How To Understand Solar Power Simply?
Solar power is divided into solar thermal power and photovoltaic power. Generally speaking, solar power generation refers to solar photovoltaic power generation, referred to as "photoelectricity" for short. Photovoltaic power generation is a technology that uses the photovoltaic effect of a semiconductor interface to directly convert light energy into electrical energy. The key element of this technology is solar cells. The solar cells can be packaged and protected after being connected in series to form a large-area solar cell module. A photovoltaic power generation device can be formed by adding a power controller and other components.
Theoretically, photovoltaic power generation technology can be used in any situation where power is needed, from spacecraft to home power, from megawatt-scale power stations to small toys. The most basic elements of solar photovoltaic power generation are solar cells (slices), including monocrystalline silicon, polycrystalline silicon, amorphous silicon, and thin-film batteries. Among them, single crystal and polycrystalline batteries use the most, and amorphous batteries are used in some small systems and calculator auxiliary power. The efficiency of domestic crystalline silicon cells in China is about 10 to 13%, and the efficiency of similar products in the world is about 12 to 14%. A solar panel consisting of one or more solar cells is called a photovoltaic module. Photovoltaic power generation products are mainly used in three aspects: one is to provide power for non-electricity occasions; the other is solar daily electronic products, such as various types of solar chargers, solar street lights and solar grass lamps; This has been widely implemented in developed countries. By 2009, China's grid-connected power generation has not yet been fully promoted. However, some of the electricity used in the 2008 Beijing Olympics was provided by solar power and wind power.
It is predicted that solar photovoltaic power generation will occupy an important seat in world energy consumption in the 21st century, not only replacing part of conventional energy, but also becoming the main body of world energy supply. It is estimated that by 2030, renewable energy will account for more than 30% of the total energy structure, and solar photovoltaic power generation will account for more than 10% of the world's total power supply; by 2040, renewable energy will account for the total More than 50% of energy consumption, solar photovoltaic power generation will account for more than 20% of total electricity; by the end of the 21st century, renewable energy will account for more than 80% of the energy structure, solar power generation will account for more than 60%. These figures are sufficient to show the development prospects of the solar photovoltaic industry and its important strategic position in the energy field.
How To Build A Home Solar Power System?
Installing a system capable of generating electricity is very simple and requires five things:
2. Solar mounting system
4. Solar inverter
5. Meters installed by the grid company
Explain here the photovoltaic inverter: the electricity generated by solar panels is direct current, and home appliances cannot be used directly, and must be converted into alternating current by the inverter before being used at home.
