Brazil is consolidating itself as one of the world’s major solar markets. According to Solar Power Europe information released by Exame, the country currently ranks fourth globally, behind only China, the United States and India. In 2024, 18.9 GW of peak PV capacity will be added, strengthening the strategic role of the renewable source in the national electricity matrix.
Data from the Brazilian Solar Photovoltaic Association (Absolar), shared by Agência Brasil, show that solar power generation has already exceeded 55 GW of installed operational capacity, equivalent to 22.2% of the country’s electrical capacity. This expansion has prevented the emission of approximately 66.6 million tons of carbon dioxide during electricity generation.
In this scenario, specialized maintenance of equipment targeting this sector gains importance. Bruno Bueno, CEO of Ozora Soluções, which specializes in the maintenance and repair of solar inverters, explains that solar inverters are considered the “brain” of photovoltaic systems, responsible for converting energy into usable alternating current.
Frequency converters play a major role in industrial modernization, allowing precise control of the speed and torque of electric motors. “Solar inverters are vital for the energy transition, while frequency inverters optimize energy consumption in industries, adapting them to real demand,” he explains.
It highlights that the energy efficiency of the system is directly dependent on the health of this equipment and that adequate maintenance can ensure maximum performance and reliability. “When maintenance is neglected, the inverter can operate at reduced efficiency due to deteriorating components or overheating, resulting in lost power generation or wasted consumption due to inaccurate control,” he adds.
“Regular care ensures that equipment performs within project specifications, protecting the investment and increasing energy and financial return,” the executive adds.
Among the most common problems identified by Ozora is excessive heat caused by the buildup of dirt and dust in the air filters and heat sinks. According to Bueno, this excessive temperature can accelerate the degradation of important components, such as IGBTs and capacitors. “The absence of inspection can lead to missed electrical connections, which generate hot spots, or firmware failures that affect the inverter’s performance and communications,” he explains.
For the professional, preventive maintenance, performed at regular intervals, is an essential strategy for extending the useful life of equipment. “This includes technical cleaning, reconnecting of peripherals and visual inspection of internal components. Corrective maintenance is carried out after failure, with emergency repairs to restore equipment functionality,” he explains.
The expansion of solar energy in Brazil also reinforces the importance of sustainable practices in equipment maintenance. Data from the National Electric Energy Agency (Aneel), shared by Portal Solar, indicates that about 3 million residential systems have a total of 20.8 GW of installed capacity, benefiting more than 4 million consumers who have joined distributed generation.
This growth requires greater attention to the reliability of inverters, which support continuous and efficient operation of systems. In this way, Ozora Soluções builds its services in stages that include assembly, advanced diagnostics and specialized repair.
“We issue a free technical report within 24 hours for solar inverters. The repair is done by replacing components, not just entire panels, which can reduce costs and time. We finish with bench tests that simulate real operating conditions and offer an extended 180-day warranty,” Bueno explains.
Furthermore, the company’s laboratory uses state-of-the-art tools to determine the root cause of failure. The repair methodology seeks to restore specific components, avoiding unnecessary replacements. Technical cleaning and deep disinfection are mandatory, and all services undergo tests that reproduce the real environment of the inverter.
According to the company’s CEO, in addition to ensuring energy efficiency, specialized maintenance can also contribute to the circular economy. “By making repairs at the component level, we are able to restore functionality in a cost-effective manner,” he says. “This avoids premature disposal and reduces the need to manufacture new equipment, extending the useful life of the inverters.”
For him, in more than 90% of cases, repair is the smarter choice, both for the customer and for the environment. “We also offer a 24-hour WhatsApp call service, as well as a free kit and a technical team that knows all brands and models of inverters. Our goal is to ensure maximum operational availability for customers,” concludes Bruno Bueno.
