Solar panels: a good investment?

According to RTE, the French photovoltaic park produced 8.3 TWh in 2016, i.e. 1.6% of national electricity production for the year. Solar electricity could represent between 20 and 25% of global electricity production by 2050 according to the International Energy Agency. It is therefore a sector of the future in which you would do better to invest by installing solar panels…

Solar energy: undeniable advantages

In 2015, photovoltaics and solar thermal represented respectively 2.7 and 0.4% of the primary production of renewable energies in France, even though solar energy has several undeniable advantages for the energy transition, all sectors combined.

Renewable energy, freely available, and in colossal quantities (even inexhaustible on a human scale), solar energy has no or very little impact on the environment, over its entire life cycle. Pollution is reduced and controlled during the manufacturing phase, non-existent during the operating phase, and all the components can be recycled.

The facilities and technologies are simple, mature, innovative and guarantee of safety: they present a low risk of accident. They are also modular (size, environment), which makes electricity and solar heat suitable for the decentralized production of all-terrain energy, and this in the long term, since the installations have a lifespan of 20 to more than 30 years. .

A drop in production costs that continues

Solar energy confirms its competitive energy status, with an accentuated advantage in the future thanks to lower investment costs.

  • with an estimated drop in the LCOE of 25 to -30% for photovoltaics between 2015 and 2023 depending on the segments considered. The production cost of large solar power plants could therefore drop from €68/MWh in 2015 to €50/MWh by 2025.
  • with a drop in the LCOE which could exceed 30% for solar thermal between 2015 and 2023.

Financial aid for individuals

Tax credit for energy transition, zero-rate eco-loan, Anah’s “Living better” program, energy savings certificates, reduced-rate VAT, local aid, etc. as part of a housing renovation project, individuals can claim financial aid. Cumulation between grants is sometimes possible.

Financial support for solar thermal

For individuals, a solar thermal installation, such as an individual solar water heater, is mainly supported by the energy transition tax credit. This was simplified on January 1, 2015, with the implementation of a single rate of 30%, without means test and without a bouquet of works.

Local aid

To develop solar energy, many regional councils, but also general councils, municipalities, ANAH, etc., offer assistance to individuals complementary to the tax credit.

ADEME and the Regions financially support collective solar hot water operations, in new or existing buildings, at the various stages of the project (study, investment).

Call an RGE installer!

Are you embarking on a construction or renovation project? Be sure to contact an RGE company to take care of your solar thermal or photovoltaic installation.

What is an RGE installer?

The mention the reference Recognized Guarantor of the Environment (Where EGR), certifies the quality of energy renovations by committing professionals to the efficiency of their service. This statement has been put in place by the public authorities to provide you with transparency and allows you to carry out your energy renovation project in all serenity.

In order to obtain this certification, companies must meet general (insurance, material, financial and human resources) and technical (training, references, audits) criteria, while being objective and transparent.

Why find an RGE installer?

By resorting to a RGE certified company, you ensure the quality of the installation. Indeed, if you do not call on a craftsman EGRthe consequences can be considerable:

• Work that does not comply with regulations (malfunction of the installed system)

• Not benefiting from financial help public authorities (MaPrimeRénov’, CEE, Eco-PTZ, reduced rate VAT, etc.)

Doing appeal to an RGE companyyou are sure that the company:

  • is assured
  • is reliable
  • is competent
  • accompanies you throughout your project
  • is recognized by the public authorities
  • allows you to have a reliable installation, quickly making your investment profitable

In summary

If the North is a bit interesting region than the others to install solar panels, it can still be worth it. Do not hesitate to ask the experts!

Solar panels go mainstream

The accumulated delay in solar energy is due to a technical choice of the French State. The latter preferred to ensure the protection of the French market, compared to the European. In addition, the integration of panels in the roof, instead of tiles, was imposed. However, this does not allow optimal ventilation and sealing, which has created a lot of problems.

It was this flop that brought it all to a halt. The sector collapsed but has been on the move for 2 years. From now on, individuals and professionals have the right to self-consumption, which was not the case before. In short, you produced electricity, which was sold and which you had to buy back… Not very logical, nor incentive.

Profitability over the long term

As the solar sector becomes interesting again, it will be democratized. This responds in particular to the desire of citizens to consume the electricity they produce. And yes, the energy transition also goes through this (then it’s better for the wallet). Indeed, professionals in the field realize that what matters is profitability. If the ecological interest is present, it does not represent the main motivation for households.

If the solar panels do not allow to be independent, they can however mitigate the breakdowns of the electrical network. Moreover, with the rises in the price of energy, solar panels make it possible to ensure a certain energy independence. Installing panels can cost around €6,500, which is a significant investment. But we must see behind this fixed cost, the interest in the long term brought to individuals and professionals who make this choice.
