The sun’s energy is constant, renewable, and never-ending. So is there a way to harness this energy and use it in our designs to make them more sustainable?
The answer is yes. Technology like Photovoltaic cells and thermal collectors are nowadays increasingly being used in modern architecture to create energy-efficient structures.
There are two main ways in which our sun’s energy can be utilized:
When sunlight hits the PV cells, it creates a flow of electrons that can be captured and used to power electrical devices. The electrical output from a solar panel depends on:
Solar panels are used on roofs, walls, and even facades to provide clean, renewable energy to buildings.
Solar panels can be integrated into building facades to provide clean, renewable energy while also improving the aesthetic appearance of the building.
Solar panels can also be used to provide shade for buildings, reducing the need for air conditioning and increasing the energy efficiency of the building.
Photovoltaic Thermal collectors or PVT collectors combine energy and heat generation and collection into one. It is more efficient than regular PVC modules.
This technology is similar to PVC cells. The additional advantage of thermal collectors is that they transfer the otherwise unused heat from the photovoltaic module to a heat transfer fluid to be used for thermal regulation.
The heat collected is then used for domestic water usage, heating of swimming pool water, water processing for industrial heating, agricultural drying, etc.
PV cells and collectors are used in a variety of ways to create sustainable and energy-efficient buildings. These technologies play an important role in reducing energy consumption, lowering energy bills, and minimizing the environmental impact of buildings.
