The warranty of the15W portable solar panelcovers components, inverters, devices and various other parts. Owners always hope to be effectively guaranteed throughout the life cycle of the entire solar energy system. They know that it is important to select the correct components and inverters, and it is also important to install these components correctly. But when it comes to warranty, reality always falls short of expectations.

If the solar energy system stops working for some reason or encounters other problems, the owners all hope that the suppliers can cover them up. This involves the warranty issues of these items. In practice, as a photovoltaic system supplier, four separate warranties need to be considered.

1. Ensure the functionality of components

The general requirement for ensuring the functionality of solar panels is 25 years, although some manufacturers extend the warranty period to 30 years. When device companies talk about a 25-year warranty for 15W portable solar panels, they generally only consider their functions and do not include other aspects of the system or the panels themselves, and more component suppliers promise 20 years.

2. Warranty for component products

Generally, unlike functional guarantees, the warranty period for most component products is 5 to 10 years, depending on the company of the device component and the products it supplies. This is far from ensuring component functionality and is even shorter, yet many people wrongly believe that component product warranties are the same as component functionality warranties. This might lead them to think that the scale of their guaranteed coverage is larger than the actual coverage, and the coverage period is also longer.

3. Inverter warranty

The warranty period for inverters is almost always five years, but sometimes there are some upgrade options that extend the warranty period to ten years or even longer. These upgrades are generally not free and may be provided at the time of sale or installation. If the cost of other guarantees is low, a higher value can be provided, but it is important to understand how much the cost will increase.

4. Ensure the installation

The warranty of the device is provided by the installer rather than by the manufacturer of the 15W portable solar panel or other system components. Generally, this warranty period is one or two years. In some cases, the warranty period for the device may be 10 years, but this is not common. Asking the installation personnel about their warranty period is crucial for understanding the common sense of the system.

What warranty terms should you ask the installation personnel about?

Specifically, before choosing the installation company for your 15W portable solar panel and inverter, be sure to inquire about the warranty situation from the company. The device program might say it has a 25-year warranty, but it is important to know whether it can cover all the contents. Although it may include component functions, the warranty period for other aspects might indeed be much shorter. It is very important to have an accurate understanding of the products and services you have obtained.

Who should you talk to about product issues or safety hazards?

If you encounter product problems or find that you think there are safety hazards, the first step is usually to contact the installation personnel. They have a very good understanding of the work they have completed for you and also have all the information about the manufacturers of the installed products. Whether your components or inverters are still under warranty or not, it is very important to deal with safety hazards and other issues in a timely manner.

Take the initiative to learn photovoltaic operation and maintenance

Selecting suitable installation providers, component manufacturers and inverter suppliers is undoubtedly the most crucial quality link in a solar energy system, but it does not represent the entire operation that follows. During operation, there is often a decline in functionality caused by non-product factors, and the power generation is lower than expected. The owner needs to proactively learn some common sense about photovoltaic operation and maintenance.

Moreover, the update of photovoltaic technology is advancing at an astonishing pace. Some design issues of products may be beyond the expectations of even product suppliers and installers at the initial stage of installation, but there are often some new technologies that can make up for them later on.

For instance, for the owners of commercial and industrial rooftop photovoltaic power stations, it is a common occurrence that the power generation does not meet expectations, and this is often caused by the most common problems such as dust accumulation and mud belts on the frame, which are not within the scope of the system's quality assurance.

Service providers often recommend that property owners use frequent cleaning to handle this issue themselves. However, if property owners are often concerned about the industry, they will know some of the latest small innovations, such as automatic drainage and sludge removers, which can solve the big problems of dust accumulation and sludge belt obstruction at a very low cost. However, since such small creative ideas are often not the mainstream skills that the photovoltaic industry pays the most attention to, it is necessary for the owners to learn and understand them by themselves.
