solar panel
Yes, TopCon solar panels can be installed on sheds/shades, and they are a good choice for such applications due to their high efficiency, bifacial capability, and N-type cell structure (which performs better under partial shading compared to PERC).
But to make them work efficiently on sheds, you need to follow specific design and installation parameters.
✅ Parameters & Guidelines for Installing TopCon Panels on Sheds
1. ✅ Structural Suitability of Shed Material: Ensure the shed is made of steel, iron, RCC, or aluminum frame strong enough to bear additional load.
Load Capacity: TopCon modules usually weigh 23–28 kg. The structure should support:
Panel weight
Wind load (up to 180 km/h in regions like Gujarat/Rajasthan)
Mounting structures
Get structural stability certification from an engineer if large-scale.
2. ✅ Panel Tilt Angle
Recommended tilt for maximum generation:
North India: 20° to 28°
South India: 10° to 15°
If shed is flat: Use adjustable mounting structures.
If shed is slanted: Align tilt angle with south-facing roof slope.
3. ✅ Shadow Analysis
TopCon panels can handle minor shading better than PERC, but full-row or string shading should be avoided.
Use tools like:
Solaredge Designer
Helioscope
PVsyst
Perform morning to evening shading analysis and avoid:
Chimneys, water tanks, high parapets, nearby trees
4. ✅ Bifacial Optimization (Optional)
Many TopCon modules are bifacial — they generate from the back side too.
For sheds:
Use elevated mounting (\~300mm from surface)
Use reflective paint (white or silver) on shed
Allow open ventilation below for rear irradiation
5. ✅ Spacing & Layout Design
Maintain minimum 300–500 mm gap between panel rows to reduce self-shading.
Orientation: South-facing for best performance.
Mounting Structure: Use hot-dip galvanized iron (HDGI) or Aluminum Rail systems for corrosion resistance.
6. ✅ Electrical Considerations
String Design:
Use MPPT optimization to handle minor shading
Choose microinverters or optimizers if partial shading is unavoidable
Inverter Matching:
Inverter should support high efficiency TopCon modules with higher Voc (open circuit voltage)
Check compatibility with bifacial gain
7. ✅ Grounding & Earthing
Proper grounding of both structure and panels is essential for safety.
Use lightning arrestor if shed is tall or in lightning-prone area.
8. ✅ Maintenance Access
Ensure walkways or gaps for maintenance every 3–4 panel rows.
Roof/shed should support foot traffic if cleaning and servicing are to be done manually.
✅ Summary Table
