The often forgotten element is also one of the most critical. Although, the solar panel mounting system doesn’t produce or convert energy, it does secure the solar panels in position for the anticipated lifetime. Therefore, how do Schletter solar panel mounting systems rate as a key component for your next solar project


Often describe as over engineered, others would argue that anything less is a risk. What Schletter has produced with it’s range of solar mounting accessories is a product constructed to exceed expectation in variable environments.

Unlike most alternative solar mounting systems, Schletter utilises a proprietary locking system for rail connection between solar panel clamp and rail connection between roof bracket. The locking system once set is one of the most stable platforms for securing solar panels. Incorporating an internal stainless steel nut and bolt design less likely to loosen when compared with other alternative generic designs.

Once installed many end users are concerned about the safeguarding of the solar panels and solar system against theft, especially when outlaying a considerable amount of money for premium solar panels. Schletter solar mounting system clamps incorporate a Torx T40 tamper proof stainless steel bolt head.

Although not completely tamper-proof, it’s often far greater security than the common H40 headed bolts utilised in the majority of alternative solar mounting systems. H40 is also the equivalent of a common 6mm or 1/4 inch Hex or Allen key.

Considering both internal T40 bolt and nut of the Schletter solar mounting system is stainless steel, once torqued into position the nut and bolt virtually lock together due to the stainless steel properties. Ensuring that in most cases even a T40 bit cannot always undo what it done up in the first place. Due to such a rigorous locking nature clamps incorporating stainless steel elements often cannot be reused if undone as they often separated unwillingly.


Schletter solar mounting systems, if specified correctly, are adaptable to virtually any roof surface. Including the most obscure. One mounting bracket can often facilitate the options for both landscape or portrait solar panel orientations, or even a configuration of both without detriment to the final product.

Superior engineering talent has orchestrated every component to ensure adaptability and unrivalled strength for the most testing conditions. Homeowners have choices within choices, even if space is limited, for a desired solar panel layout and result. You will not find a more adaptable, reinforced solar mounting system on the market of such purity.


Incorporating ultra high-quality aluminium and stainless steel (304) componentry (1.4301). A Schletter solar mounting system ensures your solar energy system is built better than most with strength test verifications by the most stringent EU certifications.

Production operations subjected to TUV Rheinland CERT:

  • ISO 9001:2008
  • ISO 14001:2004
  • ISO 50001:2011

EG certification in accordance with:

  • DIN EN 1090-2/3 EXC3
  • DIN EN ISO 3834-2:2006 – Extensive demands on quality in welding operation

Manufacturer qualification in accordance with:

  • DIN 2303 Q2 BK1
  • DIN EN 15085-2 – Certification level CL1
  • DIN V4113-3 class C

What does the above mean? It is proof that Schletter solar mounting systems have conformed to some of the highest testing standards for solar mounting systems in the world. Want to test an alloy or stainless purity for yourself? Without proof of high-intensity testing, do one simple thing, get a strong magnet, hold it to a non-alloy metal surface, the harder it sticks, the least pure it is.


A  respectable 10-year product warranty in line with the industry average of product guarantees for solar panel mounting systems.  It is worth noting that one should not confuse warranty and life expectancy. Schletter solar panel mounting systems extended structural integrity is largely the subject of how and where it is installed. Following installation is performed inline with the comprehensive installation specifications provided by the manufacturer one can be assured a lifetime of solar panel structural security.


As one of the better engineered solar panel mounting systems and manufactured from superior-grade materials, one must expect to pay a premium for a high-calibre product. However, in the context of the entire investment, the additional expense for a far superior product can be viewed as minimal (depending on the nature of the installation). 


Considering any alternative is a concession on both quality and strength. The weakest point of every solar energy system is the point where the solar mounting system connects to the roof. Ignore that fact at your own risk. Marketers and sellers will often gloss over such importance and force your concentration elsewhere. Schletter, without a doubt, sits on its own at the top of the table in rooftop solar mounting systems, nothing else comes close.
