Rooftop PV system saves money, environment

September 5th, 2019, Published in Articles: Energize

The 1 MW rooftop solar PV system which Siemens installed at its head office in Midrand a few years ago is returning good results. The company reports that the amount of electricity the company buys from the local utility has halved and that the 140 kWh battery provides sufficient power so that the onsite diesel generator is barely used.

Not only is this saving the company money, but is also helping the organisation to achieve its stated intention to reduce its carbon footprint by 50% by 2030. An additional benefit is that, over the last 14 months, the company has experienced no outages, giving it security of supply. The company says the installation, which it refers to as a distributed energy system (DES) will be used as a demonstrator to show other companies what can be achieved by installing a DES at their own premises.
