PRICE OF PURCHASE OF SOLAR PANELS OF QUICK ESTIMATION
What is a solar panel?
In general, a solar panel is defined as a device to capture solar radiation and transform it into electric current. It consists of many solar cells . These are the last ones that ensure the conversion of the solar ray into electricity . Each cell has a thin plate with negative and positive charge. The transformation of light into electricity depends largely on the type of silicon. Used in the manufacture of solar cells. The solar panel can be mounted on a fixed support such as the ceiling or installed directly on the floor. For the sun’s rays to be well received, it must be inclined 30 ° to the horizontal axis. In this way, the production of electric current will be optimal.
Two types of solar panels are now commercially available:
- the solar thermal
- photovoltaic solar panel
This type of solar panel becomes directly the light of the sun heat . It is often used for domestic hot water production. For this, a transparent glass plate captures the sun’s rays. Under this glass, the metal plate, covered with a layer of chrome, will absorb the light rays. These will be converted into heat by the mechanism of heat transfer by radiation . The absorber, once heated, diffuses the infrared, which will then be blocked between the glass and the metal plates. This is called the greenhouse effect.
The air between these plates, when heated, optimizes the performance of the device. The thermal energy will be sent to a heat transfer liquid that will be heated to be sent to a hot water tank. Routing can be done by gravity or by means of a pump. In an accumulator, the refrigerant flows through a circuit and returns its heat to the sanitary water.
The photovoltaic solar panel
This type of solar panel is a bit more complex, especially at the installation level. It converts directly sunlight into electricity . The photovoltaic solar panel is composed of numerous silicon-based photovoltaic cells , each of which delivers a voltage of 0.5 to 0.6 volts. . The assembly was designed to obtain photovoltaic modules capable of supplying a normal voltage of 12 volts. As soon as the light is captured, its energy causes a break between the electron and the silicon atom, thus modifying the electrical charges. Three types of photovoltaic cells, whose power varies according to the quality of silicon, are available in the market: monocrystalline cells (appreciated for their excellent performance), amorphous cells and polycrystalline cells .
The price criteria of a solar panel.
Energy is one of the criteria that define the cost of a solar panel. The most requested installation is between 1.5 and 3 kW and is equivalent to 15 and 30 m² of panels. The price of a solar panel also depends on the area to be covered and the number of people in the house. The brand, type and performance of the device are factors that will vary the price.
Cost of equipment purchase.
The cost of the thermal panels varies according to the technology used and the surface of the sensors. For thermal panels with flat collectors, it costs about 450 euros . The thermal panels equipped with 15 vacuum tubes are sold for about 550 euros . With a budget of 1,500 euros , it is possible to purchase thermal panels with high-end sensors.
The cost of a photovoltaic solar panel ranges between 900 and 4500 euros per kilowatt maximum. For a power of 185 to 280 Wc , the price ranges between 1,500 and 4,000 euros and between 1800 and 4500 euros for a power between 225 and 305 Wc .
The cost of installing a solar thermal panel is between 4,000 and 10,000 euros . This price depends on the design to be implemented for the installation of thermal sensors, the type of system adopted and the use of thermal panels.
Depending on the surface of the panels, the installation surface and the chosen professional, the installation price of a photovoltaic solar panel can cost between 10,000 and 25,000 euros .
Some tips to choose a solar panel.
If you want to operate your electrical equipment with solar energy, photovoltaic panels are ideal. These will also allow you to have energy independence. If you want to install a solar panel only for the production of domestic hot water, you can resort to thermal sensors. These also provide additional heating and swimming pool.
How to finance the installation of solar panels?
The initial investment required to install solar panels is certainly high for a medium-sized house that requires, for example, 20 m² of solar panels.
But there are several types of subsidies, such as Anah’s help, the tax credit or local subsidies, which will significantly reduce the price of their solar panels.
Also know that with the installation of solar panels for a value of 8000 euros for an area of 20 m², in a medium-sized house located on the island of France, you will save approximately 20,000 euros after 25 years of age.

What are the different types of solar panels?
A solar panel is a large, square or rectangular plate, equipped with a frame and an insulator that absorbs solar radiation to transform them into thermal energy and / or electricity.
There are two types of solar panels or solar collectors on the market. There is a photovoltaic solar collector and a solar thermal collector. The first produces electricity and the second produces hot water. Both are perfect complements of conventional electricity (fuel, nuclear), whose price has increased in recent years.
Even if the price of the panels is quite expensive, its production remains controllable. In fact, the amount of energy produced varies according to the dimensions of the sensor used and, therefore, also the price. Each household can find what best suits their needs within the limits of their financial capacity.
Average price of solar panels
The price to pay for a solar panel depends on its size and the category to which it belongs: thermal or photovoltaic. It also varies according to the power of the sensor and the quality of the place where it will be installed. The average price of a photovoltaic installation is 13,500 euros on average, including supplies and installation (including connection), for a power of 3300 kWh / year . These are some prices per m2 of each solar panel model, with the exception of the installation, to obtain a more precise idea:
|Type of solar panel||Price per m2|
|Photovoltaic solar panel||200 to 300 euros / m2|
|Solar thermal panel||€ 200 to € 400 / m2 (glass sensor)
€ 600 minimum / m2 ( tube collector )
|Photovoltaic tiles||400 to 1,000 euros / m2|
