Choosing a solar panel is not just about price; efficiency, durability, and warranty matter, especially under Pakistan’s harsh climate.
Key Performance Indicators
- Efficiency – Percentage of sunlight converted to electricity (typically 17‑22%).
- Temperature Coefficient – Power loss per degree Celsius above 25°C. Lower values (< ‑0.4%/°C) are better for hot climates.
- Nominal Operating Cell Temperature (NOCT) – Indicates how hot panels get under standard conditions.
- Warranty – Product (10‑12 years) + Performance (25‑30 years) guarantees.
