Thinking about harnessing solar power to lower your energy bills, reduce your carbon footprint, and accelerate the energy transition? As you delve into the world of solar panels, one crucial aspect to consider is the warranty that comes with your solar panel system.
A solar warranty is your safety net, providing assurance that your investment will perform as expected and offering protection against potential issues that may arise over time. Here are a few things you need to know to make an informed decision about whether a solar panel warranty is necessary for you.
The Different Types of Solar Warranties
Performance Warranty: This guarantee ensures that your solar panels will maintain a certain level of performance over time, typically around 80-90% of their original output capacity over 25 to 30 years.
Product Warranty: Solar panel product warranties cover defects in materials or workmanship. A product warranty assures that your solar panels will be repaired or replaced if they fail due to manufacturing defects within the specified warranty period, typically ranging from 10 to 25 years.
Inverter Warranty: Inverters, crucial components of solar PV systems, often come with their warranties, lasting from 5 to 25 years. These warranties cover the repair or replacement of inverters in case of malfunction.
Installation Warranty: Some installers offer warranties on the workmanship of the installation. This will ensure that your system is set up correctly and addressing any issues arising from improper installation. These warranties typically last for a few years.
What A Solar Warranty Covers
Performance Guarantees: Assure a minimum level of electricity production over the system’s lifespan.
Product Defects: Cover issues like delamination, cracks, or premature degradation of solar panels.
Power Output: Guarantee that panels will maintain a certain percentage of their rated power output over time.
Inverter Malfunction: Cover the repair or replacement of inverters in case of malfunction.
Workmanship: Ensure that you install the solar panel system correctly and that it performs as intended.
Need a Solar Panel Warranty?
While solar panel warranties offer valuable protection, whether you need one depends on various factors:
System Longevity: Consider the expected lifespan of your solar panel system. If you plan to stay in your current home for decades, a warranty can provide peace of mind.
Quality of Panels: Higher-quality panels often come with longer warranties. If you’ve invested in premium panels, a warranty can safeguard your investment.
Local Conditions: Living in an area prone to extreme weather or environmental factors can affect your system’s performance. In such a scenario a warranty may be particularly valuable.
Installer Reputation: Choose a reputable installer with a proven track record to minimize the risk of installation-related issues.
Choosing the Best Solar Panel Warranty Period
The warranty period for solar panels is influenced by several factors. First and foremost, know that solar panel warranties will differ depending on the intended use (residential, commercial, industrial) and what they cover (performance, product, and/or installation of the entire system). Other factors that can influence the a property owner’s decision related to the length of (lifespan) of their solar panel warranty period include the reputation of the manufacturer, type of panel (such as monocrystalline or polycrystalline) and its quality, degradation rate, environmental conditions at the installation site, and of course, regulatory requirements. For most all solar panel warranties, proper installation by certified professionals is also required for coverage.
Final Thoughts on Solar Warranties
Before committing to solar panels, carefully review the terms and conditions of the warranty offered by the manufacturer or installer. To protect yourself, understand what coverage includes, including its duration, and any conditions or limitations that may apply. While solar panel warranties represent an additional cost, they can provide invaluable protection. A solar panel warranty also offers some peace of mind to ensure that an investment in solar power pays off for years to come.
