Specific Yield
Annual energy produced per kilowatt-peak installed, in kWh/kWp — the figure used to compare sites, and the basis of every revenue projection.
Indian ranges
1,350-1,650 kWh/kWp per year for fixed tilt, 1,650-1,950 for single-axis trackers. Rajasthan, Gujarat and Ladakh sit at the high end; coastal and eastern states lower, partly from irradiation and partly from humidity and soiling.
What quietly erodes it
Temperature (output falls ~0.35%/°C above 25 °C), soiling, shading, cable loss, inverter clipping and degradation. Each is small; together they are the difference between a model and a disappointment.
