Solar energy: advantages and disadvantages

While the prices loaded by energy suppliers are increasing and ecological concerns are growing, individuals tend to contact photovoltaics as an alternative to the nuclear electricity distribution network for their diet. In a context in which the offers of solar panels are numerous and suppliers support in their direction, it can be useful to be based on an objective evaluation, in support of the data, before making its decision. To invest consciously, the sunny earth explains the advantages and disadvantages of solar energy in complete transparency.

Solar energy in the face of the ideas received

Stop the preconceived ideas and the deceived sales topics, the sloping solar land for you the advantages and disadvantages of solar energy in all objectivity.

Be independent of the distribution network

REAL. Solar panels allow you to produce electricity. Consuming this electricity for your energy needs, the network is not used.

And false! Unless you give up on your profitable solar installation, in no case the current technologies allow total autonomy. Therefore you are not independent of the 100 %network.

Advantages for everyone

REAL. In the south or north of France, photovoltaics allows you to produce electricity without sacrificing profitability. Only the performance level changes: the sunny the installation, the more you produce. In these conditions, your return on investments is all faster in the South.

It is expensive, but the investment is profitable e There are financial aid

REAL. Investing in photovoltaics requires a significant, profitable cost when the installation is implemented in the conditions that allow it.

Example in the figures:

• Count from € 16,000 to € 22,000 for an installed power of 9 kWc. This type of installation is profitable in 9 years in the north, 11 years in the south-east for a minimum duration guaranteed for 25 years.
• The 3kwc photovoltaic kit, offered at an attractive price, is profitable in over 20 years.

If the tax credit is no longer in force, the individual can always benefit, in conditions, from different devices: eco-loan to zero rate (all legal information, downloading form and conditions available on the service-service-service), local financial aid, prize for self-consistency.

The installations are unpleasant and maintenance efforts are regular

Fake. Particularly sensitive to aesthetics, the individual can integrate its discreetly-IDB solar panels and entirely black panels. Suppliers now offer advantageous solutions to benefit from sun energy without sacrificing the aesthetic of his home.

In terms of maintenance, efforts are limited to the extent that:

• East south, no risk of appearance of foam on the panels.
• Included at a minimum of 15 °, the installation is naturally clean by rainwater.

A bad ecological evaluation

Fake. Solar energy, in addition to constituting 100 %green electricity, today has a good ecological evaluation. Therefore, the production and recycling of photovoltaic panels are taken into consideration:

• To create a panel, it is necessary to dissolve the glass and the silicon: this procedure even requires energy. But an equivalent amount of green energy is produced in France by this same panel in just 1 year. In addition, manufacturers have the opportunity to use solar energy to make the panels, for an even better ecological evaluation!
• Mainly composed of glass, aluminum and silicon cells, the panel is almost entirely recyclable and infinitely.

In any case, the carbon imprint of solar energy production systems is at least 2 times better than the carbon imprint of the nuclear sector. The advantage of an equally less level of pollution …

An inexhaustible and free resource

REAL. Advantage for the planet and for the particular, solar energy is undoubtedly inexhaustible and will remain free. 2 reasons:

• The duration of the life of the amounts of the sun in billions of years.
• The sun does not belong to anyone!

The yield decreases over time

It is true, to a certain extent. Of course, the solar panel does not produce so much electricity the year of its installation and 30 years later. However, the loss of performance, provided that you purchase quality equipment, is relatively low – a 20 % loss after 32 years of use for the Tiso test center in Switzerland. The producers also guarantee the loss of return of less than 17 % after 25 years.

Evaluation of the advantages and disadvantages of solar energy

Invest in solar energy

Photovoltaic electricity to protect the planet by contributing to ecological effort is the certainty of benefiting from the advantages of solar energy without any inconvenience.

When the specific financial issues for the individual are taken into consideration, on the other hand, the corner is different and it is necessary to take into account the main disadvantage of solar energy: the cost represented by the initial investment. When the individual must resort to bank funding to buy and install his solar panels, it is important to keep in mind that the profitability of the project depends on 2 main criteria:

• The sun sun: the faster is the region, faster is profitability.
• The power of the installation regarding its price. Be careful not to succumb to an attractive offer, at risk of closing the possibility of any return on investments. On the contrary, too expensive solar installation is never profitable.
