Solar Panel Design
Learning more about the specifics of a solar panel design will help you to better understand how solar-powered systems work. The advice that you will find in this article may put you a step closer to equipping your own home with a source of free renewable energy.
Solar panels are just one of the photovoltaic system's elements. However, they are definitely the major front-line component of the whole system.
Solar cells are wafer-thin slices of a semiconductor (e.g., silicon), with one side saturated with phosphorous (creates a positively charged surface) and the other side saturated with boron (creates a negatively charged surface). When these sides are combined, the space in between them forms an electric field. The most common semiconductors used in solar cells are silicon, copper indium diselenide, cadmium telluride, and gallium arsenide. Silicon is the first semiconductor that was ever used in the solar panel design, and it is still the most common material used in solar-powered systems.
The process of turning sunlight into normal power is as follows: the sunlight gets absorbed by the semi conducting material, the absorbed light reaches the electric field, the light transforms into energy, and electric is produced. Thus, the generated energy is converted into the electric current. The positive cell surface has an aluminized conductive coating placed on it, which allows for the electric current to pass further. The direct current is channeled to an inverter, which in its turn converts it into alternating current that is suitable for home use, battery storage, or electricity sent to the city grid.
The main parts of this system are: the solar panel (absorbs the sunlight), the charge controller (controls the charging of the battery), the power inverter (converts the power to 120 volt AC in order to run appliances), the batteries (store the excess electric), and an AC generator (for backup power). The other components include wires (to connect all the components into a system) and meters (to track the performance and the usage of the system).
The solar panel design involves connecting solar cells of varying sizes and shapes. The cells are assembled into panels, and the panels form arrays that consolidate power production. Solar units use specific materials (a special antireflective coating), which allow for the efficient absorption of sunlight. The chemically etched cell surface allows for the absorption of any reflected light, thus increasing the unit's efficiency. All units have different current output levels.
Solar energy can provide you with all of your electrical needs, as well as provide you with a power back-up, or supplement your electrical grid connection. These systems are perfect for remote localities where electricity is unavailable or unduly costly to connect to.
Solar systems produce free electric from sunlight, which may lead to complete energy independence for any household. Using solar power will lower your energy costs, help to decrease the global use of oil, decrease pollution, and combat global warming.
Learning more about the specifics of a solar panel design will help
you to build and install your own energy-generating system, which would
fit your home and your needs.
