Citrus and solar: a zesty energy partnership
The role of solar and energy storage in the citrus industry
The South African citrus industry is one of the world’s largest, exporting vast quantities of oranges, lemons, grapefruit and other citrus fruits to international markets. However, the industry’s energy needs are significant and growing, particularly due to the reliance on energy-intensive operations such as irrigation, refrigeration, packing and processing. We explore how solar and battery energy storage (BESS) can help address these energy demands, while ensuring the industry remains sustainable for future generations.
The citrus industry is energy intensive
Citrus farming requires a great deal of energy at every stage of the production cycle. From irrigating orchards across vast tracts of land, to maintaining precise refrigeration during storage and transport, energy is vital to ensuring that the citrus fruits meet quality standards, and even more so if the fruit is destined for export. The need for continuous energy supply is particularly acute during peak harvest times when packhouses and cold storage facilities operate at full capacity.
As the industry evolves, future energy requirements may increase. Technological advancements, such as the electrification of machinery and vehicles, will likely demand even more energy. Electric tractors, transport vehicles and automated harvesting equipment are on the horizon, and their adoption will depend heavily on access to reliable and affordable power sources.
Why solar and energy storage are the future for citrus farmers
Solar energy solutions with integrated battery storage offers citrus farmers the opportunity to control their energy costs and reduce their reliance on the grid and fossil fuel. Read our blog on how energy storage has a much wider application than to merely mitigate the effects of load shedding.
Our national grid is under strain, and the citrus industry is not immune to the impacts of unreliable energy supply and grid challenges. Citrus-producing regions such as Limpopo, Eastern Cape and Mpumalanga are all affected by electricity interruptions, which may result in significant losses if refrigeration is compromised or irrigation schedules are interrupted. As Eskom’s capacity issues persist, farmers who invest in renewable energy solutions will be better equipped to maintain smooth operations and avoid costly downtime.
Furthermore, with the eventual transition to electric farm equipment, solar-powered farms will be ideally positioned to meet these new energy demands without incurring significant cost increases.
South Africa's citrus export market and sustainability considerations
South Africa exports millions of tonnes of citrus each year, accounting for a large portion of the country’s agricultural exports. Major destinations include the European Union, the Middle East and Asia. In recent years, buyers from these regions have placed increasing emphasis on sustainability and environmental, social and governance (ESG) factors when sourcing agricultural products.
Adopting solar energy can help citrus farmers meet these growing ESG demands. By reducing their carbon footprint, farms can improve their environmental credentials and appeal to buyers who prioritise sustainable and ethically produced goods. Moreover, solar power offers long-term cost savings, which helps to improve the financial resilience of farming operations - an important factor for the sustainability of farms themselves for future generations.
