What are Bi-facial Solar Panels?
The energy sector is observing transition towards renewables, gaining much importance as the energy demands as well as the population are consistently increasing. Considering the Energy dependency as well as the dangerously increasing global warming and with the clear evidences that humans are changing the climate, call for actions are getting louder and alternatives are the only durable and clean sources to go with. Since, Solar energy is one of the most significant sustainable sources, PV technology dominates the renewable energy market. It can be considered as the “New king” of Energy sector. In this technological world, for renewable energy, the most crucial factor to be taken care of, is the overall system efficiency and one of the main factors for that potential if the total amount of solar
irradiance received. In order to receive the maximum irradiance and get the optimum yield out of the incoming
sunlight, a lot of researches have been conducted to bring advancement in technologies and play with all the
parameters responsible to increase the energy yield. Bi-Facial Solar Panels are one of those advanced
technologies.
How mono-facial and bi-facial are different?
A traditional mono-facial solar panel have an opaque back-sheet, whereas Bi-Facial Solar Panels have a reflective back or dual panes of glass holding the solar cells in place, exposing both sides to the sunlight, that makes it possible for more of the irradiance to be absorbed and generate the energy from both sides of the panel. Bi-Facial panels work like a mono-facial panels, the only difference is that the sunlight that gets through the glass and goes to loss, has a chance to get reabsorbed by-bi-facial panels and maximize the output.
Major Advantages of Bi-Facial Solar Panels
Increased Efficiency
As, Bi-facial panels can generate energy from both sides, it can increase the efficiency up to 30%.
More Durable
As Bi-facial panels are frameless and covered by tampered glass, they are more durable and have a longer life span.
Aesthetically Pleasing
Bi-Facial Solar Panels come in many different designs and that looks more pleasing aesthetically, than mono-facial solar panels.
Works better in diffused light
The availability of extra space in bi-facial panels also means that they perform well in diffused light, as well, making the long-term cost lower than mono-facial panels.
Reduced PID
In case of frameless bi-facial panels, solar cells are likely to be suffer less from the potential-induced degradation
Longer Warranties
Bi-Facial panels come with longer warranties up to 30 years.
Cutting it short, bifacial panels are versatile and they always present higher performance as compared to monofacial modules. Considering its advantages and the technological advancement, bifacial panels are the next big thing in the solar energy sector. Taking the current energy demand and supply into notice, and the mandatory energy transition towards renewable energy is inevitable and so is moving towards more advancement and efficiency, and in solar sector, bifacial solar panels are the way to go, while saving the space and optimizing the maximum efficiency, together.
