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

panelsbinocular 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

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

efficiency
