Ensure that the fixing structures resist the elements and remain secure on the roof. This is the objective of Solar Group, which, since 2015, has been testing the resistance of its materials with a turbine that simulates the effects of wind on equipment.
During the testing, carried out at the IAE (Institute of Aeronautics and Space), located at the DCTA (Department of Aerospace Science and Technology), the wind speed is controlled, complying with Brazilian regulations NBR 6123, which deals with wind strength in Brazil.
According to the company, the structures are tested to withstand air gusts of up to 180 km per hour. “We place great value on the quality and durability of our products”, emphasized Ronaldo Koloszuk, commercial director at Solar Group.
“The photovoltaic system is designed to last more than 25 years, and the structures should last longer than that. There are reports of systems operating in Europe for almost 40 years. So, the use of suitable materials – in the case of Solar Group, which always opts for top-of-the-line equipment such as 304 stainless steel and aluminum, for example – makes all the difference in the durability of the structures over time”, highlighted the specialist.
Therefore, for him, testing these products in laboratories is very important to ensure this safety. “For this reason, since 2015 we have been carrying out resistance tests in tunnels to ensure that the structures can withstand the winds in Brazil. We even look for the best laboratories. The one we use is also used by Embraer in its tests”, he highlighted.
Solar Group reaches 1 GW of structures
The company reached 1 GW sold in structures for distributed generation on roofs and slabs throughout the Brazilian territory. At an accelerated pace of growth, the manufacturer saw an increase of approximately 140% in turnover in the country in the first six months of this year, compared to the same period last year.
In order to meet the growth in orders, Solar Group opened its second manufacturing unit, located in the city of Santana do Parnaíba (SP), with investments of around R$ 19 million.
“Achieving the first GW in distributed solar generation structures is, at the same time, a source of great pride and reflects the process of 'tropicalization' of the technology and products that we developed based on the best photovoltaic projects around the world”, highlighted the executive.
