A 16-foot, metallic flower is now blossoming among the plants at the Detroit Zoo. This innovative ground-mounted solar panel system is called smartflower.
This high-tech addition is just another step on the Detroit Zoological Society’s (DZS) Green Journey to create a more sustainable future by using innovative practices that minimize our ecological footprint. It is the first of its kind to be installed not only in Michigan but in any zoo in the country.
Sunflowers turn their blossoms to face the sun to make optimum use of the light, increasing its growth rate. Since mother (nature) knows best, the creators of smartflower based the technology of this revolutionary system to function similarly to an actual sunflower, through the use of a GPS-based dual-axis tracker. The system features 12 solar panels – shaped to mimic petals – that follow the sun across the sky throughout the day. When the sun rises in the morning, the smartflower unfolds and aims its panels to the sky to begin producing energy. The petals will automatically close again when the sun goes down, storing the excess energy.
Since the smartflower is always at an optimal angle to the sun, it can generate 40 percent more energy than a traditional solar-panel system. The smartflower converts enough energy in one day to run an electric car for 62 miles, wash 17 loads of laundry or run three air conditioning units. The system at the Detroit Zoo is expected to generate more than 4,000 kilowatts of electricity annually, enough to power the Carousel and other areas of the Zoo.
The smartflower will be in full view during the DZS’s annual pre-Earth Day celebration called GreenFest at the Detroit Zoo on April 14, from 10 a.m. to 3 p.m.
The first 1,000 guests to visit the anaerobic digester educational display will receive a token for a 5-gallon bucket, courtesy of The Home Depot Foundation, to be filled with free Detroit Zoo Poo – an herbivore compost processed in the DZS’s anaerobic digester and produced in partnership with Detroit Dirt. The digester – the first in Michigan and the only zoo-based system of its kind – annually converts 400 tons of animal manure and other organic waste into a methane-rich gas that helps power the Ruth Roby Glancy Animal Health Complex.
The event will also include a sustainability tour as they learn about the DZS’s many green initiatives. Guests can learn about permeable pavement, composting, recycling, preventing bird strikes, making a home more energy efficient and building backyard wildlife habitats. They can also explore farm-to-table food options at Pure Greens Café, widen their science knowledge during chemistry demonstrations, and take a green pledge, committing to joining us on our Green Journey.
