At a time when many countries are engaged in an energy transition process, solar energy is emerging as an interesting alternative for the future. What uses is solar energy reserved for? What are the main advantages of this type of energy?
Focus on the main information to remember.
WHAT IS SOLAR ENERGY FOR?
There are several types of solar energy.
• Solar thermal energy Solar thermal
energy is used to heat a fluid which in turn will heat domestic hot water and / or the fluid in a central heating circuit.
• Photovoltaic solar energy Photovoltaic
solar energy makes it possible to produce electricity. The latter can be used by households as well as in industrial activities. Lighting, various appliances, electric heating, etc. : Electricity produced by photovoltaic solar energy can be used in many ways.
HOW CAN WE USE SOLAR ENERGY?
Solar energy can be exploited by using different types of devices:
• Photovoltaic solar panels. These devices capture energy from the sun’s rays through modules and convert them into electricity.
• Thermal solar panels. They allow water to be heated using solar energy.
• Hybrid solar panels, which produce thermal and electrical energy from the sun’s rays.
• Thermodynamic solar systems. These devices harness the sun’s radiation through thousands of mirrors. They reflect sunlight to receivers which are steam generators. Pressurized, this steam will run an alternator which will produce electricity.
WHAT ARE THE DIFFERENCES BETWEEN AEROVOLTAICS AND PHOTOVOLTAICS?
Photovoltaics and aerovoltaics are two systems that generate electricity from the inexhaustible natural source of the sun. In addition to this similarity, aerovoltaics and photovoltaics are different in many ways. Total.fr enlightens you and helps you differentiate between these two installations to make the right choice.
AEROVOLTAIC: 4 TIMES MORE ENERGY FOR A SINGLE INSTALLATION
Unlike photovoltaics which uses sunlight and converts it into electricity without taking advantage of the heat it produces, aerovoltaics take advantage of this heat and diffuses it into the home using a ventilation module coupled to a CMV. This heat makes it possible to produce 4 times more energy. Indeed, when a photovoltaic panel uses 20% of solar energy, the aerovoltaic panel uses up to 80% of the solar energy captured.
A MULTIFUNCTION INSTALLATION FOR AEROVOLTAICS
Another difference between aerovoltaics and photovoltaics : the use made of the energy produced. On the one hand, photovoltaics only produce electricity. On the other hand, the aerovoltaic adds 3 other functions to its installation:
The various functions performed by an aerovoltaic installation confer a certain energy autonomy to the occupants of the equipped accommodation. Much greater autonomy than that provided by a photovoltaic installation.
PHOTOVOLTAIC AND AEROVOLTAIC: A SIGNIFICANT PRICE DIFFERENCE
While aerovoltaic panels have many advantages over photovoltaic panels, the latter are half the cost to install. For several years, photovoltaics have been able to gain a foothold in the renewable energy market and its initially high cost has been able to drop thanks to an equalization of the prices of materials and installation. Obviously, the aerovoltaic is promised an equivalent decrease over the years but in the meantime, the photovoltaic remains more interesting to the acquisition and the installation.
Good to know
If the aerovoltaic represents a significant initial investment, it makes it possible to achieve savings of up to 50% on energy bills quickly thanks to its multiple functions and the autonomy it provides. In addition, it produces 10% more electricity compared to photovoltaics.
DIFFERENT FINANCIAL AID DEPENDING ON THE FACILITIES
The amount of an aerovoltaic installation can be reduced thanks to financial aids, much more numerous than those allocated to a photovoltaic installation. In fact, the aerovoltaic benefits:
the tax credit for the energy transition: ie 30% of the value of the equipment excluding labor, up to € 1,200;
5.5% VAT: on condition that the installation is intended for a dwelling;
zero rate eco-loan of up to € 30,000.
In addition to these three financial aids, the aerovoltaic benefits from an investment bonus, in the same way as the photovoltaic. This premium varies according to the installed capacity.
