Solar Warranty Explained: What's Actually Covered (And What Isn't)

Solar Warranty Explained: Know What You’re Protected By

If you’re considering solar, you’ve probably heard confusing warranty terms: “25-year performance warranty,” “10-year inverter warranty,” “5-year labor warranty.” What does it all mean? What actually happens if something breaks?

Let’s clarify.

The Three-Layer Warranty System

Most solar systems have THREE separate warranties. You need to understand all three.

1. Solar Panel Warranty: 25 Years

What’s Covered:

• Manufacturing defects in the panel structure
• Wire failures or solder defects
• Delamination or seal failures
• Performance guarantee: Panels maintain at least 80% of rated output after 25 years

What’s NOT Covered:

• Damage from extreme weather (hail, lightning, storms)
• Damage from improper installation (this is why professional installers matter)
• Normal wear and tear
• Damage from user neglect

Real Example: Your 25-year-old panel degrades to 75% output (below 80% guarantee). The manufacturer replaces it at no cost—you just pay shipping. This rarely happens; most panels last 30-40 years.

2. Inverter Warranty: 10 Years (Standard)

What’s Covered:

• Manufacturing defects in components
• Power conversion failures
• Control system issues
• Labor: Repair or replacement at no cost

What’s NOT Covered:

• Damage from power surges (unless caused by installer error)
• Wear from extreme heat or cold
• Improper maintenance

Why This Matters: The inverter is the “brain” of your system. It converts DC power from panels to AC power for your home. A failed inverter means no power. Most last 10-15 years, but replacement parts are usually cheaper than you’d think ($500-$2,000).

Extended Warranty Available: We offer 15-year extended inverter warranties for about $500-$800. This gives peace of mind if you plan to keep the system 25+ years.

3. Our Labor & Installation Warranty: 5 Years

What’s Covered:

• Faulty electrical connections or wiring installed by us
• Improper panel mounting or alignment
• Switchboard or battery installation issues
• Safety switch failures due to our work
• Cable management or code violations caused by installation

How Claims Work: If you discover an issue related to our installation, we repair it at no cost within 5 years. For example:

• Loose panel connection → we re-secure and retest (free)
• Faulty breaker we installed → we replace (free)
• Wiring issue in our conduit → we fix (free)

What’s NOT Covered:

• Component failure (that’s covered by manufacturer)
• Damage from you or someone else modifying the system
• Storm or extreme weather damage
• Normal wear and tear

What Typically Fails? (And What Doesn’t)

Rarely Fails:

• Solar panels (~0.1% failure rate in first 5 years)
• Wiring and electrical connections (when installed properly)

Occasionally Fails:

• Inverters (3-5% require service within 10 years)
• Safety switches (normal wear after 10+ years)

Never Fails:

• Modern mounting systems
• Properly installed electrical boxes

Insight: Quality installation dramatically improves warranty outcomes. This is why professional SAA-accredited installers matter.

Real Warranty Scenarios

Scenario 1: Inverter Stops Working (Year 4)

• Inverter fails after 4 years
• Covered under 10-year inverter warranty
• Manufacturer or our team replaces it free
• Takes 3-5 days typically
• Cost to you: $0
• System downtime: Minor (you’re grid-connected, so you have backup power)

Scenario 2: Panel Degradation Beyond Guarantee (Year 23)

• Panel tests at 76% output (below 80% guarantee)
• Covered under 25-year panel performance warranty
• Manufacturer replaces panel
• Takes 1-2 weeks for shipping/install
• Cost to you: $0 (except shipping if you opt not to wait)
• System continues functioning (1 panel out of 20 doesn’t dramatically reduce output)

Scenario 3: Storm Damage to Roof (Year 2)

• Hail damages one panel
• Is this covered? NO—storm damage isn’t covered by solar warranty
• What’s your recourse? Claim through homeowner’s insurance instead
• This is why we recommend adding solar systems to your home insurance policy

Scenario 4: Faulty Wiring We Installed (Year 3)

• Electrical arcing discovered in conduit installed by us
• Covered under our 5-year labor warranty

Common Warranty Questions

Q: Can I transfer warranty if I sell my home? A: Yes. Most manufacturer warranties and our labor warranty transfer to the new owner. This increases your home’s resale value.

Q: What if the installer goes out of business? A: Our labor warranty is honored by our business. Additionally, most components have direct manufacturer warranties (panel, inverter) that aren’t dependent on installer longevity.

Q: Does warranty cover maintenance? A: Warranty covers failures and defects, not preventative maintenance. We recommend annual system checks (~$150) to catch issues early.

Q: If my system performance drops, is it covered? A: Depends on the cause. Performance drops from panel degradation? Covered under 25-year guarantee (if below 80%). Performance drops from inverter issues? Covered under inverter warranty. Performance drops from dirt/shading? Not covered (this is maintenance).

Q: Do I need a separate home insurance policy update? A: We recommend adding your solar system to your home insurance (usually costs $50-$100/year more). This covers storm damage, theft, etc. that solar product warranties don’t.

The Bottom Line on Warranties

• Panels: Virtually never fail (25-year guarantee for peace of mind)
• Inverters: Occasionally need service (10-year warranty typical; extended available)
• Our Installation: We stand behind our work (5-year labor warranty)
• Your Responsibility: Maintain your system and claim home insurance for weather damage

The best warranty? Hiring a professional installer with a track record of quality work. That’s us.
