The choice of the solution varies depending on the approach used. With the Phantom 336-IR it is possible to fly for a first inspection to identify hotspots of the whole extension of the photovoltaic field. Then we proceed to an accurate analysis from the ground. With the Matrice 100 thanks to the double battery with greater flight range it is easier to proceed with only one flight at a preliminary inspection and then follow with careful verification of the areas of greater interest.
