6.3. Installation

The LP02 is usually installed horizontally, but can also be installed at any

angle including an inverted position. In all cases it will measure the flux that is

incident on the surface that is parallel to the sensor surface.

Site the LP02 to allow easy access for maintenance while ideally avoiding any

obstructions above the plane of the sensing element. It is important to mount

the LP02 such that a shadow will not be cast on it at any time.

If this is not possible, try to choose a site where any obstruction over the

azimuth range between earliest sunrise and latest sunset has an elevation not

exceeding 5°. Diffuse solar radiation is less influenced by obstructions near

the horizon. For instance, an obstruction with an elevation of 5° over the

whole azimuth range of 360° decreases the downward diffuse solar radiation

by only 0.8%.
