Solar Panel Warranty Malaysia: Product vs Performance Warranty

A solar proposal should separate product warranty, performance warranty, inverter warranty, mounting warranty and workmanship coverage.

Warranty language can be confusing because different components have different coverage periods and claim conditions. Read the actual terms before comparing brands or installers.

The Main Warranty Types

A product warranty covers manufacturing defects under the manufacturer’s terms. A performance warranty relates to expected module output over time. Inverter, mounting structure and workmanship may have separate terms.

What the Owner Should Confirm

• Who is the warranty provider?
• How is a claim submitted from Malaysia?
• What labour, transport or removal costs are included?
• Are monitoring, maintenance and weather damage treated differently?
• What documents are needed to keep coverage valid?

Warranty Is Not the Same as Maintenance

A warranty may cover a defect but not routine cleaning, damage caused by external events or system changes. The quotation should explain maintenance responsibilities separately.

Frequently Asked Questions

Does a longer warranty always mean a better panel?

Not necessarily. Compare the manufacturer, local support, claim process, exclusions and the quality of the installation.

Who should keep the warranty documents?

The property owner should keep invoices, commissioning records, serial numbers and warranty documents in one place.
