Introduction: Why a Solar + BESS Feasibility Study Matters

The rapid growth of renewable energy is changing how power projects are planned, designed and financed. Solar photovoltaic generation has become an important source of low-carbon electricity, but its output varies throughout the day and depends on solar irradiation and weather conditions.

Battery Energy Storage Systems, or BESS, provide a way to shift, manage and control electrical energy. When solar PV is integrated with battery storage, the combined system can potentially improve renewable-energy utilization, reduce curtailment, support peak demand, provide grid services and increase the reliability of electricity supply.

The International Energy Agency identifies utility-scale batteries as an increasingly important flexibility resource because they can respond quickly, shift renewable generation and provide grid-support services. IEA

For project developers, however, simply combining solar PV with batteries does not automatically produce a commercially viable project.

The project needs to answer fundamental questions:

How much solar capacity should be installed?
What should the BESS power rating be?
How many MWh of battery storage are required?
What duration should the battery provide?
Should the system be AC-coupled or DC-coupled?
How will the battery be charged?
Will charging come exclusively from solar or also from the grid?
What is the expected annual energy yield?
What level of battery degradation should be considered?
What are the grid-connection requirements?
What fire protection and safety systems are required?
What are the CAPEX and OPEX?
What revenue or savings streams will support the investment?
How sensitive is project economics to battery prices, electricity prices and degradation?
Is the project technically bankable and suitable for financing?

These questions form the core of a Solar BESS feasibility study.

For Africa and Europe in particular, project conditions can vary significantly between countries and sites. Grid strength, electricity tariffs, renewable penetration, land availability, permitting requirements, weather conditions, financing costs and market structures all influence the optimal configuration.

A properly executed BESS feasibility study therefore needs to integrate solar resource assessment, electrical engineering, battery sizing, grid studies, safety engineering, CAPEX/OPEX estimation and financial modelling.

1. What Is Solar + BESS?

Solar + BESS refers to an integrated renewable-energy system combining solar photovoltaic generation with a Battery Energy Storage System.

A typical system may include:

Solar PV modules → DC collection → inverter → transformer → grid/load

with the battery integrated through an appropriate power-conversion architecture:

Battery → Battery Management System → Power Conversion System → AC/DC network → load/grid

Depending on the project architecture, the BESS may be:

Co-located with a solar PV plant
Behind the meter at an industrial facility
Connected directly to a distribution network
Connected to a transmission network
Used in a microgrid
Integrated with diesel generation
Integrated with wind and other renewable sources
Designed as a standalone grid-scale BESS
Designed for renewable-energy firming or time shifting

The purpose of a solar plus battery energy storage project depends on the business model.

For example, an industrial facility may use BESS to store excess solar generation during the day and discharge during expensive evening periods.

A utility-scale project may use storage to shift solar generation into higher-value periods.

A weak-grid or off-grid project may use BESS to stabilize the system and reduce diesel-generator operation.

IRENA identifies multiple applications for battery storage, including renewable-energy integration, frequency response, reserve capacity, black start, mini-grids and self-consumption. IRENA

Solar + BESS is not simply “solar plus batteries”

A successful project requires coordinated engineering.

The solar plant affects:

Energy generation
Battery charging opportunity
DC capacity
Grid export
Curtailment
Land requirements

The BESS affects:

Dispatchability
Peak power
Energy shifting
Grid support
CAPEX
Degradation
Fire safety
Auxiliary consumption
Replacement requirements

The Solar BESS feasibility study must therefore evaluate the two systems as one integrated energy project.

2. Why Combine Solar with Battery Storage?

The principal reason for combining solar with BESS is to better align renewable generation with electricity demand and grid requirements.

Solar generation typically peaks around the middle of the day. Electricity demand, however, may peak later.

Without storage, surplus solar energy may need to be:

Exported
Curtailed
Used by local loads
Sold at a lower-value period

With BESS, some of this energy can be stored and discharged later.

2.1 Energy time shifting

One of the most important applications is energy time shifting.

For example:

A solar plant generates surplus energy between 10:00 and 15:00.

The BESS charges during this period.

The battery discharges between 18:00 and 22:00 when electricity demand may be higher.

This changes the temporal value of renewable electricity.

2.2 Peak shaving

For commercial and industrial customers, the BESS may reduce the facility's peak grid demand.

This can be particularly relevant where electricity tariffs include demand charges.

2.3 Renewable firming

Battery storage can reduce short-term variability in solar output.

This can help provide a more controlled generation profile, subject to battery capacity, operating strategy and grid requirements.

2.4 Curtailment reduction

Where the grid cannot absorb all solar generation, storage can potentially capture some otherwise curtailed energy.

2.5 Grid support

Depending on market rules and technical configuration, BESS can provide services such as:

Frequency response
Voltage support
Reserve capacity
Ramp-rate control
Reactive power support
Black-start capability

The exact services available depend on the local electricity market and grid code.

2.6 Energy access and weak-grid applications

Battery storage can be especially relevant in regions where grid reliability is a challenge.

IEA notes increasing deployment of distributed solar PV with storage in countries with unreliable electricity networks, including South Africa. IEA

Africa also has growing examples of solar-storage developments. IRENA has documented solar-plus-storage projects and hybrid renewable developments across African and island markets. IRENA

This makes solar and BESS feasibility study for industrial projects particularly relevant for:

Mining operations
Manufacturing plants
Data centres
Commercial facilities
Water-treatment plants
Remote industrial facilities
Hospitals
Airports
Ports
Telecom infrastructure
Rural electrification
Island grids

3. Project Data Requirements

A high-quality Solar BESS feasibility study begins with reliable project information.

Insufficient input data can result in incorrect sizing, unrealistic financial projections and poorly defined EPC requirements.

A feasibility consultant should establish a structured data request at the beginning of the project.

Solar data

Typical requirements include:

Site coordinates
Available land area
Solar irradiation data
Historical meteorological data
Ambient temperature
Wind speed
Humidity
Soiling assumptions
Topography
Shading information
Site access
Geotechnical information
Flood risk
Existing infrastructure

Electrical data

The study may require:

Existing single-line diagram
Grid voltage
Short-circuit level
Transformer information
Substation information
Grid connection point
Import/export limits
Protection philosophy
Power factor requirements
Grid-code requirements
Existing generators
Existing renewable systems

Load information

For industrial projects:

15-minute or 30-minute load data
Hourly load profile
Monthly energy consumption
Maximum demand
Minimum demand
Seasonal variations
Critical loads
Non-critical loads
Load-growth forecast
Electricity tariff
Demand charges
Time-of-use rates

BESS information

Where a vendor has already been selected, obtain:

Battery chemistry
Rated capacity
Usable capacity
Nominal voltage
Round-trip efficiency
C-rate
Operating temperature
Depth-of-discharge limits
Cycle life
Calendar life
Degradation curve
Warranty
Augmentation philosophy
PCS rating
HVAC requirements
Fire protection requirements

If a vendor has not been selected, the feasibility study should establish appropriate technical criteria for competitive procurement.

4. Load Profile Analysis

Load analysis is one of the most important parts of a BESS project feasibility assessment.

Battery sizing should not be based only on a nominal MW/MWh ratio.

The project team needs to understand when energy is consumed and when renewable energy is available.

Typical load-profile analysis includes:

Daily demand profile
Weekly demand pattern
Monthly demand pattern
Seasonal variation
Peak demand
Minimum demand
Base load
Critical load
Flexible load
Existing generation
Grid import
Grid export
Electricity tariff
Demand charges

For an industrial facility, consider a simplified example.

Suppose:

Peak load = 20 MW
Average daytime load = 12 MW
Evening load = 17 MW
Solar capacity = 15 MWp
BESS = 10 MW / 20 MWh

The feasibility model would simulate:

Solar generation
Facility demand
Solar self-consumption
Battery charging
Battery discharging
Grid import
Grid export
Battery SOC
Battery losses

The result should be an hourly or sub-hourly energy balance.

Why hourly modelling matters

A project can appear financially attractive using annual energy totals while performing poorly when evaluated hour by hour.

For example:

Annual solar generation might be sufficient to meet annual energy demand, but solar generation could occur when the industrial facility's load is low.

BESS changes this relationship by moving energy across time.

Therefore, solar BESS techno-economic analysis should generally be based on time-series modelling rather than annual averages alone.

5. Solar Plant Sizing

Solar sizing determines how much photovoltaic capacity should be installed relative to the BESS and electrical system.

The feasibility study should assess:

DC capacity
AC capacity
DC/AC ratio
Inverter capacity
Module technology
String configuration
Orientation
Tilt
Tracker versus fixed structure
Land availability
Interconnection limit
Energy yield
Curtailment
Battery charging requirements

DC/AC ratio

A solar plant may intentionally install more DC PV capacity than inverter AC capacity.

For example:

100 MWp DC / 80 MW AC

This can improve inverter utilization during lower-irradiance periods but may also increase clipping.

When BESS is integrated, the optimal ratio can change because some surplus energy may be available for battery charging.

Solar resource assessment

A feasibility study should evaluate:

Global horizontal irradiation
Plane-of-array irradiation
Temperature
Wind
Soiling
Availability
Module degradation
Inverter efficiency
Transformer losses
Cable losses
Mismatch losses
Shading
Clipping
Curtailment

The resulting energy model should provide annual and monthly production estimates.

Solar and BESS optimization

The solar plant should not necessarily be sized independently of BESS.

For example, oversizing PV relative to grid export capacity may be beneficial when excess solar energy can charge the battery.

Therefore:

Solar capacity + BESS capacity + grid export limit

should be optimized together.

This is one reason why experienced solar and BESS engineering is important during the feasibility stage.

6. Battery Capacity and Duration

Battery sizing is usually expressed using two primary parameters:

Power rating — MW

and

Energy capacity — MWh

For example:

50 MW / 100 MWh BESS

means the battery system can theoretically deliver 50 MW for approximately two hours at the stated operating conditions.

The simple duration relationship is:

Duration = Energy Capacity ÷ Power Capacity

Therefore:

100 MWh ÷ 50 MW = 2 hours.

However, real projects require additional considerations.

Usable versus nameplate capacity

A 100 MWh nameplate battery may not provide 100 MWh of usable energy throughout its operating envelope.

Consider:

Minimum SOC
Maximum SOC
Efficiency
Temperature
Degradation
Auxiliary consumption
Reserve SOC
Warranty restrictions

Battery degradation

Battery capacity declines over time.

The financial model should therefore consider:

Initial degradation
Annual degradation
Cycle-related degradation
Calendar degradation
Temperature impact
Operating profile
Augmentation

A project designed to operate for 20 years may require battery augmentation depending on technology, warranty and operating strategy.

Choosing duration

Battery duration should be derived from the application.

A project requiring:

Frequency response

may need relatively high power and limited energy.

A project designed for:

Solar shifting

may require longer duration.

A project intended to provide:

Evening peak support

may need several hours of discharge.

Consequently, selecting “two hours” or “four hours” simply because it is common in the market is not sufficient.

The Solar BESS feasibility study should identify the duration that produces the appropriate technical and commercial outcome.

7. BESS Technology Selection

Technology selection is a critical part of energy storage engineering.

Lithium-ion systems, particularly lithium iron phosphate (LFP), are widely used in stationary storage, but technology selection should be project-specific.

The evaluation should consider:

Safety
Energy density
Power density
Cycle life
Degradation
Operating temperature
Efficiency
Availability
Warranty
Supplier bankability
Local support
Spare parts
Fire protection
Environmental conditions
Transportation
Recycling
End-of-life strategy

LFP versus other chemistries

LFP is widely used for stationary applications because of its combination of performance, cost and safety characteristics.

However, the feasibility study should avoid selecting technology solely based on initial price.

A lower initial CAPEX may not necessarily produce the lowest lifecycle cost.

Vendor evaluation

A battery energy storage system engineering consultant should review supplier documentation carefully.

Key vendor documents can include:

Battery datasheet
PCS datasheet
BMS architecture
EMS interface
Thermal management philosophy
Fire detection philosophy
Fire suppression system
Warranty terms
Performance guarantees
Degradation guarantees
Availability guarantees
Efficiency guarantees
Factory test requirements
Certification documentation

The objective is to create a technically consistent basis for tendering.

8. EMS and SCADA

A modern Solar + BESS plant is not simply a collection of batteries and solar modules.

The control architecture is fundamental.

Typical systems include:

Battery Management System — BMS
Power Conversion System — PCS
Energy Management System — EMS
Supervisory Control and Data Acquisition — SCADA
Plant Controller
Protection system
Metering system
Communication network

Battery Management System

The BMS monitors battery operating conditions such as:

Voltage
Current
Temperature
SOC
State of health
Cell balancing
Fault conditions

Energy Management System

The EMS determines how the BESS operates.

Possible strategies include:

Solar charging
Time-of-use arbitrage
Peak shaving
Renewable firming
Frequency response
Reserve
Grid import limitation
Export limitation
Microgrid operation

SCADA

SCADA provides operational visibility.

Typical parameters include:

PV generation
Battery SOC
Battery power
Grid import
Grid export
Voltage
Current
Frequency
Alarm status
Equipment availability
Environmental conditions

A good BESS project consultancy assignment should define the control philosophy before procurement.

9. Grid Integration

Grid integration can determine whether a Solar + BESS project is technically viable.

The feasibility study should establish:

Point of interconnection
Grid voltage
Available capacity
Short-circuit level
Protection requirements
Reactive power requirements
Power factor
Frequency response
Voltage control
Ramp-rate limits
Harmonic limits
Anti-islanding requirements
Metering
Communication
Dispatch requirements

Grid studies

Depending on project size and local grid requirements, studies may include:

Load flow
Short-circuit analysis
Harmonic analysis
Dynamic analysis
Transient stability
Voltage stability
Protection coordination
Flicker assessment
Power-quality assessment

The applicable grid code and utility requirements should be established early.

This is particularly important in international projects because European, African and Middle Eastern grid requirements are not identical.

A BESS technical consultant for renewable energy projects should therefore review the applicable utility and country-specific requirements before freezing the design.

10. Fire Protection and Safety

Battery safety is a critical component of any BESS feasibility study.

Lithium-ion battery systems can experience thermal runaway under certain failure conditions. The consequences can include heat generation, gas release, fire and, depending on circumstances, explosion hazards.

NFPA 855 addresses stationary energy-storage-system installation and includes considerations such as fire protection, ventilation, detection, signage, emergency operations and thermal-runaway hazards. NFPA

The exact standards applicable to a project depend on jurisdiction, technology and project requirements.

Typical safety assessment

A feasibility study should consider:

Battery chemistry
Container layout
Separation distances
Fire detection
Gas detection
Ventilation
HVAC
Emergency shutdown
Fire suppression
Thermal monitoring
Emergency response
Access
Drainage
Hazardous-area considerations where applicable
Firewater requirements
Site emergency plan

Thermal runaway

The design should consider:

Cell failure
Module failure
Propagation
Gas generation
Fire exposure
Re-ignition
Emergency response

Testing and certification requirements should be confirmed during procurement.

Safety should be treated as a core engineering requirement—not as an EPC-stage addition.

11. CAPEX and OPEX

A robust solar BESS feasibility study must establish project cost.

CAPEX may include:

Solar plant

PV modules
Mounting structures
Trackers where applicable
DC cables
Combiner boxes
Inverters
Transformers
MV equipment
SCADA
Monitoring
Civil works
Roads
Drainage
Fencing
Land development

BESS

Battery containers
Battery racks/modules
PCS
BMS
EMS
HVAC
Fire protection
MV transformers
MV switchgear
DC systems
Auxiliary systems
Communication systems

Transformers
Switchgear
Protection
Metering
Transmission line
Communication
Grid studies
Interconnection facilities

Development and indirect costs

Engineering
Project management
Permitting
Surveys
Geotechnical investigation
Environmental studies
Construction management
Testing and commissioning
Insurance
Contingency

OPEX

OPEX may include:

Preventive maintenance
Corrective maintenance
SCADA support
Software licences
Insurance
Land lease
Security
Auxiliary energy
Battery augmentation
Spare parts
Replacement equipment

Battery augmentation should be modelled where required by the degradation assumptions.

12. Financial Analysis

The technical configuration needs to be translated into a financial model.

This is where solar BESS techno-economic analysis becomes essential.

Depending on the business model, the analysis may consider:

CAPEX
OPEX
Electricity revenue
Energy savings
Capacity revenue
Ancillary services
Demand-charge savings
Curtailment reduction
Renewable-energy certificates where applicable
Tax incentives
Grants
Financing cost
Debt-equity structure
Battery replacement/augmentation

Key financial indicators

Common indicators include:

NPV
IRR
Payback period
Levelized Cost of Electricity
Levelized Cost of Storage
Debt service coverage
Cash flow
EBITDA
Project return

Sensitivity analysis

Financial results can change significantly when assumptions change.

The model should test scenarios such as:

Battery CAPEX

What happens if battery cost is 15% higher?

Electricity price

What happens if electricity prices decline?

Solar yield

What happens if actual generation is lower than forecast?

Battery degradation

What happens if degradation is higher?

Interest rate

What happens if financing becomes more expensive?

Availability

What happens if plant availability is lower?

Curtailment

What happens if grid restrictions increase?

The result should identify the assumptions that have the largest effect on project economics.

13. Solar + BESS DPR

After feasibility and techno-economic assessment, many projects require a BESS feasibility study and DPR.

The Detailed Project Report should convert the feasibility findings into an organized project-development document.

A typical Solar + BESS DPR may include:

1. Executive summary

Project objective
Capacity

Configuration
Key findings

Site location
Land
Access

14. Common Design Mistakes

A Solar + BESS project can encounter problems when the feasibility stage is rushed.

Mistake 1: Sizing BESS only by MW

A battery cannot be properly defined by power rating alone.

MW and MWh must be evaluated together.

Mistake 2: Ignoring load profiles

Annual energy consumption does not explain when electricity is required.

Hourly or sub-hourly analysis is often essential.

Mistake 3: Ignoring battery degradation

A battery that starts with a certain capacity may not retain that capacity throughout the project life.

Degradation should therefore be incorporated into technical and financial models.

Mistake 4: Selecting the lowest-cost battery

Lowest purchase price does not necessarily mean lowest lifecycle cost.

Warranty, degradation, efficiency, safety, augmentation and supplier support must be evaluated.

Mistake 5: Treating BESS as a standalone package

The battery must interact with:

Solar
Grid
Protection
EMS
SCADA
HVAC
Fire systems
Civil infrastructure

Integration engineering is therefore critical.

Mistake 6: Delaying grid studies

A technically excellent project can face major delays if the grid connection is not adequately evaluated.

Mistake 7: Underestimating safety engineering

Fire detection, thermal management, ventilation, emergency shutdown and fire protection should be incorporated from the feasibility/design stage.

Mistake 8: Using unrealistic financial assumptions

A feasibility model should clearly identify:

Battery cost assumptions
Solar cost assumptions
Electricity price
Degradation
Efficiency
Availability
Financing
Replacement
Inflation

Mistake 9: Ignoring local conditions

Africa and Europe contain very different market environments.

A BESS project in South Africa cannot simply use the same assumptions as a project in Germany, Spain, Greece, France, Poland or another European market.

Local conditions can affect:

Grid code
Tariffs
Market participation
Permitting
Taxes
Land
Weather
Financing
Equipment logistics
Fire regulations

15. FAQs

What is a Solar BESS feasibility study?

A Solar BESS feasibility study is a technical, commercial and financial assessment of a project combining solar PV generation with battery energy storage.

It evaluates system sizing, energy production, battery capacity, grid integration, safety, CAPEX, OPEX, project economics, risks and implementation requirements.

Why is a BESS feasibility study required?

A BESS feasibility study helps determine whether the proposed battery system is technically suitable and commercially viable before major capital is committed.

It also helps establish the correct battery power, energy capacity, operating strategy and grid connection requirements.

What is solar plus battery energy storage?

Solar plus battery energy storage combines photovoltaic generation with a battery system capable of storing electrical energy and releasing it later.

The configuration can support applications such as energy shifting, peak shaving, renewable firming, self-consumption and grid services.

How is BESS capacity calculated?

BESS capacity depends on the required discharge power, duration, load profile, renewable generation, grid constraints, operating strategy, efficiency, SOC limits and degradation.

For example:

50 MW × 4 hours = 200 MWh

is a simplified four-hour configuration.

Actual usable energy should be determined after considering operating limits and losses.

What is the difference between MW and MWh in BESS?

MW represents the power capability.

MWh represents stored energy.

A 100 MW / 200 MWh system has a nominal two-hour duration.

Suggested Featured Snippet / Key Takeaway

A Solar BESS feasibility study evaluates the technical, financial and commercial viability of combining solar photovoltaic generation with battery energy storage. It typically covers solar resource assessment, load analysis, PV sizing, BESS MW/MWh sizing, battery technology, EMS/SCADA, grid integration, fire safety, CAPEX, OPEX, techno-economic modelling, risk assessment and project implementation planning.

Conclusion

Solar PV and battery storage are increasingly being developed as integrated energy systems rather than independent technologies. Battery storage can help shift renewable generation, improve flexibility and support different grid and industrial applications. IRENA's recent work on firm renewable electricity highlights the growing importance of co-located renewable generation and battery storage in delivering electricity when it is needed. IRENA

But the commercial success of a Solar + BESS project depends on much more than installing photovoltaic modules and batteries.

The project needs a clear technical basis.

It needs an accurate solar-energy model.

It needs a realistic load profile.

It needs correctly sized battery power and energy capacity.

It needs an appropriate battery technology.

It needs a robust EMS and SCADA philosophy.

It needs grid integration studies.

It needs appropriate fire and safety engineering.

It needs realistic CAPEX and OPEX.

And most importantly, it needs a financial model that reflects actual operating conditions, battery degradation, electricity prices and project risks.

That is why a structured Solar BESS feasibility study should be completed before major procurement or investment decisions are made.

For project developers, IPPs, EPC contractors, industrial companies, utilities and investors in Africa, Europe and international markets, the feasibility stage provides an opportunity to identify technical constraints, optimize system configuration and establish the commercial case before committing significant capital.

A well-developed feasibility study can then become the technical foundation for the next stages:

Solar & BESS Concept → Feasibility Study → Solar BESS Techno-Economic Analysis → DPR → Basic Engineering → Detailed Engineering → Tendering → Procurement → Construction → Testing & Commissioning
