Technical Inspections by
UAVs

Solar Farms Inspections by
UAVs

solar farms inspections by UAVs
preventive inspections
to check if some elements - arrays, modules,
cells -
do not work well and thus are overheated

What is needed Why is needed
UAV surveying
thermal eye observing differences in temperature and detecting
overheated elements (clearer in the thermography)
coupled eye
in the visible band
complementing thermal observations for clarifying
eg shadows – and evidencing some crack or rubbish
panels
binocular vision
observing the same scene by different bands at the
time: both thermal and visible sensor on board
live viewing following the survey better
recording on board analyzing the acquired data later
traditional way of thermal surveying by UAV
on solar farms

big solar farms
are monotonous landscapes
to evidence overheated elements,
i.e. hot spots, also in cells
each thermal video frame will not contain
anything more than …

…modules…
…modules…
… and still modules!
for huge solar farms
the post-processing time to locate
the detected anomalies over the map
is so much that the benefit
of the fast aerial surveys are lost!
location aware
system can
help

new way of inspecting
• helps in surveying
• helps in post-processing
• automatically produces the right survey

geospatial inspections of PV plants with light
RPAS

KEY FEATURES
• Plug & Play
• Specific for UAV use
• Independent by any UAV
• Geospatial software with domain
experience inside
- locating anomalies on the
map
- automatic generation of the
survey Report
• Getting started in surveys quickly:
- easy to use
- fast initial training also in
remote

ADVANTAGES
Fully exploiting geospatial
content of data
• Speed up the delivery of
the results
• Useful for large PV field
and roofs
• Real alternative to
conventional survey
methods
• More efficient than
"traditional" drone
inspections
• Strategic for O&M
contracts linked to
