Compared with a generator of electricity, there are rotating and require fuel to be able to generate electricity. His voice is loud. In addition the exhaust gas the resulting effect may give rise to GHG (green house gas) that influence could damage the ecosystem of our planet Earth.
Solar cell system used in the Earth's surface consists of a solar cell panel, circuit controller charging (charge controller), and aki (battery) 12 volt which is maintenance free. Panel solar cells are made up of several modules that solar cells are merged in connect series and parallel depending on the size and capacity as needed. Frequently used is the solar cell module 20 watt or 30 watts. Solar cell modules that generate electricity which is proportionate to the surface area of a panel that is exposed to the Sun.
Controller circuit in the battery charging system that is a series of solar cells electronic regulating the process of charging akinya. This controller can set voltage aki in voltage 12 volt hose plus minus 10 percent. When the voltage down to 10.8 volt, then the controller will fill the aki with solar panel as its resources. Of course the process of filling it would have happened if there are currently taking place on the sunlight. If drop in voltage that occurs at night, then the controller will disconnect the supply electrical energy. After the process of filling it lasted for several hours, the battery voltage is going up. When the voltage reaches 13.2 volts battery that, then the controller will stop the process of charging the battery. Charging controller circuit it is actually easy to be assembled on its own. But, it's usually set this controller is already available in a State so on the market. Indeed it's quite expensive price controller if purchased as a separate unit. Most solar cell systems were only sold in the form of a complete package that is ready to use. So, the solar cell system in the form of a complete package that's definitely less expensive compared to when you assemble yourself.
Usually it's put the solar panels with a static position facing the Sun. When the Earth's motion around the Sun. The orbits of the Earth are taken with the Sun being in elip one focal point. As the Sun moves to form an ever-changing, then with the position that the solar panels that will not be retrieved the static electricity that is optimal. In order to be absorbed to the maximum, then the Sun would have to be organised always falls perpendicular to the surface of the solar panels. So, to get an optimal electrical energy systems, solar cells, it remains to be equipped with a series of optional controllers to set the direction of the surface of the solar panels so that it always faces the Sun such that the rays fell almost perpendicular mahatari in the suryanya pane. Such a controller can be built, for example, by using a microcontroller 8031. This controller is not simple, because it consists of the hardware and the software. Normally, the solar cell system packages are complete, excluding the controller to move solar panels automatically so that the Sun's rays fall perpendicular. Therefore, this kind of controller is quite expensive.
