How we calculated this

Daily generation = panel Wp × peak sun-hours × system efficiency (0.78). Sun-hour values are 20-year averages from NASA POWER, sourced for Geneva's coordinates (46.20, 6.14). Real conditions vary by panel tilt, orientation, shading and weather — use the live calculator for site-specific results.
