Solar panels for RVs have become increasingly popular because they allow their owners to generate their own energy. When converting the house trailers into self-sufficient and self-sustainable vehicles, the installation of solar electric systems represents a great economic advantage since it reduces the expenditure on electricity and resources. In addition, it allows the traveler to move more comfortably by not needing to be connected constantly to a conventional electricity grid system.
At first, acquiring solar panels can be expensive; however, with the energy savings it represents, the investment can be recovered in a short period of time since the main purpose of the ecological technology is, mainly, the use of natural resources and the reuse of them, which leaves us a considerable reduction in terms of usage of expensive fuels and generation devices that must be replaced frequently.
There are many factors to consider when acquiring solar panels, among them, is to determine what type of system is better for our artifact. In the case of solar self-generation produced by panels, we have two types; the photovoltaic one and the thermal one. Photovoltaic solar panels work through the generation of chemical reactions and thermal panels function by means of reactions through the heating of water to create energy.
Photovoltaic solar energy is based on gaining power by the incidence of the sun’s rays on the panels’ surface, which generates a chemical reaction that consists of obtaining energy from the light, sending it to the electrons causing them to separate of neutrons and protons, and, then it is released in the form of electricity. This type of systems works better the more exposure they have to the sun, that is to say, they must be placed directly in front of the sun to get as much light as possible, and therefore produce more electrical charge.
The main components of these devices are photovoltaic cells, however, several types can be found within this category. Among them are the crystallines; monocrystalline, polycrystalline and amorphous. The monocrystalline are composed of sections of a single silicon crystal, polycrystalline are created from a set of crystallized particles and amorphous ones have silicon particles that are not crystallized. There are also solar panels made of gallium arsenide, cadmium telluride, indian copper diselenide or tandem diselenide.
On the other hand, we have thermal solar panels; its method of operation is much simpler because these devices, on the other hand and as their name implies, work by generating energy through the heat obtained from the sun’s rays. Inside the solar panels, pipes that allow the circulation of water are installed, this water is heated with the warmth absorbed by the solar panels and releases energy that is, then, converted into electricity. This type of system can be manufactured by hand, which makes it cheaper than the photovoltaic one. In this case, the types of thermal panels vary according to the degree of heat that they can reach, so they are divided into those of low temperature, medium temperature and high temperature.
For these reasons, to choose which type of solar panel is the best for us, we must consider factors such as the investment we have at hand, the electric charge we need to generate, and even the climate of the area in which it will be installed.
