The Pisko Solar solar panel brackets are carefully tested to be safe and easy to use. Solar panels are often subjected to stress from several external factors, such as snow and wind loads. It is important that the static load resistance of the products has been tested and specified. This is the starting point for a safe environment and a functional long-life roof. The durability of the Pisko Solar brackets has been tested for each roof type 1) directly from the fastening surface out and 2) in the direction of the incline of the roof.

Solar panel systems are often comprised of components made of different metals and metal alloys – a thick and strong paint coat on roof fasteners provides the required isolation between metal surfaces to substantially reduce the risk of galvanic corrosion. Piristeel manufactures Pisko Solar brackets using high-strength galvanized steel that is always powder-coated to maximize the corrosion protection. It is difficult to inspect the condition of roof brackets under solar panel fields, and therefore it is of paramount importance for the products to be maintenance-free and durable. Pisko Solar endures on any roof.


No compromise in terms of the fastness or watertightness of the fixtures.

Pisko Solar roof brackets are extremely strong. At the same time, the brackets are highly resistant to deforming. Brackets that endure wind and snow loads without bending boost the life of a roof significantly and keep the roof covering functional and watertight. Individual Pisko Solar brackets endure static pulls of up to 4.5 kN straight away from the fastening surface. As a system, the durability is multiplied as the number of brackets and size of the solar panel field increase.

Pisko Solar roof mountings are made using watertight methods. Proprietary Pisko 2+1 sealants (download Pisko 2+1 seal brochure) that are quick to install while offering complete watertightness have been developed for batten mountings. Pisko rubber gasket pairs are used for the required elevations. Products of the Pisko UniSeam family are used for fastening seamed roofing. UniSeam offers a significant benefit with regard to minimizing the load on the roofing material and paint coat and keeping the roof covering clean.


Pisko Solar roof bracket range

The Pisko Solar roof bracket range includes 4 bracket models

  • Pisko Solar bracket, Pisko UniSeam: for snap-lock and mechanically seamed roofs
  • Pisko Solar bracket 425: for profiled sheet, bitumen, PVC and tile sheet roofs
  • Pisko Solar bracket, tiled roof: for tile roofs
  • Pisko Solar bracket, flat roofs: for e.g. bitumen and PVC roofs


The brackets make it possible to fasten the solar panel fastening rails from the underside or from the front on the eaves side. Particular attention has been paid to the ease of installing the products using alternative fastening methods and to the rounded edges of the products.

Technical declarations for Pisko Solar brackets

Piristeel declares values for the durability of its Solar products. There is no standard that sets any minimum requirements for the mountings of solar panel systems. Therefore, there are also products with no declared durability value in the market. Piristeel has tested the Pisko Solar products so that clear-cut values can be specified accurately for the durability of the products. The durability of individual Pisko Solar roof brackets has been tested in static tests by mechanically loading the products. The load tests have been made perpendicular to the fastening surface and in the direction of the roof pitch. Pisko Solar brackets are fitter-friendly, durable and long-lived. Pisko Solar makes it possible to use solar energy without concerns or any damage to the roof covering.
