460W solar panel

10kW 3-Phase Solar PV + 17.5 kWhr Li-On Battery System – Westdene, JHB

Scope:

We recently concluded an awesome project that the ZPE team worked on for a client in Westdene, Gauteng, South Africa. The system was designed with some novel tech, and successfully commissioned in December 2020.

Location: Westdene, Johannesburg

Technology:

  • Included 22x top of the range 460W monocrystalline solar panels to maximise 10kWp solar capacity within the smallest viable roof footprint
  • Made use of a top of the range 3-phase 10kW hybrid inverter system
  • Coupled with a high voltage 400V DC 17.5kWhr lithium-ion battery system
  • Secondary petrol generator back-up system to ensure 100% uptime for our client’s extremely critical loads on-site

We can’t be happier with the result, with our client sharing these sentiments heading into the holiday period and now enjoying being over 80% off-grid, and free from the worry of load shedding! We are currently in the process of finalising City Power grid feed-in of excess solar power for further savings.

How can we save energy, jobs and costs in Southern Africa post COVID-19?

How can we save energy, jobs and costs in Southern Africa post COVID-19?

The current COVID-19 global pandemic will have far-reaching effects on economies and livelihoods all over the world for a long time to come. As South Africa gradually enters a post-lockdown period, bold and drastically different solutions will be needed to reboot the economy. The power supply challenges of yesterday are not yet behind us, and a shift is required in how we approach power generation and renewable energy. Various sustainability projects can be implemented at a national, local, commercial, and residential level to ease some of the current burdens on resources as we move into a post-COVID-19 South Africa.

Impact of the Pandemic

The novel coronavirus has affected the entire nation, with thousands already infected by the disease. The government, aided by the health sector, is doing all that it can to contain the virus. Measures such as a national lockdown and social distancing, while necessary, make it anything but business as usual.

Looking at the economic impact of the crisis, millions have been affected as their livelihoods were forced to a grinding halt. Many people are now working from home, but for many others, this is not an option. Job layoffs and a rising unemployment rate both during and after the lockdown are expected, with an estimated 1.5 million South African jobs at risk.

For many companies and industries, the crisis has led to a slow-down in output, financial constraints, and business continuity challenges. On the power generation front, a decrease in electricity demand of 7 500MW- 9 000MW during the lockdown period, means that Eskom has been able to provide uninterrupted power. The national power utility has also indicated they are using the opportunity to conduct important maintenance work to its infrastructure. That said, once industries fully resume their operations, the challenge of insufficient power production will once again impact the nation—a nation trying to find its feet after this unprecedented health and economic crisis.

Solutions from Sustainability Projects

Implementing small and large scale sustainability projects could be one way to boost economic recovery and build resilience. These projects span across solar power generation, water efficiency, and other renewable energy deployments.

The International Renewable Energy Agency believes that investments in renewable energy could not only address the climate change dilemma but yield significant economic benefits that could also play a part in the transition to a post-COVID-19 economy.

According to the agency’s director, Francesco La Camera:

By accelerating renewables and making the energy transition an integral part of the wider recovery, governments can achieve multiple economic and social objectives in the pursuit of a resilient future that leaves nobody behind.”

In the next sections, some of the specific solutions we can expect from sustainability initiatives are explored in further depth.

Local Employment Creation

Many people have lost their jobs due to the pandemic and national lockdown. There’s no telling how many jobs will be resumed as things slowly move back to normal. The disease outbreak has also accelerated the use of technology and automation as a further unintended consequence. This, too, could lead to permanent job losses.

The renewable energy industry in South Africa is still relatively new. There is a tremendous opportunity for growth and investment. The country has a very high solar power capacity. The Department of Energy and Renewable Energy  Independent Power Producers (REIPPs) are already in the process of rolling out 27 renewable energy independent power producer projects.  These include solar farms as well as wind farms. Therefore, sustainability projects open many new job opportunities for people who have lost their livelihoods to transition into and acquire the required skills and training.

Localised Energy Production

Once power demand returns to normal levels, the national grid will once again be under a lot of pressure. Localised power generation allows businesses and residences to have some degree of self-reliance. Solar PV solutions are perfectly suited to power daytime consumption of businesses, and even powering evening loads with the aid of battery power storage. This independence from the main power supplier allows businesses and individuals to carry on their operations even in the middle of power shortages, lockdowns, and other unforeseen challenges.

There is another crucial benefit to localized power generation. As this industry grows and import bottlenecks and foreign exchange pressures weigh in,  there will be greater emphasis placed on local equipment manufacturing. This will reduce our reliance on imports, boost local industry, and create local jobs. All these factors will give the economy some much-needed stimulation. For this long-term vision to be a reality, a combined effort is required from all sectors, including research and development partners, technology hubs, and government, whose support will be key.

Cost Saving and Financial Benefits

Solar PV, energy efficiency, and other related alternate energy projects have proven high returns on investment. More than ever, in the current COVID-19 economic climate, investing in solar PV is sure to beat any current money market or equities investments in the short to medium-term. These investments pay for themselves in a few years, and the electricity generated is cheaper and cleaner. There are also additional savings for businesses and residences because of the minimal operational expenses, which free up much-needed cash for other running costs, both now and in the long-term.

Environmental Benefits

Sustainability is all about balancing resources with current needs in a manner that does not negatively impact future generations. This happens on an environmental level, but also has economic and social ramifications.

Solar power is a valuable renewable source of energy, which we are yet to maximize fully. The alternatives, such as coal and oil, release harmful emissions into the environment. Besides solar, other renewable sources of energy are wind and water.

While global industrial production has declined in many sectors in the last few months, pollution and industrial emissions are likely to have also gone down. This has provided an opportunity to reflect on the impact human beings have on the earth and how we can change our ways, moving forward.

Another aspect of sustainability is managing current resources. Water efficiency measures can stop huge water losses at all levels. All these sustainability projects aim to find alternatives solutions and strategies to minimize man’s impact on the environment.

Conclusion

While it won’t be an easy road to navigate a post-COVID-19 South Africa, the government, private sector, and individuals can look to sustainability projects to provide some real, long-lasting solutions. Now is the time to invest in infrastructure and systems that can withstand power supply fluctuations, boost the local economy, create jobs, all while reducing the adverse effects on the environment.
