Solar Installation in Malaysia: The Complete 2026 Guide
Thinking about installing solar panels at home? This guide covers everything Malaysian homeowners need to know — from costs and government programmes to choosing the right installer.
What Is Solar Installation?
Solar installation means fitting photovoltaic (PV) panels on your roof, connecting them to an inverter, and integrating the system with TNB's grid through net metering. During daylight hours, your panels generate electricity that powers your home directly. Any surplus energy is exported to the grid, earning you bill credits under Malaysia's Solar ATAP programme.
A complete residential installation includes the panels, inverter, mounting structure, cabling, monitoring system, and all permits. Your installer handles SEDA registration, the TNB application, and the bi-directional meter upgrade.
How Much Does Solar Installation Cost?
In 2026, residential solar in Malaysia typically costs RM 4,000–5,500 per kW installed. Common system sizes and price ranges:
- 4 kW (terrace house) — RM 16,000–22,000
- 6 kW (semi-D) — RM 24,000–33,000
- 8 kW (bungalow) — RM 32,000–44,000
Most homeowners see a payback period of 4–7 years and lifetime savings of RM 60,000– 120,000 over 25 years. Read our full 2026 cost breakdown →
Solar ATAP & Net Metering
Solar ATAP (Application for Approval by Distribution Licensee) is Malaysia's net metering programme run through TNB. It lets you sell excess solar energy back to the grid at the prevailing tariff rate, offsetting your electricity bill.
The 2026 quota is now open with unlimited capacity — there is no longer a waiting list for residential applications. Your installer submits the ATAP application on your behalf after you sign a contract. Solar ATAP 2026 guide →
