A bidirectional ballast system for fixing solar panels on a flat roof

Ballast PV system is a supporting structure for photovoltaic modules, which are placed on the roofs of industrial, commercial and private buildings. The system allows the installation of solar panels on flat roofs ballastly without anchoring and compensate for the roof angle when necessary.

The ballast mounting system is available, easy to install and does not damage the main waterproofing rug, which prevents leakage or damage to the roof during operation.

Unlike the unidirectional ballast, this system has a bi-directional arrangement of solar panels (PV), to the east and west, allowing the solar station to have high performance during the day.

Advantages of ballast solar stations

  • Does not require mounting to the roof.
  • Due to its special construction and special substrates it allows even the load on the roof to be evenly distributed and to avoid damage and deformation of the heater and roofing.
  • Keeps the integrity of the roof, does not damage the surface.
  • Increased resistance to atmospheric influences.
  • Small weight and high stability.
  • Convenient and reliable installation.
  • Supporting triangles and mounting elements are already in stock.
  • Save time of installation, effort and money.

Universal systems for mounting PV modules, allow the installation of solar panels on roofs of buildings or other structures that have sloping roofs, or the roof at an angle. This is a set of designs that directly from the package allow you to mold and mount your own solar station.

Ballast mounting systems are specially designed for roof PV panels that need to be placed on a flat roof of a home, a production or a warehouse complex. Systems do not damage the waterproofing rug, due to the lack of need for anchoring or depressurizing the roof.

Facade solar stations - as a solution, it only gets its heyday. Very convenient way to mount sunshine, where it is possible to fasten photo panels to brick, concrete and other roofs, at an angle or in parallel.

Special, water protection systems are able to remove rain precipitation, so it is advisable to make a canopy, under which you can place a car or arrange a warehouse.

Ground solar stations are built on free areas of land, concrete, crushed stone or sand. When it is impossible to mount the station on the roof of the building or there is no reliable foundation. We deliver ready-made kits that are individually tailored to the customer.
