ISOTRAP Mini, S and XLA are used on trapezoidal and sandwich roofs, and ISOTILE on tile roofs; ISOBEAM is the full-length rail profile used together with ISOTRAP XLA.

ISOTRAP Mini is for landscape panel orientation only, requires a rib spacing of 285 mm or less, and is the lightest solution at about 0.45 kg/m². ISOTRAP S is a section profile in lengths of 290, 385 and 540 mm; it comes in four heights (S20, S50, S60-NX and S85), weighs about 0.8 kg/m², and, except for S50, is suitable for both landscape and portrait orientation. ISOTRAP XLA combines the XLA bracket with an ISOBEAM profile of 1,050-6,050 mm in length (30, 45, 60 or 85 mm in height), adds extra strength to the roof, and weighs 1.4-2.4 kg/m².

If you want to install the panels in a single direction facing south, ISOFLAT S13 is suitable; if you want an east-west (dual-direction) layout, ISOFLAT D13 is suitable. ISOFLAT D13 is used for flat roofs with an east-west layout.

ISOFLAT S13 places the panels in a single direction at a 13° south tilt and aims for maximum single-direction energy yield. ISOFLAT D13 combines two rows of panels back to back in a single symmetrical structure with a 13° east-west tilt; it uses close to 100% of the roof surface and provides balanced production throughout the day. Both are secured with ballast without penetrating the roof and are tested in the I.F.I. Aachen wind tunnel; the final selection is made project-specifically according to the roof dimensions, weight limit and production profile.

ISOGROUND TWO is a fixed-tilt, double-column ground-mount system that can be installed on any soil type using driven piles, concrete foundations, pipe-supported driving and anchoring methods.

The steel-steel (SS) variant is the main variant for project-based installations of 500 kWp and above; the steel-aluminum (SA) variant, with aluminum purlins that can be cut on site, is preferred for applications such as agricultural irrigation. The load-bearing elements are made of high-strength ZM-coated steel (S350GD + ZM310), the panel tilt is between 10° and 30°, and the design life is 25 years (C3/C4 corrosion class). The right method for the soil type is determined by the geotechnical report. The single-column ISOGROUND ONE is preferred to reduce the number of columns on hard ground.

Yes, if beams, purlins or cables shade the rear side of the panel, the additional yield of a bifacial panel is reduced; for this reason ISOTEC offers the BF bracket, which leaves a 56 mm gap between the purlin and the panel.

According to ISOTEC pages, bifacial panels typically provide 15-20% additional yield; in systems without the BF bracket, purlin shading can cause a loss of about 6-8%. In ISOTEC's own simulation (NREL Bifacial Radiance, 8760-hour TMY2 data, 0.50 albedo), the bifacial gain was 18% with the BF bracket and about 10-12% without it. These are ISOTEC simulation results, not field measurements. The BF bracket is offered with BFC, BFC-E and BFC-SET clamp options for glass-glass panels.

A section profile provides better air circulation than a full-length profile and is about 20% more economical.

With a full-length profile, heat stays trapped between the rails and blocks air circulation. Because circulation is more effective with a section profile, it also offers an advantage in energy yield.

Yes, the ISOTRAP S section profile solution is compatible with all rib spacings thanks to its different length options.

A rib is the raised ridge (crest) on the surface of trapezoidal or sandwich panel roofing; the rib spacing is the distance between two adjacent crests. During the site survey, you simply need to tell our specialist teams the rib spacing. We offer different length options such as 290 mm, 385 mm and 540 mm.

When choosing a panel, wattage, dimensions, brand, material quality, warranty period, certificates and price should be evaluated together.

A panel that does not fit your budget is of limited use to you, no matter how superior its features are.

Monocrystalline solar panels are one of the most preferred options because of their high efficiency.

Monocrystalline panels save space thanks to their high energy conversion capacity; their durable, long-lasting construction is another reason they are preferred.

No, we do not supply solar panels.

With ballast (weight) fastening, the building height can be at most 20 m for ISOFLAT S13 and at most 30 m for ISOFLAT D13.

For taller buildings, methods such as anchoring or parapet attachment are considered. The wind tunnel coefficients have been derived for roof slopes up to 10° and building heights up to 50 m.

Related pages: ISOFLAT S13, ISOFLAT D13.

Yes, side wind deflectors turn the panels into a fully enclosed system so that they are less affected by wind, and can reduce the required amount of ballast by up to about 5%.

Related pages: Flat Roof Systems.

Yes, in the ISOFLAT S13 (south-facing system) mounting system the rear wind deflector is a standard component and is included in the installation steps.

The wind tunnel test and the required ballast calculations are valid under these conditions. If the rear wind deflector is not installed, the solar panel is directly exposed to the wind, high wind forces occur and the system lifts more easily. The right and left side wind deflectors are optional.

Related pages: ISOFLAT S13.

In ISOFLAT D13, the panels are placed back to back in the east-west direction and shield each other from the wind, so much less ballast is required than for ISOFLAT S13.

In ISOFLAT D13, the panels are placed in an east-west (left-right) configuration.

Related pages: ISOFLAT D13.

Wind has two effects on a panel, uplift and sliding; ballast is used against both, and the special rubber material between the system and the roof surface increases friction, that is, sliding resistance.

Related pages: ISOFLAT S13, ISOFLAT D13.

On flat roofs, water drainage is ensured by the natural slope of the roof, generally 1-3%, and the rubber pad under the ISOFLAT rails does not obstruct water flow.

The special SBR rubber products used under the rails are offered in different heights.

Related pages: ISOFLAT S13.

With ISOFLAT S13, the gap between panels can be selected as 50, 60, 70 or 80 cm; with ISOFLAT D13, the gaps between panels are fixed.

Related pages: ISOFLAT S13, ISOFLAT D13.

In ISOFLAT systems each array is at most 15 m (thermal expansion limit), at least 550 mm of distance is left from the roof edge, and if the roof slope exceeds 3%, the system is additionally secured to the parapet with a steel cable.

These values appear in the technical data on both the ISOFLAT S13 and ISOFLAT D13 product pages; the ballast load for each site is calculated separately for the specific project.

Related pages: ISOFLAT S13, ISOFLAT D13.

Yes, depending on the height of the parapet it affects the system; for this reason parapets are taken into account when calculating ballast for flat roof systems.

Yes, the closer the panels are to the surface, the more aerodynamic the system is; being high above the surface poses a risk because the panels would be exposed to more wind.

Air circulation under the panels is important for energy efficiency; leaving a gap of 3-8 cm above the roof covering is sufficient for natural circulation.

Moving the panels too far from the roof covering increases the effect of wind. For this reason, a region-specific height is chosen using the right calculation method (Eurocode) and the right product selection.

If you have the datasheet of your roof covering, the load it can carry per m² is reviewed; all loads on the roof are calculated, and if the load limit is not exceeded, installation on the roof is possible, and if it is exceeded, the system is fastened to the purlins.

All loads acting at the roof's location are calculated to determine the load per m², which is then compared with the load the covering can carry.

ISOTRAP systems add roughly 0.45 kg (ISOTRAP Mini) to 2.4 kg (ISOTRAP XLA) per square meter to the roof.

According to the product pages, ISOTRAP Mini weighs about 0.45 kg/m², ISOTRAP S about 0.8 kg/m² and ISOTRAP XLA 1.4-2.4 kg/m². For ISOFLAT systems on flat roofs, the ballast weight is calculated separately for each project according to the wind load.

For maximum yield, special attention should be paid to tilt and shading; in Türkiye, the system should ideally be installed at a tilt between 15 and 30 degrees.

Choosing the right tilt is a critical factor in maximizing panel performance.

In the northern hemisphere, for example in Türkiye, panels are positioned facing south for the best performance; in the southern hemisphere, they face north.

A tilt of 15-30 degrees is generally recommended for a fixed tilt year-round; for seasonally adjustable setups, about 15 degrees is recommended in summer, about 30 in spring and autumn, and about 45 in winter.

A 45-degree tilt in winter is recommended to reduce snow accumulation and capture sunlight best.

A slope of at least 2 percent (1.1 degrees) is recommended for flat roofs; the ideal slope is stated as 5 percent (2.9 degrees).

The German Building Code contains no definitive information on flat roof slopes; these values are based on the German Flat Roof Directive. Flat roofs are preferred especially in buildings where low-slope roofs are common.

Yes, ISOTEC calculates wind and snow loads for your project based on TS 498 and Eurocode; the values are taken according to the project location.

On flat roofs, the ballast (weight) calculation is produced in kg for each panel; the inputs are building height, peak wind pressure (qp), parapet, roof slope and friction coefficient (0.5 for concrete, 0.3 for membrane). For Germany, DIN EN 1991-1-4/NA and I.F.I. wind tunnel coefficients are used. The required ballast in kg/m² varies by project and is provided with the structural report at the quote stage; there is no general fixed value. For modules that the calculation shows are not suitable for ballast fastening, anchoring or IMC is recommended.

6063-T66 aluminum profiles are used in roof systems for light weight and easy installation, and high-strength ZM-coated steel is used in ground-mount systems for load-bearing columns and beams.

In the steel-steel variant of the ISOGROUND TWO ground-mount system, all load-bearing elements are ZM-coated steel; in the steel-aluminum variant, only the purlins are aluminum. The ZM coating's self-healing property at cut edges is an advantage for steel profiles that are cut and drilled on site.

Related pages: ISOGROUND TWO, ZM-Coated Steel Technology.

6063-T66 is the code of the aluminum alloy ISOTEC uses in its rails and clamps; A2-70 is A2 stainless steel with strength class 70, used in fasteners.

6063 indicates the alloy number and T66 the heat treatment condition. The A2-70 grade defines stainless fasteners according to EN ISO 3506. The ISOFLAT, ISOTRAP and ISOGROUND product pages specify 6063-T66 for profiles and clamps and A2-70 for fasteners.

ZM is a zinc-aluminum-magnesium (Zn-Al-Mg) coating defined in EN 10346; it is applied continuously during production and self-heals at cut edges, whereas hot-dip galvanizing (HDG) is the dipping of the part into a zinc bath after production and leaves the cut edge unprotected.

In the composition of the ZM coating, the total of Al and Mg is 1.5-8% and Mg is at least 0.2%. Because solar power plant structural members are cut and drilled by laser, plasma or shears, edge protection is important; ZM-coated steel (S350GD + ZM310) is used as standard in ISOGROUND TWO.

Related pages: ZM-Coated Steel Technology, ISOGROUND TWO.

The indicative field life for ZM430 is more than 50 years in C1 and C2, 40-50 years in C3, 20-40 years in C4 and 10-20 years in C5; for ZM310 it is 30-50 years in C3, 15-30 in C4 and 8-15 in C5.

The number indicates the total coating mass: ZM310 is about 310 g/m² (about 24 µm per side), ZM430 is about 430 g/m² (about 35 µm per side). These periods are given on the ZM page as expected field performance; they are not a contractual warranty period.

Related pages: ZM-Coated Steel Technology.

In industrial or moderately saline environments (C4), the indicative life for ZM430 is 20-40 years; in highly saline and aggressive environments (C5), it is 10-20 years.

According to the specification on the ZM page, in a C5 environment the warranty depends on the duplex system (ZM coating plus paint); pure ZM430 alone is not covered by a C5 warranty. Continuous contact with seawater and soil is outside the scope of pure ZM. The environment class is determined according to the ISO 9223 category of the project site.

In ISOFLAT, an aluminum-laminated SBR rubber membrane is used between the rails and the roof; the membrane does not damage your roof.

On membrane roofs, the SBR rubber is placed so that its aluminum side faces the roof membrane. EPDM, on the other hand, is the gasket material of the ISOTRAP trapezoidal and sandwich systems.

Related pages: ISOFLAT S13, ISOFLAT D13, ISOTRAP Mini.

Where aluminum, steel or stainless steel come into contact, an intermediate insulator, bimetal part, suitable coating, intermediate gasket or water drainage detail is used to reduce the formation of a galvanic couple.

The main ISOFLAT load-bearing members are aluminum 6063-T66 and the fasteners are A2-70 stainless; ISOTRAP systems use stainless A2-70 and bimetal fasteners. In ground-mount systems, the points where steel, aluminum and stainless parts join are monitored during maintenance checks for oxidation, loosening and water accumulation.

A wind tunnel test is a test performed to determine the behavior of a structure under wind loads.

Because no regulation specifies how much wind load acts on a solar panel on flat roofs, a wind tunnel test must be performed in order to design a flat roof mounting system. ISOFLAT S13 and D13 were tested in the I.F.I. Institut für Industrieaerodynamik (Aachen) wind tunnel in Germany.

Related pages: ISOFLAT S13, ISOFLAT D13.
