Solar procurement in South Africa is gaining relevance as industrial companies take a larger role in renewable power purchasing.
According to the Power Futures Lab, 17 independent power producer (IPP) projects with a combined capacity of approximately 1,920 MW reached commercial operation in South Africa during the first half of 2026. Privately procured projects accounted for around 1 GW across 10 installations, all contracted to mining or industrial offtakers.
A further 28 projects could bring total IPP additions to approximately 4,123 MW by the end of 2026.
The 1,920 MW figure covers several technologies and does not represent new solar capacity alone. Seven wind projects accounted for 815 MW. However, the growing influence of private industrial buyers has important implications for the way future solar projects are specified, compared and procured.
Key Takeaway
South Africa’s record IPP activity shows that industrial companies are becoming major buyers of renewable electricity.
For solar procurement, the practical lesson is clear: buyers need to define their energy objective, load profile, equipment scope, technical requirements and delivery responsibilities before comparing offers.

What changed in South Africa’s IPP market?
The 1.9 GW of capacity reaching commercial operation in the first half of 2026 exceeded the capacity added during any full year since 2011. The previous record was approximately 1.5 GW in 2016 and came mainly from publicly procured projects.
The 2026 figures show a different market structure. Privately procured projects delivered approximately 1 GW across 10 installations, with mining and industrial companies acting as offtakers.
This means large electricity consumers are no longer only purchasing power from existing sources. They are increasingly influencing how new renewable generation capacity is financed, contracted and developed.
The figures also show that South Africa’s energy transition is not based on one technology. Wind, solar and energy storage can serve different parts of an industrial energy strategy.
Why does IPP growth matter for industrial solar?
Solar PV can be particularly relevant to mines, factories and commercial facilities with significant daytime electricity demand.
Depending on the site and procurement model, an industrial solar project may be designed to:
- Reduce electricity purchased from the grid
- Improve long-term energy cost visibility
- Supply part of an industrial daytime load
- Increase the use of renewable electricity
- Support a private power purchase agreement
- Deliver electricity through a wheeling arrangement
- Operate alongside battery energy storage
However, purchasing solar equipment is not the same as procuring a complete energy outcome.
The modules, inverters, structures, electrical equipment and monitoring systems must be selected according to the site conditions, load profile, grid arrangement and target commercial operation date.
A successful procurement process therefore starts with the project objective, not with a product catalogue.
What should solar procurement in South Africa include?
A solar request for quotation (RFQ) should provide enough information for every bidder to price the same project using the same assumptions.
Industrial buyers should provide the following inputs:
| Information required | What should be specified |
|---|---|
| Project objective | Cost reduction, renewable electricity supply, energy resilience or private PPA |
| Site information | Location, available area, environmental conditions and grid connection |
| Electricity demand | Annual consumption, daytime load and peak demand |
| Solar capacity | Target or estimated DC capacity in MWp |
| Target date | Required commercial operation date |
| Equipment scope | PV modules, inverters, structures, cables, BESS and EMS |
| Module requirements | Technology, power range, efficiency, dimensions and applicable standards |
| Delivery basis | Incoterm, delivery location, packaging and insurance responsibilities |
| Project responsibilities | Scope assigned to the owner, EPC, suppliers and logistics providers |
| Documentation | Datasheets, certificates, warranties, test reports and commissioning documents |
| Evaluation method | Price, performance, compliance, delivery, warranty and documentation |
These elements allow suppliers to prepare comparable offers and reduce the number of technical or commercial assumptions introduced during bidding.
The RFQ should also specify who is responsible for system design, module selection, inverter integration, mounting structures, grid connection, logistics, testing and commissioning.
How should industrial buyers compare solar modules?
PV module procurement should consider the complete technical and commercial package rather than only the headline power rating or price per watt.
Buyers should compare the exact proposed models using the following criteria:
- Cell technology
- Rated power
- Module efficiency
- Bifacial performance, where applicable
- Temperature coefficient
- Mechanical load resistance
- Dimensions and weight
- Product warranty
- Performance warranty and degradation
- Applicable IEC certificates
- Approved bill of materials
- Product traceability
- Production and delivery schedule
The selected module must also remain compatible with the project’s string design, inverter voltage range, mounting structure and environmental conditions.
A higher module power rating does not automatically guarantee a better project result. Module dimensions, electrical characteristics, temperature behaviour and system design all influence the final installed capacity and expected energy yield.
The objective is to identify the module that best fits the complete solar project rather than selecting one specification in isolation.
What makes a solar equipment offer credible?
A credible solar offer connects every important product claim to verifiable technical documentation.
Before awarding the equipment package, the buyer should be able to confirm:
- The exact module and inverter models
- The approved technical configuration
- The applicable datasheets and certificates
- The product and performance warranties
- The required quality and test documentation
- The production and delivery schedule
- The inspection requirements
- The product identification and traceability process
Commercial terms such as “standard”, “equivalent” or “turnkey” should always be supported by a defined scope.
For example, a turnkey offer should still explain who is responsible for mounting structures, DC cabling, inverter integration, communications, transport, testing and commissioning.
This ensures that the equipment evaluated during procurement remains consistent with what is manufactured, delivered and installed.
When should battery storage be included?
Battery energy storage should be included when it serves a defined technical or commercial purpose.
Depending on the project, a battery energy storage system (BESS) may be used to:
- Store surplus solar generation
- Increase solar self-consumption
- Shift energy to higher-demand periods
- Reduce peak demand
- Limit renewable energy curtailment
- Provide backup power
- Support a specific electricity tariff strategy
A BESS offer must distinguish between power and energy.
MW indicates how much power the system can charge or discharge at a given moment. MWh indicates how much energy it can store. Two systems with the same power rating can therefore provide very different operating durations.
Buyers should also compare usable energy, cell chemistry, cycle conditions, cooling, fire protection, warranty terms and the proposed operating strategy.
Storage should not be added simply because solar and batteries are frequently marketed together. Its size and configuration should be based on the site’s load profile, solar production and intended use.
What role does an energy management system play?
An energy management system (EMS) coordinates solar generation, battery storage, electrical loads and grid exchanges.
Depending on its configuration, an EMS can provide:
- Real-time monitoring
- Solar production and load forecasting
- Battery charge and discharge control
- Peak-shaving strategies
- Alarm management
- Performance reporting
- Multi-site supervision
- Third-party system integration
The operating strategy should be defined during project design because it affects how the battery is sized and used.
A BESS designed mainly for emergency backup will not use the same charging strategy as a system designed for peak shaving or shifting solar energy into the evening.
The EMS is therefore not simply a monitoring interface. It determines how the different components of the energy system work together.
What should happen after equipment selection?
Selecting the equipment supplier is the beginning of project execution, not the end of the procurement process.
Before production and delivery, the owner, EPC and suppliers should confirm four elements:
1. Approved configuration
Confirm the PV modules, inverters, storage equipment, EMS, quantities, electrical interfaces and bill of materials.
2. Document register
List every required datasheet, certificate, drawing, warranty and commissioning document, together with its submission and approval date.
3. Integrated schedule
Connect technical approval, production, shipment, site readiness, installation and commissioning within one project schedule.
4. Final handover
Reconcile the delivered equipment and serial numbers with the approved configuration, warranties and commissioning records.
This continuity helps ensure that the technical assumptions used to evaluate the project are preserved through construction and commissioning.

Frequently asked questions
According to the Power Futures Lab, privately procured projects delivered approximately 1 GW across 10 installations during the first half of 2026. These projects were contracted to mining and industrial offtakers.
No. The 1,920 MW figure covers 17 IPP projects using several technologies. Seven wind projects accounted for 815 MW. The total should therefore not be presented as new solar capacity alone.
A solar RFQ should define the project objective, site and load data, target capacity in MWp, equipment scope, technical requirements, delivery terms, project responsibilities, required documentation and evaluation criteria.
Not automatically. Price should be compared with module technology, efficiency, electrical characteristics, warranties, degradation, certification, traceability and delivery conditions.
MWp represents the DC nameplate capacity of a photovoltaic installation. MW measures instantaneous power, while MWh measures the amount of energy stored or delivered over time.
Battery storage can add value when a project needs to store surplus solar generation, shift energy to another period, reduce peak demand, limit curtailment or provide backup power. Its value depends on the site’s load profile and operating strategy.
An EMS monitors and coordinates solar production, battery charging, electrical consumption and grid exchanges. It can apply operating strategies such as peak shaving, load shifting and solar self-consumption.
