Five Frequently Asked Questions About Solar Power Generation

Five Frequently Asked Questions About Solar Power Generation

Solar energy is different from any other form of energy. This is a special moment because it’s clean and green. More importantly, it has at least two essential functions. One is that it can be used to generate electricity, and the other is that it can be used to generate thermal energy. The first is becoming increasingly popular. The following five are asked frequently.

1. What solar energy can do for us?
First, it can be used to generate electricity. Under average conditions today, people use solar cells and solar panels to generate a continuous stream and then convert the current with a generally known alternative solar inverter device. Second, it can be used in a system called generation system that generates solar thermal energy with heat from solar energy. Third, the heat can help warm somewhat. For example, can be used to heat water for a bath or other purposes. Fourth, it can be used to heat our homes and air conditioners. And more.

2. What is PV?
PV photovoltaic means. Solar panels is used for converting sunlight into electricity (direct current) and then a conversion device is used to convert direct current in the (AC) power that is used in the home. In the current conditions of PV energy production is equal to the production of solar energy, which is the mainstream of solar energy production. In addition, one of its branches PV, which is becoming increasingly popular today is distributed. This means that solar electricity can be generated in both residential and commercial buildings, and building owners do not have to rely on the grid of staff for the daily consumption of energy.

3. How solar cells produce electricity?
A solar cell is a type of semiconductor that can convert sunlight into electricity. You can directly convert sunlight into direct current, and this is the most critical in the production of photovoltaic electricity element. The most important feature thereof is that it adds a certain element such as phosphorus or crystalline silicon and boron is a perennial imbalance in the molecule of the material electric charge, to form a sort of semi-conductor material with special electrical properties . Sunbathing, especially semiconductors can produce free electric charges in directional movement, accumulate and form an electromotive force. When a driver is used to close both ends thereof, a current is produced. Therefore, electricity is generated by solar cells.

4. What are the components used in a photovoltaic system?
The system consists of solar panels, controller, battery (optional), a PV inverter and other components. The two most important parts of this are the solar panels and photovoltaic inverter (If the owner uses micro-inverters, which uses a number of them not one).

5. What are the advantages of photovoltaics?
First, sunlight is very witty, and so this form of power generation is almost endless. Second, is the environment. No need biofuels to generate electricity, and emits no carbon dioxide air pollution. It also has no sound. Third, it can be used widely. As sunlight can reach, this system can be used. Fourth, the system is not in machine components, and so it can be easily operated and maintained. Fifthly, the resources utilized are rich and can withstand many years. At least you know silicon is stored in abundance in the earth’s crust. Finally, a system of this type can be used for more than two decades. During the lifetime of crystalline silicon can reach 20 to 35 years.
