Solar power continues to shine as a sustainable energy solution. One question may pop into your mind: How long does a solar power system last? Have you ever thought about it? Perhaps, not. Investing in solar panels is a big decision -after all, that's not a little sum. You should know how much time it will last to make a wise decision. You have to determine if it's worth it for you. In this blog, we will find out how long solar systems last and whether they are worth the investment.
An average solar panel is designed to last 25 to 30 years. This doesn’t mean that your panels will stop working after this period, but that you will notice a decrease in efficiency after this time. Solar panels lose about 0.5% to 1% of their efficiency every year. So, by the end of 25 years, they will be working at 75% to 85% of their original capacity.
To make it simple, your solar panels can still produce electricity, but the amount will be lower than when they were brand new. This is for all machinery not just solar panels.
Do you think it's just the solar panels? No, there are many parts of a solar system. It includes other components, and all of them may have a different expected lifespan:
1. Inverters: These will last for 10 to 15 years. Modern string inverters or microinverters may come with extended warranties. No matter what it is they will need to be replaced once or twice during the life of your panels.
2. Batteries: If you’re using a battery storage system, expect them to last 5 to 15 years, It can also last longer if it's used in a good way.
3. Mounting Systems: These are often designed to last 25 years or more as they’re built to stand against harsh weather conditions.
The quality of your solar panels, solar inverters, and mounting system matters a lot. Premium panels from a reputable manufacturer would always last longer than any cheap manufacturer's products. They will degrade at a slow rate.
Poor installation can shorten the lifespan of your system. Panels need to be tightly mounted. They should be in optimal positions to avoid unnecessary wear and tear from wind, water, or debris.
Solar panels are designed to stay safe from harsh weather, but extremely harsh conditions like heavy snow, or hurricanes can cause damage. Plus, prolonged exposure to high temperatures can make them less efficient.
A well-maintained solar power system will last longer than a system that is never looked back. Regular cleaning and prompt repairs can prevent minor issues from turning into huge problems.
If your system is consistently running at its peak capacity, the wear and tear on inverters and other components can degrade it.
Want to ensure your solar investment pays off? Follow these tips to keep your system running smoothly for as long as possible:
Don’t cut corners when purchasing solar panels and other equipment. Research brands, check reviews, and ensure your panels come with a robust warranty—ideally 25 years or more.
Always go for experienced, certified installers who understand local weather conditions and building codes. A professional installation minimizes the risk of future issues.
Schedule annual inspections to check for potential issues like loose connections, dirt accumulation, or minor damage. Clean your panels to remove dirt, bird droppings, or leaves that could block sunlight.
Many solar systems come with monitoring tools. Keep an eye on your system’s performance, and if you notice a drop in efficiency, get it checked.
If you live in an area prone to hurricanes or hail, consider installing protective covers or reinforced mounting systems to shield your panels during extreme weather.
Yes! Warranties are a sensitive part of a solar power system. Most manufacturers will give you two types of warranties:
●1. Performance Warranty: Guarantees that the panels will produce a certain percentage of their rated capacity over a specified time (usually 25 years).
●2. Product Warranty: Covers any defects in materials or workmanship that are valid for 10 to 25 years.
Solar panels will not stop working after their warranty expires. They will continue to produce electricity for many years. However, it would be at a lower efficiency. Many systems installed in the 1990s are still working today, even if they’re not as efficient as the latest models.
At this stage, you can think about upgrading to more advanced technology. Modern panels are efficient and smaller. It means you can generate the same amount of power with a smaller number of panels.
When solar panels reach the end of their useful life, they can be recycled. Companies are developing processes to recover valuable materials present in them. These include silicon, glass, and metals. This recycling will make solar an even more sustainable energy choice.
Solar power systems are a durable, and eco-friendly energy solution that can last 25 to 30 years. You can increase the lifespan with proper care. For this, you must invest in a high-quality solar system that has good components. It should be professionally installed so you can increase the lifespan and efficiency of your system. While your panels will eventually degrade, their long-term benefits make them a good option.
