Breakdowns 24h Solar panels Costa Blanca
Some of the problems that usually cause the typical cheap solar panels, in the short or medium term (3-4 years) and that we encounter daily in our work:
- Hot spots, or ‘hotspots’, due to poor quality of the solar cells used in the assembly of the product. The consequence is, in the medium term, an unusable solar panel and the obligation to buy a new one.
- Destruction of the Tedlar: Due to the low quality of many manufacturers, degradation and destruction of the Tedlar (the back of the solar panel) often occurs due to a hot spot. It will also cause the panel to become unusable.
- Delamination of the solar cells integrated in the panel. This is due to faulty manufacturing when making the laminate and will eventually cause the panel to be unusable.
It is a case that happens a lot with Asian manufacturers of medium-low quality, because the lamination process requires waiting time and, in many cases, these manufacturers shorten it to increase manufacturing at the cost of these problems occurring later. - Problems with bypass diodes. Whenever possible, ask about the type of bypass diodes used in the panel junction box. Military bypass diodes are ideal, as they are much better able to withstand high temperatures and extreme conditions. It is also important that they are well encapsulated (covered by protective silicone). There are many cases of low quality diodes that sooner or later cause them to burn out and the panel stops working.
- Yellowing of the EVA. Another very common case in cheap panels of Asian origin. The EVA used in these cases is of very low quality and with the passage of time it degrades and causes a great loss of production.
- Defective welds. Sometimes it happens that the welding process is not optimized, also that the welding temperatures are incorrect. This can cause the appearance of a hot spot, with the consequent failure of the panel and be unusable for obtaining energy from it.
- Changes of manufacturing company to avoid covering warranties. Did you know that it is a very common practice, generally in Asian manufacturers, to manufacture under a brand name but change the company that manufactures those panels every few years? The reason is to avoid covering warranties when there is a claim. If the company that manufactured the panels no longer exists, …. the warranty no longer exists.
- Sticker manufacturers. This is one of our favorites, they are the well-known manufacturers that do not manufacture. That is, companies that create a brand, which are sold as a European product, but they are neither manufacturers nor their product is European. They simply buy a cheap panel from a third party, put a sticker with their brand on it and “off they go”. Real as life itself and, unfortunately, very frequent.
