Hybrid solar solution cuts hospital energy bills by N2m monthly

JMG Solar, the renewable energy arm of JMG Limited, has successfully installed and commissioned a hybrid solar power system at St. Catherine Specialist Hospital in Wuse 2, Abuja, reinforcing the growing adoption of clean energy solutions in Nigeria’s healthcare sector.

The project was designed to improve energy reliability, lower operating costs, and support the hospital’s sustainability objectives. For healthcare facilities where uninterrupted power is critical to patient care and medical operations, hybrid solar systems are emerging as a dependable alternative to conventional energy sources.

According to JMG, the solar installation has significantly reduced the hospital’s dependence on diesel generators and grid electricity. Since commissioning, diesel consumption has dropped by 50 percent—from 2,000 litres to 1,000 litres monthly—resulting in savings of approximately N14 million in diesel costs over four months.

In addition, the hospital’s monthly energy expenditure declined from N7 million to N5 million, generating net savings of about N2 million per month after lease costs, all without any upfront capital investment by the hospital.

Following a comprehensive energy audit, JMG Solar deployed a 92.8kWp solar photovoltaic system, supported by 65kW of hybrid inverter capacity and 160.8kWh of lithium battery storage. The installation comprises 160 Longi solar panels, three 20kW Deye hybrid inverters, one 5kW inverter, and 30 lithium batteries, integrated with a smart monitoring platform for real-time performance tracking.

The system is expected to generate approximately 11.13MWh of solar energy monthly, or 133.63MWh annually, enabling the hospital to meet its entire energy demand through solar generation and battery storage while reducing carbon emissions by an estimated 53,091 kilograms each year.

JMG said the project demonstrates how renewable energy solutions can help healthcare institutions improve operational efficiency, reduce costs, and advance environmental sustainability goals.
