The hybrid solar panels are panels combining the functions photovoltaic and thermal. They simultaneously serve for the production of electricity and heating. The hybrid system is can be appeared but it is recently increasingly prevalent. An early success due to the opportunities and benefits it offers.

Birth

The hybrid solar panels owe their birth to the concerns of manufacturers to find a solution against the temperature rises in photovoltaic cells. Increasing the heat inside the module is a major cause of yield loss of photovoltaic solar panels. Hence it need of a heat dissipation system.

Liquid cooling has recovered heat from solar cells and use it to heat the water.

Operation

Hybrid solar panels combine photovoltaic sensors and thermal sensors in one module. They are called PV / T collectors.

Photovoltaic panels are placed on the front layer of the module. They are connected, as in the case of a photovoltaic solar panel normal, to a system for transporting electric current in the room. Thermal sensors are located in sub-layer for sensing the heat generated by the operation of photovoltaic cells.

As in a thermal solar panel, a heat transfer fluid flows through the thermal sensors in tubes for recovering heat and conveying it to a buffer tank.

Note: The term hybrid is also used to designate mounted solar panels with a wind turbine, or portable solar kits combined with small wind turbines, usable in outdoor activities, the camper or for boats.

Benefits

The most obvious advantage is the stabilization of the temperature in the photovoltaic module. This stabilization allows a higher efficiency of electricity production. An efficiency of 40% (compared to conventional panels) is advanced by distributors.

This system enables a space saving important for those who wish to use photovoltaic panels and solar thermal panels. There is no need to develop an area of major facility to accommodate two different modules.

 

Disadvantages

The desire to stabilize the temperature of the photovoltaic module causes a need for heat dissipation constant. The heating water can not thus be sufficient. A heating system of the house is thus most recommended. For homes with swimming pools, excess heat can be used to heat them.

The photovoltaic efficiency is more beneficial than the hybrid system thermal efficiency. Systematic temperature stabilization may cause inefficiency of the solar thermal production.

Price of a hybrid solar panel

The price of equipment: is still a new technology, the price of solar panels hybrid is higher than the price of conventional solar panels.

The cost of the installation: compared to photovoltaic and thermal separate systems, the hybrid system allows installation cost unified. So a single study for all, instead of 2 separate. This equates to a reduction of the exposure time, work time and cost of travel for your installer.
