We speak with the distribution company SunFields Europe, they clarify this and other doubts about the different guarantees and qualities of solar panels.

Acquisition of solar panels has increased significantly in recent years, in part due to the new regulatory framework that encourages photovoltaic self-consumption, but also thanks to the growing interest of companies and individuals for the most environmentally friendly options and, of course, in the savings on the monthly electricity bill that this alternative implies.

However, never forget that not worth saving in the short term so in the long run the losses may be greater than if we had invested our money correctly from the start. Therefore, we should be wary of strangely cheap products and be especially mindful of the fine print of warranties, because as the experts at Sun Fields Europe, this may contain an unpleasant surprise that will manifest itself in the future in the worst case.

Product guarantee and production guarantee.

Solar panels are products that are expected to have a long half-life. Adding this to the fact that currently, for many consumers, the possibility of acquiring these devices is still something new; do that the buyer’s lack of knowledge of what to look for and ask for, if you want to get a good solar panel, it is much bigger than other technology products.

One of the most common mistakes is not paying enough attention to the guarantee they offer. If you do, the buyer who is unfamiliar with this product may be surprised to find that there are two different warranties: product warranties and production warranties. But what exactly are the differences?

According to experts from this Galician company specializing in solar panels, the production guarantee refers to the years in which a minimum percentage return is guaranteed. The most common is that a minimum production of 90% is promised for 10 years and 80% for 25 years.

On the other hand, the Product warranty It is applied to the solar panel and its components. This is where the confusion arises, since it normally lasts 10, 12 or 15. What is the reason for this difference?

A questionable business strategy.

This is because common sense tells us that both must last at the same time, as this does little to guarantee minimum production for a device that if it breaks outside of the product warranty period, it will become a very useful trash. or directly unusable. In fact, the production warranty does not apply if the failure is due to damaged or defective module components. Unfortunately, this is often the main reason why performance is lower than promised by the production warranty.

To find the reason for this nonsense, you just have to ask yourself who benefits from it and, as many of you may have already guessed, the answer is the manufacturer.

Manufacturers who offer a 10 to 15 year product warranty just know that it is very difficult for the device they are selling to last much longer, because its business strategy is mainly based on attracting customers through prices lower than those of the competition, at the cost of material, personnel and cost savings in the manufacturing process. This way, they get more sales without sacrificing their profit margin.

Often times, these types of tips are accompanied by other business practices that can cause headaches when making a claim. For example, changes in the manufacturing company every few years to avoid covering warranties or falsifying the origin of the module.

Cheap is always expensive.

In this case, add to this saying “and not just about money”, because if you thought that the worst thing that could happen to you with a cheap plate is to find out that you have wasted money above, be aware that at worst In most cases, there is a risk of fire.

Some of the more common shortcomings of inexpensive solar panels are hot spots, which can completely disable the device; delamination of panel cells or premature deterioration of some important module components.

So it is clear that you don’t have to skimp on purchasing any of these devices. We must pay particular attention to product and production guarantees, and always require that both cover a minimum period of 25 years.
