Groot Zorg Fontein: A Green Energy Makeover in South Africa
Groot Zorg Fontein, located in the Western Cape, South Africa, recently underwent a sustainable energy transformation. With a 57.2 kWp grid-tie system facing challenges, the project addressed client concerns and revamped its energy setup.
The client faced issues with an old generator and an inefficient grid-tie system lacking logging capacity.
To tackle this, our commercial team removed an outdated inverter, re-stringed the 57.2 kWp array, and integrated new components for improved efficiency.
The system now features a 45kVA Victron inverter, dual MPPTs, a 100/80 Freedom won battery, and a Fronius Eco 27kVA inverter.
The revamped system annually produces 87.67 MWh, contributing to sustainability goals. With a payback period of 5 years and a 20-year lifespan, it’s both economically and environmentally beneficial, saving 63 tons of CO2 a year.
Groot Zorg Fontein showcases the success of a simple and efficient green energy makeover, providing a reliable power source while contributing to a cleaner, greener South Africa.
