The best warranty isn't about a single number — it's about coverage across every component, put in writing. Tripower provides a 10-year workmanship warranty, panels with a 25-year performance warranty (80% output guaranteed) plus a 12-year product warranty, inverters covered 5-10 years depending on brand, batteries 3-5 years depending on type, a 10-year anti-corrosion warranty on mounting structures, and a 3-year warranty on monitoring systems.
Why Warranty Length Alone Is Misleading
A company advertising "25-year warranty" without specifying which component it covers can be misleading — panels, inverters, batteries, mounting structures and workmanship all degrade and fail differently, and each typically has its own separate warranty term. When comparing companies, ask for a component-by-component breakdown rather than a single headline number.
What a Complete Warranty Package Should Cover
- Workmanship — covers installation quality and defects from the install itself, distinct from component defects.
- Panels — a 25-year performance warranty with an 80% output guarantee is the current industry standard for Tier-1 monocrystalline panels, plus a separate product warranty (typically 10-12 years) covering manufacturing defects.
- Inverter — usually the shortest-lived major component; 5-10 years depending on brand.
- Battery — 3-5 years depending on chemistry and usage.
- Mounting structure — anti-corrosion coverage, important given dusty and humid conditions in this region.
- Repair work — any post-installation repair should carry its own warranty, typically around 6 months.
Warranty Is Only as Good as the Company Behind It
A long warranty term is only useful if the company is still operating, has a local service network, and responds when you call. Check how long the company has been established, whether they're NEPRA certified and IESCO-approved, and whether they offer ongoing maintenance like an Annual Maintenance Contract rather than disappearing after installation.

Tripower has been established since 2014, completed 500+ installations across Islamabad and Rawalpindi, and is NEPRA certified, IESCO-approved and ISO 9001:2015 certified. Get your warranty terms in writing before you commit.
Frequently Asked Questions
What happens if the inverter warranty and panel warranty differ?
This is normal — inverters typically carry shorter warranties (5-10 years) than panels (up to 25 years for performance) because they're electronic components that wear differently. A reputable company will document each separately.
Is a longer warranty always better?
Not if it isn't backed by a company likely to still be operating, or isn't clearly itemised by component. A shorter but clearly documented, honoured warranty is more valuable than a vague long one.
Does an Annual Maintenance Contract affect my warranty?
Regular maintenance, such as Tripower's Bronze, Silver or Gold AMC tiers, helps keep your system performing within warranty expectations and often surfaces issues before they void coverage.
