A green future with solar panels

Today more and more households are in favor of the use of this energy source. Its use is very much in demand by the state and institutions in favor of ecology in several countries.

In fact, solar panels have several advantages for the economy and the environment.

Before any study on the effectiveness and benefits of using this source of energy with solar panels, it is necessary to have some understanding lexicons commonly used in the field.

Lexicons and different applications of solar energy

Solar Oven

Also known as the “solar cooker” , the solar oven is a cooking appliance that helps focus the energy of the sun to generate high temperature can be used to cook food or heating.

Solar thermal panel

The thermal solar panel is a device for recovering energy from sunlight and converts it into heat.

This heat can be used to produce hot water. This system is already well known but its use is widespread in France. It is present in more than 100,000 homes in the French territory for domestic water heating.

Photovoltaic module

The photovoltaic module is a device for converting solar energy into electricity.

This is a solar panel rectangular, rigid, and formed of an assembly of silicon photovoltaic cells.

The lifetime of a photovoltaic module is very long therefore its use is economical.

Several manufacturers, down 20% maximum power is expected on 20 or 25 years (estimated life).

Already in 2009, in France, photovoltaic systems allowed to produce more than 190 GWh, an amount equal to the electricity consumption of 85,000 people.

Solar power plants: for the production of electricity

A green future with solar panels

There are two types of solar power:

  • The thermodynamic solar plants
  • And solar photovoltaic

Generally, solar power plants are located in an area exposed to plenty of sunshine throughout much of the year, a flat area with a large open space in the presence of an electricity grid nearby.

The thermodynamic solar plants

The thermodynamic solar plants concentrate solar radiation through parables and mirrors then convert them into heat at very high temperatures.

This system can generate water vapor.

The thermodynamic cycle product is then able to drive turbines in relation to an engine for electricity generation.

The solar photovoltaic

The solar power plants are composed of a set of photovoltaic solar module systems.

They are one of the best ways for the industrial production of electricity using the sun’s energy.

A power function of the surface of the modules are obtained photovoltaic solar plant.

They have some advantages but also disadvantages to consider before opting for the establishment of a solar photovoltaic plant.


  • High reliability and no moving parts
  • Silent System
  • Low operating cost that is to say that maintenance is reduced

A green future with solar panels


  • Power generation is possible only on the day
  • The manufacturing cost is high
  • The yield is low

In 2011, the production of solar photovoltaic represented France in 2300 GWh. It should also be noted that the photovoltaic park has greatly increased with a figure of 185 MW connected in 2009 and 815 MW in 2012.

Solar panels and sustainable development

The use of solar panels offers considerable advantages from an economic point of view but also from an ecological point of view.

Environmental Benefits

The solar panels are beneficial to the environment because they are a source of clean energy .

They do not generate greenhouse gases or radioactive waste.

Unlike traditional energy sources such as coal and oil that have quantity limits that is to say, which can be depleted over the years, these traditional energy sources called fossil fuels that have effects pollutants, solar energy is inexhaustible.

The materials that make up the solar panels are recyclable, which is yet another advantage.

Considering the advantages of solar energy, the state, in many countries, helps promote the choice of renewable energy sources, including solar energy.

This promotion is often accompanied by public subsidies to guide, inform the public, consumers in the choice of renewable energy for sustainable development.

As part of state subsidies, it should be noted that a refund up to 60% of the installation cost is possible in case of a residential installation.

Economic and technical advantages

Aside from its benefits ecologically, solar panels have the economic and technical advantages.

For the consumer

First, we should note the possibility of a reduced rate of VAT (10% in 2014) with very good profitability.

Consumers can now make a lot of money by choosing this solution.

The presence of a photovoltaic installation in a house increases the value thereof.

The solar panels require very little maintenance once the installation is complete and have no form of noise for the use and the neighborhood.

For 25 years, a solar panel can produce an average of 2250 kWh and 3000 kWh of electricity.

Thus, the solar panels are an excellent investment for consumers.

For the supplier

For the supplier, opt for green solutions can make a difference with competitors in an open energy market to competition.

Indeed, the state organizations, governments of all countries, the EU clearly expressed their goals for sustainable development.

The promotion of renewable energy sources is a solution for a better future of the world as it will decrease the ecological disaster already and still accentuate today.

Energy dependencies for traditional sources may decrease as the population, consumers recognize the benefits of the use of energy sources for sustainable development as solar energy.

We must consider that the advanced technologies, research has to exploit a better way other renewable energy sources:

  • Geothermal energy
  • Wind energy
  • Energy hydraulic
  • Energy biomass including biofuels …
