What Is a Solar Production Guarantee and Why Do You Need One?


With no moving parts, solar is one of the most durable energy-generation technologies in the world. Once installed, your photovoltaic (PV) system can last for decades with minimal maintenance. This is why solar panel manufacturers can safely offer 25-year warranties for their products.

Many reputable installers also offer workmanship warranties that protect you against malfunctions arising from improper setup. Usually lasting 5 to 10 years, these workmanship warranties are fairly common given that breakages are very infrequent within the industry.

Despite all of this protection, however, some installers also offer solar production guarantees. But what does this guarantee provide, and do you really need this additional coverage?

Solar Production Guarantee Defined

The solar industry is booming right now. And no matter where you live, there is no shortage of PV installers who would love to have your business. Competition is at an all time high.

Unfortunately, many of these installers overpromise what your PV installation will generate. By showing you exaggerated numbers about energy output and ROIs, these unscrupulous contractors are much more likely to make a sale.

When your newly installed panels don’t deliver as promised, you don’t have much recourse. It’s possible to take the contractor to court, but it’s usually not worth the hassle.

And many installers know this.

But when there’s a solar production guarantee involved, contractors are legally obligated to stand behind their promises.

Here’s how it works in practice:

How a solar production guarantee works

  • During the inspection and proposal process, the solar installers tell you what your system will generate once the panels are installed. You have that information in advance—before moving forward.
  • If your system doesn’t perform as promised, the installers are required to resolve the issue. Some solar production guarantees even include special “compensation” clauses. The PV contractor will pay you for any losses incurred as a result of poor system performance.

Do You Really Need a Solar Production Guarantee?

There is no law requiring that installers provide customers with production guarantees. But as a homeowner or business manager, you should absolutely insist on this type of protection.

However, be careful.

Some installers will try to use “soft” numbers based on ideal laboratory conditions—i.e. this is what your PV system could generate provided that your home meets certain criteria.

This is NOT a solar production guarantee.

You want transparent and customized wording specific to your property—not some laboratory on the other side of the world.
