Solar Horizon Estimator

Wagner & Co Solar Horizon Shading Meter Solar PV Test Equipment

Solar Horizon Meter. A sun path indicator used to determin relevant annual irradiation curves.

This device allows examining whether trees, buildings etc, will cast shadows on planned module or collector surfaces. Shadowing can result in reduced effectiveness of a solar energy system.

The transparent sun path sheet displays the relevant annual irradiation curves with respect to the daily sunshine hours.

If you look through the device after aligning it South using the compass, you will be able to identify objects which will obstruct the path of the sun at a given time and therefore cast a shadow.

The installation location for solar collectors or solar modules is optimally chosen when no shadowing occurs or shadowing only occurs very early or late during the day.

Especially during the transition periods in Autumn and Spring a solar system with combined hot water and space heating support should not be subject to shadowing. A system mounted on a roof with Western orientation naturally must not be shadowed during the afternoon.
