The laboratory of the IEE (Institute of Energy and Environment) of the USP (University of São Paulo) found that the STC peak power (Standard Testing Conditions, in Portuguese, standard test conditions) of the Sunova photovoltaic modules is between 1.14% and 1.65% above the specified peak nominal value, according to available report.
According to what was defined in IEC 60904-3, the STC is equivalent to 1000W/m2, at 25°C of cell temperature, with a solar reference of spectral irradiance called Air Mass 1.5 (AM1.5).
In accordance with the IEC 61215 standard, the modules underwent Visual Inspection, Electroluminescence, Initial Stabilization and Determination of Maximum Power, explains Rafael Palazzo, technical specialist at Sunova Brasil. “We emphasize that to determine the peak power under STC, according to the aforementioned standard, the module must go through the initial stabilization process”, he adds.
According to Wellington Araújo, country manager Brazil at Sunova, the request for such a test was due to another report that was being released in an ineligible manner, so Sunova requested a new test report from the IEE regarding the panels. Thus, the first test was invalidated by USP itself.
“It has already been proven that this report was an unconfirmed product test document, the client and requesting company informed in the report was not even aware of it, according to an official statement already released by it”, added Araújo.
Advances in Photovoltaic Energy in Brazil
ABSOLAR (Brazilian Association of Photovoltaic Solar Energy) analyzes and consolidates sector data and produces an infographic with the scenario of PV solar energy in the country. The last graph, released in March 2023, showed that since 2012 more than 34.5 million tons of CO2 were avoided, 781.6 thousand new jobs were generated and more than 26.0 GW were operational. Nationally, the Brazilian electrical matrix corresponds to 209,120 MW, and regarding 12%, 26,055MW, comes from Solar Fotovoltaica.
Among the advances in the renewable energy sector, Law No. 14,300, of January 6, 2022, stands out, which established the legal framework for microgeneration and distributed minigeneration, the Electric Energy Compensation System (SCEE) and the Renewable Energy Program Social (PERS), allowing consumers to produce their own energy using renewable sources and users are classified as microgenerators.
