Is solar energy storage worth it in South Africa?

For nearly 15 years, South Africa has been faced with an energy crisis. The country is predominantly reliant on outdated coal plants that require regular maintenance and are often offline, meaning South Africa’s people are constantly living in a state of uncertainty around their power. Households and businesses are plagued by unpredictable and unplanned power outages known as periods of ‘load shedding’, making even the simplest of daily tasks a challenge.

However, solar energy is largely considered to be the long-term solution to South Africa’s power situation. The country’s abundant sunshine and vast open flats make it the perfect candidate for large-scale solar, coupled with the ever-declining prices of solar products and the steadily increasing electricity tariffs.

One of the primary drawbacks of solar power is its intermittency. Whilst solar is the perfect power source during sun hours, a PV installation cannot continue generating electricity at night or on low-irradiation days. Fortunately, battery storage could be the solution. But is it really worth it in South Africa?

The importance of PV batteries

The primary perk of a grid-tied solar PV system at your home or business is the cost savings it offers. With energy tariffs at an all-time high and only creeping up, being able to rely on the sun’s energy during the day instead of Eskom’s expensive power prices is a clear benefit.

However, a common misconception about having solar at your home or business is that the power will keep running during load shedding. However, once the national grid goes offline, all grid-tied solar inverters will switch off, too. To reap the full benefits of solar energy in South Africa, a battery back-up is paramount. Incorporating batteries into a solar installation allows you to store any surplus energy generated for later use when the sun goes down.

So, battery storage is undoubtedly worth it in a country such as South Africa, where there are regular power outages. If the motivations for installing a solar system are centred around having power available during load shedding, then incorporating a battery bank is the only solution.
