Zambia’s solar market is expanding rapidly against a backdrop of severe power deficits and aggressive policy reform. The country receives 5.0 to 6.5 kWh per square meter per day of solar irradiance — among the best in Southern Africa — yet only a fraction of this potential is harnessed. For solar installers and developers, the compliance landscape has shifted significantly: net metering launched in August 2024, mini-grids under 5 MW were deregulated in 2024, and customs duty on solar equipment is suspended through 2027. This guide covers every layer of Zambia solar compliance from ERB licensing and ZESCO grid connection to tax exemptions and rural electrification.
Critical Compliance Point
ZESCO load shedding reached Stage 9 in mid-2025, leaving many customers with only 7 hours of electricity per day. Installers who fail to design battery-backed systems or at least warn clients about grid reliability risk significant reputational damage and callbacks. Always assess a client’s actual grid supply hours before sizing a solar-only system.
ERB Licensing Framework for Solar
The Energy Regulation Board (ERB) is the central licensing authority for all energy-related activity in Zambia. Solar companies must navigate multiple license types depending on their business model.
License Types
| License | Purpose | Validity | Annual Fee |
|---|---|---|---|
| Solar Business License | Trading, importing, installing solar equipment | 1 year | 0.5% of annual turnover from solar sales |
| Generation License | Generating electricity above 100 kW | 3 years | 0.7% of gross turnover |
| Combined License | Generation, transmission, distribution, and supply | 30 years | 0.7% of gross turnover |
| Construction Permit | Building solar plants before generation license | Temporary | 0.1% of total investment cost |
Generation below 100 kW for own use is exempt from ERB licensing. This exemption is important for commercial and industrial clients who want captive solar without regulatory overhead.
Licensing Process Timeline
A well-prepared 5 MW solar project typically requires 9 to 12 months from company registration to operational license:
| Stage | Activity | Timeline | Authority |
|---|---|---|---|
| 1 | Company registration and TPIN | 2-3 weeks | PACRA / ZRA |
| 2 | Feasibility study consent | 4-8 weeks | Ministry of Energy |
| 3 | Environmental approval | 6-20 weeks | ZEMA |
| 4 | ERB construction permit | 9-24 weeks | ERB |
| 5 | Build and grid interconnect | 18-40 weeks | Developer / ZESCO |
| 6 | ERB generation license | 34-42 weeks | ERB |
The ERB issued 474 licenses and 100 construction permits in 2025 alone, with pledged investments of ZMW 67.2 billion. The streamlined Energy Single Licensing System introduced in June 2024 has reduced some processing delays.
Required Documentation
First-time ERB applicants must submit:
- 5-year business plan (3-year for renewals)
- Audited financial statements (not older than 2 years)
- Certificate of incorporation
- Proof of funds (bank statements or sponsor commitment letter)
- Current shareholders and directors list
- Valid tax clearance certificate from ZRA
- ZEMA environmental permit decision letter n- Zonal approval from local council
- Title deed or letter of consent from Chief or Traditional Leader
ZESCO Grid Connection and Net Metering
ZESCO Limited operates the national grid and manages all grid connection processes for solar projects. The utility has two main pathways for solar: net metering for prosumers and power purchase agreements for independent power producers.
Net Metering Programme
Zambia’s net metering framework is governed by the Electricity (Net Metering) Regulations, SI No. 38 of 2024, which took effect on August 1, 2024.
Key Parameters:
| Parameter | Detail |
|---|---|
| System size range | 5 kW to 5 MW |
| Export tariff (2025) | K1.67 per kWh |
| Generation limit | Customer’s contracted or declared demand with ZESCO |
| Meter type | Bidirectional smart meter (prosumer bears cost) |
| Tariff tiers | 100% of reference tariff if exports are 50% or less of generation; 75% if exports are 50-75% of generation |
Program Status (Early 2025):
| Metric | Figure |
|---|---|
| Prosumers connected | 521 |
| Total installed capacity | 15.3 MW |
| Electricity exported to grid | 12,228 MWh |
| Total credits paid out | K3,685,032 |
The application process requires a Competent Person certified by the Engineering Institution of Zambia (EIZ), a single-line diagram, and submission through the ZESCO net metering portal at netmetering.zesco.co.zm.
Grid Connection for IPPs
For utility-scale solar, ZESCO requires compliance with the Zambian Distribution Grid Code. Key technical thresholds include:
| System Size | Requirement |
|---|---|
| Single-phase | Up to 10 kVA |
| Three-phase | Up to 30 kVA |
| Above 100 kVA | Grid impact study required |
| VRES maximum at any POC | 50 MWac recommended |
Developers must fund all interconnection costs including transmission lines, substations, and upgrading existing infrastructure. A Grid Connection Agreement governs the technical, commercial, and legal relationship between the developer and ZESCO.
The Power Crisis Context
Zambia’s energy crisis directly shapes solar compliance and design decisions. Load shedding intensified through 2024 and 2025:
| Period | Load Shedding Level | Supply Hours per Day |
|---|---|---|
| March 2024 | 8 hours daily | 16 hours |
| August 2024 | Up to 17 hours daily | 7 hours |
| May-June 2025 | Stage 9 (17 hours off) | 7 hours |
The crisis is driven by critically low water levels at Kariba Dam, which supplies the majority of Zambia’s hydropower. ZESCO plans to integrate 500 to 800 MW of solar capacity by end of 2025 to diversify beyond the 85% hydropower dependence.
VAT and Customs Duty Exemptions
Zambia offers substantial tax incentives for solar equipment, though the details matter for compliance.
Current Tax Incentives
| Incentive | Rate | Legal Basis | Valid Until |
|---|---|---|---|
| VAT on solar equipment | 0% (zero-rated) | SI 104 of 2021 | Ongoing |
| Customs duty suspension on solar power equipment | Suspended | 2024 Budget | December 31, 2027 |
| VAT on electricity generation equipment | 0% | 2024 Budget | December 31, 2033 |
| Accelerated depreciation | 50% first-year wear-and-tear | Income Tax Act | Ongoing |
Duty Rates by Product (2025)
| Product | Typical HS Code | Customs Duty | VAT |
|---|---|---|---|
| Solar PV panels | 8541.43.00 | 25% | 0% |
| Lithium-ion batteries | 8507.60.00 / 8507.80.00 | 0-5% | 0% |
| Solar inverters | 8504.40.00 | 0-5% | 0% |
| Charge controllers | 8537.10.00 | 0-5% | 0% |
| Solar water heaters | 8419.12.00 | 0-5% | 0% |
| Solar street lights | 9405.41.00 | 0-5% | 0% |
The 25% customs duty on solar panels is a notable exception. While other components enjoy low or zero duty, panels attract the full rate. Importers should structure shipments carefully and verify HS code classifications with ZRA before ordering.
ZRA Requirements
The Zambia Revenue Authority has urged suppliers to pass tax savings to consumers through reduced prices. All importers need:
- Proper HS code classification
- ERB import license (for businesses) or ZRA Self-Declaration form (for individuals)
- Product quality certificates
- Correct documentation for zero-rating claims
When properly structured — especially for imports from South Africa — businesses can achieve 0% export VAT from South Africa plus 0% import VAT in Zambia, saving approximately 31% compared to standard VAT treatment.
Rural Electrification and Mini-Grids
Zambia’s rural electrification rate is approximately 8.1% as of early 2024. The Rural Electrification Authority (REA) targets 40% of rural connections through grid extension, 40% through mini-grids, and 20% through off-grid solar by 2030.
Mini-Grid Deregulation
The Energy Regulation (General) Regulations, 2024 (SI No. 52 of 2024) deregulated mini-grids under 5 MW:
| Capacity | Regulatory Status |
|---|---|
| Under 5 MW | No ERB permit or license required |
| 5 MW and above | Standard ERB licensing applies |
This deregulation is intended to accelerate deployment, but the Africa Minigrid Developers Association (AMDA) has raised concerns. Without permits or licenses, developers lack documentation to secure project finance. The framework works well for small captive solar but creates challenges for investor-backed mini-grid projects.
REA Solar Mini-Grid Projects
The REA has implemented multiple solar mini-grid projects across Zambia:
| Project | Capacity | Connections |
|---|---|---|
| Chilubi Hospital Solar Mini Grid Phase I | 100 kWp | 74 |
| Chief Lundu Solar Mini Grid | 90 kWp | 300 |
| Natukoma Solar Mini Grid | 100 kWp | 250 |
| Chunga SMG | 90 kWp | 87 |
CEC and the Copperbelt
The Copperbelt Energy Corporation (CEC) operates as an independent utility in the Copperbelt region, serving mining and industrial customers. CEC is not subject to ZESCO’s grid code in its licensed area but coordinates with ZESCO for national grid integration.
CEC has emerged as a major solar developer:
| Project | Capacity | Status |
|---|---|---|
| Riverside Solar Plant | 34 MW | Operational since 2018 |
| Itimpi Solar Plant Phase 1 | 60 MW | Commissioned April 2024 |
| Itimpi Solar Plant Phase 2 | 136 MW | Under development |
| CEC-ZESCO co-developed (Phase 1) | 250 MW | Target end of 2026 |
| CEC-ZESCO co-developed (Phase 2) | 250 MW | Target 2027 |
CEC’s total solar target exceeds 800 MW by 2027. The company raised USD 96.7 million through Zambia’s first green bond program specifically for solar expansion.
Building Permits and Local Council Requirements
At the local level, solar installations require building or construction permits from the relevant city or district council. While specific procedures vary by municipality, the general requirements include:
- Site plan or property survey
- Structural analysis for roof-mounted systems
- Electrical single-line diagram
- Solar panel and inverter specifications (ZCSA-certified products)
- Contractor license and insurance
- Proof of property ownership or lease agreement
- Environmental Project Brief (for larger installations)
Lusaka City Council, Ndola City Council, and Kitwe City Council are the most active in processing solar permits. Turnaround times range from 2 to 8 weeks depending on the completeness of the application and the council’s workload.

Open Access and Power Wheeling
The Electricity (Open Access) Regulations, SI No. 40 of 2024 introduced a major reform: private sector players can now access ZESCO’s transmission and distribution networks to sell electricity directly to consumers.
Open Access Categories:
| Category | Duration |
|---|---|
| Long-term | More than 5 years |
| Medium-term | More than 3 months but less than 5 years |
| Short-term | Less than 3 months |
Qualifying participants include traders at 1 MW and above, suppliers at 1 MW and above, and consumers at 1 MW and above. This opens the door for commercial and industrial solar developers to wheel power to off-site customers using ZESCO’s grid for a regulated wheeling fee.
Common Compliance Mistakes in Zambia
| Mistake | Why It Happens | Correct Approach |
|---|---|---|
| Assuming all solar equipment is duty-free | Confusion between VAT zero-rating and customs duty | Verify HS codes with ZRA; panels attract 25% duty |
| Designing grid-tied systems without battery backup | Ignoring load-shedding reality | Size battery storage for client’s critical load during outages |
| Using non-ZCSA-certified products | Cost-cutting on imports | Only import products with valid ZCSA quality certificates |
| Skipping ERB solar business license | Operating informally | Apply for ERB license before trading or installing |
| Missing environmental clearance | Underestimating ZEMA requirements | Submit EPB early; factor 6-20 weeks into project timelines |
Solar Irradiance and Design Data
Zambia’s solar resource is excellent and consistent year-round:
| Location | Annual Average GHI | Peak Months |
|---|---|---|
| National average | 5.0 – 6.5 kWh/m²/day | September-October |
| Lusaka | 5.0 – 5.6 kWh/m²/day | September-October (up to 7.4) |
| Western Province | over 5.7 kWh/m²/day | September-October |
| Southern Province | over 5.7 kWh/m²/day | September-October |
| Copperbelt | 5.2 – 5.8 kWh/m²/day | August-October |

Frequently Asked Questions
What licenses does a solar company need in Zambia?
Solar companies in Zambia need an ERB solar business license for trading, importing, or installing solar equipment. This is renewed annually with a fee of 0.5% of annual turnover from solar sales. For generation projects above 100 kW, an ERB generation license (valid 3 years, renewable) or a combined license (30 years) is required. Construction permits are needed before building any solar plant.
How does net metering work in Zambia?
Zambia’s net metering program launched on August 1, 2024 under the Electricity (Net Metering) Regulations, SI No. 38 of 2024. Prosumers with systems from 5 kW to 5 MW can export excess solar to the ZESCO grid and receive bill credits at K1.67 per kWh (2025 rate). ZESCO installs a bidirectional smart meter at the prosumer’s cost. As of early 2025, over 521 prosumers were connected with 15.3 MW total capacity.
Are solar panels duty-free in Zambia?
Solar equipment benefits from significant tax incentives in Zambia. VAT is zero-rated at 0% on eligible solar imports under SI 104 of 2021. Customs duty on solar power equipment, generators, and components was suspended from July 1, 2024 through December 31, 2027. However, solar panels specifically attract 25% customs duty on CIF value as of 2025. Batteries and inverters typically face 0-5% duty.
What is the solar irradiance in Zambia?
Zambia receives excellent solar irradiance averaging 5.0 to 6.5 kWh per square meter per day, with 2,800 to 3,200 sunshine hours annually. Lusaka averages 5.0 to 5.6 kWh per square meter per day, while western and southern provinces exceed 5.7 kWh per square meter per day. Peak months are September and October, reaching up to 7.4 kWh per square meter per day.
Do mini-grids need a license in Zambia?
Mini-grids under 5 MW are fully deregulated in Zambia under SI No. 52 of 2024 and do not require ERB permits or licenses. This applies to standalone solar mini-grids serving rural communities. The deregulation is intended to accelerate rural electrification, though developers should note that the lack of regulatory documentation can complicate project financing. For mini-grids above 5 MW, standard ERB licensing applies.
