GreenTech Malaysia’s Green Energy Office (GEO), located in Bandar Baru Bangi, Selangor, is an outstanding example of a Building Integrated Photovoltaics (BPIV) system that is both functional and has aesthetic appeal. Completed in 2007, the building has a built-up area of 4,300 square meters and is designed to demonstrate different types of solar panel technologies.

On the rooftop is an array of poly-crystalline and amorphous-silicon panels that spans 456 square metres and has a combined capacity of 53 kWp. Mounted on top of the atrium and stretching over 110 square meters, is an array of mono-crystalline silicone panels with a capacity of 12 kWp. These panels are semi-transparent, letting daylight into the building and reducing the need for artificial lighting. An array of 200 square meters monocrystalline silicone panels with 27 kWp capacity is also installed over car park roof at the entrance.

In 2016, additional thin-film solar arrays were retrofitted over the building’s rear car park roof, and on a ground mounted structure at the field. The Solar PV system at GreenTech Malaysia is a grid connected system (no battery storage is needed) and provides a total capacity of 142 kWp. It generates an average of 468 kWh of clean, renewable energy daily and supplies up to 50% of the building’s total energy demand. The building’s solar features were duly recognised when it won the ASEAN Energy Award (RE Category) in 2009.
