Solar panels do not last forever. Over their lifetime, all solar panels gradually degrade, meaning that their power production and efficiency decline.
Before investing in solar, you will want to know your potential return on investment. Fortunately, taking certain steps can help to extend the life expectancy of your panels. But exactly how long do solar panels last? Here’s what to know.
How Long Do Solar Panels Last in Nevada?
Generally, the industry standard lifespan of solar panels is 25 to 30 years. On average, panels degrade at a rate of one percent each year in service. This is typically backed up by the manufacturer’s warranty, which guarantees 90 percent of production in the first decade and around 80 percent after 20 to 25 years.
The lifespan of solar panels depends on a variety of factors. They include:
Quality of Materials
The type, quality and materials of solar panels you install have a direct impact on the performance, efficiency and lifespan of the equipment. Low-quality materials will degrade faster. On the other hand, panels that carry a manufacturer’s warranty of more than 25 years are likely to last long.
Installation
Solar panels must be installed correctly in a racking system that keeps them in place and supports them long-term. A reputable installer will ensure your solar panels are installed and wired properly. The experts may also offer maintenance checks, provide workmanship warranties and fix any issues before they become bigger problems. This will ensure your panels last as long as possible.
Climate
Solar panels perform best in sunny conditions. However, extreme heat can cause the solar panels’ materials to break down, affecting the system’s efficiency and longevity. Other weather elements that may degrade your panels faster are hail, humidity and high winds.
Maintenance
Solar panel systems last longer when properly maintained and serviced. A buildup of dirt, leaves and debris on the panels may not only cause chips and scratches on the surface but also block the sun’s rays. Basic maintenance to increase the longevity of your solar panels may involve regular cleaning and installing critter guards.
Why It’s So Important To Clean Solar Panels in Nevada
Cleaning your solar panels is a critical part of maintenance. This is particularly crucial if you live in Nevada.
Desert-Like Climate Makes Them Get Dirty Fast
Most of Nevada experiences a desert-like climate. Solar panels installed in these areas have to contend with far more dust, dirt and sand. Regular cleaning will help to protect your solar equipment from damage and improve efficiency.
Bird Droppings and Nests Can Cause Damage
Bird droppings on solar panels not only cause an unsightly mess but also block access to the sun. Without regular cleaning, the droppings will harden and stick to the panels. Also, nests built under the panels will block airflow and contribute to an increase in temperature.
Helps You Keep Tabs on the Condition of Your Panels
To protect your solar panels, be sure to hire a professional to clean them. While cleaning the equipment, the professional will inspect the system to ensure everything is working correctly. This makes for a great way to monitor the health of your solar panels.
