Bifacial panels can significantly increase energy production, and their market share is expected to grow rapidly.<\/strong><\/h3>\n<\/blockquote>\n

What are bifacial solar panels (double-sided solar modules)?
\n<\/strong><\/h3>\n

Traditional panels operate exclusively using their front side when exposed to sunlight. In contrast, bifacial solar panels generate and capture electricity from both surfaces, the front and the back. As a result, they can produce additional energy ranging from 5% to 90% compared to the energy generated by the front side alone.
Currently, bifacial panels have almost the same cost as their monofacial counterparts. A bifacial photovoltaic panel typically consists of 60 or 72 solar cells. These cells feature an identical metal grid on both the front and rear sides, with more than 95% of both surfaces available for light capture and, consequently, electricity generation.
Bifacial panels come in different designs. Some are framed, while others are frameless. Some use double glass on both the front and back sides, while others have a transparent back sheet. Overall, most bifacial panels use monocrystalline cells, although polycrystalline versions also exist.
According to the International Technology Roadmap for Photovoltaics, bifacial panels currently hold a 20% market share, with forecasts suggesting this could rise to 70% by 2030. <\/p>\n<\/div>\n

How it works<\/strong><\/h3>\n

It is important to clarify that the use of bifacial (BF) module technology does not increase the efficiency of the solar module itself, but rather the amount of solar energy collected per panel. By using bifacial solar panels, energy gains of up to 30% can be achieved, depending on factors such as the tilt angle, the reflectivity of the ground surface, the height above the ground, and many others.
The radiation collected by a panel consists of: <\/p>\n

    \n
  1. Direct radiation from the sun.<\/li>\n
  2. Indirect diffuse radiation caused by air particles, clouds, etc.<\/li>\n
  3. Reflected radiation from surfaces near the solar installation.<\/li>\n<\/ol>\n

    Diffuse radiation can contribute significantly to the total amount of radiation absorbed by a panel; however, a large portion of it will not be captured in a tilted or horizontally installed module. Tilting the module increases the intensity of direct radiation, but reduces a significant part of the indirect component.
    Indirect radiation has the same value regardless of its source. In contrast, reflected radiation depends on the nature of the surface surrounding the solar array, the tilt angle of the system, and other factors.
    The front side of the panel receives both direct and diffuse radiation, the amount of which depends on the tilt angle of the module. <\/p>\n

    The rear side of the panel receives light from two sources:<\/p>\n
