How long do solar panels last?
Both polycrystalline and monocrystalline solar panels have a lifespan of more than 25 years. While some claim that monocrystalline panels degrade faster, the type of silicon solar cell used in your solar panels usually has no effect on their useful life. The silicon in solar panels is used to convert sunlight into electricity by converting photons into electrons. Power output degrades over time, by about 0.8% per year. So, in year two, your panels should produce 99.2% of their original output, 98.4% in year three, and so on. Furthermore, solar panel warranties help to establish expectations about how long your solar panels and other equipment, such as inverters, may last.

Frequently Asked Questions
Q: How do solar panels work?
A: Solar panels work by converting sunlight into electricity through a process called the photovoltaic effect. The panels are made up of solar cells that contain semiconductors, usually silicon. When sunlight hits the solar cells, it excites the electrons in the semiconductors, generating an electric current.
Q: What are the benefits of solar panels?
A: Solar panels offer several benefits, including reduced electricity bills, lower carbon footprint, and energy independence. They provide clean and renewable energy, contribute to the fight against climate change, and can even increase property value.
Q: Are solar panels expensive?
A: While solar panel installation costs can vary, they have become more affordable in recent years. The long-term savings on electricity bills and potential incentives or tax credits can offset the initial investment. Additionally, as technology advances, solar panels are becoming more cost-effective.
Q: How long do solar panels last?
A: Solar panels typically have a lifespan of 25 to 30 years. However, many manufacturers offer warranties for up to 25 years, ensuring the panels' performance and durability over an extended period.
Q: Do solar panels require maintenance?
A: Solar panels are generally low-maintenance. Regular cleaning to remove dirt and debris, as well as checking for any shading issues or damage, is recommended. Additionally, monitoring the system's performance and ensuring proper electrical connections can help optimize its efficiency.
Q: Can solar panels work during cloudy days?
A: Solar panels can still generate electricity on cloudy days, although their efficiency may be reduced. While direct sunlight produces the highest energy output, even diffused sunlight can generate a significant amount of power.
Q: What happens to solar panels during power outages?
A: During a power outage, standard grid-tied solar panel systems will automatically shut off for safety reasons. This is to prevent the electricity produced by the panels from being sent back to the grid, potentially endangering utility workers. However, some solar panel systems can be paired with energy storage solutions to provide backup power during outages.
Q: Can I install solar panels myself?
A: While it is possible to install solar panels yourself, it is recommended to hire a professional installer. They have the expertise and knowledge to ensure the panels are correctly installed, connected to the electrical system, and meet local regulations and safety standards.
