Soltec, leading Spanish company in the manufacture, supply and installation of single-axis solar trackers, presented the optimised version of its SF7 Bifacial tracker at Genera 2020, Madrid’s International Energy and Environment trade fair. This tracker, which is able to harvest energy from both the front and rear sides of the module, achieves a production increase of up to 16%.
One of the mainstays of Soltec is its R&D team and the constant implementation and renovation of its products. This ensures that the company always offers its clients the best possible option that allows them to achieve improved cost effectiveness and a greater return on their investment whatever the project. Since it was founded in 2004, this Spanish company has significantly increased its sales year on year, to position itself as one of the companies with the largest market share in the PV sector. Currently, this Murcia-based company is a leader in Latin American countries such as Brazil, in addition to having a major influence on the Chilean and Mexican markets, according to the solar PV market study by Wood Mackenzie.
The SF7 Bifacial tracker from Soltec has also consolidated the company’s position in the solar power market, thanks to its robust structure and easy assembly, which is able to optimise plant installation time. The tracking equipment has been designed as a solid structure that helps to create an even greater return on clients’ investment and ensure that the PV plants have a high level of performance. In addition, the Soltec trackers are self-powering, meaning that they require no additional PV modules or grid connection to start working during their installation.
Thanks to its capacity to obtain energy not only from the front side but also from the rear, the SF7 Bifacial achieves an energy generation of between 7% and 16% more, compared to its monofacial counterpart. This variation essentially depends on the albedo, although it is also affected by other variables such as module height and the distance between panels.
To analyse all these parameters and achieve daily improvements to the processes and operation of the SF7 Bifacial tracker, Soltec inaugurated the Bifacial Tracker Evaluation Center – BiTEC in 2018, based in Livermore (California, US). The aim of BiTEC is to investigate all the variables that impact on the performance of bifacial equipment and ways to improve output to achieve a greater return on investment. This centre researches aspects such as assembly height, the clarity and characteristics of the ground, module temperature and other features that impact on energy generation and optimise the performance of the bifacial structures.
In addition to manufacturing single-axis solar trackers, Soltec is dedicated to the supply and installation of these assemblies to utility-scale projects worldwide. To date, the Spanish company has supplied more than 270,000 of its solar trackers around the globe. The company currently has projects spanning the globe with factories in Spain and Brazil as well as subsidiaries on the five continents.
