Bifacial solar, with its exclusive advantages over conventional solar panels, could be the next big thing in the solar energy secto
FREMONT, CA: The quest for improving the efficiency of solar panels has resulted in numerous innovations over the years. The bifacial solar panel that allows light to pass from both sides of the panel is one such innovation that is now readying itself for commercial adoption. Many properties of these double-sided panels are better than the conventional solar panels that are currently in use. This has led to an increasing focus on advancing the bifacial panels and preparing them for the market. However, one limitation that has delayed the adoption is that of affordability. The fact that the installation of bifacial panels entails a costly procedure results in the high prices. Nevertheless, recent developments signal that in a few years, bifacial panels might take over.
Bifacial solar panels can produce electricity from direct, as well as reflected sunlight. The absence of opaque backsheets allows sunlight to penetrate the glass panels and then reflect back again. In addition, bifacial panels can be arranged in arrays different from typical arrays. Traditionally, solar panels are installed in a south-facing manner owing to the ideal outputs. With bifacial panels, the installation can be in the east to west direction as well. The fact that both sides of these panels have the ability to generate electricity enables two peak production periods-once when the sunrays fall on the first face during the first half after sunrise and the next when the sun begins setting towards the west. This kind of optimal positioning is not possible with conventional panels.
The physical properties of the glass-based bifacial solar panels are relatively better than the solar panels in common usage today. Manufacturers currently guarantee a lifespan of 30 years for bifacial panels, which is more than what is guaranteed for conventional panels. Besides, the bifacial panels are better at resisting corrosion and cracking.
Renowned market players are putting their money into bifacial solar panels due to which it is fair to expect that in a few years, the efficient panels might see wide commercial adoption.
