Thank you to all of our supporters!
You helped us raise over $7,300 during April to support improvements to our partner's workshops and secure a spot for STG on GlobalGiving. Read more about the project here (first report available July 2013).

Our Organization

STG (previously operating as the Solar Turbine Group) is a 501(c)(3) non-profit organization based in Cambridge, Massachusetts whose mission is to provide technical, financial and intellectual support, assistance, and training to projects and organizations focused on bringing sustainable energy technologies to communities across the developing world.


Our Vision

Access to an affordable, distributed, renewable form of energy generation can improve productivity and quality of life in rural villages, clinics, schools, and organizations without increasing their carbon footprints. The development of a solar technology that can be locally customized, manufactured, and distributed will promote local economies while extending energy access beyond the traditional electricity grid.


Our Approach

We aim to help doctors and nurses in rural villages provide improved care to their patients - lights for extended hours, power for improved tools and medical records - affordably, renewably, and with benefits to the local economy. To meet this goal, we have developed a novel solar energy technology that is sized to provide electricity and hot water to off-grid clinics and schools and which can be completely manufactured locally. Since 2005 we have been working with local, regional, and international partners to develop and test this technology in the field in Lesotho, southern Africa. At the same time, technology training for local partners has led to a staff capable of undertaking local manufacturable at a cost competitive with PV panels. We are currently finishing construction and validation of our first user-test installation at the Matjotjo Village Health Clinic in the Berea District of Lesotho, starting a new technology training program for 2013, and helping partners scale manufacturing for their first commercial sales - deliverable late 2013.
