Two-Sided Solar Panels and Their Increased Efficacy
Now it is more feasible to enhance energy accumulation with the help of two-sided solar panels which can be placed towards the sun’s direction. These panels rotate with changing the course of the sun and are more efficient in energy collection from the sun. Before, solar panels were used with their one side, which was utilized to allocate solar energy. But the power collected by one-sided solar panels was relatively low, and scientists discovered the new formula of enhancing energy assemblage by innovating double-sided solar panels in the market. Scientists have succeeded in combining the effects of both solar panels to extract the maximum amount of solar power from sun radiations.
Singapore research institution and its findings
The researcher of Solar Energy Research Institute of Singapore Carlos Rodriguez and his fellow workers discovered that the energy cost of electricity is reduced by 16 % with the help of double-sided solar panels. Moreover, two-sided solar panels that follow sun direction can extract 35 % more energy than ordinary solar panel that is plus point for solar power producing industries. He described that a solar panel aims to attain maximum power from sun radiations. Still, nowadays usual solar panel is fixed in one place as their one side is taking solar radiation. Hence they can produce solar energy from only one side, and the amount is comparatively low, and the cost is high for these kinds of panels. Rodriguez-Gallegos also narrates that the most significant possible benefit we can obtain from double-sided solar panels is that they can absorb the energy reflected from the earth onto their backside besides absorbing light form sun.
Comparison between nonofficial and bifacial panels
There are two kinds of solar radiation extracting solar panels present in markets. The first is a single-axis panel which rotates from east to west to maintain its side towards the sun for the whole day. The second is the double-axis, these also track the sun throughout the year but alter their directions according to seasons because the sun is on the equator in the summer season, but in winter it is more tilted towards poles.
The scientists of Singapore research institute analyzed the total amount of global energy that is produced with the assistance of a combination of different types of solar panels in one year. Furthermore, they evaluated all records of global weather that they took form NASA rotating clouds and also analyzed the Earth’s Radiant system of energy device. And then they finally calculated the total energy produced by different combined or isolated solar panels. They reached one conclusion that when double-sided solar panels are associated with single-axis solar panel, they will create 35% more solar energy. Still, when they use the double-sided board to combine it with double axis panel they found that energy production was increased by 5 % it means double-sided and dual-axis solar panels collectively can produce 40% more energy. Besides, analysis of expenses for producing solar energy they also took calculations of costs of devices, materials, and maintenance and manufacturing expenses with different rates in all regions. With the help of double-sided and single-axis solar panels, the expenditures of energy production can be reduced by 15 to 16 % as experimented by most of energy experts. Levelised cost of energy (customer cost per kilowatt-hour of solar electricity he received) is decreased with the innovation of two-sided panel, which will help us to take maximum advantage of solar energy in the near future.
Improved and better Locations of solar panels
The double-sided solar panels can be positioned vertically on top of roofs or can be fixed horizontally unlike the single-faced panels which have complications in their location on houses or industries. The surface made of grass, sand, concrete and tile is still in the testing phase to calculate the maximum amount of energy which is reflected from these surfaces towards the rear of bifacial solar panels. It will help to evaluate the total quantity of energy produced by two-sided solar panels when placed or positioned on these kinds of surfaces.
How we can implement this new technology for producing more energy
It seems excellent and straightforward formula of increasing energy production, but this requires a year of research and designing to implement this new technology worldwide. It will benefit power industries to invest more amounts in these kinds of solar cells. And these industries will conduct their research on the creation of more advanced solar panels for future generations which would revolutionize the power industries with bringing substantial profit margins. The professor, Ashraf Alam of Purdue University, said that there were single-faced panels which absorb solar energy from the sun but with lower quantity and higher cost because these cells took more than 50 years to show improvement in their designs and efficacy. Although they are excellent for power generation from the sun, but we are unable to enhance their power absorbing capabilities, and we cannot reduce their expenses. However, we have got new technology or formula with two-faced solar panel technology which we will use to boost energy production with minimum possible costs. The scientists are working on designing panels for placing on glass windows of buildings and farmlands of countryside areas. But the problem of sunlight stoppage by these panels for crops is resolved by creating transparent bifacial solar panels that would not stop sunlight for vegetables or plants while absorbing sun radiation at farmlands.
Other benefits
Moreover, the innovation of two-sided windows based panels will help people to utilize more renewable power. The design of these panels is upgraded by increasing the number of space between semiconductors in panels that are called junctions which allow movement of electricity. Two-faced panels with single terminals offer biggest energy gain as compared to separate faced panels with minimum space between junctions. The relative benefit is not so significant as compared to absolute gain, which is increased by boundaries of intersections. With manipulation of junctions, these might get low relative gain but will surely get higher total benefit.
Researchers have given the formula to power industries which is going to be implemented soon for manufacturing of bifacial panels.
