The kingdom is long Cats, weather vans, and occasional sliding roofs are proliferating with solar panels. The roof of a house or business is a good place to be because the sunlight is rarely covered by the shadows and the roofs are generally unused – it is better to add panels to the existing structure than to clean the ground for a new farm.
But even panel-covered roofs are not used as efficiently as possible. A new field of science known as roof agrevoltars asks: ፡What if we were? as well as Did he grow crops under them? These are not ordinary green roofs, which are typically small gardens, but rather functional farms. Panels provide shade for plants – actually increasing their productivity – and for construction, at the same time reduce cooling costs and generate clean energy for construction. By 2050, the city’s population is expected to more than double. As people continue to migrate to major cities, Agrivotex on the roof will make it easier to feed people and make city life easier.
The roof is a very challenging place for plants to grow. There, a plant is subject to constant bombardment by wind and sunlight because there are no trees around it. (Accordingly, hardy plants are preferred for green roofs.) Yes, plants need light, but not so much. “Plants go to what we call photography mode, they can’t photosynthesize in a very bright and sunny place,” said Jennifer Bosselot, a horticulturist at the University of Colorado. “Instead of carbon dioxide, they start to take in oxygen and break it down, and they waste energy.”
Conversely, think of how a forest works: all plants, except tall trees, are getting some shade. For plants that are very close to the forest floor, the light is scattered, falling from the surrounding areas. If the tall trees around them had grown in the field, they would not have been exposed to the elements.
The idea of Agrivoltax is to duplicate this forest area for crops. In Colorado, scientists have been experimenting with agrovoltaic gardens and are finding that plants need to grow in the shade. This is probably a physiological response to the need to absorb a lot of light, and it is very good for leafy crops such as lettuce, because it increases their yield. Pepper plants also produce three times as much fruit as the sun in the agrovoltaic system. As a bonus, shady plants need about half the amount of water they produce because of the low sunlight.
The same concept applies to roofs: Solar panels provide shade that makes plants happier and less thirsty. Underneath the roof panels is found Buselot, cool in summer, warm in winter, and panels acting as windbreaks. The plants do not need to be food crops for the benefit of the environment – for example, adding agrovoltic plants to the attic provides local pollen. Scientists are playing with the design of semi-transparent solar panels, which in theory works better for species that need less sunlight in the open, but overall shade.
