Because commercial solar panels are a significant and long-term investment, business leaders who take the leap will want to know that their investment is covered. Enter a solar panel warranty.
Solar warranties mitigate the risk of faulty equipment, breakage and/or underperformance that might occur. Luckily, problems with solar panels are statistically rare, particularly when you choose solar equipment from proven solar providers like SunPower. However, it doesn't hurt to have documented assurances on your side to help you understand the long-term financial impact of solar ownership and help gain stakeholders' buy-in for a proposed solar project.
When researching commercial solar options, you'll likely encounter a wide variety of warranties with different types of coverage and term lengths, plus a lot of fine print that might make it unclear on what's covered and what's not. In addition, depending on the company, warranty definitions can vary greatly.
For example, did you know that there's a difference between solar panel product warranties and power warranties? Although the options can get confusing, it's important to understand the differences when you're deciding between solar companies.
Here's a closer look at the different types of assurances that might come with your organization's solar system.
Comprehensive third-party studies have shown SunPower panels degrade more slowly than conventional solar options.1 In fact, we guarantee that our panels won't lose more than 8% of their original power output in a 25-year timeframe when compared to 19% for conventional solar.
SunPower offers the solar industry's strongest panel power warranty 2. We cover 100% of repair or replacement costs, when many conventional solar warranties don't.3 That means labor, shipping, parts are all covered for 25 years.4
As you can see, there are good reasons why a lot of confusion exists around commercial solar panel power and product warranties. But now that you know the differences between the various types of assurances and what to expect, you'll be able to more effectively compare and contrast your options. As always, it's a good idea to work with a solar energy consultant for an additional helping hand in this area. They can help you understand the complexities of the warranties up for question. Plus, they can assist you in comparing and contrasting how different warranty terms could impact your organization financially, both in the short and long term.
