|---|---|---|
| 5 kW | ~13 panels | ₹305,000 | -₹91,500 | ₹213,500 | 3.7 years | ₹1,768,002 |
| 8 kW | ~20 panels | ₹488,000 | -₹146,400 | ₹341,600 | 4.1 years | ₹2,802,114 |
| 10 kW | ~25 panels | ₹610,000 | -₹183,000 | ₹427,000 | 4.3 years | ₹3,490,242 |
| 12 kW | ~30 panels | ₹732,000 | -₹219,600 | ₹512,400 | 4.4 years | ₹4,147,801 |
Federal Tax Incentives reduce solar system acquisition costs by 30% instantly. In Mangaluru, purchasing a larger system like the 10 kW system typically increases the 25-year net return because it offsets higher-tier, expensive utility company electricity rates.
Net Sizing Estimate
For a standard home in Mangaluru with an average bill of ₹2500, a 2.5 kW array covers peak power needs. The net cost of ₹92,500 factors in the immediate PM Surya Ghar Yojana subsidy.
Net Metering & Grid Export
Karnataka enforces a Grade B+ net metering structure. Power exported to the grid during sunny daylight hours will be credited against grid energy imported at night, shielding you from expensive utility fees.

Rooftop Solar Financial Feasibility Analysis in Mangaluru
Installing a solar panel array on your home in Mangaluru is a highly structured financial investment. Because electricity rates under your local DISCOM in Karnataka are high, averaging ₹8.20/kWh, each kilowatt-hour your panels produce offsets top-tier, expensive utility company billing slabs. This accelerates your payback timeline significantly.
Solar generation yields depend heavily on solar irradiance. Mangaluru receives an average of 5.1 peak sun hours per day. While lower than desert climates, this sunlight profile is more than sufficient to fully offset standard household electrical consumption, especially when matched with Karnataka's grid banking systems.
In addition, net metering regulations play a vital role. With Karnataka's Grade B+ net metering framework, any excess solar energy you generate during peak afternoon hours can be exported back to the grid. Under these rules, exported credits help offset grid consumption at night, keeping your utility bills close to zero.
