Investing in solar panels is a long term decision and warranties help ensure you can enjoy reliable renewable energy for decades to come. At SolarTherm UK, we believe in complete transparency and peace of mind for all our customers. Understanding the different types of warranties for your solar system can help you make an informed choice and protect your investment.
Product and Performance Warranties on Solar Panels
A high quality solar panel system is designed to last a minimum of 25 years, with most solar panels continuing to generate electricity efficiently for up to 40 years. At SolarTherm UK, our Bovill.tech solar panels come with an industry leading 40 year warranty, extendable to 99 years. If any of your panels stop working as expected, SolarTherm UK will arrange a full replacement of the panel.
Your panels are covered by a performance (power output) warranty, over time solar panels naturally experience a slight drop in efficiency. Our suppliers guarantee that your panels will still produce at least 80% of their original output after 25 years. If performance falls below this level, your panel can be replaced under your warranty, ensuring your energy savings remain protected.
Product Warranties on Solar Inverters
At SolarTherm UK we only install the highest quality products, and your solar inverter is no different. The warranty on your solar inverter ranges from 5 years to 12 years depending on the brand and model. If your inverter stops working correctly in this period, it will be replaced with a new one or equivalent.
Product Warranties on Solar Batteries
Voltsmile batteries come with a 10 year product warranty, protecting your investment so you receive high efficiency and power for a minimum of 10 years.
SolarTherm UK Installation Guarantee
A high quality solar system deserves a high quality installation, and all SolarTherm UK installations come with a two year workmanship warranty. If any issues arise during the two years that are due to the installation, our team will repair or replace and resolve your issue. We take full responsibility for the safety and reliability of every system we install, giving you complete confidence in your investment.
