Consumers across Brazil will pay more on their electricity bills whenever there is an increase in the cost of producing electricity in the country. Last month, the adjustment of up to 64% of tariff flags approved by ANEEL (National Electric Energy Agency).
With this, the Solar energy presents itself as a viable alternative to reduce electricity expenses, with savings of up to 75%. If in the previous tariff the photovoltaic system was already very economically viable, now, with these high adjustments, it becomes more competitive. Own energy production brings more freedom to the consumer, because he consumes what he generates and deducts the surplus in the compensation system.
In these cases, the impact is much smaller because the additional cost of the flag is only included in the monthly net result of the electricity bill. According to data from L8 Energy, savings for those with photovoltaic systems can reach 75%.
A family in Curitiba, for example, where the energy tariff is R$ 0.83 for each kWh, with monthly consumption of 600 kWh, would spend R$ 498.00 per month on the green flag. If this residence produced 450 kWh monthly, through a solar system, the bill would be R$ 124.50. Check out the simulation carried out by the company's engineering department:

The savings generated may vary according to the generation capacity of each photovoltaic system and the tariffs adopted by each operator. In addition to the financial advantage, the Solar energy brings other benefits to the consumer.
AND environmentally sustainable, as it does not produce any type of waste during generation and uses renewable resources. Furthermore, we have sunlight all year round, which provides a production stability, not depending on rain like the hydroelectric system, for example.
