Solar panel installation covers a lot more than bolting panels to a roof. A proper job includes a site survey to check roof orientation, shading and structural load, system design and sizing against your electricity bill, inverter selection, wiring back to your distribution board, coordination with TNB for grid connection under NEM (Net Energy Metering), and the paperwork that goes with it. In Petaling Jaya, most residential and commercial jobs are grid-tied systems, so the installer also needs to handle the net metering application and final inspection sign-off, not just the physical mounting.
We list 10 solar panel installers covering Petaling Jaya. Before picking one, check that they hold the relevant electrical and solar competency registrations, ask how many years they have been doing grid-tied installs (not just off-grid or small DIY kits), and get a written breakdown of panel brand, inverter brand and warranty terms for both. Warranty matters more than most other line items here: panels are typically rated for 20-25 years and inverters for 5-12 years, so a installer who disappears after year two leaves you exposed if something fails.
Our scoring weighs review patterns, responsiveness, and consistency of work over time rather than a single standout job. For a side-by-side comparison of all installers in this category, see the ranked guide to electricians in Petaling Jaya. If you want to understand exactly how we build that ranking, read our methodology.
