Specific Yield (kWh/kWp)

Specific yield is annual generation divided by system size — units produced per kWp per year. Indian rooftops typically deliver 1,400–1,700 kWh/kWp/year depending on region and design quality.

It is the cleanest number for comparing systems of different sizes or validating a vendor’s generation promise. Below ~1,300 in most of India signals shading, soiling, or design problems worth investigating.
