 1.What is solar power system ? 

 According to the electricity demand of the Zero Carbon Pavilion project of the Shanghai World Expo, the overall performance of the solar photovoltaic system is personalized to achieve the optimization of energy saving and environmental protection effects. Traditional fuel energy is declining day by day, and at the same time, there are about 2 billion people in the world who do not have normal energy supply. At this time, people turned their attention to renewable energy, hoping that renewable energy could change the energy structure of mankind and maintain long-term sustainable development. Among them, solar energy has become the focus of people's attention with its unique advantages. Abundant solar radiation energy is an inexhaustible, non-polluting and cheap energy source. 

 Solar power system, Also called a solar electric system or photovoltaic PV system. A power generation system that uses the photovoltaic effect of solar cells to directly convert solar radiation into electrical energy. Referred to as photovoltaic system.solar power systems use solar panels to collect photons of light from the sun and use them to create an electrical current. To learn more about solar PV systems, please continue to review our page and then you will know How Solar Power Systems Work.

 On this page, we will discuss the working principle of photovoltaic system, the feature of photovoltaic system,FAQ of photovoltaic system and where you buy the kits for solar power system. 

 2.the working principle of photovoltaic system

 During the day, under the condition of light , the solar cell modules generate a certain electromotive force, and the solar cell array is formed through the series and parallel connection of the modules, so that the voltage of the array can meet the requirements of the input voltage of the system. Then charge the battery through the charge and discharge controller, and store the electric energy converted from light energy. At night, the battery pack provides input power for the inverter. Through the function of the inverter, the DC power is converted into AC power, which is transmitted to the power distribution cabinet, and the power is supplied by the switching function of the power distribution cabinet. The discharge of the battery pack is controlled by the controller to ensure the normal use of the battery. The photovoltaic power station system should also have limited-load protection and lightning protection devices to protect the overload operation of the system equipment and avoid lightning strikes, and to maintain the safe use of the system equipment.

 3 the feature of photovoltaic system

 There are many features about photovoltaic system. In this essay we mainly share the advantages and disadvantages of it. Obviously the advantages out weight the disadvantages by the following lists. 

 3.1 The advantages of photovoltaic system.

(1). Solar energy is inexhaustible. The solar radiation energy received on the earth's surface can meet 10,000 times the global energy demand. As long as solar photovoltaic systems are installed on 4% of the world’s deserts, the electricity generated can meet global needs. Solar power generation is safe and reliable, and will not be affected by the energy crisis or unstable fuel market.

(2). Solar energy can be get everywhere, and power can be supplied nearby, without long-distance transmission, which avoids the loss of long-distance transmission lines;

(3) Solar energy does not use fuel, and the operating cost is very low;

(4)Solar power generation has no moving parts, is not easy to use and damage, and is simple to maintain. It is especially suitable for unattended use;

(5) Solar power generation does not produce any garbage, has no pollution, noise and other public hazards, and has no adverse effects on the environment. It is an ideal clean energy;

(6) The solar power generation system has a short construction period,  convenient and flexible, and can add or reduce the amount of solar power arbitrarily according to the increase or decrease of the load .

3.2 The disadvantages of photovoltaic system.

(1.) There are intermittent and randomness in ground application, and the amount of power generation is related to climatic conditions, and it is impossible or rarely to generate power at night or on cloudy and rainy days;

(2) The energy density is low. Under standard condition, the solar radiation intensity received on the ground is 1000W/M^2. When used in large format, it needs to occupy a larger area;

4.FAQ of photovoltaic system

 Q: Is there any radiation hazard from the photovoltaic power generation system?

 Answer: NO. Photovoltaic power generation system converts light energy into electrical energy according to the principle of photovoltaic effect. It is pollution-free and radiation-free. The relevant electronic devices have passed the EMC (electromagnetic compatibility) test, so there is no radiation hazard to the human body.

Q: Is there a noise hazard in the photovoltaic power generation system?

 Answer: NO. The photovoltaic power generation system converts light energy into electric energy, and the system components will not produce noise. The noise index of the inverter is not higher than 65 decibels, and there is no noise hazard. 

Q: How long is the life of the photovoltaic power generation system?

 Answer: The earliest photovoltaic power station was built in 1989, and it is 28 years ago. Except for batteries, the design life of photovoltaic power generation systems is generally more than 25 years.
