PDF Original (English)

Rooftop Solar Array — Quarterly Performance Summary

This summary covers the second quarter of operation for the 120-panel array on the roof of Building C. Output figures come from the inverter log; irradiation values come from the on-site pyranometer.

Month Irradiation (kWh/m²) Output (kWh)
April 142.6 5,590
May 168.3 6,580
June 175.9 6,710

Expected output is estimated with the standard yield formula, where A is the panel area, r the module efficiency, H the irradiation and PR the performance ratio:

E=A×r×H×PR

June output was 3% below the estimate. The inspection on 2 July found dust on the eastern row; the panels were cleaned the same day.
