Introduction:
Solar potential estimation for the IIT Mandi campus comprising a total of 96 buildings , spread over 538 acres and grouped into 3 clusters has been carried out using our TSL design Studio software.
Drone site survey was for accurate 2D and 3D modeling. For viewing the 3D models of the building with panel placement click here (link). Further, detailed energy analysis and financial estimates have been carried out.
Presented here below are 2 workflows where our company can add value to organizations:
- Large Scale Analysis
- Accurate roof site survey for remote work
Workflow:
Methodology:
Drone-enabled aerial site survey
Due to IIT Mandi's remote topography, good-quality satellite images were not accessible from open sources like Google Maps, Bing Maps, etc. Due to this, we conducted an aerial site survey using drones to get high-quality images.
Data processing
Using suitable photogrammetry software, the images were processed to obtain an orthomosaic map.
Site reconstruction and 3D modeling
Using the inbuilt feature of 3D modeling in our TSL design studio, three-dimensional models of each of the buildings in all three clusters were created.
- Step 1: Upload ortho mosaic view of the building and scaling for real dimensions
- Step 2: Capture measurements using smart tools within 5 cm accuracy
- Step 3: Modeling of building in Solar Labs design software
Solar capacity analysis
Solar PV Potential for School Annex
Specific generation in units of kWh/kWp/year was estimated. A detailed loss analysis chart is also presented below.
Key Results:
Through this process, we determined the following results:
Results were obtained with
a) High precision of solar potential estimates
b) Time saved due to faster data collection and processing
c) Better standards of safety were ensured and the need for climbing roofs eliminated
Conclusion:
The conclusions and inferences drawn from the case study conducted are given below.
- There is a substantial time saving achieved by using design software which offers a common platform to perform multiple tasks such as 3D modeling, rooftop design, commercial reports, shading reports CAD layout, and SLD.
- The UAV-based rooftop area mapping effectively eliminates the problem of data that is out of date and this reduces delivery time and improves the effectiveness and usefulness of the software.
- The flexibility of creating multiple designs and pitching them to the end customers helps solar installers reduce the business cycle and increase sales.
- ARKA 360 can provide consultancy services to organizations looking for solar potential analysis.
Solar potential analysis at such a large scale with 96 buildings on the campus spread over an area of 538 acres is quite strenuous. But with the help of TSL design studio, complete solar design and potential estimation took just over a week, which earlier would have easily taken months to complete.
In addition, the softwareοΏ½s flexibility to use drones as well as satellite images for design allows design engineers to render precise models with accurate estimations, especially for remote areas where satellite images are quite blurry.
The shading reports generated using the software have been validated by TUV Nord India. It is also being widely accepted by various leading organizations such as Renew, Amplus, UniraSunEdisonson, etc.
So in this era of automation, we are trying to optimize our workflow while at the same time reducing human intervention to a bare minimum. This design software offers a robust design with significant time savings.
- ARKA 360 can help Solar EPCs gain a competitive advantage with accurate data.
- Drone service providers can partner with us to provide data and services to solar EPCs.
- Smart city missions can better use 3D data for solar microgrid designs
- Energy storage planning in cities for smart mobility solutions
