During recent years the issue of climate changes has gained a large audience and importance in all countries of the world.
This is very simple to understand, everywhere we see the consequences of that changes: Floods, unusual temperatures in many countries, droughts, etc.
Is not unknown to anyone the causes of these phenomena: The indiscriminate use of highly polluting fossil fuels such as petrol, gas, diesel, etc.
During the last years, have been developing alternatives of clean and renewable energy sources, the most popular: Solar energy and wind energy.
The technology has advanced so much, and today exist in the market many options under the scheme of "do it yourself" guides that offer teach you how to build a solar panel or wind turbine for your home.
Of course, if you are not the kind of person how likes the "Do It Yourself" guides, you always can hire some technician guy who will do the "dirty" work for you.
Today, is entirely up to us, no more cost or technology excuses!
We will review the 4 main components of a photovoltaic system or solar panel system:
1.-Solar cells.-
Are a component of the photovoltaic system, are extremely fragile, not electrically isolated and have no mechanical support, so, once made, should be assembled in the proper way to form a single structure rigid and hermetic: Photovoltaic panel.
Solar cells should be equal. Are electrically connected to each other in series and / or parallel, so that the voltage and current supplied by the panel is increased to fit the desired value.
2.-Photovoltaic panel:
Modules or panels are the main elements of any PV System (Photovoltaic system for short) and its function is to capture the incident solar energy to generate electricity.
Most of the solar panels are constructed first by associating cells in series to achieve the desired voltage level and then combining in parallel a number of associations of cell lines to achieve the desired current level.
3.-Batteries
Batteries or accumulators are used to accumulate the energy that the panels generate daily and to be used in time where energy consumption is higher than the generated, as at night.
Another important function of the batteries is to provide a current higher than the photovoltaic device can deliver. This is the case of an engine which in the boot time can use a current of 4-6 times its rated current for a few seconds.
Moreover, the battery provides a stable and constant voltage independent of the incident light conditions, which may be the most suitable for the operation of electrical appliances.
4.-Charge controllers:
Bearing in mind that solar energy is variable and seasonal, it is extremely important to have a device to control the relationship established by battery and the generator system (PV Panel).
Suppose that consumption is equal for all days of the year. To calculate the required number of solar modules, must be based on winter radiation to ensure the proper functioning of the system, because that is the worst time of solar radiation of the year.
But when summer arrives, the value of radiation can be duplicated, so that production will be twice that calculated for the winter, while consumption is the same. If we do not have a regulatory system, there would be an excess supply that would be able to boil the electrolyte with the consequent loss of water and deterioration of the group accumulator (battery), because the charge is not regulated.
Regulator or charge controller is the device that manages the direct consumption of the plates of the batteries, and avoids overloads or deep discharge, thus extending its life. It also generates alarms based on the state of the charge.
Regulators are installed between the generator and battery system, taking from these last one the energy it needs for its operation.
If you are interested in build your own solar panel for your home or your wind turbine for less than $200 each, and therefore save money (reducing or cutting at all your electrical bills) and help to improve the environment, if so, visit my site and find how:
