We usually think that sunlight is directly proportional to the power generation of photovoltaic systems, that is, the more sunlight is sufficient, the more power generation of photovoltaic systems. In fact, it is correct to think so, but it is not accurate enough. The power generation capacity of a photovoltaic system is determined by many factors.
Customers often call to inquire: In summer, the sunshine is strong and the sunshine time is long. Why is the power generation of photovoltaic power plants not as much as before? The most direct reason is temperature. High temperature environment will affect the working efficiency of solar panels and photovoltaic inverters.
So how can we maximize the power generation of photovoltaic systems?
1. The tilt angle of the photovoltaic module.
How much tilt is the best tilt angle? The approximate experience values are as follows:
Latitude 0°~25°, the inclination angle is equal to latitude; latitude 26°~40°, the inclination angle is equal to latitude plus 5°~10°; latitude 41°~55°, the inclination angle is equal to latitude plus 10°~15°.
2. The photoelectric conversion efficiency of solar modules.
The conversion efficiency of solar panels is a key factor affecting the power generation of photovoltaic systems. The quality of photovoltaic modules on the market is uneven. When choosing photovoltaic modules, don\'t just look for cheap prices, but also pay attention to the conversion efficiency of the modules. The conversion efficiency of polycrystalline silicon battery modules should not be lower than 15.5%, and the conversion efficiency of monocrystalline silicon battery modules should not be lower than 16%.
3. Selection of inverter.
The inverter is the core component of the photovoltaic system, because the direct current generated by the photovoltaic system must be converted into alternating current through the inverter before it can be used by the alternating load. The inverter should be selected with high conversion efficiency, high safety and low loss.
4. Daily maintenance of photovoltaic system
Main tasks: Clean up the garbage on the solar panels in time, and replace damaged solar panels in time.
5. Reasonably match the photovoltaic system.
Choosing the best accessories may not be able to build a perfect photovoltaic system. A set of high-performance photovoltaic system has to go through many experiments and system debugging, so the installation and parts replacement of the photovoltaic system must be carried out by professional technicians.
