As the global demand for clean energy continues to grow, solar power generation, as a green, environmentally friendly and sustainable form of energy, is favored by more and more families and businesses. As an industry-leading brand, Jinko Tiger solar panels have gained wide recognition in the market for their high efficiency and durability. However, users often care about a key issue in actual use: What factors affect the power generation of Jinko Tiger solar panels? This article will deeply analyze the main factors affecting its power generation efficiency and power generation, and help users to purchase and use solar panels more scientifically to achieve the best power generation effect.
1. Solar radiation intensity
The fundamental power of solar panel power generation comes from solar radiation, and the radiation intensity directly affects the output power of the panel. The higher the radiation intensity, the more light energy the panel receives, and the greater the power generation. Jinko Tiger panels use high-conversion efficiency PERC or TOPCon technology, which can use light energy more effectively, but still cannot break through the limitations of natural light.
Geographical location: Areas near the equator have long sunshine hours and high radiation intensity throughout the year, which are suitable for solar power generation. On the contrary, in areas with higher latitudes, especially in winter, the light is reduced and the power generation decreases.
Seasonal changes: In summer, the daytime is long, the sun angle is high, and the power generation efficiency is high; in winter, the sunlight is weak and the daytime is short, and the power generation is reduced.
Weather conditions: Cloudy, rainy or hazy weather will significantly reduce the radiation intensity, which will affect the power generation effect.
2. Installation angle and direction
The installation angle and orientation of Jinko Tiger solar panels are crucial for light reception. Even if the panel itself is efficient, if the installation angle is unreasonable, it will cause a significant drop in power generation.
Tilt angle: The tilt angle of the panel should be adjusted according to the latitude of the location and seasonal changes. Generally speaking, when fixed, the angle is approximately equal to the local latitude angle, which can maximize the power generation throughout the year.
Orientation selection: In the northern hemisphere, the panel should face south as much as possible to ensure the best reception of solar radiation throughout the day. Installation facing east or west will result in insufficient power generation in the morning and evening, affecting the overall power generation.
Shading factors: Surrounding buildings, trees or other obstacles blocking the panel will cause local shadows, which will greatly affect the panel's power generation efficiency. Although Jinko Tiger panels have a certain anti-shading design, shading cannot be ignored.
3. Temperature influence
The power generation efficiency of solar panels will decrease as the temperature rises, which is determined by physical properties. Jinko Tiger series panels use advanced semiconductor materials, with low temperature coefficients and relatively stable performance, but they will still be affected by high temperatures.
Temperature coefficient: The temperature coefficient of Jinko Tiger panels is generally around -0.3%/℃, which means that the power output will decrease by about 0.3% for every 1 degree Celsius increase.
Ambient temperature: When the sun is strong in summer, the surface temperature of the panel may be as high as 50℃ or above, resulting in a decrease in power generation efficiency. During installation, ensure that there is good ventilation and heat dissipation space on the back of the panel to reduce the impact of temperature.
Cooling measures: By reasonably designing the mounting bracket, increasing the air circulation on the back of the panel, and even using a mounting bracket with heat dissipation function, the impact of high temperature on power generation can be effectively alleviated.
4. Panel cleanliness
Dust, bird droppings, leaves and other dirt on the surface of the solar panel will block sunlight, reduce the amount of light incident, and affect power generation efficiency. Jinko Tiger panels use tempered glass with high light transmittance, but if they are not cleaned for a long time, it is difficult to maintain optimal performance.
Dust accumulation: Especially in areas with frequent sandstorms or severe air pollution, the panel surface is seriously dusty, which will cause a 5%-15% or even more drop in power generation.
Regular cleaning: It is recommended to clean the panel surface every quarter or half a year according to the local environment, using a soft cloth and clean water to wipe and avoid scratching the glass surface.
Rainwater self-cleaning: Some high-end panels have anti-fouling coatings, and rainwater can help wash away some dust, but this cannot completely replace manual cleaning.
5. Component aging and maintenance status
Although Jinko Tiger solar panels have good durability and long-term performance guarantees, as the years of use increase, the components will gradually age and the power generation efficiency will also decrease.
Photovoltaic component aging: Generally, photovoltaic components decay by about 0.3% to 0.7% per year. Even Jinko Tiger's high-quality components will experience a slight performance decline after long-term use.
Wiring and inverter maintenance: In solar energy systems, in addition to the panels themselves, the status of equipment such as inverters and junction boxes also affects power generation. Inadequate maintenance may lead to reduced system efficiency or even failure.
Regular inspection: It is recommended that users regularly inspect the system voltage, current and power generation curves to detect abnormalities in time and ensure the overall system operates stably and efficiently.
6. Inverter efficiency
Jinko Tiger solar panels generate direct current, which needs to be converted into alternating current by an inverter for use in homes or power grids. The performance and efficiency of the inverter directly affect the final power output.
Inverter efficiency: The efficiency of high-quality inverters can reach more than 98%, while low-quality inverters may only be 90%-92%, which directly affects the overall system power generation.
MPPT technology: Modern inverters mostly use maximum power point tracking (MPPT) technology, which can dynamically adjust voltage and current to maximize the panel power generation efficiency.
Inverter matching: The inverter needs to match the panel power to avoid power waste or overload, which affects the power generation and equipment life.
7. Environmental factors and system design
In addition to the above main influencing factors, environmental and system design details cannot be ignored.
Shadow effect: Local shadows will cause a sharp drop in the power generation of series components. Jinko Tiger panels support segmented optimization design, such as with micro-inverters or power optimizers, which can alleviate the impact of shadows.
System layout design: Reasonable wiring and component configuration to avoid cable loss and resistance, and ensure power transmission efficiency.
Weather extreme events: Extreme weather such as storms and hail may damage panels, reduce service life and power generation, so it is particularly important to choose Jinko Tiger panels with high weather resistance.
In summary, the power generation of Jinko Tiger solar panels is affected by many factors, including the natural environment (light intensity, temperature, weather), installation parameters (angle, orientation, shading), panel conditions (cleanliness, aging), system equipment (inverter efficiency, system design), etc. Understanding and optimizing these factors is the key to maximize the power generation potential of Jinko Tiger solar panels.
