What to pay attention to?
Support structures are chosen at one of the first stages of planning an investment in a photovoltaic system. Before making a decision, it is worth asking the fitter or technical and commercial advisor whether the proposed structure meets the applicable standards, is certified, and comes with a guarantee. This stage is often overlooked by investors. You should realise that although the support structure seems to be the least technically advanced component of the photovoltaic system, it is very important because it must ensure failure-free and maintenance-free operation for a long time. The support structure is exposed to adverse environmental conditions such as high and low temperatures as well as wind, rain, and snow.
Components from proven manufacturers
When choosing components, it is often relying on an experienced contractor with relevant references. Attention should also be paid that the contractor offers components from proven manufacturers, whose products have been available on the market for a long time. This guarantees that the manufacturer will not suddenly disappear from the market, leaving the customer without after-sales support. The country of manufacture of such support structures also matters. Why does it matter? If you need to make a warranty claim, it makes the formalities much simpler. A comprehensive range of products and equipment necessary to operate a photovoltaic system can be found in the “Our Offer” tab and the Corab e-warehouse.
In a guarantee, longer does not necessarily mean better
Caution is needed when choosing a photovoltaic design based on the length of the guarantee. Both too long and too short a warranty should arouse the suspicions of the investor. It is an unfair, but unfortunately, very common practice, to offer a very long guarantee with no intention to observe it over such a long period because the company plans to disappear from the market in the next few years.
