7 Warranty Facts Every Solar Owner Needs to Know

Solar warranties protect your investment, but not all coverage is the same. Here’s what every homeowner should understand:

1. There Are Multiple Warranties

You may have separate warranties for panels, inverters, racking, and workmanship. A qualified service professional can take advantage of these warranties for you and provide replacement components at no extra charge.

2. Panel Warranties Often Last 25 Years

Most cover production guarantees, ensuring your panels generate a certain percentage of their rated output over time. Panels are quite robust, which means manufacturers are comfortable warrantying them for almost 30 years.

3. Inverter Coverage Is Usually Shorter

Inverters often have 10–15 year warranties—sometimes extendable for an added cost.

4. Workmanship Coverage Varies

At SLM Solar, we offer a 5-year workmanship warranty on all service labor. Many companies offer as little as 1-year or do not offer a warranty at all.

5. Warranties Don’t Cover Everything

Damage from storms, pests, or homeowner modifications or work performed by unlicensed/uncertified contractors may not be included.

6. Transfer Rules Matter

If you sell your home, some warranties transfer automatically; others require paperwork.

7. Keep All Documentation

A warranty is only as good as your ability to prove coverage. Keep digital and physical copies of all warranty paperwork for your records.

Understanding your coverage means no surprises down the road.
