A+ Sun Systems develops innovative mounting systems for photovoltaic plants. Their mission is to create technological solutions that overcome application problems and achieve grid parity. Their SunNet Roof and SunNet Ground systems require no ballast, no drilling of roofs or ground, are very fast to install, ultra-light, and safe in earthquakes or typhoons. They can be used on various roof types like arched, domed, or flat roofs as well as quarry walls, landfills, and vineyards.

9. SunNet Roof :
The best performance from your panels
• Classic aerodynamic membrane forces panels
tilt at 0°-10° and limits the ventilation of the
panels
• SunNet Roof is the mounting system with No
Ballast, No Membrane Drilling, which allows a
perfect panels tilt (0-45 degrees) assuring
ideal ventilation of the panels.
• SunNet Roof allows you to obtain the best
performance from your panels

10. SunNet Roof :
Safe in case of earthquake & typhoons
• Composed by trestles tightly connected
together from north to south
• Made by East-West running cables
• Cables safely anchored to the roof
perimeter
• Unlike ballasted mounting systems,
SunNet Roof remains solidly anchored to
the roof even in case of exceptional wind

20. What we do offer:
• Solar Tensile Structure:
• Complete tensile structure (hooks and panels clamps, screws)
• Design of SunNet Roof/Ground according to the wind/snow zone
and configuration of the system in order to have cost efficiency and
be totally safe
• Pre-assembled structure to reduce installation time
• On demand:
• Customer training for a more effective installation
• Structural analysis of the building
• Analysis of the cement used in the building
• Structural tests on the building
