Monocrystalline PV modules
Monocrystalline solar panels by a number of monocrystalline silicon solar cells in a certain way assembled in a plate assembly. The photoelectric conversion efficiency of monocrystalline silicon solar cells is about 15%, the highest reached 24%, which is currently all types of solar cells higher photoelectric conversion efficiency, but the production cost is so great that it can not be a wide range And commonly used. As the single crystal silicon glass and waterproof resin are generally used for packaging, so its ruggedness, the service life of up to 15 years, up to 25 years.
(1) Since the output power of the solar module depends on factors such as solar irradiance and solar cell temperature, the measurement of the solar cell module is performed under standard conditions (STC). The standard conditions are as follows: Atmospheric mass AM 1.5, light intensity 1000W / m2, temperature 25 ℃.
(2) Under this condition, the maximum power output by the solar cell module is called the peak power. In many cases, the peak power of the module is usually measured by a solar simulator. The main factors that affect the output performance of solar modules are the following:
1) Load impedance 2) sunshine intensity 3) Temperature 4) Shadows
