Solar Home Lighting System The Advantages

Solar Home Lighting System Household power generation system is generally composed of solar cell components of the photovoltaic matrix, solar charge and discharge controller, battery pack, off-grid inverter, DC load and AC load and so on. If the output power is AC 220V or 110V, Solar Home Lighting System also need to configure the inverter. Photovoltaic array in the case of light will be converted into electrical energy, through the solar charge and discharge controller to the load power supply, while charging the battery; in the absence of light, through the solar charge and discharge controller from the battery to the DC load power supply, Solar Home Lighting System At the same time the battery also directly to the independent inverter power supply, through the independent inverter inverter into alternating current, to the AC load power supply.

Photovoltaic power generation is a technique that utilizes the photovoltage effect of the semiconductor interface to convert light energy directly into electrical energy. Solar Home Lighting System The key component of this technology is solar cells. Solar cells through the series after the package protection can form a large area of the solar cell components, and then with the power controller and other components to form a photovoltaic power generation device. The advantages of photovoltaic power generation are less subject to geographical constraints, because the sun shines on the earth; PV system also has a safe, reliable, no noise, low pollution, Solar Home Lighting System no need to consume fuel and erection of transmission lines can be local power supply and short construction cycle advantages.

The photovoltaic power generation system is mainly composed of solar panels (components), controllers and inverters. They are mainly composed of electronic components and do not involve mechanical parts. Therefore, the photovoltaic power generation equipment is extremely refined, reliable and stable. Easy maintenance. In theory, photovoltaic power generation technology can be used for any need to power the occasion, Solar Home Lighting System up to the spacecraft, down to home power, large to megawatt-class power station, small to toys, photovoltaic power everywhere. Solar photovoltaic power generation is the most basic components of solar cells (chip), monocrystalline silicon, Solar Home Lighting System polysilicon, amorphous silicon and thin film batteries. Single crystal and polycrystalline battery with the largest amount of amorphous batteries for some small systems and computer auxiliary power and so on.

Domestic crystalline silicon cell efficiency of 10 to 13%, foreign similar products efficiency of about 18 to 23%. A solar cell composed of one or more solar cells is referred to as a photovoltaic module. Photovoltaic power generation products are mainly used for three major aspects: First, Solar Home Lighting System to provide power for non-electric occasions, mainly for the majority of non-electric areas of residential production to provide electricity, as well as microwave relay power, communication power, etc., in addition to some mobile power and Standby power supply; the second is solar energy products, such as various types of solar charger, Solar Home Lighting System solar street lights and solar lawn, etc .; third is the grid power generation, which has been a large area in developed countries to promote the implementation. China's grid-connected power generation has not yet started, but the 2008 Beijing Olympic Games part of the electricity from solar power and wind power to provide.

Solar Home Lighting System Factors to consider:

1, where is the solar power generation system used? What is the solar radiation situation?

2, the system load power how much?

3, the system's output voltage is the number of DC or AC?

4, the system need to work every day how many hours?

5, if encountered no sunshine rainy weather, the system needs to supply power for several days?

6, the load situation, pure resistance, capacitive or inductive, start the current how much?

7, the number of system requirements.
