Choosing the Right Solar Installer Matters
A solar panel system is a 25+ year investment. The installer you choose affects not just the upfront cost, but your system’s performance, warranty coverage, and long-term reliability. Here are 7 things to check before signing a contract.
1. SEDA Registration
Your installer must be registered with the Sustainable Energy Development Authority (SEDA) Malaysia. This is required for Solar ATAP applications and ensures the installer meets minimum technical standards. Ask for their SEDA registration number.
2. Tier-1 Panel Brands
Insist on Tier-1 solar panels from manufacturers like LONGi, JA Solar, Trina Solar, or Canadian Solar. These panels are tested for Malaysia’s tropical climate (high humidity, high temperatures) and come with 25-year performance warranties. Avoid unknown brands that may not honour warranty claims.
3. Inverter Quality
The inverter converts DC power from panels to AC power for your home. It’s the component most likely to fail. Look for established brands like Huawei, Growatt, SMA, or Fronius. Ask whether they offer string inverters or micro-inverters, and which suits your roof layout.
4. Workmanship Warranty
Panel manufacturers warranty the panels, but who warranties the installation work? A good installer offers 5–10 years of workmanship warranty covering wiring, mounting, and roof penetrations. This is separate from the panel warranty.
5. After-Sales Support
Ask about their maintenance packages, monitoring systems, and response time for issues. The best installers provide real-time monitoring apps so you can track your system’s output daily. Annual cleaning and inspection packages typically cost RM200–400.
6. Track Record in Perak
Ask for references from previous installations in Ipoh or Perak. A local installer understands the area’s weather patterns, common roof types, and TNB application process. Check Google reviews and ask to see photos of completed installations.
7. Transparent Pricing
Get a detailed quote that breaks down costs for panels, inverter, mounting, wiring, installation labour, and permits. Be wary of quotes that are significantly below market rate (RM3,000–4,000 per kWp) — they may be using substandard components or cutting corners on installation quality.
Don’t Rush the Decision
Take your time comparing at least 2–3 quotes. A good installer will happily answer your questions and provide references. If they pressure you to sign immediately, that’s a red flag.
