How Long Do Solar Panels Last? Solar Panel Lifespan

How Long Do Solar Panels Last

As you consider investing in a residential solar system in Australia, it’s crucial to understand the lifespan of solar panels and factors affecting their durability. We are frequently asked ‘how long do solar panels last?” In this article, we’ll delve into the elements contributing to solar panels’ longevity, discuss the impact of temperature and output deterioration on panel performance, and provide tips on maintaining efficiency through clean solar panels and working with reputable installers.
Moreover, we’ll cover the warranty period and the benefits of choosing premium, efficient, and durable solar equipment. We’ll also address the consequences of dirty or poorly maintained panels on their lifetime and energy produced, ensuring your solar system remains operational and effective for an extended period.

Solar Panel Durability: Engineered to Withstand the Elements

Modern solar panels are designed to last longer and endure extreme weather conditions, such as heavy rain, hail, strong winds, and even snow loads. Panels typically feature a robust aluminium frame, a tempered glass surface, and high-quality solar cells encased between layers of protective material, ensuring they don’t stop producing electricity under challenging conditions.
Although solar panel performance warranty and solar panel degradation rates differ among manufacturers, the rule of thumb is that energy output may slightly decrease per year due to natural deterioration. Factors like strain, shade, or cold temperatures can accelerate this deterioration. To guarantee the best capacity and energy output for your system, it’s vital to make a comparison between reputable brands known for producing high-quality products.
Moreover, it’s essential to work with an experienced and accredited solar installer to avoid any faulty installation that may affect your panels’ performance. As solar panels have no moving parts, the likelihood of significant issues occurring is minimal. However, ensuring proper installation and maintenance will save you money and time in the long run. Regularly checking for any signs of damage, such as cracks or discolouration, can serve as an indicator of potential problems and help extend your panels’ lifespan beyond 10 years, while promoting clean energy production.

Avoiding Solar Panel Degradation: Solar Panel Lifespan

Solar panels are designed with longevity in mind, with numerous manufacturers providing warranties spanning 25 years or more. In fact, research indicates that top-notch solar panels can continue functioning efficiently for over 30 years. Solar panels will inevitably experience a gradual decline in efficiency due to natural wear and tear, but this reduction is typically quite minor – approximately 0.5% to 1% annually.
Besides the solar panels, other components of a solar system, such as inverters and mounting systems, may possess shorter lifespans. Generally, these components are accompanied by their own warranties, typically lasting between 5 and 15 years. It’s vital to examine the warranty terms and conditions for each aspect of your solar system and collaborate with an installer who supports their products and workmanship.

Making Solar Panels Last Longer With Regular Maintenance

To prolong your residential solar installation’s lifespan and maintain its efficiency, regular upkeep is essential. Fortunately, solar systems generally require minimal maintenance. Here are some maintenance practices to keep your system in top shape:

Cleaning Your Solar Panels

Over time, solar panels can accumulate dirt, dust, and debris, which can reduce their efficiency. To ensure your solar panels maintain peak performance, clean them regularly with a soft brush and water or a mild detergent if needed. Stay away from abrasive materials and high-pressure water, as they may cause damage to the panels.

Inspecting Your Solar System

It’s essential to regularly check your solar system for any signs of wear, damage, or loose connections. If you spot any problems, reach out to your solar installer as soon as possible to address the required repairs or maintenance.

Monitoring Your Solar System’s Performance

Monitor your solar system’s performance to ensure it’s operating efficiently and generating the expected amount of energy. Many modern solar installations include monitoring software, making it easy to track energy production and identify potential problems.

The Role of Proper Installation in Solar System Longevity

The proper installation of your solar system plays a crucial role in ensuring its longevity and optimal performance. When selecting a solar installer, opt for a company with a proven track record of successful installations, satisfied customers, and accreditation, adhering to industry best practices. Correctly installed solar systems save money in the long run and promise efficient energy production.
During the installation, make sure that the system components, such as the roof rack, battery, and electrical wiring, are securely in place. There should be no exposed wires, loose joints, or improper use of glue, as these could be an indication of substandard work that may lead to deterioration and eventually degrade the system. Regular inspections of the solar installation, along with timely replacement or maintenance of any deteriorating components, will help extend the life of your solar system and ensure continuous energy production.

Preparing for the Unexpected: Insurance Coverage

To further protect your investment in a solar installation, consider obtaining insurance coverage. Many home insurance policies now cover solar systems, but it’s essential to review your policy’s terms and conditions to ensure adequate coverage. Having insurance can provide peace of mind and financial protection in the event of unforeseen damage or loss.
