The UBS (Basic Health Unit) in the Avá-Canoeiro indigenous village, in the Minaçu region (GO), has been supplied with solar energy since April this year using a 7,035 kWp off-grid photovoltaic system.
The implementation of the solar plant was made possible by TAESA (Transmissora Aliança de Energia Elétrica SA) through environmental compensation and supervised by Funai (Fundação Nacional do Índio).
The photovoltaic plant was installed by the electrical engineering company Fonte Solar in a carport model, which functions as a secure parking lot for the Funai pick-up truck. Additionally, the roof was replaced with BYD solar panels.
In total, there are 24 335 Wp photovoltaic modules, a 100A charge controller and two 5 KVA Growatt inverters. To store the energy generated by the plant, two 14.4 kWh batteries are used. The total investment was R$ 95 thousand.
“The entire project was a huge challenge. Not only to take the equipment to a remote area, but also to convince the entire tribe that that equipment would bring concrete benefits to the village”, says Natália Maestá, electrical engineer and CEO of Fonte Solar.
“It was extremely gratifying to work on this project, bringing clean and sustainable energy, in addition to contributing to the health and perpetuation of such a warrior people”, added Natália.
According to Growatt, with the charge controller, battery charging must be optimized and remain uniform even on cloudy days.
“Our R&D team, with more than a decade of experience in power electronics, has developed inverters that can meet different requirements of Off-Grid solar plants around the world,” highlighted Lisa Zhang, marketing director at Growatt.
The photovoltaic system must guarantee energy for UBS services in the indigenous village, being capable of keeping medicines and vaccines refrigerated. According to the engineer, the system is being managed remotely and allows the operation of the health center and health care for the Indians 24 hours a day.
In the final stage of negotiations with Funai, Fonte Solar will be responsible for installing a new system to bring solar energy to homes in the village of Avá-Canoeiros, as soon as the Covid-19 pandemic passes.
