It’s a lot like buying durian to find the best solar company in Malaysia: if you choose the wrong one, you could regret it for a long time. It’s not only smart to look into a company’s credentials if you genuinely want to go solar; it’s absolutely necessary. This is how to identify the difference between folks who are qualified and trustworthy and curry-puff sellers who are just trying to sell you panels quickly.

First, licenses are quite necessary. “SEDA” and “Suruhanjaya Tenaga” are the two words that will help you. SEDA Malaysia (Sustainable Energy Development Authority) has a list of all the solar PV service firms that are registered on its website. A big red flag is if you can’t find a solar installation or firm in that database. The Energy Commission Malaysia, also known as Suruhanjaya Tenaga, makes guidelines for safety and technical expertise. You can either ask for copies of both licenses or look them up online like a detective who has had too much coffee.

Now let’s discuss about those reviews. Don’t merely skip over the one-star complaints or the five-star reviews. Facebook, Google Reviews, and Lowyat.net are all good locations to find honest reviews. Did customers rave about how quickly they got support, or did they grumble about how long it took to acquire their warranties? Watch out for the juicy bits, like stories about jobs well done or terrifying stories about roofs that leak or installers who go missing. If you observe a lot of reviews that are the same and have been copied and pasted, something is amiss.

You should also ask about the hardware. Companies that are honest work with well-known companies including JinkoSolar, LONGi, Huawei, and Sungrow. Get datasheets from the maker that have the letters “TUV,” “CE,” or “IEC” on them. These letters mean that the panels and inverters are not just inexpensive objects you may find online.

Finally, a phone call or a visit in person might help a lot. Do the staff members answer your questions with confidence and without using too much technical language? Is the office and showroom real, or is it just a WhatsApp number and a vague address in Cheras?

Don’t hurry; ask, check, then check again. You should only engage with a true, trustworthy solar partner for your roof and your retirement savings. If you do some work now, you might be able to avoid a problem that costs a lot of money later. Plus, you’ll sleep better when the panels start to soak up the sun.
