Inmetro Opens Laboratory in RJ to Test and Certify Solar Panels, Ensuring More Safety, Quality, and Consumer Protection.

The National Institute of Metrology, Quality and Technology (Inmetro) inaugurated, last Tuesday (22), a modern testing laboratory for solar panels at the Xerém campus in Duque de Caxias (RJ).

The space was designed to expand the national capacity for testing and certifying photovoltaic modules, strengthening market confidence in the products offered in the country. The initiative also targets combating unfair competition and consumer protection, given the increase in equipment with performance lower than declared.

New Inmetro Laboratory Increases Rigor in Solar Panel Testing

With the new structure, Inmetro takes a leading role in the technological and regulatory development of solar energy in Brazil, reinforcing the quality of solar panels and promoting the integrity of the sector.

Entry of Irregular Products Poses Risk to the Photovoltaic Sector

Inmetro warned about the frequent entry of solar panels that have power less than that reported by the manufacturer.

This practice not only deceives consumers but also harms reputable companies and affects the balance of market prices. The new laboratory emerges as an essential tool to curb these distortions, promoting fair competition and technical protection.

João Nery, director of Compliance Assessment at Inmetro, emphasizes that the new structure strengthens national sovereignty in the sector:

“This structure reinforces Brazil’s technological sovereignty in the renewable energy sector and places Inmetro in a prominent position to support the domestic industry.”

The project has the technical support of the National Institute of Clean Energy (Inel), which signed a cooperation agreement with Inmetro. The partnership provides for actions such as training professionals, supporting laboratory operations, and initial maintenance of testing systems.

This collaboration strengthens the testing infrastructure for solar panels in Brazil, creating a more reliable and structured environment for the growth of the clean energy sector.

Regulations Strengthen the Safety of Photovoltaic Systems

In recent years, Inmetro has been improving the regulation of solar equipment in Brazil. With the publication of the Ordinance No. 140/2021, the agency began to require the certification of photovoltaic modules, defining strict technical criteria for their manufacture, sale, and installation.

Furthermore, Ordinance No. 140/2022 made the presence of the National Energy Conservation Label (ENCE), visible to consumers, mandatory, ensuring transparency in product choices.

In 2023, the institute published Ordinance No. 515, which updated safety requirements, incorporating mechanisms for detecting and interrupting electric arcs in the modules—technology that automatically shuts down equipment in case of failures, preventing fires and accidents.

Thus, the initiative not only raises the technical standard of solar panels but also drives the advancement of the clean energy matrix in Brazil.

A Chinese factory in Guangdong is assembling a humanoid robot every 30 minutes while Tesla, Figure, and Boston Dynamics still struggle to deliver 10 thousand per year.

Seven world powers including the US, China, and Russia are spending €22 billion on a reactor in the south of France that aims to confine plasma at 150 million degrees Celsius, ten times the temperature of the Sun’s core, using a magnetic field capable of lifting an entire aircraft carrier.

Secret chamber sealed 4,500 years ago found in the Pyramid of Khufu, and Hawass announces its opening to the world in 2026

With a wingspan of 152 meters, 76 tires, and a capacity to carry 1,270 tons, the Boeing Pelican was the giant “flying ship” that promised to cross oceans close to the water on an invisible air cushion beneath its wings.

A public school student single-handedly created a machine capable of treating water for up to 50 people using only solar energy. It was awarded third place at one of the most important science fairs in the world.

China has begun the second phase of energy assistance to Cuba with a 120 MW solar generation plan, and the first result is a photovoltaic park with batteries that regulates voltage, controls frequency, and provides local autonomy to an island suffocated by chronic blackouts.

Germany installed vertical solar panels on a lake in Bavaria, and the result broke conventional logic: instead of producing energy at midday peak, the plant generates more early in the morning and in the evening, exactly when families turn on appliances and factories are in full swing.

Ford CEO disassembles BYD electric car, is impressed with the speed of the Chinese, and admits that the problem is no longer just the low price.

New equipment for vehicles promises to revolutionize driver safety on Brazilian roads with groundbreaking intelligent anti-sleep seat technology.

Four sisters and their mother moved back in together and gained a house where each perforated brick on the facade filters the sun, the wind, and the street’s gaze: the Vietnamese project Nhà Bè is architecture that breathes through the walls.

Brick is a thing of the past: they created a ‘PET House’ made with 612,000 recycled plastic bottles, capable of withstanding winds of up to 524 km/h, with three bedrooms, two bathrooms, and quick assembly in a few days.

What was decided at the summit between Trump and Xi Jinping in Beijing? According to Chinese diplomacy, the two countries decided to maintain “all” existing trade agreements, create trade and investment councils, and Xi will visit the United States in the fall.

Brazil bets on megabatteries to store solar and wind energy and accelerate sustainable energy transition

A single 560W solar panel was put to the test to try and power an entire house, and the test result shows how much a giant module can truly power a refrigerator, fan, TV, and everyday appliances in daily use.
