APL Apollo Solar Structure | Authorized Distributor

1. Do Loop Solar structures meet PM Surya Ghar scheme standards?
Yes. The PM Surya Ghar: Muft Bijli Yojana mandates structures capable of withstanding high wind speeds (typically 150-170 km/h). Loop Solar supplies APL Apollo HDGI and GI structures that adhere to IS 2062 structural steel standards, ensuring full compliance for subsidy approvals.

2. What APL Apollo C-Channel sizes are available for bulk orders?
Loop Solar stocks two primary APL Apollo profiles: 80x40x15 mm (2 mm thickness) for heavy-duty rafters and 40x40 mm (2 mm thickness) for purlins. Both are available in 12.5 ft, 16 ft, and 21 ft lengths to minimize wastage.

3. What is the difference between HDGI and GI Rafters?
HDGI (Hot Dip Galvanized Iron) rafters are dipped in molten zinc after fabrication (80+ microns), offering superior corrosion resistance for coastal areas. GI (Pre-Galvanized) rafters are made from pre-coated steel sheets and are cost-effective for inland use. Loop Solar supplies both variants.

4. Which Monorail sizes are available for tin shed roofs?
For non-penetrative or short-rail installations, Loop Solar provides Monorails in: 31x70x300 mm, 31x60x300 mm, 31x41x300 mm, and 31x100x300 mm. These are ideal for industrial tin sheds and come with EPDM compatibility.

5. Which clamps fit standard DCR panels for the subsidy scheme?
Most DCR panels (like Adani or Waaree) use 30mm or 35mm frames. Loop Solar stocks universal Mid Clamp (30mm & 35mm) and End Clamp (30mm & 35mm) sizes to ensure a secure fit for these government-mandated modules.

6. Why use Spring Nuts and Rail Nuts?
Spring Nuts (MS) and Rail Nuts are designed to lock into the grooves of our slotted C-channels. They allow for rapid, slip-free fastening of solar panels without the need for welding or drilling on the roof.

7. How do I extend the length of rafters for large roofs?
Loop Solar supplies specialized Jointers (Rafter) and Jointers (Purlin). These components allow you to mechanically connect two lengths of C-Channel securely, maintaining structural integrity across large rooftops.

8. What fasteners are included in a standard Loop Solar kit?
We provide a comprehensive range including Nut Bolt Washer 3x8x1 Inch (SS304), M10 Fasteners, and Allen Key Bolts. Using SS304 grade fasteners is critical to prevent galvanic corrosion.

9. How are the structures anchored to concrete roofs?
We supply high-strength Anchor Bolts which are drilled into concrete ballast blocks or the RCC roof itself. These are used in conjunction with our Base Plates to secure the legs of the structure against wind uplift.

10. What are Degree Hangers used for?
Degree Hangers (35mm and 70mm) are used to create the necessary tilt angle for solar panels on flat tin sheds or industrial roofs. Correct tilting maximizes energy generation and aids in self-cleaning.

11. Do the Slotted Purlins require on-site drilling?
No. The HDGI/GI Structure Purlin Slotted 41x41x2 (Apollo) comes with pre-punched slots. This eliminates the need for on-site drilling, speeding up installation and protecting the galvanized coating.

12. Is EPDM included for waterproofing?
Yes, EPDM rubber strips are available with Loop Solar. They are essential for placing under Monorails and clamps to ensure a watertight seal on the roof.

13. Are Base Plates sold separately?
Yes, Loop Solar supplies independent Base Plates. These distribute the point load of the structure legs over a larger area, protecting the roof surface.

14. Can these structures support Bi-facial modules?
Yes. Our RCC-Max and RCC-Super designs using the heavy 80x40x15 rafters provide high ground clearance (up to 4m), which reduces shading on the back of bi-facial modules.

15. Why choose factory-made structures over local fabrication?
Locally welded mild steel rusts quickly. APL Apollo structures from Loop Solar are factory-galvanized to IS standards, offering a 25-year structural life that matches the warranty of premium solar panels.

16. When are Rivets used in installation?
Rivets are used for attaching short rails or components to metal sheet roofs where you cannot access the underside. Loop Solar supplies high-strength rivets for secure sheet metal attachment.

17. Can the rafters support 550W+ large format modules?
Absolutely. The 80x40x15 mm Rafters are engineered to handle the increased static load and surface area of modern 550Wp+ modules without sagging.

18. What tools are required for assembly?
Since our system uses Slotted Purlins, Spring Nuts, and Allen Key Bolts, no welding is required. Standard wrenches, a drill for anchoring, and an Allen key set are sufficient.

19. How fast can Loop Solar deliver these components?
With warehouses in major hubs like Gurgaon and Bangalore, Loop Solar typically dispatches bulk orders of APL Apollo Channels and Fasteners within 24-48 hours.

20. Can I order a complete customized kit?
Yes. Share your roof layout with Loop Solar, and we will bundle the correct length of Channels, Clamps, Jointers, and Fasteners into a single shipment customized for your project.
