About Principal Engineering
Principal Engineering Sdn Bhd is based in Klang, Selangor. It says its mission is to promote sustainable energy through cost-effective solutions and smart energy systems for residential, commercial and industrial customers, drawing on what it describes as more than 10 years of expertise in solar and energy-saving solutions and more than 40 years of experience in civil engineering.
The company says it has completed more than 100 top-quality installations throughout Malaysia, though it doesn't name specific projects, clients or system sizes. Its website lists 'Registered Service Provider,' 'G3 Registered Contractor,' and 'Corporate Member' as credentials, without naming the certifying bodies for the first and third.
Principal Engineering offers solar solutions for homeowners, businesses and off-grid applications such as islands, rural villages and resorts. Its website names solar technology partners only generically, as 'Our Technology Partners,' without listing specific brands, and it doesn't publish warranty terms or financing options. Enquiries go through phone or email.
