Solar energy, okay, but what are the real advantages of a solar panel? And the disadvantages that come with it? I answer you here.
Advantage Of A Solar Panel: Sorting Out The Real From The Fake
The solar panel is seen as a way to preserve the planet, save money and sometimes even act as a financial investment. Profitability of the solar installation, economy, and conservation are three different objectives. Today I suggest you lay it all down and look at the real pros and cons of solar panels.
We start right away with the ecological aspect. Ecology as an advantage of the solar panel?
We begin immediately with the incriminating aspects.
The solar panel is recyclable
Here we are faced with a new preconceived idea: the solar panel is not recyclable.
We are going to dissect together the main components of a panel. You will quickly see that here again the reality is not faithfully transcribed.
Here we go, a photovoltaic solar panel is composed of:
Silicon: up to 4 possible reuses
Glass: infinitely recyclable
Aluminum: almost infinitely recyclable
These three components represent 95% of the photovoltaic panel, a module is 94.7% recyclable. Suffice to say that with technical progress we will very quickly reach 100%. Recycling is a very important aspect but it also consumes energy, isn’t it? Do you see what I mean? We come to the energy consumed to manufacture a photovoltaic solar panel.
Solar Panel Is Environmentally Friendly
The various points that we have just seen ensure that photovoltaic energy is ecological energy. It is therefore not wrong to say that installing a photovoltaic system is a gesture for the planet.
In addition, a photovoltaic system can be combined with a heat pump, for example. What I mean by this is that photovoltaics can also produce heat. These are therefore energies that can be created without increasing our energy debt.
Once installed, your panels do not emit CO2 to convert the sun’s rays into electricity. Producing clean and sustainable energy is one thing, producing it over the long term is another.
The reliability of a solar panel
Solar energy has not always had a radiant image in the hearts of the people. Now we can proudly say that photovoltaic installations are reliable and profitable.
Disadvantages of the solar panel: Energy cost of its design
The energy cost of designing a photovoltaic panel is very high. This statement is true. When you make a solar module, you have to melt the glass and the silicon.
A small aside, silicon is the chemical element most present in the earth’s layer after oxygen.
Melting these two materials requires a lot of energy. After its manufacture, it must be transported to its place of destination (very often the panels come from China). We must therefore take their carbon footprint into account.
On the other hand, what is not said enough is that the photovoltaic panel creates the equivalent of the energy is required for its production. It is estimated that in the space of 2 years its energy debt is completely repaid.
In terms of ecology, we have seen that the panels were not such bad students. It all depends on your need for green electricity, your production capacity, and your mode of consumption.
If you choose to install one at home, tell yourself that your consumption habits need to be reviewed. It will be necessary to make everything work in the middle of the day and no longer in off-peak hours.
From a reliability point of view, we have seen that the lifespan of an installation is very long. You will surely have an inverter to change after the first 10 years but apart from that the rest of the system is very robust.
We can therefore say that yes, solar panels can save the planet and save money.
