Sunguru Energy — Comprehensive 25-Year Warranty Overview

At Sunguru Energy, we believe every homeowner deserves long-term protection, transparency, and peace of mind. That’s why we stand behind every solar system we install with one of the strongest warranty packages in the renewable-energy industry.

Unlike other installers who offer limited protection or rely on soft estimates, we put every promise in writing and back it with real performance guarantees, certified installation, and long-term monitoring.

That’s why Sunguru Energy offers a true 25-Year Full System Warranty, including workmanship, product protection, microinverters, racking, roof penetrations, and guaranteed solar production
(depending on your state and program availability).

25-Year System Warranty

Your solar system is protected for 25 full years — covering defects, performance issues, and system failures.
We ensure long-term durability, safety, and reliable energy production.

25-Year Roof Penetration Warranty

We protect more than your energy — we protect your home.
Sunguru Energy provides a 25-year roof-penetration warranty, covering leaks or damage caused by the solar installation.
(Warranty duration may vary based on the solar program you apply for.)

25-Year Production Guarantee

We don’t just promise performance — we guarantee it.

If your solar system produces less than what we committed to in your contract due to an issue that is Sunguru Energy’s responsibility, we will:

• Reimburse you for lost production
• Fix the issue immediately
• Add panels if necessary

You are protected from lost energy value — something most installers do not offer.

We monitor your system for 25 years and respond to any performance issues fast and professionally.

25-Year Workmanship Warranty

Every system is installed by certified Sunguru Energy technicians and licensed electricians — never subcontractors.

Our workmanship warranty covers:

• All installation-related defects
• Electrical connection issues
• Long-term structural integrity
• A 10-year roof penetration guarantee (minimum)

If something was installed incorrectly, Sunguru Energy fixes it — no cost to you.
