Industry-Leading 25-Year Solar Warranty 

Home Solar Guarantee

Solar panels are a significant investment, and you deserve a solid protection plan. That’s why we back our solar installations with an industry-leading, 25-year warranty. Our solar panel warranty is designed to provide comprehensive, long-term protection for your solar energy system, and it comes standard with every solar system we install.  


Many of the solar products we install also carry their own manufacturer warranties:

  • SunPower solar panels – 25-year power, product, and service warranty 

  • SolarEdge inverters – 12-year warranty can be extended to 20-25 years depending on the model

  • LG Chem solar battery – 10-year product warranty 

Home Solar 10-Year Performance Guarantee

Our optional, Signature Home Solar 10-year Performance Guarantee, ensures that you will never have to worry about your solar energy system’s performance. Your home solar PV system is guaranteed to produce at least 95% of the power it produced on day one for ten years!

Our guarantee also includes continuous, real-time system monitoring. If there is ever a performance problem with your solar system, we’ll be alerted right away and a technician will be dispatched to repair it free of charge.
