Solar Panel & Battery Storage Warranties

Comprehensive protection for your renewable energy investment through industry-leading manufacturer warranties plus Spectrum's 5-year installation guarantee and £1 million professional indemnity insurance.

Established in 2011, our experience across 10+ MW of installed solar capacity ensures you receive full warranty protection backed by tier-one manufacturers and our ongoing support throughout your system's lifetime.

5-Year Installation Warranty

Our labour warranty covers all physical installation work, protecting your property from any defects resulting from our workmanship.

£1M Professional Indemnity

Comprehensive insurance coverage for system design, ensuring any design-related issues are fully protected.

MCS Accredited Installation

Our installations meet Microgeneration Certification Scheme standards, ensuring warranty validity and full compliance.

Manufacturer Warranty Management

We coordinate all manufacturer warranty claims on your behalf, ensuring seamless resolution without hassle.

Understanding Your Solar System Warranties

Solar energy systems comprise multiple components, each protected by distinct warranties covering different aspects of performance and longevity. At Spectrum Energy Systems, your investment is protected through three layers of comprehensive coverage:

Spectrum Energy Systems Installation Warranty (5 Years)

Our labour warranty covers all physical installation work performed by our MCS-accredited engineers and NICEIC-certified electricians. This includes:

  • Roof Integrity: All roof penetrations, mounting systems, and weatherproofing. If we install components that subsequently cause property damage due to our workmanship (such as non-watertight tiles), this is fully covered.
  • Electrical Installation: All wiring, connections, consumer unit modifications, and electrical integration work.
  • System Design: Protected by our £1 million professional indemnity insurance. If anything we design proves defective or fails to perform as specified, you're covered.
  • Commissioning: System configuration, testing, and handover documentation.

Important Distinction: Equipment defects (faulty panels, inverters, batteries) are covered separately by manufacturer warranties detailed below. Our warranty covers the installation work itself, not product failures.

Two Warranty Types: What's Covered Where

Spectrum Installation Warranty (5 Years): Covers labour and workmanship. If our physical installation causes issues—leaking roof, faulty wiring we installed, mounting problems—we fix it at no cost.

Manufacturer Equipment Warranty (5-25 Years): Covers product defects. If a panel fails, an inverter stops working, or a battery develops faults, the manufacturer repairs or replaces it. We manage these claims for you.

Professional Indemnity Insurance (£1M): Covers system design issues. If we design a system that doesn't meet specifications or performs inadequately due to design flaws, this insurance provides protection.

Our Warranty Claim Process

Step 1: Contact Spectrum First
Report any system issues to our team via phone (0115 773 7575) or email ([email protected]). We assess whether concerns relate to installation work (our 5-year labour warranty) or equipment defects (manufacturer warranty).

Step 2: Initial Diagnosis
Our engineers determine the root cause through remote monitoring analysis or site visits. Many issues resolve through simple adjustments, system resets, or configuration changes without warranty claims.
