In today’s world, the demand for sustainable and efficient energy solutions is paramount. Solar power has emerged as a viable and environmentally friendly alternative to traditional energy sources. Garden Route Eye Clinic and George Surgical Centre, two prominent health institutions in the region, have taken a significant step towards a greener future by implementing commercial solar power solutions with the help of Specialized  Solar Systems.

These innovative installations are not only reducing energy costs but also contributing to a healthier planet and promoting energy independence.

By incorporating cutting-edge technology from leading brands like Victron and Fronius, these healthcare facilities have harnessed the power of the sun to meet their energy needs. The integration of lithium batteries ensures reliable and efficient storage, providing backup power during load shedding and optimizing energy usage.

Dual Systems for Dual Benefits

There are two separate solar power systems designed and installed for Garden Route Eye Clinic (GREC) and George Surgical Centre (GSC).GREC is equipped with a 3-phase, 45kVA system featuring our very own Energydock Energypod, while GSC has a larger 3-phase, 135kVA system with our very own Storagedock LV-comms stackable batteries. Both systems utilize Victron Quattro’s and Fronius Eco inverters to manage power from Jinko solar panels and store excess energy in LiFPO4 batteries for backup.

Responding to Load Shedding

When both health facilities approached Specialized Solar Systems (SSS) for an energy solution, South Africa was experiencing unprecedented load shedding. Stage 6 load shedding meant disruptions to critical medical services. For these facilities, reliable backup power is essential. Traditionally, this meant relying on diesel generators, but with skyrocketing fuel prices, this solution became increasingly expensive.

Independent Needs, Independent Systems

SSS, a solar power solution provider, commercial team conducted independent energy audits for both GREC and GSC. Each facility has separate electrical infrastructure and operates independently. This analysis determined the specific energy requirements of each location.

Designing for Resilience

Given the critical nature of medical facilities and the prevailing load shedding situation, SSS designed each system with battery storage capacity sufficient to carry the facility through a 4-hour power outage. The battery capacity for GREC is 45kVA 60kWh and for GSC it’s 135kVA 180kWh.

Adapting to Changing Energy Landscape

Since the project’s completion, South Africa’s energy environment has improved, with load shedding currently less frequent. This positive change allows for a more sophisticated approach to battery management.

Optimizing Savings Through Time-of-Use Tariffs

Both facilities operate on Time-of-Use (TOU) electricity tariffs, where the cost of electricity fluctuates based on peak and off-peak periods. SSS can now program the battery charge and discharge cycles to take advantage of these fluctuations. This “arbitrage process” further reduces energy costs and improves the financial viability of the installed solar systems.

Future-Proofing for Growth

The design also considered future expansion plans. A new building is under construction at GSC, with a second phase of the solar power system planned to accommodate the increased energy needs. This phase will add a further 90kVA capacity.

Retrofitting and Aesthetics

The entire system, encompassing both phases, was designed to seamlessly integrate with the existing facilities. This included retrofitting solar panels onto existing roof space and constructing a dual-function solar carport structure. This structure provides shade for visitor parking while accommodating a significant number of solar modules to meet the total energy needs of both facilities.

Meeting Client Objectives

From the outset, the primary goals for both GREC and GSC were energy security, energy independence, and cost savings. These goals encompassed reducing reliance on municipal electricity and minimizing diesel generator running costs. SSS designed the systems with these objectives in mind, while also collaborating with the clients to ensure a visually pleasing integration with the facility grounds.

Operational Success

Both the 135kVA system for GSC and the 45kVA system for GREC are now fully operational. The solar arrays generate sufficient energy to meet the daytime load and charge the batteries during daylight hours. The batteries then discharge during peak tariff periods, significantly reducing electricity costs. Additionally, a secondary charge cycle is scheduled for off-peak hours, further optimizing energy usage.

Conclusion

The successful implementation of solar power systems at Garden Route Eye Clinic and George Surgical Center demonstrates a commitment to sustainable practices and a brighter future. These initiatives not only benefit the institutions themselves but also set an example for others in the community to follow. As technology continues to advance, solar power will play an increasingly important role in meeting the world’s energy needs, especially for critical facilities like medical centers.
