Is this where is all started?
The Drake Landing Solar Community is the first solar powered community of North America. Located in the town of Okotoks, Alberta, Canada, the project sets a wonderful example of how every household can lead a sustainable lifestyle. There are 800 solar panels located throughout the community on garage roofs, and they produce 1.5 mega-watts of thermal power during a summer day and supply heat to the district heating system. The whole system meets 90% of the annual heating and hot water needs of the homes.
The 52-home solar community has installed an array of solar panels on the roofs of their houses and garages. Glycol solution runs through an insulated piping system, or collector loop, that connects the array of solar panels. The solar panels absorb the solar energy during the daytime and heat the glycol solution. The glycol solution travels through the collector loop and reaches an underground heat exchanger within the community’s centralized Energy Center. The heat is then transferred from heat exchanger to the water stored in a short-term storage tank. The glycol solution returns to the solar collector system. The Energy Center has short-term thermal storage tanks and long-thermal storage tanks (Borehole Thermal Energy Storage (BTES) system).
