What type of solar panel to choose?

 



[Sunlife]There are 3 types of solar panels that are distinguished by their characteristics and the type of the energy they produce.

Among these, you will find the thermal panel, the photovoltaic panel, and the hybrid model.

Solar thermal panel

The solar thermal panel is a device that converts solar energy into heat energy.

It is used to have domestic hot water, but also to supply the heating system.

Note that unlike the photovoltaic panel, it does not provide electricity.

Initially, the panel will capture and absorb solar radiation and heat to heat a coolant.

Then, this liquid, glycol water most of the time, will circulate and heat the water in a storage tank which is generally equipped with a back-up.

Regarding its installation, the solar thermal panel must be oriented South and have an inclination of 45 °.

Compliant with RT2012, the thermal panel is eligible for financial aid.

Aerovoltaic Solar Panel

It stands out for the fact that its lower layer uses air circulation to recover solar heat.

The hot air thus recovered will be diffused in the accommodation or used in a thermodynamic water heater.

The main disadvantage of this device is that it is only really effective during hot seasons.

Rather complex, its installation involves the integration of the device into the roof and the installation of an air delivery system.

To ensure its effectiveness, the aerovoltaic panel must be oriented towards the South with a slope of 30 °.

Of course, care must be taken to ensure that the entire surface of the panel is clear.

Areas shaded by a tree or a building should, therefore, be avoided.

Like the thermal panel, the aerovoltaic hybrid panel is eligible for the 30% tax credit on equipment with a ceiling of € 200 / m² for a total area of ​​20 m².[Solar energy in Pakistan]

Being the most expensive type of panel, its price varies on average between 10,000 and 15,000 € for a power of 3 kWp.

Hybrid Solar Panel



As its name suggests, it is a mixed solar collector that combines the technologies of the thermal panel and the photovoltaic panel.

These new types of solar panels capture both solar radiation and heat. 

The electricity obtained can power your various devices and lights.

For its part, its heat exchanger ensures the production of hot water for the entire home.

The hybrid solar panel is, therefore, an effective solution to achieve energy independence.

The fluid it contains will also cool the panel, which will increase its efficiency.

To guarantee its performance, the hybrid solar panel must be oriented south with a slope of 30 °.

To install it, it is necessary to fix the rails on the roof before placing the panel there and connecting it with the fluid pipes.

The hybrid panel is the most expensive with a price which generally varies between 13,000 and 20,000 € for a power of 3 kWp.

The installation of this solar panel is eligible for the 30% tax credit but with a ceiling of 400 € / m² for a maximum surface area of ​​10 m².

Photovoltaic Solar Panel

The photovoltaic solar panel is the solar collector that converts the sun’s rays into electricity.

Thanks to its cell technologies, the PV panel captures the photons contained in solar radiation to produce current. [Solar Panel in Pakistan]

It is formed by a semiconductor material with photovoltaic cells in PN junction: a positive layer and another negative.

When the photon of the solar ray snatches an electron from the atom, a positive charge (a hole) will form to ultimately produce a direct current.

It is direct current which will be transformed into alternating current by the inverter which is, of course, part of the installation.

This alternating current will then be used by your domestic installation.

The photovoltaic panel is the type of panel most used today thanks to its efficiency and its price much more accessible than that of the hybrid panel.

It is also very easy to install. [Solar panel in Lahore]

Indeed, many homeowners install their photovoltaic panels themselves.

For optimum efficiency, a slope of between 30 and 35 ° should be observed, ideally on a south-facing roof.

The installation of a photovoltaic panel costs on average between 2000 and 2800 € / kWp.

This price must include administrative procedures, the cost of equipment (panels and inverters), connection, and labor.
