About QT Environmental

QT Environmental (M) Sdn. Bhd. is a Kuala Lumpur-based infrastructure company founded in 1991 as an expansion of QT Engineering and Consultancy. Its core expertise is designing, building and commissioning sewage treatment plants, with additional business lines in green asphalt (recycled-plastic road paving), solar panel installation, and mechanical and electrical services. Its leadership team includes engineers from chemical, civil and mechanical backgrounds, per its website.

The company says it has over 40 years of industry experience, though this may reflect its parent company's history rather than its own 1991 founding date. Its published project list names infrastructure clients including Sime Darby Property, IJM Construction, Genting Malaysia, Cyberview and several Malaysian government agencies, but every named case study on its website is a sewage treatment or pumping station project — none are solar installations.

QT Environmental's website describes solar panel installation only in general marketing terms, without naming panel or inverter brands, published warranty terms, project sizes, or the customer segments it serves for solar specifically. It doesn't mention financing or leasing options for solar.

Solar services offered by QT Environmental

Not mentioned on its website: battery storage, EV chargers, financing or leasing. Ask directly if you need any of these.

Before you get a quote from QT Environmental

• Ask for examples of completed solar installations — its published project case studies are all sewage treatment plant and infrastructure work, not solar.
• Ask about the specific panel and inverter brands it would use, since none are published.
• It says it was founded in 1991 but also claims "over 40 years" of industry experience — ask whether that figure includes its parent, QT Engineering and Consultancy.
• Confirm the application is under Solar ATAP, which replaced NEM 3.0 on 1 January 2026.
