Qatar Solar Technologies (QSTec) presented Barwa with the first of 136 solar modules that will be used to power Qatar's Passivhaus-Baytna project.
When installed, the SolarWorld-QSTec photovoltaic monocrystalline silicon panels will provide all of Passivhaus' electricity requirements, with excess power being exported back into Kahramaa's power grid.
Dr Khalid K. Al Hajri, QSTec chairman and CEO, said: "QSTec aims to bring solar into the mainstream of Qatar's energy mix. Solar is recognised as Qatar's primary renewable energy technology and an essential part of our sustainable energy future."
He added: "Barwa's Passivhaus-Baytna project will demonstrate that, by using solar and environmental technologies, you can build quality homes and buildings, complete with all the latest modern conveniences, while substantially reducing our carbon footprint and protecting the environment for future generations."
The QSTec-supplied high efficiency panels have an installed power of 34 kilowatt peak and will produce around 58,000 kilowatt hours of electricity per year. Using this solar power system to supply Barwa's Passivhaus will help avoid approximately 35 metric tons of CO2 emissions per year.
The Passivhaus-Baytna project will have two identical 225m2 villas built side-by-side in Barwa City to compare the energy use and environmental footprint of each dwelling.
A regular villa is being constructed to a one-star Global Sustainability Assessment System (GSAS) standard while the Passivhaus villa, with all the comforts of a modern home, will consume 50% less energy and water, resulting in a halving of carbon footprint. The villas will be ready for occupation later this year.
"QSTec and its partners are leading the way in providing high quality solar solutions to Qatar and the region and we are proud to be a part of this ground-breaking project," Dr Al Hajri added.
