    Solar Lasts A Very Long Time

    On average, solar panels should be upgraded every 25 years, but they can last anywhere from 30-50 years after the manufactures’ warranties end coverage.

    This is a reason that banks are now willing to finance solar energy installations using mainstream financial instruments. Solar panels are now demonstrating incredible longevity. Banks and lenders know that an investment in solar will add tangible value to your property for many years to come.

    Excellent Manufacture Warrenties

    In addition, there is additional security added to the equation because high-quality, made in Washington solar products are warrantied for 25 years. Banks know that replacement parts will be provided if something goes wrong for a very long time.

    As an example, take our favorite, local Washington solar manufacturer: Silfab Solar. If the power output any solar panel falls below 80% of its rated capacity, at any time over 30 years, they will replace it for free or buy it back from you.
