New fastening systems for double-sided panels

The process of implementing bilateral modules is rapidly gaining momentum due to the growing need to generate more energy for less money, and the properties of bilateral elements are fully in line with this strategy. Despite the fact that at first their implementation after entering the market went at a relatively slow pace, leading companies in the field of solar energy have already realized the advantages of such panels.


Experts of Bloomberg New Energy Finance (BNEF) pay attention to the growth of interest of investors and EPC-companies in bilateral solutions, as a result of which a significant increase in the market of bilateral solar modules is expected in the coming years.

How double-sided solar cells work

Unlike single-sided, double-sided solar modules have glass on the back side instead of an opaque substrate, which transmits solar radiation to the photocells. Because of this, photocells “absorb” solar radiation not only from the front side, but also from the back side. Therefore, the height of such structures should ensure the unimpeded passage of reflected radiation.

Power is generated from both sides of the two-sided module, increasing total energy production by 5-30%. The maximum increase in energy production of 30%, on the other hand, is achieved when the solar panels are installed on a surface with a high ability to reflect solar radiation, for example, on the ground with light stones or on a concrete surface.

One of the conditions for the most effective operation of bifacial dual glass is the correct selection of mounting systems.

Features of fastening systems for double-sided panels

The two-sided principle of solar energy absorption determines that the higher the modules are installed, the greater the performance of the back side. Therefore, Solar Steel Construction engineers developed a special fastening system for SMS-212 bilateral panels, which consists of a table complete with hardware (for BIFACIAL modules). The main feature of the design is that there is no shading of the back side of the modules, the height from the edge of the panel to the ground is at least 1m to 1.2m. This is higher than the conventional design.

Note that the selection of equipment and technical calculation of solar power plants with bilateral solar modules has a number of significant features and subtleties. Therefore, we advise you to contact specialists for advice. We will quickly perform all the necessary engineering calculations, as well as provide EPC contracting services for the construction of a turnkey SPP.
