Module factory
PV modules, known as solar panels, are composed of a set of cells (silicon cells) whose function is to produce electricity from solar radiation. Photovoltaic panels are basically divided into three types: polycrystalline, mono-crystalline and amorphous, each of them has different efficiencies because each material has a different driver character. It can be stated that the effectiveness is higher the more crystal possesses, the panels or modules are delivered by a photoelectric effect than silicon cells interact with solar radiation freeing electrons from the silicon atoms.
The latter are connected to electrical conductors and thus starts the electric current in polycrystalline PV modules the main component is silicon combined with boron. Many wonder if making a photovoltaic module is a complex task, the answer is "no", but basic knowledge needed to obtain the desired results, a single solar cell has a voltage close to 0.5 V, therefore if connecting them in series (positive to negative), we get much higher voltages.
The solar module manufacturers now say that panels are made of various sizes for different purposes, some people opt for power generating equipment to heat the water tanks of the houses, others to heat swimming pools, and another group of people to generate heat.
We have three basic types of PV modules: the low voltage or low power, small and large, the former are made by connecting between 3 and 12 small pieces of amorphous silicon thus obtaining voltages between 1.5 and 6 V, used in calculators, watches, cameras and automatic lights. The major modules produce between 10 and 60 watts, are constructed by connecting from 10 to 36 cells in series of the same size we can see in the small pumpers or household power equipment, communications and energy sources in remote areas. Finally we have the small photovoltaic modules, they generate between 1 and 10 watts and are made from pieces of monocrystalline or polycrystalline cells of 100 cm squares that are assembled in series we can find in radios, toys and electric fences.
Constitution of the structure and uses
Sometimes a photovoltaic solar panel is not sufficient to obtain the necessary energy, so supplements are needed, when it comes to more than one panel modules are referring to, they are composed of: more than two photovoltaic panels, control panel which regulates the energy of the panels, a storage system, an inverter for converting direct current into alternating current and a cover.
The modules can be operated in series or in parallel, which are manufactured today are designed to minimize energy losses, these sets of modules used in the construction of buildings to provide electrical power, it is estimated that when the price of solar cells decreases, the housing with integrated solar cells will be required, at least in Europe.
Solar modules have the most sophisticated trackers, these structures are responsible for guiding the team to capture all the sun no matter where you are the sun and are used mainly in large hectares and in regions where solar radiation is minimal. Batteries for photovoltaic panels are responsible for performing the tasks of storage, what are they?, Simply to take advantage of energy captured during the day in periods when the sun does not do this. Each battery is 2V, should have panels connected in series, then the batteries remain connected in the same way to provide the necessary energy level. Batteries are solar panels that have made this phenomenon in a viable project, because by using it, we can use the energy stored in any time of day without relying on the presence of sunlight.
