Introduction

Solar panels are a popular source of renewable energy that has gained immense popularity in recent years. They have a long lifespan and require minimal maintenance, making them a cost-effective and environmentally friendly choice for electricity generation. However, it's essential to know how long solar panels typically last and how to extend their lifetime. As Mentor Water experts, we are here to guide you on maximizing the lifetime of your solar panels.Proper solar power plant maintenance is crucial for ensuring optimal performance and longevity, and our team can provide comprehensive maintenance services to help you get the most out of your solar investment.

The Duration of Solar Panel Life

Solar panels are made to last for decades by manufacturers. The Solar Energy Industries Association (SEIA) estimates that solar panels have a 20–30 year lifespan. Some high-quality panels have a 40-year lifespan.

Even though solar panels won't completely fail after 25 years, they will become less efficient at harnessing the sun's energy to power your house due to a decrease in power generation. The rate at which solar panels deteriorate is called the solar panel degradation rate.

Panels with Extended Life Expectancy

Better solar panels last longer than less expensive ones. According to the Bloomberg New Energy Finance Corporation (BNEF), these panels are classified as Tier One. Solar panels are rated in three categories by the BNEF grading system: Tier One, Tier Two, and Tier Three. Only Tier One is described in full in the BNEF; Tier Two and Tier Three panels are not.

Manufacturers that produce Tier One panels have at least five years of expertise, a stellar reputation, and access to funding. Although Tier One solar panels are sometimes the priciest, they are an excellent investment because they have the highest power production and efficiency rating.

Tier One includes monocrystalline and polycrystalline solar panels, which are the two most common varieties. Although they cost more, monocrystalline (mono) panels provide higher power output and better efficiency ratings. Although polycrystalline (poly) panels are less expensive, they have a lower output and efficiency. Mono panels have a reduced rate of degradation since they are of higher grade. Compared to mono panels, lower-efficiency poly panels lose efficiency more quickly.

Factors That Affect Solar Panel Lifespans

Certain elements, such climate and extreme weather, have an impact on how long solar panels last and are out of your control. However, there are still methods you may use to extend the life of your solar panels.

  1. Installing Solar Panels: Installing rooftop solar panels requires sturdy racking systems. Installing the panels correctly keeps them from slipping or splitting, which could reduce their effectiveness. Skilled solar installers will fasten your panels securely to keep them from toppling off your roof. Many solar providers include a workmanship warranty covering installation. This protects homeowners from faulty installations that lead to panel or system damage. 
  2. Solar Panel Quality: Purchasing premium solar panels guards against serious deterioration and decreased productivity. Your panels will still deteriorate, but not as much as cheap solar panels. Superior solar panels yield more power, save more energy, and offer a better return on investment (ROI). Better solar cells are used in these panels to collect more sunlight for energy conversion.

Better warranty coverage is another benefit of high-quality solar panels. Most warranties last between 12 and 15 years, but for premium panels, they can last up to 25 years. The power guarantee indicated above, which safeguards the long-term production of your panels, is probably included in these guarantees.

How to Extend the Life of Solar Panels

Although solar panel deterioration cannot be stopped, there are precautions you can do to keep your solar power system safe. See how to maintain the best possible condition for your panels. 

1. Make sure your solar panels are clean: Daily upkeep for solar panels is minimal. All year long, rain keeps them clean. If you live in an area with a lot of snowfall or are surrounded by trees that drop branches or leaves on your system, you might need to clean your panels on occasion. These obstructions could reduce your panels' efficiency and lower your power production.

You'll need to hire a professional to clean your solar panels in these instances. Check with your solar installer to see if panel cleaning services are included with your warranty coverage. If not, it may be offered as a stand-alone service.

2. Schedule Maintenance Checks and Panel Servicing: Maintaining the health of your system and keeping your solar panels operational requires routine maintenance and upkeep. A lot of solar companies offer maintenance inspections in their guarantees. This ought to include every part of the solar system, such as the racking mounts, solar battery storage, and solar inverter. An efficient energy system has a lot of moving elements, therefore thorough system maintenance is crucial.

A system maintenance app that monitors the efficiency and energy production of your panels can also be included by your supplier. If you observe significant drops in your system's performance, get in touch with your solar provider.
