On a ten-hour basis, one square meter of solar panels can generate 1.2 to 1.5 kWh of electricity.
The power of one square meter of solar panels is 140-150W, but solar power generation is greatly affected by sunlight. The stronger the sunshine, the longer the sunshine duration, the greater the power. generation, such as morning, noon, night, cloudy day, when raining, etc., it can produce about 1.2-1.5 kWh electricity per day.
There are many types of solar panels. One is crystalline silicon material, including monocrystalline silicon and polycrystalline silicon, the other is amorphous silicon power generation, which is not crystalline silicon. There is thin film solar energy. solar energy production. Due to the low conversion rate of amorphous solar cells, crystalline silicon solar power generation isnow more widely used.
The principle of energy production of solar panels;
A solar cell is a device that reacts to light and can convert light energy into electricity. There are many types of materials that can produce photovoltaic effects, such as: monocrystalline silicon, polycrystalline silicon, amorphous silicon, gallium arsenide, copper selenium indium, etc. Their principles of energy production are basically the same. Today, crystalline silicon is used as an example to describe the photovoltaic power production process. Crystalline P-type silicon is doped with phosphorus to obtain N-type silicon, forming a P-N junction.
When light irradiates the surface of the solar cell, part of the photons are absorbed by the silicon material; the energy of the photons is transferred to the silicon atoms, causing the transition ofs electrons and their transformation into free electrons. accumulate on both sides of the P-N junction to form a potential difference, when the external circuit is connected, under the action of this voltage, a current will flow through the external circuit to produce a certain output power. The essence of this process is: the process of converting photon energy into electrical energy.
The longitudes and latitudes of different places in the South are different, and the regional lighting conditions are also different. The battery components used in the installation of photovoltaic power generation systems are different, as are the installation methods. are different...the electricity production capacity is the same.
Basically: With the correct installation method (correct azimuth angle and tilt angle), general-purpose battery components generally generateabout 900 to 1,300 degrees of electricity per kilowatt per year (Hubei, Hunan, Jiangxi, Guangxi, Guangdong and other places are different). If a solar tracker is installed, annual electricity production can be increased by 15-35%.
