Key benefits of commercial solar energy solutions:

  • Substantial tax benefits - the capital spend on solar can be depreciated over a year (South African legislation: Section 12B).  
  • Markedly reduce business overheads and increase your bottom line with up to 100% savings on daytime electricity costs.
  • Adds a capital asset to the property thus increases the net worth of the business.
  • Added energy security by pre-purchasing your energy today at a fixed unit cost that will protect your business against foreseeable increases in utility prices.
  • Reduce your reliance on the National Grid.
  • Improve your reputation by contributing to the savings of tonnes of yearly global carbon emissions.
  • Added insulation:  Solar PV panels provide shading thus reducing the need for cooling.


A typical commercial solar solution quotation from Specialized Solar Systems includes:

  • Analysis of your energy usage to provide a realistic demonstration of how much renewable energy can be generated and used on-site.
  • Detailed capitalization calculations that ensure you understand exactly how and when you can expect to break even, the structure of repayments and income and the overall profitability of your business.
  • System deliverables.
  • Detailed system designs upon acceptance.

Mossel Bay Municipality in the Southern Cape province of South Africa has eliminated the carbon footprint of its Technical Services Department buildings by deploying ZBM2 batteries from Redflow.

Installed in late 2016, the four 10 kilowatt-hours (kWh) zinc-bromine flow batteries have enabled the aging offices to become net exporters of electricity to the power grid through the intelligent storage of energy harvested from 114 rooftop photovoltaic solar panels.

Mossel Bay Municipality Electricity and Mechanical Department Senior Manager Charles Geldenhuys said the Redflow energy storage system had exceeded expectations. “We are using more energy now than before the system was implemented,” he said.

“Now if the sun is shining for 50 percent of the day for two weeks, we will not touch the grid except to supply energy to it. It is only when there is a series of overcast days that we will use energy from the grid, so we are now a net contributor of energy rather than a consumer.”

Mossel Bay Municipality is the local government organization for Mossel Bay, a city of 130,000 people located halfway between Cape Town and Port Elizabeth. As well as providing typical local government services, Mossel Bay Municipality retails electricity to people in its area.

Mr Geldenhuys said Mossel Bay Municipality had decided to deploy Redflow batteries to gain experience with energy storage technology. “This is quite a new area for us, so we wanted to get our hands on this technology,” he said.

“We have approved a policy for our consumers so they can use solar to pump energy back into our system, so we decided it would be a good idea to do it ourselves. We have a philosophy that if we put a battery and solar system into our building, we use it to the fullest extent possible.

“We have configured the system so that the building will first draw energy from the solar, and then from the batteries, then pick the grid and, finally, start the generator if none of those are available. We are using the ZBM2 batteries on a daily basis, not just to create a backup system, but to form part of the whole energy system for our office.”

The ZBM2 energy storage system is installed at the municipality’s Technical Service Department office, which employs about 30 people across two adjacent buildings. With extensive use of computers, lighting, and airconditioning, the office contains technical staff and a 24/7 call centre. The facility draws about 120 kWh of energy each day, with a peak demand of 9-11 kilowatts.

Mr. Geldenhuys said he was “more than satisfied” with the service he had received from E-Power Technologies, SSS, and Redflow. “If we have a question, there‘s always a very quick response,” he said. “Also, these Redflow batteries are a clean product. We’ve got the batteries inside our building, two doors down the passage from my office, and there’s no smell and no noise outside the room. So we are very happy with it. We are smiling.”

The Redflow energy storage system installation and configuration were done by JB Snyman of E-Power Technologies, with support provided by long-term Redflow partner, Specialized Solar Systems (SSS).

Mr. Snyman said he had received significant interest in Redflow batteries from other businesses in the region because of their unique benefits including 100 percent daily depth of discharge and their ability to sustain 10 kWh of energy storage capacity throughout their operating life.

Redflow Global Sales Director Andrew Kempster said the Mossel Bay Municipality installation demonstrated the success of Redflow batteries in South Africa. “Along with our Bosco Printed Circuits, this installation at Mossel Bay Municipality demonstrates the value our batteries deliver to commercial customers in South Africa,” he said.

The benefits of Redflow ZBMs compared to other batteries

  • Delivers 100 per cent cycle depth of discharge without any risk of battery damage
  • Retains its full 10 kWh of storage capacity for its warranted 10-year life, unlike other battery types which lose significant storage capacity with age
  • Requires no reserved capacity, unlike other battery types that must reserve a portion of their storage capacity to avoid damage to their battery
  • Has a bromide-based electrolyte which is a natural fire retardant additionally mechanical damage does not risk explosion or ‘thermal runaway’
  • Operates at temperatures as hot as 50°C without active cooling
  • Offers unlimited shelf life: You can switch off a ZBM at any state of charge (SOC), hibernate it for extended periods of time, and then restore it  within 60 seconds
  • Has a great recycling story, made with major components that are easy to recycle or reuse
  • Is a modular system, it is straightforward to connect multiple ZBMs to deliver more energy storage for larger energy storage requirement. As there is no degradation over time, batteries can be added on at any stage
  • The Redflow ZBM is a great battery choice for either AC or DC power, on-grid or off-grid storage energy systems, or a bit of both.
  • 24/7 battery management allows you to use an easy web-based browser via smartphone or PC to set up, monitor, and control your ZBM
  • It also reports battery status and operational information that lets your AC inverter/charger optimise the use of the energy stored in your ZBM
