Solar ROI for Commercial Buildings in Pakistan 2026
A practical analysis of solar return on investment for commercial buildings in Pakistan — system sizing, savings, and payback periods.
Solar energy has become one of the most compelling investments for commercial building owners in Pakistan. With electricity tariffs at historic highs and solar panel costs continuing to fall, payback periods have shortened dramatically.
Current Solar Economics
A commercial on-grid solar system in Pakistan currently costs Rs 120,000–160,000 per kW installed, including panels, inverter, mounting, and installation. A 50kW system for a medium commercial building costs approximately Rs 60–80 lakh.
Savings Calculation
A 50kW system in Karachi generates approximately 200–220 kWh per day (based on 4.5–5 peak sun hours). At current commercial tariffs of Rs 35–45 per kWh, this represents daily savings of Rs 7,000–10,000, or Rs 2.5–3.5 lakh per month.
Payback Period
At current tariffs and system costs, commercial solar systems in Pakistan are achieving payback periods of 3–5 years. With net metering, excess generation can be exported to the grid, further improving returns.
Key Considerations
Roof structural capacity must be verified before installation. Shading analysis is essential — even partial shading significantly reduces output. Inverter quality is critical for long-term reliability. Build Axis provides independent solar feasibility assessments and installation supervision.
