INSTALLATION & MAINTENANCE
Installation:
The site for an upward-facing pyranometer should be free from any significant obstructions above the plane of
the sensing element and should be readily accessible. If practicable, instrument should be located so that (1.) a
shadow will not be cast on it at any time (e.g. by radio masts, etc.); (2.) it is not close to light-colored walls or
other objects likely to reflect sunlight onto it; and (3.) it is not exposed to artificial radiation sources. A flat roof
provides the best location, or a rigid stand with a horizontal upper surface some distance from building
structures or other obstructions. The stand should be sufficiently rigid that the horizontal position of the
receiving surface does not change, especially during high winds. Precautions should be taken to avoid
subjecting the instrument to severe shocks or vibration.
Calibration / Cleaning Frequency:
Recalibration is suggested every two years, preferably by letting a higher standard run parallel during two sunny
days and comparing daily totals.
The sensor should be kept clean, using water or alcohol.
