We live in a country where everything that is not immediate, day to day, seems to have no meaning. Planning is an issue that most of the time catches us off guard, and when we reach retirement age, we curse the day we decided not to have a good pension plan for it, or to have paid the minimum to save a few euros.

Well, that moment always comes, and if you treat equipment and machinery with care and act on it when it is necessary, you will not have to regret that they do not last or that they break down every now and then, spending much more money than if you had taken the trouble to carry out scheduled maintenance when it was due.

 It may seem that a photovoltaic solar system does not need maintenance, just cleaning it from time to time is enough. Well, a photovoltaic solar system, although it does not need such exhaustive or punctual maintenance as that of an internal combustion engine, we will avoid many problems if once or twice a year a qualified technician checks the system, not only cleaning the solar panels; there are connections, cables, boxes, inverters, in some cases batteries, regulators and control and monitoring systems. Specialized magazines in the sector such as PV Magazine, in an article from a few months ago, warn that losses due to lack of maintenance in self-consumption photovoltaic installations, that is, the simplest in the sector, are 8.8% annually, all this without taking into account the premature deterioration that poor maintenance entails and the possible indirect collateral implications that very frequently occur, which can raise losses to more than 10%. While the cost of maintenance is on average 5% of the cost of the installation per year, and with the peace of mind and security that this gives, knowing that the installation performs at 100% of what it is expected to perform, making it an efficient installation with little chance of costly repairs or failures. We recommend reading this other article that we wrote some time ago about the maintenance of solar panels .

If we move on to the field of isolated photovoltaic solar installations, that is, without connection to the electrical grid, then the issue of maintenance is already an issue that becomes imperative, since we not only have panels, connections, inverter, etc. Here there are more critical elements for which poor maintenance can cause us a lot of trouble and significant economic losses. Although the issue of lithium batteries has alleviated this aspect, since they do not need as much maintenance and care as traditional acid/lead batteries, the system continues to need maintenance and care; and if we talk about the generator in these isolated electrification systems, in which it is necessary and essential, then maintenance between one and two times a year is mandatory, otherwise, we are no longer talking about having scares or losses, but rather some other misfortune.

In conclusion, preventive maintenance in solar and/or isolated installations, not to mention aerothermal systems, is necessary and economically profitable. There are renowned brands of aerothermal equipment that, if they have a scheduled maintenance system, extend their warranty up to 15 years, on parts and labor, so that at least during these 15 years, if you have had scheduled maintenance, you can rest easy.

One of our main activities in the sector of photovoltaic solar installations, isolated power supply systems, aerothermal energy and generator sets, is precisely their maintenance, and their care so that they produce and work properly, and without problems.
