You have a degree in engineering. isn't that taken for granted?For everyone, including non-Scientists, who provide information on the use of solar panels for families, and information on how to build their own cheap solar systems.Do you know that the level of sunlight that falls on the surface of the Earth is enough to meet our energy needs --Nearly 6,000 times higher than the average human consumption of electricity.Among renewable sources, solar power has the highest power density.People are starting to recognize this: Photovoltaic (technology that converts sunlight into electricity) production doubles every two years, growing by an average of 48% per year since 2002, making it the fastest in the worldThe development of energy application science.How does the residential solar system work?Solar panels are placed in your yard or on the roof, where they can get the maximum amount of sun during the day by adjusting the angle of the panel facing the sun.The solar panels consist of many interconnected photovoltaic cells that convert sunlight directly into electricity.If you have enough solar panels, you can meet all the electricity needs in your home.The electricity of the solar panel flows in the form of DC (DC) at low voltage, but most household appliances require AC (AC) at higher voltages ).The inverter is required to convert DC (usually about 12 volts) to AC (110 volts or 220 volts depending on where you live ).When there is no sun in the night or cloudy days, there will be no electricity.The battery is used to store excess power on sunny days and get power from the battery when the sun is not available.An additional charging controller is required to ensure that the battery is not overcharged or exhausted--This helps to extend the life of the battery.Is it possible to build a house solar system yourself?Yes, it is possible, but you will spend a lot of money if you let an installation company do the job..You can do all the work yourself, thus eliminating the cost of hiring a professional for installation.However, if you have no technical mind, it is a good idea to hire an electrician to check if all the lines are correct (in some countries or states, the law may require electrical work certified by a professional ).A good solar tutorial will give you more tips on how to do the job properly.It provides you with the basic background and top knowledge about solar energy.Gap guide for installing your own home solar system.
