The Solar Labs presents here a case study. Objective : Determine solar potential for electricity generation of 100 buildings spread over 500 acres. Innovative approach that provides accuracy and demonstrates a unique use case for Large scale solar in India

1. Powerful software for solar design and sales growth

2. Visualizing Rooftop Solar
Topic of discussion is Electricity from Solar Photovoltaics, Not solar thermal

3. • TSL was founded by IIT alumni to accelerate solar adoption in the world.
• The company brings the latest AI technologies to the solar industry, thereby
improving the quality of processes and reducing cost in the form of the finest
software in the industry.
• The software has been used to estimate 500 MW+ of solar capacity across India.

4. Who uses The Solar Labs software?

5. KEY BENEFITS
• Our SAAS solar design tool help solar installers and developers design optimized solar systems
• This increases energy output (clean electricity) and reduces the cost of installations
• We also enables installer to create a data driven quotation and report for clients within 20 minutes,
drastically reducing their turnaround time.
About TSL Design Studio
It is currently being used
to design over 400
systems per week by our
customers.

6. Mission – Integrate 3D data from drones for city scale analysis
with 2D/3D Analysis for Generation, Financials, Shadow Analysis
The Future

7. The need
• Tender document formulation for
a college campus to source
power from solar
The key challenge
• Complicated design of buildings
• Hilly terrain
Case Study : Solar Potential Estimation at IIT Mandi
Collaborators
• Data collection – Beyond Gravity
• Data processing - Dronamaps

13. Sun Path Simulation

14. Why do we need Sun Path Simulation

15. Factors that affect solar potential and design
1. Shading
• Caused due to trees, roof obstructions and terrain
2. Module Rating
• In this analysis we have used 330Wp modules
3. Module tilt and azimuth
• Optimum tilt angle is 25⁰-30⁰ w.r.t ground and
azimuth is 180⁰ i.e. True South
4. Aesthetics factors that limit options
• IIT Mandi has a unique roof design, with pitched
and sloping features
