The project is expected to generate a total of 13.5 million kWh hours of clean and reliable electricity annually, equivalent to a reduction of 6,750 tons of carbon emissions and to approximately 1% of the annual electricity generation in the country which is enough to cover the power consumption of 20,000 Nambians.

The Omburu solar plant will use 100 string inverters each with 50kVA output. The use of string inverters were preferred over central inverters because the former need less cables and components and can be installed without special housing, thus, reducing investment costs.

Additionally, the string inverter creates a stable production level as the PV plant can continue to run with very low production losses when one string inverter fails in comparison to much larger losses when a central inverter stops functioning. Delta’s M50A inverters are characterized by a robust and reliable design with a IP65-rated casing made of high quality aluminium, thus, making them an ideal choice for the rugged environment of Namibia.

With its inverters, Delta has made an important contribution to the success of the first-ever utility-scale PV project in Namibia and looks forward to being part of the growing PV market in Africa. Delta plans to continue working with the customer to provide its high efficiency string inverters for more large-scale PV projects in Namibia and the region.
