FAQ QUESTIONS AND ANSWERS: Plastic brackets for photovoltaic
It is understandable to have doubts when you come across an innovative product and different from those traditionally used, such as Nexus plastic brackets for photovoltaic panels. They represent a real revolution in the field of renewable energies.
Our team is ready to answer all your questions, but here you can find the most frequent questions many installers ask us.
Are the systems certified? What guarantee is recognised?
All our fastening systems have been tested according to the current regulations in 2009, when they were introduced on the market, and in 2023, to update the tests to the current regulations.
The recognized warranty is the commercial standard of 2 years, but it can last up to more than 20 years.
You can contact us to request the documentation.
Have you already made implants with your brackets?
Certainly. The project was born in 2009 at the request of an Anconetano installer who reported the most common problems during the installation. Since that year we have sold thousands of brackets without ever having encountered any kind of problem. All the customers who have given us their trust have then bought several successive times.
The success of almost twenty years demonstrates the solidity of the project, which thanks to consistency, quality and innovation, has been able to win and maintain the trust of a more demanding public.
Plastic breaks easily and it is not weather resistant
Attention! The plastic term is not synonymous with low quality!
Commonly plastic is associated with products not very durable but when we talk about technical items we must emphasize the existence of various types of plastic material: from the waste, cheaper and fragile (a few cents per kg) to the most expensive and efficient (over 10€ per kg).
Our brackets are made of a high quality plastic material: Nylon, or Polyamide, glass fiber loaded to 30%. The same type of material is used in the automotive sector for components that reside in the engine hood. There is a wide literature showing that the material is perfectly capable of withstanding very high thermal stresses and major mechanical stress.
Plastic material is also, compared to various types of metal, not affected by salt corrosion in places near the sea and/ or other atmospheric agents.

Are they not likely to be lifted in case of strong winds?
The particular structure of our brackets ensures that they are anchored directly to the corrugated sheet or sandwich panel, guaranteeing total insulation to the photovoltaic module (in the case of steel or aluminium brackets, contact between different metals can corrode the parts concerned and expose them to dangerous temperatures).
Plastic pollutes, is not ecological...
Due to the growing climate and environmental concern of recent years, plastic has acquired the label of not sustainable. In reality it is not the material itself that is polluting but its production and form of disposal.Once the service life of the brackets is over, they can simply be ground to recover material and give life to new recycled products!
In summary, why prefering plastic brackets to steel ones?
- Lightweight and easy to carry on roofs- Minimal footprint if you want to have stock in stock- Less long-term corrosion exposure, especially in areas prone to sea salt- Lower temperature in the contact between panel frame and bracket- Cost reduction- Industrial production of the least polluting material
