Energy….Using the Sun
Sustainability must include renewable energy. The Koi ponds require electricity to circulate water to and from the filters. Electricity runs the pumps for the waterfalls, circulates the nitrate rich used filter water to the gardens. Electricity is necessary for the UV lights which kill unwanted bacteria and algae in the water. One cannot begin to list the reasons electricity is necessary for a 65oo sq ft house!
These solar photovoltaic dual-axis solar trackers contain 12 panels each. Dual axis means they swivel and rotate up and down fro east to west, always pointing at 90 degrees to the sun, getting 40% more production than stationary panels. On a sunn6y day, they can produce 100kws, which is monitored in real time by an onsite and remote monitoring system.
Heat is always a consideration in sustainability, especially in Colorado. Ten roof mounted panels each consisting of a series of double evacuated tubes, convert solar energy into heat. This heat is stored in a 700 gal tank waiting to be distributed to the ponds, the rooms of the house by radiant heat, domestic water, and even the hot-tub.
The next project will be incorporating Geothermal heating for our future greenhouses.
