We usually consider that solar panels do not have any disadvantages, since they are an ecological and economic element in the medium and long-term. And much of this is true, however one should think about why many buildings, whether homes or businesses, do not yet have this system.
The reality is that we have more advantages than disadvantages, however, it would be good to consider the advantages and disadvantages of solar panels to consider whether installing them in our properties is worthwhile.
Advantages of solar panels:
- The use of solar energy has the great benefit of the healthy conservation of the environment.
- Solar energy is not only a form of sustainable energy consumption but infinitely renewable.
- Solar panels need little maintenance, as they do not have mechanical parts that can fail.
- Its conversion of solar energy into electrical does not imply acoustic contamination, the process is ecological and there is no noise involved.
- It is possible to help from savings of up to 85 percent on the electricity bill when switching from normal electricity to solar water heaters.
- Low cost of use. The only cost associated with the use of solar energy is the manufacture of its components and installation, since after the first investment there are no more costs associated with its use.
- The boost that a country’s economy receives when it implements this type of clean energy.
- They do not produce greenhouse gas emissions, they are inexhaustible and have many applications, both domestically and on a large scale.
- Solar panels are adaptable to the needs, solar energy systems designed to be flexible and expandable, so it is possible to do a quality and performance test in a smaller area and then decide if you want to do an expansion.
- The advance of this technology has been so great that not only the sunlight collector systems, but also the solar radiation, which means that it is not necessarily a sunny day to take advantage of the sun’s energy.
Disadvantages of solar panels:
- Meteorological dependence. One of the disadvantages of solar energy is that it produced at night. Despite this, there are some models that are capable of accumulating and storing so much energy that, at the time of nightfall, that energy is still available. Even, there are some panels that perceive the light of the moon, like the solar panels.
- Both its purchase and its installation may represent a large first cost and although this cost, also represents an investment, the life of the facilities estimated at 25 years, so it takes at least 10 or 15 years to recover the Initial price This depends on the area in which the installation was made, of course.
- The energy and radiation produced varies throughout the seasons.Generation of solar panels depends on the ambient temperature and the incident solar radiation. Less hours of light generates less solar panels, so at certain times of the year, it will be necessary to complete the production of energy with other fuels.
- Aesthetically, solar panels are not the best ally of a building.
- In the case of the use of photovoltaic solar panels, the price of the kWh generated is higher than through other technologies.
- The areas of greatest solar panels radiation are desert places, far from the consumption areas.
- In some cases, their installation is not allowed in protected buildings, such as Cultural Interest Assets (BIC).
- At the end of its useful life, the solar panels manufactured with materials that must be treated as hazardous waste.
As you see, usually the advantages of solar panels stand out and have more weight than the disadvantages, however, by after the logic of supply and demand, over time it is possible that their prices are more accessible and there are more options able Acquire a system that will undoubtedly add significant value to your estate.
