To clarify and to respond, albeit remotely, to statements in other posts, this installation is of very poor quality
The SRS are excessively close together, the height from the ground and the exposure are correct, but their extreme proximity triggers high uncertainties that vary based on the direction of natural ventilation
The SRS that finds itself working upwind of the others will always have an advantage, and gradually those "behind" it will find themselves in a worse situation
This is an installation that can provide acceptable comparison data only in the long term in order to cover the majority of different possible situations, the daily data, or worse, the instantaneous ones are seriously affected by this.
Let's all take this into account in our evaluations, even though there are certainly installations that are decidedly better than mine
