Warranty Policy

Last updated: September 2026

Every inverter, lithium battery and solar panel that LEMAR SunTech supplies and installs is backed by a 5-year LEMAR service warranty, on top of whatever warranty the manufacturer itself provides (many solar panels, for example, carry a manufacturer warranty of 25 years or more — this is stated on that panel's product page).

What Our 5-Year Service Warranty Covers

• Workmanship — any issue caused by how the system was installed, wired or commissioned by our team.
• Manufacturer defects — if a product itself is faulty, we manage the manufacturer's warranty claim on your behalf, so you never have to deal with the factory directly.

What's Not Covered

Like any equipment warranty, ours doesn't cover:

• Damage from misuse, unauthorized modification, or repair attempted by someone other than our team.
• Damage from external events — fire, flood, physical impact, or electrical surges unrelated to our installation work.
• Normal, expected wear — for example, a lithium battery's capacity gradually declining after thousands of charge cycles over many years is expected behavior, not a defect.

How to Make a Warranty Claim

1. Message us on WhatsApp with your name, installation address, and a description of the issue.
2. Have your invoice or proof of installation ready if possible — it helps us confirm the warranty period.
3. Our team will assess the issue, and either resolve it directly or coordinate a manufacturer warranty claim for you.

Manufacturer Warranties

Some products — solar panels in particular — carry their own, separate manufacturer warranty that is often longer than our 5-year service warranty. That manufacturer warranty is governed by the manufacturer's own terms; we simply act as your point of contact so you don't have to deal with the factory yourself.
