Solar panel warranty is usually 25 years, solar panel warranty can be divided into product warranty and performance warranty. These warranties reflect the manufacturer’s confidence in the quality of the product, in ensuring that consumers are able to use the solar panels in a long-term, effective manner, thereby promoting the widespread use of solar power technology and sustainable development.
Product Warranty: In the process of generating electricity from a solar power system, problems caused by manufacturing errors, poor quality or material failures of the solar panels are addressed by the manufacturer during the warranty period.
Performance Warranty: A performance warranty, also known as a power output warranty, ensures that the solar panels will work efficiently during the warranty period. It is normalmente for solar panels to reduce their power at a decay rate of less than 0.5% per year. However, at this stage, the manufacturer still has to guarantee that the solar panel will work at 80% of its rated power.
The solar panel warranty period refers to the solar panel manufacturer’s commitment to product quality and is an important indicator that is directly related to the lifespan and maintenance of the solar system. For consumers, they hope that every solar panel can generate electricity efficiently, but solar panels will still have some failures, and then they need solar panel warranty. The product manufacturer will provide repairs or replacements for them, reducing unnecessary expenses for consumers.
When purchasing solar panels, the product packaging or equipment usually comes with warranty labels that clearly label information such as the warranty period, warranty terms and serial number. Consumers can carefully review these labels to ensure that the warranty has not expired and that they understand the scope of the warranty. Be careful not to damage the warranty labels when cleaning the solar panels, as damage to the warranty labels may affect the warranty at a later stage.
Solar panels are usually installed by professionals before the warranty is provided, if you want to DIY installation, the manufacturer may not recognize the warranty at this time, it is likely that the warranty is invalidated.
The solar panel warranty is mainly for its function and performance issues, such as module power generation efficiency, controller circuit failure and other issues. However, damage caused by improper human operation, such as self-alteration, disassembly or failure to meet the requirements of the instruction manual, are not covered by the warranty. In particular, only authorized professional maintenance personnel can check or repair the solar panels, if the failure caused by non-authorized personnel to repair the solar panels, the same is not in the scope of repair.
The solar panel warranty is only on the solar panel itself, such as inverters and solar battery storage devices are not in the solar panel warranty, they have their own product warranty.
Even after the warranty period, if the solar panel quality problem belongs to product defect, the manufacturer may still be responsible, you can try to communicate with the manufacturer, explain the quality problem and make a claim, the manufacturer may provide repair or replacement program.
If the solar panel is out of warranty, you can still go for after-sale repair, but you need to bear the repair cost according to the actual situation. Official repairs may be more expensive, you can also directly find other professional repairers to repair, reduce repair costs and improve economic efficiency.
The lifespan of solar panels is more than 25 years. During the period of use, regular cleaning and maintenance will most likely not cause damage to the solar panels, but a reliable warranty will allow you to use solar energy with greater peace of mind.
