01 Sep 2D ORTHOMOSAIC IMAGERY – PLANNING FOR SOLAR PANEL INSTALLATION USING DRONE DATA SERVICE
With increasing awareness about the benefits of renewable energy (RE) not just to the environment but also the economy, Malaysia’s solar energy industry is set to improve and grow further.
And this become the main contribution factor for emergence of UAVs as the go-to tool not only during inspection but from the very early stage of planning. It is set to accelerate, as the trend towards adopting renewable energy is expected to grow massively in the coming years.
Drones have become a vital tool for solar panel planning and inspection, collecting data more than 80% faster than manual methods and improving safety by avoiding hazardous man-hours.
Orthophoto mapping have various application in commercial and industrial property. One of its very useful function is during planning to locate the strategical position for solar panel on the rooftop.
Solar panels, also known as photovoltaic (PV) panels, will be installed as a component of a system for capturing and storing energy from light utilizing solar cells. Solar panels may be configured as free standing installations or may be installed onto sundry types of structures. Solar panel installations may include multiple different components, such as, for example, frames, inverters, batteries, and the solar panels themselves.
Prior to the installation of solar panel, it is vital to plan and analyse the area to best optimize the solar panels output. For today’s short topic, we will discuss on 2D Orthomosaic Imagery features, how it can help to locate the best position for solar panel installation during planning phase.
Recording Drone Image
This project is categorized as a minor task, therefore DJI Phantom 4 Pro drone were selected. For its best resolution, more facile to handle and during the process of image recording. As a customary, we followed the standard requisite for overlap and lateral overlap of 80% and 75% respectively.
After the flight planning conducted, we deployed the drone to record the images of selected building for solar panel installation. We have to make sure the rooftop is visible from branches or relief displacement.
Relief displacement is the shift in an object’s image position caused by its elevation above a particular datum. For vertical or near vertical photography the shift occurs radially from the nadir point.
Identification of Obstacle Area
We studied the rooftop equipment to identify the obstacle. In the solar industry, equipment or other objects that impact the ability to site solar modules are referred to as “obstructions” on the building’s roof. These rooftop obstructions are anything that takes up space on the rood – skylights, heating and cooling equipment, billboards, vent stacks, elevator penthouses, and the like. For initial assessment it is sufficient to note the level of obstructions very generally, such as minimal, moderate, or extensive. Roofs that gave minimal equipment tend to be better candidates. Moderate rooftops may be fine, while extensively cluttered rooftops can present challenges when it comes to finding enough space for modules, as well as for installing them in an expedient manner. This can drive up costs and make maintenance of the solar array and the roof itself more difficult. If we do not know how to classify the roof, a quick review of the building on an aerial satellite image application like Google Earth will give a good idea of how much rooftop equipment exists on the building.
These are the information about general of the part of a roof.
ANALYSIS AND RESULTS
Potential Area of Solar Panel Installation
Analysis for the designated area of solar panel installation as below:
Based on Figure 1, we identified that the rooftop of the commercial building, obstructions level is moderate. This is a simple method to check and evaluate the position of solar panel based on drone images.
Figure 2, the unsuitable areas is highlighted in red as obstructions. The areas should be steer clear from installing solar panel. They consist of difference height, saddle, eaves edge and air conditional store
Advantages UAV Data Services
Advantages between planning using traditional method and UAVs data service:
Versatility, multi-diverse and delivering limitless solutions. That is how we describe OFO Tech. We explore new things on daily basis, and we develop innovative solutions for our customers using the latest and greatest in technology. 2D Orthomosaic imagery has been utilized in various sectors, with a little imagination and technical knowledge, we can deliver such added value such to identify problem ahead of time for better planning and optimizing the land/area.
Solar panel installations are expected to rise throughout the Asia and surrounding regions in coming years. A jump in installations means an increase in pre-installation planning and inspections. This bodes well for the drone data service industry. Ultimately, our solutions are far more great; effective than traditional method– helping client to increase efficiency, capture incredibly accurate data and enhance safety.
We are excited to announce our next entry, “IoT –Smart Farming.”
We will be discussing about Internet of Things (IoT) and how it will be a key to an extraordinary evolution for our Agro Plantation.
