Support Visionary Care: 3MWp PV Plant in Brazil

Model Type:

10 × SG250HX

Installed Capacity:

3 MWp

Inverter Capacity:

2.5 MW

COD Time:

2023. 07

The Background

In Brazil, the sun is rising on solar power—it is now the second-largest source of energy for the country, supplying more than 20% of the national grid (Source: ABSOLAR). Of the 56 GW of installed capacity, 38.9 GW comes from residential and commercial rooftops, while 17.6 GW powers large-scale utility projects. A powerful example is a solar carport located in Sorocaba's Alto da Boa Vista district. Built to power the nationally recognized ophthalmology hospital BOS (Banco de Olhos de Sorocaba), the project combines advancements in renewable energy with healthcare innovation. It generates enough electricity to support 2,000 low-income homes, bringing light and critical care together under one solar-powered roof.

The Challenges

As the project progressed, a critical technical challenge emerged. For safety reasons, solar inverters—a key component in any solar system—had to be installed in places out of public reach. This meant they couldn't be installed in the open within the public parking area. Installing the inverters in an enclosed space, however, created another problem: heat management. Without proper cooling, the inverter room risked overheating, which could negatively affect both system performance and energy output.

The Solution
The project team partnered with Sungrow to devise a custom, efficient cooling solution. Based on Sungrow's thermal load calculations, the design addressed the project's unique challenges and needs. After extensive deliberation and testing, the teams agreed on a design that enabled the AC system to deliver cool airflow directly to the inverter heat sinks. The solution ensured the inverter room remained within optimal operating temperatures, achieving a perfect balance of safety and efficiency. The result was a system that maximized energy output without compromising performance—turning a potential challenge into a success story.

The Impact
Energy Production
The project generates 4,500 MWh of clean energy per year, cutting the hospital’s energy costs by a significant 30%. This output is equivalent to powering 1,200 Brazilian households annually.
Environmental Impact
The environmental benefits are substantial, with an annual reduction of 7,160 tons of CO₂ emissions. This positive impact is comparable to planting over 45,000 trees or removing more than 1,500 gas-powered cars from the road each year.
Financial Savings
In terms of financial performance, the system saves R$300,000 (~$55,550 USD) in energy costs per month. Over a 30-year period, this is projected to result in total savings of R$100 million (~$18.5 million USD). (Assumes 3% annual energy price escalation)
Smart Infrastructure
The installation doubles as smart infrastructure, providing 789 covered parking spaces and 37 EV charging stations. It is also future-ready, with the built-in capacity to support upcoming eVTOL charging technology.
Technical Excellence
The system’s technical excellence is highlighted by its 98.8% inverter efficiency. Performance is further guaranteed by a climate-controlled inverter room maintained at a stable 25°C (77°F), all overseen by Sungrow’s intelligent real-time monitoring system.
