The use of coal contributes to the formation of poisonous gases and environmental pollution, and that's why people are looking for an alternative sources of energy. In the face of the challenges of climate changing, we are faced with the need to look for alternative energy sources to reduce environmental pollution. One of them is the use of solar energy in the form of solar panels mounted on the roof. They can be used both for heating domestic water and supporting central heating, or can be used as a photovoltaic source of electric energy. From my post, you will learn how to use solar heat and solar panel to get cheap hot water for the own household.

Solar panels

Solar collectors are in the form of mirrors with very large surfaces or a structure consisting of vacuum glass tubes. Panels are mainly installed on the roofs of houses. They catch the rays of light, thus accumulating the energy needed for conversion into thermal energy.

Such a process of accumulating heat is possible thanks to the absorber placed behind the glass or in a glass tube. It absorbs energy from the sun and is connected to a system of copper pipes. The heating-up solar liquid, propylene glycol solution, flows through them, from which the heat is transferred to the utility water.

Benefits of solar thermal panel

The advantages of solar collectors cannot be overestimated because their installation allows, in a completely ecological manner, to obtain heat necessary to hot tap water and to support central heating. Another advantage of solar panel is that they are working without polluting the environment.

Their third advantage is energy efficiency. Solar thermal panel meet up to 70 percent of the annual demand for thermal energy, which is needed to heat domestic hot water, especially in the months from March to the end of October. In the summer, a properly selected solar panels set will cover up to 100 percent of the demand for domestic hot water.

Another advantage of solar collectors is the convenience of their use and trouble-free operation. Correctly mounted on the roof solar panel, will require maintenance around one time per one-two years. Solar panels are versatile devices that can be installed on the roofs of single-family and multifamily houses, as well. Installation of solar panels will increase the value of your house. Now, when you know more about solar panels, you can decide to use them or not. If you are house owner, it is worth to take positive decision and install solar panels or PV panels.
