• Standard: 19-21% (Earthwave partners, Tata, Adani)

• Budget: 17-19% (Polycrystalline)

A 5kW system with 21% panels needs 240 sq ft vs 280 sq ft for 18% panels.

Important Note: Inverter efficiency matters equally. Before finalizing your system, read everything you need to know before going solar to understand all critical components beyond just panels.

Warranty Structure: Performance vs Product

Performance Warranty guarantees power output over time:
