When it comes to using solar panels, high quality solar panels will hardly cause any major damage to the panels even if they are used in heavy snow, hurricanes, or high temperatures. However, there will still be some instances where our solar panels will have to be repaired or replaced, usually as long as there is no major damage to the solar panels that would require finding a professional. There are also some minor problems with solar panels that we can fix ourselves. Let’s take a look at the possible problems of solar panels and the related solutions.
1.1 Microcracks: This is the most common damage to solar panels, generally caused by instantaneous changes in temperature. Especially when the temperature is high at noon, cleaning the solar panel with cool water is most likely to cause micro-cracks.
On windy and rainy days, both wind and rain put more pressure on the solar panel, which may lead to deformation of the solar panel, or in severe cases, water directly inside the solar panel. Even when not in this type of weather, if the micro-cracks are not dealt with in a timely manner, they are going to continue to spread and eventually the tempered glass may come off. When this happens, short circuiting or corrosion inside the solar panel is likely to happen.
Solution: Use a rubber squeegee to apply the composite film to the area of the solar panel where the micro-cracks appear, take care to remove all air bubbles and wrinkles during the application process, and then use a hot air gun to fuse it to the surface of the solar panel. In addition to using this method, polyurethane can also be used to coat the solar panel and a rubber squeegee can be used to spread it evenly.
1.2 Damage by Rodents, Birds: Rodents and birds will walk on the surface of the solar panel and may scratch the glass panel. And they may also build nests under the solar panels, resulting in heat build-up in the solar panels. Rodents may sometimes chew on the connecting wires, causing power outages. Bird droppings may also cause a hot spot effect.
SOLUTION: Regular inspection of the solar panel may reduce the activity of small animals on the solar panel. If you find animal nests around the solar panels, be sure to clean them promptly. Consider also installing a safety net to keep small animals out.
1.3 Loose connection or faulty wiring: When your solar panel suddenly loses power generation efficiency over a period of time, you need to consider whether the connection is loose or the wiring is faulty.
You can use a multimeter to measure the voltage and resistance to determine the approximate problem of the solar panel, and if the solar panel is short-circuited, it is recommended that you directly seek professional help. If the solar panel is short-circuited, it is recommended that you seek professional help directly. If it is only a loose connection or a faulty wiring, you can try to solve it by yourself.
Solution: Wear insulated gloves and use a screwdriver to reinforce the loose connection. However, when your wiring is faulty, you will have to reconnect or replace the damaged wires depending on the connection method of the different solar panels.
1.4 Snail grain: When a black or white line pattern appears on the solar panel, it is usually called snail grain. When the snail pattern reaches 12% of the solar panel area, the power and life of the solar panel decay. This problem usually occurs after a few years of use of the solar panel, which is usually when the solar panels are manufactured resulting in solar pull-out defects. So when choosing solar panels, pay attention to check the quality of solar panels.
Solution: In fact, for with the appearance of snail grain on the solar panel. Relying on us can not be solved. But we can ask the professionals to take out the battery plate with snail grain for replacement. In the process of our use, regular inspection and cleaning the surface of the solar panel dust or debris and other measures can reduce the emergence of this problem.
If your solar panels have problems during the warranty period, you can contact the manufacturer to have them repair the solar panels for you, and they are free of charge. If you are out of warranty, you will need to pay for the repair of your solar panels. When your solar energy does not have a part to replace, you may have to pay anywhere from $20 to $500, but some areas may also charge by the hour. The exact cost of the repair will also depend on the damage to your solar panels. ,
It is not difficult to avoid some problems during the use of solar panels, and we have provided you with some common problems and solutions above. We hope to help you solve the problem when you have doubts.
