Warning for Solar Power Users in South Africa Face New Challenges as Eskom tightens its grid-tied solar power systems regulations. This article explores the implications of Eskom’s new rules, the costs involved, and the steps required for compliance.
Understanding Eskom’s Stance on Grid-Tied Solar Power
Eskom, South Africa’s primary power utility, has declared that all grid-tied solar power systems not registered with them are considered “illegal.” This rule applies even if these systems do not feed electricity into the grid.
Eskom also deems a typical Certificate of Compliance (CoC), often issued by qualified electricians for solar installations, insufficient under its new standards.
Eskom’s New Compliance Requirements for Solar Users
Community Meetings and Compliance Demands
Eskom has been actively engaging with solar users through town hall meetings, informing them about small-scale embedded generation (SSEG) rules. During these sessions, Eskom staff emphasized that any solar installation connected to the grid without proper registration violates the law.
One community member shared their experience, explaining that Eskom staff insisted all grid-tied solar systems were illegal due to their potential capability of feeding into the grid.
Mandatory Application and Equipment Installation
Eskom requires solar users to complete an Application Form for SSEG registration. Additionally, customers must:
- Install a bidirectional smart meter.
- Transition to the mandatory Homeflex time-of-use tariff.
- Cover costs for structural modifications, new compliance certifications, and additional equipment.
These changes aim to ensure grid safety and standardize compliance across all connected systems.
Financial Impact of Eskom’s Solar Compliance Rules
The costs of compliance vary based on individual circumstances but often run into tens of thousands of rand.
Examples of Compliance Costs
- A MyBroadband forum member was quoted R27,000 to meet Eskom’s requirements.
- Another community member faced costs as high as R50,000.
These expenses cover:
- A revised and detailed CoC.
- Structural engineer certification to confirm roof strength for solar panels.
- Installation of isolators and additional safety devices.
Alternative Solutions
For some, severing the Eskom grid connection may be more economical. Upgrading inverters, batteries, and panels, or integrating backup fuel generators, enables users to operate independently of Eskom’s network.
The Compliance Process in Detail
To meet Eskom’s standards, solar power users must follow these steps:
- Obtain a Detailed CoC: Ensure the document complies with Eskom’s strict guidelines.
- Structural Engineering Approval: Confirm that the roof structure can handle the weight of solar panels.
- Install Safety Devices: Provide an accessible isolation point and ensure a dead grid safety lock or electromechanical switch is in place.
- Conduct Final Testing: Acquire an embedded generation installation compliance test report from a registered electrician.
Conclusion
Eskom’s tightened regulations pose significant challenges for solar power users in South Africa. While these rules aim to ensure safety and compliance, the financial burden on homeowners is substantial. For many, the decision boils down to either upgrading their systems to sever ties with the grid or bearing the costs to legalize their current setups.
FAQs
1. What happens if I don’t register my solar power system with Eskom?
Unregistered systems are deemed illegal, even if they don’t feed electricity back into the grid. This could lead to penalties or forced disconnection.
2. What is the cost of compliance?
Compliance costs vary but typically range from R27,000 to R50,000, depending on the system and additional requirements like structural assessments.
3. Can I avoid these costs by disconnecting from Eskom?
Yes, upgrading your system to operate off-grid can eliminate the need for SSEG registration and compliance costs.
4. What is a bidirectional smart meter?
A bidirectional smart meter measures both the electricity consumed from the grid and the excess energy fed back into it, facilitating Eskom’s Homeflex tariff.
5. How can I ensure my solar installation is compliant?
Work with a certified electrician to update your CoC, install necessary safety devices, and follow Eskom’s application process for SSEG registration.
