The industry standard for the lifespan of most solar panels is 25 to 30 years. Most reputable manufacturers offer production warranties of 25 years or more. The average break-even point for the energy savings of solar panels occurs six to ten years after installation. Solar panels, also known as photovoltaic or photovoltaic panels, are made to last more than 25 years.
In fact, many solar panels installed as early as the 1980s are still operating at expected capacity.1 Not only are solar panels remarkably reliable, but the longevity of solar panels has increased dramatically over the past 20 years, 2 In addition to decades of effective performance, many solar energy manufacturers back their products with performance guarantees in their warranties, 1.The typical lifespan of a solar panel is 25 years or more. The key to extending its lifespan is having an accredited installer and performing basic maintenance. Solar panels are extremely durable, with an average lifespan of 25 to 30 years. Manufacturers design solar panels to last for decades.
According to the Solar Energy Industries Association (SEIA), solar panels last between 20 and 30 years. Some well-made panels can even last up to 40 years. We recommend finding a reputable solar installer to ensure high-quality equipment and a reliable installation. The inspection of your solar panels can also include an inspection of the other equipment that is part of the solar installation, namely the solar inverters and the roof rack system.
Prolonged exposure to very high temperatures will reduce a panel's efficiency and decrease its ability to supply adequate energy to your home. The accumulation of dirt, pollen, leaves and bird droppings can affect the efficiency of solar panels. Monocrystalline (mono) panels offer better efficiency ratings and higher power output, but are more expensive. Ultimately, your solar panels will offset your electricity consumption for decades and significantly reduce your energy bills, but to get an idea of when you'll need to replace your system, it's important to understand industry projections and degradation rates.
In addition, solar energy systems usually have no moving parts and require little or no maintenance. Solar panel systems will show a reduced capacity to absorb sunlight and convert it into solar energy throughout their lifespan. While solar systems require little regular maintenance, some solar energy providers offer comprehensive maintenance packages over the life of their products to ensure that they continue to generate clean, affordable and reliable energy efficiently for decades. Solar panel deterioration is inevitable, but there are some steps you can take to protect your solar energy system.
To get the most out of the lifespan of your solar panel installation, it's important to understand the average lifespan of solar panels and determine if it's worth investing in a solar energy system for your home or business. The EPBT is the time it takes for a solar panel to produce enough clean electricity to “return” the energy that was used to make it in the first place. If you're thinking about storing batteries, it's important to know that your battery will last less than your solar panels. In today's solar panel industry, there isn't much room to differentiate between different types of solar panels, simplifying your choices.
Even with 25-year warranty coverage and production warranties, solar panels will eventually lose the ability to produce the right energy for your home. The factors that cause it include heat and the natural reduction in the chemical power of the panels, also known as the “degradation rate”.
