Question 1

What is the difference between On-Grid and Hybrid solar systems in Pakistan?

Accepted Answer

On-Grid systems connect directly to your DISCO grid via a bi-directional Green Meter, providing maximum ROI by exporting surplus units back to the grid. Hybrid systems add LiFePO4 lithium batteries to provide seamless power backup during grid load shedding.

Question 2

Which solar panels and inverters does electric.com.pk install?

Accepted Answer

We strictly install Tier-1 Bloomberg-listed N-Type TOPCon panels (Longi Hi-MO X6, Jinko Tiger Neo, Canadian Solar) paired with high-efficiency European standard inverters (Huawei, Sungrow, Solis, Knox, Deye).

Question 3

How much rooftop area is required per kW of solar?

Accepted Answer

Flat concrete rooftops require approximately 90 sq. ft. per kW (for elevated galvanized structures to avoid shadow casting). Slanted metallic roofs require ~75 sq. ft./kW, and tile roofs require ~85 sq. ft./kW.

Question 4

How is the return on investment (ROI) and payback period calculated?

Accepted Answer

Based on current 2024–2026 Pakistani electricity tariffs (PKR 56–62/unit), a standard 10kW On-Grid system saves approximately PKR 75,000–88,000 monthly, achieving a full payback within 2.2 to 2.8 years.
