Solar farms can cover anything between 1 acre and 100 acres, and are usually developed in rural areas. We can inspect Solar PV panels for anything such as surface debris and damage, bird droppings and obstructions to the panel.
In the past surveys were generally done either on foot or through aerial vehicle. Both can be time-consuming, or even dangerous in certain conditions. But today’s modern surveyors can be done by use of aerial drones which can vastly minimise danger to people.
UAVs are able to survey a site from the air, with drones that fly close to the ground. With a UAV, a surveyor is able to produce extremely detailed surveys quickly, without any risk to a crew. This is the ideal type of survey for solar farm construction.
Note: We work alongside Surveyors and engineers, but we ourselves are not qualified surveyors.
We use a Mavic Pro 2 with a mounted Hasselblad camera. This has a superior Sony sensor; better than than that of DJI’s standard drone gimbal cameras, and this one in particular has a 1-inch sensor with 14 stops of dynamic range with RAW capability. We carry our CAA certification for PfCO (Permission for commercial operations) with us, along with safety equipment which is a legal requirement, such as a small fire extinguisher, a drone-landing pad, safety cones, fire blanked and a high vis jacket as standard.
Aerial surveys require careful strategic planning, studying the specific objective, the intention, the method in which we
plan and prepare the drone flight, administration of safety checks and flight plans and the communication with a flight observer on the ground.
- An observation is first undertaken of the area, to check for any hazards in the air and on the ground in a radius around the perimeter. If the area is within radius of a protected airspace such as an airport, we’ll contact the nearby ATC and attempt to gain clearance (this part can take up to 10 days).
• A flight plan is prepared, taking into the area to be surveyed, with a NOTAM to be established for the given time and day of flight. We’ll also check wind speed and direction, take-off and landing areas (entry and exit points) and even check ordnance survey maps and Google maps to ensure there are no hidden problems.
• This requires experience and skill to ensure the data is captured to the correct specification and safely.
• We’ll turn up on site on the planned day and plan a short on-site observation. This will be to check the pre-flight assessment was accurate and to tune situational awareness onto the project.
• I’ll provide a short briefing of the flight objectives and brief you on any hazards and procedures that may occur.
• We’ll get the necessary images and/or footage of the objective and land safely.
• The images will be downloaded from the UAV and processed. These can be sent to you or your surveyor within the same day.
