Introduction
The National Energy Regulator of South Africa (NERSA) oversees licensing and registration for solar PV systems — ensuring legal compliance, safety, and grid stability. Registration is mandatory for grid-tied systems and recommended for off-grid to access incentives like net metering and insurance coverage.
This guide details who needs to register, the step-by-step process, required documents, and benefits — updated for 2025 with municipality-specific requirements.
Who Needs to Register?
Residential systems below 1 MW usually only require registration through the municipality. Larger installations require a full generation license.

- Municipal Registration: Submit to local authority
- CoC: Certificate of Compliance from electrician
- Fee: R0–R500 (municipality-dependent)
- Time: 2–4 weeks
Commercial (>1 MW)
- Full License: NERSA application + EIA
- Fee: R10,000–R50,000
- Time: 6–12 months
- REIPPPP: For >5 MW projects
