Topfencesolar is leading R&D and designing of solar panel roof mounts systems. We are professionally offering one-stop solar solutions. Our systems are including Flat Roof Solar Panel Mounting, Metal roof mounting system, Ground solar mounting system, carport solar system, BIPV solar roof system, and agrivoltaics solar system.
Building a solar power station directly on the rooftop of existing buildings, and there is no need to occupy additional land. It is a popular urban energy transformation solution at nowadays. Roof solar system is well combining solar structures and roof being a complete and integrated structures.

Metal roofs such as Standing seam roof, corrugate plate, etc.
Pitched tile roof bottom with wooden beam
Pitched or flat asphalt roof
Cementing type concrete roof
More categories…
1. For metal roof, measure the roof size. the system is designed based on your existing roof size details as below.
2. Topfencesolar engineer team will match the best solution for the roofs accordingly.
a. The metal roof choosing roof clamps with H rails optimized system, easy and fast installation.
b. L-feet with bolts system for the corrugate metal roof.
c. Mini Rail system optimized the structure to make the loading weight smallest.
d. Tile roofs, we could choose using roof hook /two heads bolts + rail system.
e. Flat roof mostly applied the ballast system or tripod design.
f. Tripod structure could meet different angles and high customization for better solar power generation on flat or pitched roofs.
