Ground-based PV structures with east-west orientation

The most popular, and, according to numerous studies, the most efficient, photovoltaic solutions are structures that allow the exposure of PV modules towards the south. This is mainly due to the amount of solar radiation that reaches the panels – the best results are generated when the rays fall perpendicular to the surface of the module. Nevertheless, when implementing the last project, the investor decided to use east-west systems – all in order to optimize the costs of building a photovoltaic power plant as much as possible.

Depending on the rated power of the installation, it is important to plan out the photovoltaic structures on the ground. A common implementation problem is the lack of space to accommodate the required number of PV modules. In the case of a farm built in the Greater Poland Voivodeship, the Energy5 project team proposed the use of classic hammered tables (with a module inclination angle of 8 °), but oriented towards the east and west. The introduced modifications will allow for a faster return to the project, which is the construction of a photovoltaic power plant, and for the fulfillment of all design assumptions. An additional advantage of the choice made by investors is the increased aerodynamics of the system, which is much less susceptible to the negative effects of the increasingly frequent, gusty winds.

The quality of Energy5 is confirmed by further certificates

The entire functioning of the company – quality management, occupational health and safety as well as environmental management – meets the highest world standards. The above-mentioned scopes of the company’s activities have successfully passed the DEKRA Certification process, which resulted in the confirmation of the implementation and performance of activities in accordance with the assumptions of ISO 9001: 2015, ISO 45001: 2018 and ISO 14001: 2015.
