How Long Is My Solar System Under Warranty?

A solar system represents a significant investment so making sure your investment is future proof is a wise move. There are different warranties for different parts of your solar system. Knowing the difference between them and what products feature the best warranties is important to ensure you are protected. Let’s look into the different types of warranties.

It’s worth noting that solar PV modules are unlikely to fail statistically. The vast majority of panels never have a fault, as there are no moving parts. They will produce clean energy for decades without any issues, that said, it’s always best to be prepared.

Almost all solar panel manufacturers offer two warranties: a performance warranty and an equipment guarantee. Its important to note that this varies from panel to panel as well as from different manufacturers.

This type of warranty guarantees that a solar panel’s production rate does not drop below an advertised amount. As an example, the SunPower performance 7 panel offers a warrantied 99% performance after the first 12 months. It also backs this up with a 30 year product and power coverage as well as a maximum annual degradation of 0.4%. This means that the 445W panel will still be producing at least 87% of its original output after 30 years!

This type of guarantee is for material defects in design, materials and workmanship that impair the performance of the module. The SunPower performance 7 has a warranty covering defects

related to workmanship and materials for a full 30 years.

All our carefully selected products offer replacement panels if their product does not perform as promised. If you do discover an issue with your solar panels it is worth bearing in mind that manufacturers require inspection and test reports to be completed before approving a warranty claim.

The inverter is the component more likely to fail when looking at the longevity of your solar system. Although it has no moving parts, it works hard every day to convert DC electricity generated by your solar panels to AC electricity you can use in your home or business. We only use top of the range inverters for that very reason.

Most manufacturers offer at least 5 years. Our preferred supplier, Fronius, provides a warranty coverage of up to 10 years for registered products. Similarly to solar panel manufacturers, inspection and testing is required to establish the fault and provide a replacement. We always look to minimise downtime so you keep on producing clean energy.

Whereas product warranties protect you against component related issues, workmanship warranties protect you from labour related defects. Such as those arising from the actual installation process. Our 10-year workmanship warranty is one of the longest on offer.

Our workmanship warranties include:

Solar workmanship warranties vary depending on the installer. With the help of monitoring your solar panels (in real-time) we can assist if any faults occur throughout the lifetime of your system. Our warranty doesn’t stop after the installation, we offer a comprehensive post-installation service giving you peace of mind for your investment.
