SOLAR TREE
A solar tree is a device resembling a tree in shape, but with photovoltaic (PV) panels in place of its crown. The “leaves” of the tree capture solar energy and convert it to electricity, with branches funneling that electricity down through a trunk and into a central battery within. In essence, they provide the same benefits as solar panels, but they use only a fraction of the surface area necessary for an array of solar panels.
Solar trees are not a new invention, but they’re enjoying a rising popularity. As they exist today, more solar trees raise public awareness around sustainability than are used to generate residential or commercial power. What’s more, the trees are still perceived as “futuristic,” but it might be time we start shifting our mindset about these inventions by incorporating them into our vision of what sustainability looks like in practice.
BENEFITS OF SOLAR TREES
At first glance, solar trees might seem impractical — more art than function when compared to the best solar panels. But solar trees offer a few surprising benefits over their ground-mounted counterparts, including
SOLAR TREES PRESERVE LAND:
Since solar trees are vertically integrated, they require significantly less land than solar farms. The same logic would apply to a high-rise being able to fit more residents than a one-story house. Plus, because of their greater heights, the panels may receive more sunlight than a ground-mounted or roof-mounted arrangement would.
THEY CAN PROVIDE HABITAT FOR RARE FLORA AND FAUNA:
Solar trees are large enough to host tropical flowers, vines and plants on its trunk and branches. These valuable habitats provide homes for plants and animals, protecting biodiversity in urban areas.
SOLAR TREES REQUIRE LITTLE MAINTENANCE:
Besides cleaning debris off the solar panels every now and then, solar trees are standalone electrical units requiring little to no maintenance.
THE TREES COOL HEAT ISLANDS:
By creating shade in urban environments, solar trees reduce the amount of thermal energy that is reflected off of urban surfaces like asphalt, concrete and brick. This can combat the most deadly effects of climate change within cities.
THEY INCREASE AWARENESS OF CLEAN ENERGY:
The striking structures are immediate attention-getters, conveying a message of creativity, resourcefulness, humility and the need to incorporate sustainability into everyday life. We see similar art installations at work across the world.
