With the continuous advancement of solar power generation technology, Jinko Solar panels have become the preferred photovoltaic products for many families and businesses due to their high efficiency, stability, and environmental protection. However, like any technological product, solar panels may also fail during use. Understanding common fault types and troubleshooting methods can not only extend the service life of the panels but also ensure the efficient operation of the photovoltaic power generation system. This article will introduce the common fault types of Jinko Solar panels in detail, and provide effective troubleshooting and solutions to help users quickly locate problems and solve them.

1. Common fault types of Jinko Solar panels

1.1 The panels do not generate electricity or low-power

This fault is one of the most common. Users may find that even if the weather is clear, the power generation of the panels is still not ideal, or even no power is generated at all.

Possible reasons:

Insufficient light: The power generation of Jinko Solar panels is closely related to the intensity of light. If the shadow at the installation location is too large or the weather is cloudy, the power generation of the panels will naturally decrease.

Damaged panels: Damage to the surface of the panels or failure of internal components may cause the failure to generate electricity normally.

Wiring problems: Loose wiring or poor contact of the panels will cause the current to not flow normally, thus affecting power generation.

Inverter failure: The inverter is an important component that converts direct current into alternating current. If there is a problem with the inverter, the power generated by the solar panel cannot be converted into effective power.

1.2 Dirty or dusty surface of the solar panel

If dust, stains or leaves accumulate on the surface of the solar panel for a long time, it will significantly affect its light absorption efficiency, resulting in a decrease in power generation.

Possible causes:

Dust accumulation: High wind speed or dry climate can cause dust to accumulate on the surface of the solar panel, affecting its light absorption.

Pollutant coverage: Substances such as bird droppings and gum may adhere to the surface of the solar panel, and in severe cases, they may even form stains that cannot be removed.

1.3 The temperature rise of the solar panel is too high

The solar panel may experience excessive temperature rise in hot weather, which will not only affect its efficiency but also may cause long-term performance degradation or even damage.

Possible causes:

Improper installation position: If the angle of the solar panel installation is not appropriate, the heat dissipation effect is not good, which is easy to cause excessive temperature rise.

Poor ventilation: There is a lack of sufficient air circulation around the installation area, resulting in the inability of the solar panel to effectively dissipate heat.

1.4 Cracks or damage to panels

Long-term use or external environmental influences may cause cracks or damage to Jinko Solar panels, especially in extreme weather (such as hail, strong winds, etc.).

Possible causes:

External impact: Panels are hit hard during transportation or in extreme weather, which may cause glass cracks or damage to internal battery chips.

Improper installation: If the panels are not properly fixed during installation, they may also be damaged by wind or other external forces during use.

1.5 Panel connection problems

Solar panel connection problems, especially loose or short-circuited wiring, may prevent the current from being transmitted normally, thus affecting the overall performance of the system.

Possible causes:

Loose wiring: If the wiring is not firmly fixed during installation, it may become loose after long-term use.

Wiring short circuit: Due to improper connection of the panel or harsh use environment (such as moisture or corrosive substances), the wiring may short-circuit, affecting the current transmission.

1.6 Inverter failure

Inverter failure often causes solar panels to not work properly because the inverter is responsible for converting the direct current generated by the panel into an alternating current that can be used by the home or business.

Possible causes:

Aging inverter: After long-term use, the efficiency of the inverter may decrease, causing it to not work properly.

Inverter setting problem: Incorrect inverter configuration or improper installation may also cause the inverter to not work properly.

2. Jinko Solar Panel Troubleshooting Method

2.1 Check the lighting conditions

First, make sure the panel is in full sunlight. If you find that the weather is cloudy, or there are buildings or trees above the panel blocking the sunlight, you can adjust the angle or position of the panel to ensure that it gets more sunlight.

2.2 Check the cleanliness of the panel surface

Regularly check whether there is dust, stains, or other obstacles on the surface of the panel. If the surface of the panel is found to be dirty, it should be cleaned immediately. Use a soft cloth and clean water to clean the surface of the panel, and avoid using corrosive detergents. Especially in dry seasons, the cleaning frequency can be appropriately increased.

2.3 Check whether the panel is damaged

Check whether the surface of the panel is cracked, broken, or otherwise obviously damaged. If damage is found, contact a professional for repair or replacement.

2.4 Check the wiring and contact points

Check whether the wiring of the solar panel is firm and whether the contact points are loose or corroded. Make sure that all connections are tight and there is no short circuit. If necessary, you can use a multimeter to test whether the current is normal.

2.5 Test the inverter function

Inverter failure is one of the common causes of low power generation. Check whether the inverter is working properly. You can confirm its status by observing the indicator lights on the inverter or using the inverter's monitoring system. If the indicator light shows abnormality or the system has a fault code, you should perform corresponding troubleshooting according to the inverter's instructions.

2.6 Check temperature and heat dissipation conditions

If the temperature of the solar panel is too high, you should check whether its installation environment has sufficient ventilation. Make sure there is an appropriate gap between the solar panels to facilitate air circulation and help heat dissipation. If the temperature rise is found to be too high, you can try to adjust the installation angle of the solar panel or redesign the layout of the solar panel.

2.7 Regular professional inspections

For large photovoltaic systems or home users, regularly invite professional solar technicians to conduct inspections and maintenance. Professionals can use more precise instruments and equipment to detect the performance of the panels and the operation of the inverter to ensure the normal operation of the system.

Jinko Solar panels are widely used around the world for their high efficiency, reliability, and long life. However, during long-term use, the panels may face some common faults. By regularly checking the working status of the panels and troubleshooting them in time, users can extend the service life of the system and maximize the efficiency of solar power generation. I hope that the troubleshooting methods provided in this article can help users solve the problem and ensure that Jinko Solar panels can stably and efficiently provide clean energy for homes or businesses. If you encounter problems that are difficult to solve, it is recommended to contact professional technicians for inspection and maintenance.
