A Solar Fountain idealizes and develops engineering projects, incorporating, integrating and installing photovoltaic solar systems for distributed generation and isolated in Brazil, being a national reference in the off-grid segment (systems isolated from the conventional electrical grid).
The company developed two projects, with the main objective of expanding the concept of sustainability through the photovoltaic sector.
Palicourea House
The institution was designed and aimed at the local community, located close to the Chapada dos Veadeiros National Park, next to Vila de São Jorge, 260 km from Brasília – DF, with the purpose of structuring a connection between technology, culture and sustainability.
Natália Maestá, CEO of Fonte Solar, expressed gratitude when commenting on Casa Palicourea. “It is gratifying to have worked on a project like this, as it is not about things, but about causes”, he stated. The institution received several awards.
According to the CEO, the program faced the challenge of not having a direct network from the dealership to the location. Therefore, the process of converting the Solar Source off-grid Cabinet into an ESS Cabinet (Energy Storage Systems), popularly known as an on-grid system with backup (hybrid), began.
Through changes along the way, the Fonte Solar off-grid Cabinet now offers lithium storage, considered the best in the world, as well as the BYD battery, as well as controllers, controllers, inverter, monitoring screen from Victron Energy in a single solution, with plug and play technology.
To carry out the project, 24 BYD 335 Wp photovoltaic modules, MPPT 150V/35A charge controller, Color Control GX and a BYD 13.8kWh B-Box were used. In addition, two inverters were installed, a Multiplus 48V/5000/70A and a Fronius Primo 5000VA. The total investment for the project was 160 thousand reais.
“The coolest thing about this innovation is that we are deconstructing this reputation that off grid solar energy does not work, because through our franchise system, our franchisees are able to deliver our product to more homes, bringing more human dignity through access to electricity from high quality for remote locations”, said Natália, reporting her satisfaction with the program.
Casa Cavalcante
Casa Cavalcante is located in the Cavalcante-Go region, 340 km from the Fonte Solar company base in Brasília-DF. The project emerged in response to a need in the region's community, due to the difficulty in accessing energy.
The project was developed with the aim of serving the local population with safety in the installation and quality of photovoltaic systems.
According to Natália Maestá, the construction faced some challenges, including difficult access. The distance between the company's base and Casa Cavalcante is 340 km, 30 km of which is on an unpaved road with mountains, taking extra care during transport.
Furthermore, according to Natália, “the climate is unfavorable, with intense and exhausting sun easily reaching 40 degrees” and, therefore, the company took the necessary measures for the team to carry out the work appropriately.
The company followed a certain strategy in off-grid projects, with a larger investment, to avoid future unforeseen events during execution. The equipment to be used goes through an evaluation process in the company's own laboratory. After tests and verification of function, the system is dismantled, packaged and sent to the installation site.
The equipment used to carry out this project were 12 BYD 335Wp photovoltaic modules, a Multiplus-II 48V/3000VA/35A inverter, a Color Control GX, a BYD 7.68kWh B-Box and a Victron Energy MPPT 150V/70A charge controller. The total investment for the project was 70 thousand reais.
“One of the differences in this project is that it is the first installation with lithium iron phosphate storage technology from the largest battery manufacturer in the world (BYD) and control, inverter and management technology from the Dutch company Victron Energy”, highlights Natália.
In order to achieve greater equipment durability, the company invested in high quality products. “Another differentiator was our quality standard in services so that there was no need for maintenance”, he concludes.
