How Long Do Solar Panels Last?
Does your home or business use a large amount of electricity? If so, you’re looking for inexpensive energy to power your space.
One of the most popular choices is solar panels. But have you ever wondered how long do solar panels last?
Floating solar panels are a more reliable way to harness the sun’s energy than the panels you may have seen on rooftops. Read on if you want to know more about these better models and their potential lifespan.
Here is everything you need to know about the lifespan of solar panels.
What’s the Average Lifespan of Solar Panels
Generally speaking, if your solar panel is well cared for, you can expect a least 25 years as a baseline for the expected lifespan. Most manufacturers also provide a warranty of between 10-20 years. With regular maintenance and system optimization, it’s possible to get more than 25 years of productive life from a solar panel.
Maintenance habits such as cleaning, testing, monitoring the solar panel and its associated elements, and scheduling any required repairs or replacements are vital to get the greatest lifespan from a solar panel system.
Factors That Affect Solar Panel Lifespans
A variety of factors can contribute to a solar panel’s productivity and either increase or decrease its lifespan. Some of those factors include:
Good quality solar panels are built with solid and reliable components, contributing to a long lifespan. They can better withstand environmental conditions such as extreme weather, dust, and oxidation.
Besides, high-quality solar panels tend to have fewer shaded dark spots. This increases their efficiency and lifetime performance.
Good-quality solar panels can last up to 25–40 years if maintained regularly. In contrast to those not of the same quality, which can reduce the lifespan by as much as 10 to 20 years.
Installing solar panels ensures that the panels are attached to the structure, facing in the correct direction, and are free of debris. Poorly installed solar panels can be subject to higher stress levels, leading to premature failure.
When a solar panel is installed poorly, it may also cause excessive wear and tear on adjacent panels. This can lead to premature failure as well. The quality of the parts used in solar panel installation also plays a role in determining the system’s lifespan.
Poorly constructed frames, fitted connectors, and leaking seals may lead to water ingress. In return, this will reduce the lifespan of solar panels.
The solar panel must be installed correctly and on a surface resilient to sunlight, wind, and rain. The ideal surface should be one that is not prone to overheating since that can damage the panel.
However, if you are considering solar for residential homes, it is best to hire professional installers. They can guarantee the safest and most durable materials are used throughout the installation.
With regular maintenance, the performance of solar panels may improve over time. It is vital to keep solar panels free from dirt and debris by cleaning and inspecting them for signs of damage.
Inspecting the attachment points and electrical contacts for dirt, rust, and corrosion is crucial, as these can lead to a decrease in energy production. Lastly, ensure that the system wiring and connections are always maintained and insulated.
Cost Considerations for Replacing Solar Panels
Replacing solar panels can be expensive, but it is often necessary to support the efficiency of a system. When considering the cost of replacing solar panels, the system’s type and size should be considered. Furthermore, the complexity of the installation and the type of panel used can make a difference.
Generally, replacing a single panel is less expensive than replacing an entire system, but for larger systems, the cost may be higher. One also has to consider the availability of incentives or rebates that can help defray some of the cost.
In most cases, energy will be saved in the long term by replacing older solar panels with newer models. In some cases, an energy audit of the system may find ways to reduce energy usage and further lower costs.
The Types of Solar Panels That Last the Longest
Monocrystalline solar panels are the most durable and can last 25-30 years with proper installation and maintenance. They are made with high-quality silicon cells and are the most efficient type of panels as power output and can reach up to 20% efficiency. Polycrystalline solar panels are less efficient than monocrystalline ones.
But they are also a reliable type of panel, and it is estimated to last 20-25 years. Thin film solar panels, such as amorphous silicon and cadmium telluride, are less efficient.
It generally has a shorter lifespan of 10-20 years. Yet they are much more flexible and can tolerate extreme temperatures and other conditions that damage older panels.
Maintenance Tips to Extend the Lifespan of Solar Panels
Proper maintenance is key in extending the lifespan of your solar panels. The panels should also need to adjust as the seasons change to make sure they are in the best position for optimal energy production.
It is important to inspect your system and clean off debris, dust, dirt, and leaves. It is helpful to use a soft brush and a simple hose spray to clean the panels.
Also, check the wiring and connections to make sure there is no corrosion or lose wires that could affect the energy transfer. Finally, it is vital that the inverter is functioning since this is the device that converts the energy from the panels into usable power.
Find Out How Long Solar Panels Last
The longevity of solar panels depends on the type, care, and environment. On average, traditional solar panels will last 25-30 years, which can be 3-4 times the length of their warranty. Taking proper care of and monitoring your solar panels can help them last even longer.
If you are considering a solar panel system, be sure to do your research on how long solar panels last and speak to a reputable solar expert to get the best system for your needs.
