Opened in July this year, the first ETE (Sewage Treatment Station) operated using photovoltaic solar energy in Brazil, located in Mogi Mirim (SP), has generated savings of approximately R$22 thousand per month.
According to the company Dinâmica Energia Solar, responsible for the project, the main challenge was to complement the ETE's energy generation through the photovoltaic system, since electrical energy consumption is among the three largest inputs necessary for the operation of waste treatment systems. effluents.
“We carried out a technical-financial feasibility study for the installation of photovoltaic modules in which the size of the project was defined. From this study we were able to estimate the project’s energy savings, as well as define other details”, explains Windson Bernardo, CEO of Dinâmica Energia Solar.
The photovoltaic system has 1.066 JA Solar photovoltaic modules of 400 kWp with X ABB inverters, distributed in three types of installation: roof, ground and carport. “With the installation of this equipment, we were able to project an annual energy generation of 612 thousand kWh and energy savings of around 270 thousand reais in the first year”, adds Commercial Director, Wellington Bernardo.
Another factor highlighted by the company was the possibility of installing photovoltaic panels on the roof of the parking lot, which allows the installation of vehicle chargers to supply the batteries of electric vehicles.
Milestone in the Brazilian photovoltaic market
Considered a milestone in the solar sector in Brazil, SESAMM (Serviços de Saneamento de Mogi Mirim) was the first sanitation services company to invest in energy generation through solar photovoltaic systems and ensure efficiency and sustainability for sewage treatment systems. .
According to the company, the solar plant project complies with all technical standards determined by ANEEL (National Electric Energy Agency) and complies with the technical and regulatory specifications of the electric power concessionaire Elektro, responsible for supplying energy to the municipality.
