Step 1: Rooftop Area
Plot size: 50 guz, 100 guz, 150 guz, 220 guz, or 500 guz.
Step 2: Solar Panel Specification
Highest wattage of solar panel availables in India is SHARK550W in TopCon technology and it’s efficiency is more than 22%.
| Installation Area | No. of Solar Panels | Solar Panel Wattages | Size of Solar Panels | Space (in sq. ft.) |
| 1kW | 2 | 550W | 7.47 x 3.72 | 56 |
| 2kW | 4 | 550W | 7.47 x 3.72 | 111 |
| 3kW | 6 | 550W | 7.47 x 3.72 | 167 |
| 4kW | 8 | 550W | 7.47 x 3.72 | 222 |
| 5kW | 10 | 550W | 7.47 x 3.72 | 278 |
| 8kW | 16 | 550W | 7.47 x 3.72 | 445 |
| 10kW | 20 | 550W | 7.47 x 3.72 | 556 |
Step 3: Analysis Point – Sun Direction
South Facing
Step 4: Analysis Point – Area
Plane/Flat area
Step 5: Analysis Point – Height
Average height of solar panel installation from the surface area should be 7 to 8 ft, so people can walk easily.
Step 6: Analysis Point – Foundation
A foundation of panel stand legs must be strong so solar panels can be protect from the high wind (wind speed: 160 km/h)
Step 7: Analysis Point – Angle
Solar panel angle depends on latitude and longitude area. You can check solar panel angle on google.
Step 8: Analysis Point – Water Proofing
You can install solar panels as like fiber / teen / cement sheet using EPDM tape.
Step 9: Analysis Point – Cleaning Option
You can give option to clean solar panels duing the solar panel installation from your supply water tank. You can give option to open / close water for solar panel cleaning. Sprinkler and Wiper will be required to clean solar panels.
Step 10: Analysis Point – Wiring Route
You need to think wiring route of solar panels to inverter battery to distribution board to main electricity meter. There are multiple wires come from the rooftop. Some wires go to inverter battery and some wires go to ground.
Conclusion
After reading above steps, you aware about basic need of solar panel installation on your rooftop. If you have any question, talk with our solar experts or book engineer visit to know more details.
