Ballast 20°

20° Ballast is one of the most used when high inclinations are preferred to maximize the production of photovoltaic systems. It can be installed on all types of surfaces: green roof, sheath, concrete or pavement, ground, etc. thanks to the fact that it must not be fixed and thanks to its weight guarantees a strong wind resistance. An excellent choice in cases the inclination must be high but the plant is located in a very windy area.

ZAVORRA 20°

Sun Ballast 0 ° fixing system is realized of vibrated and reinforced concrete and allows an inclination of 20 °. The material with which the ballast is made has an exposure class XC4 as well as a resistance class of C32 / 40.

It performs both the function of support and ballast to the photovoltaic panels and must not be fixed on the roof but only supported. During installation, a rubber protective sheath is placed between the support and the cover.

The photovoltaic panels are hooked onto the support equipped with an M8 bushing by means of special central clips and the orientation of the module can be horizontal or vertical.

Yes, our system can be installed on membranes, paved surfaces, gravel, green roofs and on the ground.

Yes, if necessary, our ballast can be drilled in the central areas to insert expansion anchors with a diameter of 9 mm.

Yes, our technicians will recommend the best solution after reviewing the panel’s technical data sheet and installation instructions.

Yes, they can be installed using mounting rails.

Once we receive the completed order—that is, the signed order, the delivery address and payment—we arrange shipment with the following estimated delivery times: 2–3 business days for Northern Italy, 3–4 business days for Central Italy, 4–5 business days for Southern Italy and the islands, and 5–6 business days for other countries.

Yes, certainly. We can arrange a vehicle equipped with a hydraulic tail lift to unload up to 15–20 pallets at ground level.

It can be installed on a roof with a slope variation ranging from +5° to -5°.

Yes, the system can be prepared for grounding using the plates supplied upon request, or by creating an electrical connection between the panels in accordance with standard installation procedures.

Yes, it is possible, with a minimum order quantity of one pallet.

Yes, our ballasts contain one or two steel reinforcement bars to withstand handling. This means that if a ballast is damaged during transport—for example, if it has hairline cracks around its circumference—it can still be used.

No, it is made of galvanised steel, as this material allows the thread to be re-tapped during installation using an M8 tap.

Apply a lubricant, such as WD-40, or grease to the insert.

Our insert has an effective thread depth of approximately 3 cm.
