Consumer Council of MS Warns of Possible Traps in Shared Solar Energy, with Discounts Less Than Promised and Double Billing.

The search for solar energy as a solution to reduce electricity bills has gained momentum in Mato Grosso do Sul.

However, alongside the promise of savings, complaints have arisen. Consumers report that they joined shared solar energy and ended up receiving two bills: one from the distributor and another from the cooperative or consortium contracted.

The warning came from the Electric Energy Consumer Council of MS (Concen/MS). According to the council’s president, Rosimeire Costa, some analyzed cases show that the actual discount was far below expectations. In certain situations, the reduction was only 10% on the tariff.

Two Bills and Savings Less Than Imagined

The central point of the controversy lies in the difference between expectation and reality. Many consumers believe they will stop paying the traditional bill. However, they continue to receive the bill from the distributor, as the power grid remains under its responsibility.

In the case cited by the council, the client consumed about 245 kWh per month. After joining the shared solar energy contract, the compensation would amount to approximately 25 kWh. “What are 25 kWh?” questions Rosimeire. “A fan running eight hours a day for 30 days consumes around 17 kWh. An air conditioner under the same conditions comes close to 238 kWh. In other words, it’s much less than the person imagined.”

Thus, the discount that seemed significant during the sales pitch was revealed to be limited in practice.

Change in Rules Impacts New Contracts

In addition, there is an important regulatory factor. The so-called “boom” in solar energy occurred until January 6, 2023. Those who joined by this date secured more advantageous rules, including the possibility of compensating 50% of the wiring cost until 2045.

On the other hand, those who joined later are already subject to new rules. This means higher payments for using the power grid and, in many cases, smaller deductions on the final bill.

According to Concen/MS, the problem is not the existence of solar farms. “The sale is legal, the businesses are there, we are under the law of economic freedom. But that same law mandates respect for the Consumer Protection Code and ANEEL regulations. It’s not acceptable to lead anyone to believe in a savings that the contract does not guarantee,” asserts Rosimeire.

What to Observe Before Signing

In light of the situation, the council advises caution. Before closing a shared solar energy contract, the consumer should demand a clear simulation, in reais, demonstrating the estimated savings month by month. It is also essential to read all clauses and understand that the distributor’s bill does not disappear.

The promise of reducing the bill may be real. However, without attention to the details, the relief in expenses may be much less than advertised.

What to Observe Before Signing

A British company has installed in the middle of the ocean the world’s first floating platform that generates electricity 24 hours a day from the temperature difference between the surface and the depths of the Atlantic, without relying on wind or sun.

Great Atlantic Sargassum Belt has ceased to be a climatic phenomenon and has become a biological system that feeds on itself, with 8,000 kilometers in length, 37 million tons of algae, and scientists confirm that it is now permanent.

China is building an artificial island in the middle of the sea, covering 20 km², to construct the largest offshore airport in the world, the Dalian Jinzhouwan. This $4.3 billion project is anchored on more than 3,000 pillars embedded in the rock beneath the ocean and is scheduled to open in 2035.

A robot named Walter does the work of five bricklayers per hour and can save the construction industry, where the average age of professionals is 46 years and almost no one wants to learn the trade anymore, in the United Kingdom.

Austrian engineers have developed an inflatable concrete technology that transforms flat slabs into domes using only air pressure, eliminating scaffolding and temporary forms, and potentially changing the way bridges, tunnels, and curved roofs are constructed worldwide.

Engineers had to pour concrete mixed with tons of ice throughout entire nights in the Dubai desert to erect the Burj Khalifa; any carelessness could clog the pipes half a mile high.

The James Webb telescope spotted a planet 700 light-years from Earth with mornings full of sand clouds and nights with clear skies, the temperature difference between the two hemispheres reaches an impressive 170 degrees.

Surprising those seeking their first opportunity, Danone opens internship positions focused on innovation, professional development, and a flexible work model, offering experience in one of the largest multinationals in the food and beverage sector.

While common residences rely on expensive and polluting synthetic materials, a house in Denmark uses seaweed pillows as facade, roof, and insulation, bringing energy savings and preservation of tradition.

Something strange happened in the Earth’s core in 2011, scientists analyzed 27 years of data and discovered a reversed flow under the Pacific that still defies explanations about the planet’s magnetic field.

In the USA, a company ‘cuts through’ the river in Alaska with a submerged turbine that generates electricity 24 hours a day using the invisible force of the current, reducing diesel without relying on wind or sun.

James Webb, NASA’s super telescope, detected quartz crystals in the clouds of a giant planet 1,300 light-years from Earth, where microscopic particles float in a scorching atmosphere and reveal a type of cloud never seen before.

The era of silicon alone in solar energy comes to an end with the arrival of perovskite, a material that captures a broader light spectrum, is applied as a thin film, and, together with silicon, reaches a theoretical limit of 45% efficiency in tandem modules.

Fernando de Noronha begins unprecedented energy transformation with a R$ 350 million solar plant that promises to replace diesel generation and change the island’s sustainable future by 2027.

While Europe and the United States rush to save their own solar chains, China already dominates more than 80% of the global manufacturing of solar panels and has turned the sun into an industrial machine controlled by Beijing that is redefining the global energy transition.
