Photovoltaic solar panels are devices made of glass and aluminum that transform light energy from sunlight into electrical energy. The electrical energy derived from the sun can successfully replace the classic electricity distribution system.
Thus, the sun can become the main source of energy for a house on whose roof solar panels are mounted, and this makes the monthly bill decrease considerably.
Practically, the energy provided by the sun can be used without limits, it is free and does not pollute, and once these panels are installed, you will no longer have to worry about power outages. The voltage of the current produced by photovoltaic panels does not vary, as in the case of the classic distribution system, so there is no risk that household appliances will be affected.
The investment can be quite large, but it has been proven that a house with mounted solar panels consumes 9 times less energy than a classic dwelling. For days when the sun is not shining brightly, a battery is needed to store the energy.
Solar thermal panels
Unlike photovoltaic solar panels, a solar thermal panel is an installation that captures the solar energy contained in sunlight and transforms it into thermal energy. Using solar energy with these panels is the most ecological method of heating domestic water, as well as heating homes.
Depending on how the sun's rays are transformed into heat, the panels come in two types: flat panels or evacuated tubes.
