A well-prepared BOQ allows project buyers to request comparable quotations from qualified solar street light manufacturers and reduce missing items, unclear scope and unexpected project costs.
A Bill of Quantities (BOQ) is a structured list of the products, materials, services, quantities, and commercial items required to complete a solar street light project.
For B2B solar lighting projects, the BOQ is more than a simple product list. It connects the project design, technical requirements, quantities, installation scope, and quotation into one procurement document.
A typical solar street light BOQ may include the lighting system, solar PV module, battery, controller, pole, mounting accessories, foundation, cables, installation, testing, commissioning, and maintenance.
Public procurement documents show this approach in practice. Recent solar street lighting tenders have separated the technical tender documents from the financial BOQ, while some BOQs separately identify PV modules, batteries, luminaires, controllers, poles, erection, and long-term maintenance.
These three documents serve different purposes.
BOQ defines what is required and how much is required.
RFQ asks suppliers how much they will charge for the required scope.
Technical specification defines the performance and technical requirements that each item must meet.
For example:
BOQ: Solar street light system — 500 units
Technical specification: Required lighting performance, system configuration, protection, materials, and operating requirements
RFQ: Supplier's unit price, total price, delivery terms, and commercial conditions
A strong project normally uses these documents together rather than treating the BOQ as a standalone product list.
A detailed BOQ helps project buyers:
Compare quotations from different suppliers
Reduce missing items
Clarify the supplier's scope of supply
Control project costs
Reduce technical misunderstandings
Support tender evaluation
Coordinate installation and commissioning
Plan spare parts and maintenance
For example, a recent public solar street light tender included supply, installation, testing, commissioning, and a multi-year comprehensive warranty and maintenance scope rather than treating the luminaire as the only deliverable.
Each BOQ item should have a clear description.
Instead of writing:
Solar street light — 500 pcs
a project BOQ should identify the required system and reference the applicable technical specification.
The description can include:
Product category
System configuration
Required performance
Materials
Mounting method
Protection requirements
Applicable standards
Required accessories
This gives manufacturers enough information to prepare a compliant quotation.
Every BOQ item should have a clearly defined unit and quantity.
Common units include:
pcs / units
set
meter
lot
job
project
For example:
Item | Unit | Quantity |
|---|---|---|
Solar street light system | Set | 500 |
Street light pole | Pcs | 500 |
Foundation | Set | 500 |
Cable | m | Project-specific |
Installation | Job | 1 |
Testing & commissioning | Job | 1 |
The exact quantities should come from the project design and site requirements rather than being estimated from the product wattage alone.
For procurement, the commercial section normally needs:
Unit rate
Quantity
Total amount
Applicable taxes
Currency
Delivery or installation costs where applicable
A standard BOQ structure commonly uses item description, unit, quantity, unit rate, and total amount.
A project may specify:
A required brand
A preferred manufacturer
A specific model
Or an “approved equivalent”
For international B2B procurement, it is often better to define the required technical performance and allow technically equivalent products when the project permits it.
This can give buyers access to more qualified manufacturers while keeping the technical requirements controlled.
The BOQ should clearly state whether the supplier is responsible for:
Delivery
Pole installation
Foundation work
Solar panel installation
Electrical connections
System commissioning
Testing
Site acceptance
A recent Central University of Rajasthan tender, for example, specified design, supply, erection, installation, testing, and commissioning as part of the solar street lighting work.
The main luminaire entry should define the required lighting system rather than only stating LED wattage.
Depending on the project, requirements may include:
LED lighting technology
Optical system
Light distribution
Housing material
Protection rating
Operating environment
Dimming or lighting profile
Mounting method
Required lighting performance
Some public BOQs specify the luminaire separately from the PV module, battery, controller, and pole.
The BOQ should identify the required solar PV module or system capacity according to the project's energy design.
Potential requirements include:
PV technology
Required capacity
Module efficiency
Mechanical construction
Environmental suitability
Certification
Mounting arrangement
The panel should not be specified independently from the overall energy requirement.
The battery is one of the most important BOQ items because it directly affects system autonomy and long-term operation.
The specification may define:
Battery technology
Nominal voltage
Required energy capacity
Battery management system
Operating temperature
Protection
Enclosure
Expected service requirements
A project BOQ should avoid simply listing battery capacity without explaining the system's required operating performance.
The controller may be integrated into the luminaire or specified as a separate component.
The BOQ should clarify:
Controller type
Charging technology
System voltage
Protection functions
Dimming control
Battery management
Communication or remote monitoring requirements
Small components are easy to overlook but can create problems during installation.
Depending on the system, the BOQ may need to include:
Pole brackets
Panel mounting structures
Clamps
Fasteners
Cable glands
Connectors
Junction boxes
Earthing accessories
Other mounting hardware
The pole should normally be a separate BOQ item when it is not integrated into the lighting system.
Requirements may include:
Pole height
Material
Shape
Wall thickness
Surface treatment
Base plate
Foundation bolts
Mounting arm
Access door
Wind-load requirements
Recent public BOQs demonstrate how detailed pole requirements can become, including material, galvanizing, base plates, foundation bolts, access doors, and structural requirements.
For project procurement, the foundation scope should be clearly defined.
The BOQ can specify whether it includes:
Excavation
Concrete
Reinforcement
Anchor bolts
Formwork
Backfilling
Foundation installation
If civil works are excluded, that should also be stated explicitly.
Depending on system design, the BOQ may include:
DC cables
AC cables for hybrid systems
Connectors
Junction boxes
Protection devices
Earthing materials
Cable glands
Conduits
The exact cable specification should be based on the system design and installation conditions.
A professional BOQ should look beyond wattage.
Relevant requirements can include:
Light output
System efficacy
Light distribution
Color characteristics
Optical performance
Housing
IP protection
Impact resistance
Operating temperature
Dimming profile
This prevents suppliers from competing purely on nominal wattage while delivering substantially different lighting performance.
The BOQ should connect the PV specification to the project's energy requirements.
Instead of treating the panel as an isolated component, the project specification should consider:
Solar resource → PV generation → battery charging → nighttime load → required operating profile
Battery requirements should be linked to:
Nighttime operating schedule
Dimming profile
Required autonomy
Environmental conditions
Charging conditions
Expected replacement strategy
This gives suppliers a clearer basis for system engineering.
Pole requirements should include both physical and structural considerations.
Important factors include:
Height
Mounting arrangement
Wind conditions
Material
Surface treatment
Foundation interface
Maintenance access
A project BOQ may also reference requirements for:
Water and dust protection
Corrosion resistance
Temperature
Humidity
Wind
UV exposure
Impact resistance
The requirements should match the actual project environment rather than simply using the highest available protection rating.
The quantity should be determined from the project layout and lighting design.
Factors can include:
Road length
Road width
Pole height
Pole spacing
Mounting arrangement
Light distribution
Required illumination
Required uniformity
Intersections and special areas
The number of luminaires should therefore be connected to the lighting design rather than calculated only from road length.
In a typical standalone system, the number of poles may correspond to the number of lighting points.
However, project layouts can include:
Single-sided arrangements
Staggered arrangements
Opposite arrangements
Median-mounted lighting
Special intersection lighting
Therefore, the BOQ should follow the approved layout.
Cable quantities depend on the system architecture.
For an integrated solar street light, the cable requirement may be relatively limited compared with conventional grid-connected street lighting.
For hybrid or split systems, additional wiring and accessories may be required.
Large projects should consider spare parts before procurement.
Possible items include:
LED modules
Controllers
Battery components
Connectors
Fuses
Mounting hardware
Other replaceable components
Including spare parts in the original BOQ can make future maintenance easier and reduce procurement delays.
In a supply-only project, the manufacturer may be responsible for:
Production
Quality control
Packaging
Documentation
Delivery
Installation remains the responsibility of the buyer or local contractor.
For turnkey projects, the supplier may also provide:
Transportation
Civil works
Pole erection
Luminaire installation
System assembly
Testing
Commissioning
These responsibilities should be clearly identified in the BOQ.
Testing and commissioning should not automatically be assumed to be included.
They should be explicitly identified as part of the scope.
This is particularly important for public and commercial projects where project handover may depend on successful testing.
Long-term maintenance can also be included as a separate BOQ item.
A current public procurement example specifies a five-year comprehensive warranty and operation and maintenance requirement as part of the solar street lighting scope.
Every supplier should receive the same:
BOQ
Technical specification
Project layout
Lighting requirements
Commercial conditions
Otherwise, the lowest quotation may simply be the quotation with the least scope.
“LED street light — 40W” is not enough to compare different systems.
Two products with the same nominal wattage can have different:
Light output
Optics
Efficiency
Thermal management
Lighting distribution
Operating profiles
Performance-based requirements create a more meaningful comparison.
The quotation should clearly identify what is included.
For example:
Luminaire + PV module + battery + controller + pole + mounting accessories
rather than simply:
Solar street light set
The BOQ should state whether the quoted price includes:
Freight
Installation
Foundation
Cabling
Testing
Commissioning
Spare parts
Documentation
Warranty service
This prevents unexpected costs later.
“Complete set” can mean different things to different suppliers.
Instead, list the individual components and services.
This makes quotations easier to compare and reduces disputes during delivery.
For projects requiring professional lighting design, the selected luminaire should be supported by appropriate photometric data where required.
This allows the lighting design to be evaluated independently from the commercial quotation.
The BOQ should correspond with the product used in the lighting simulation.
For example:
BOQ product → Photometric file → Lighting calculation → Project layout
If the supplier substitutes a different optical system after the simulation, the lighting result may no longer represent the quoted product.
These three factors should be considered together.
Changing the pole height or spacing without reviewing the optical distribution can change:
Illuminance
Uniformity
Dark areas
Lighting coverage
A common project problem is having one product listed in the BOQ while another product is used for the lighting calculation.
Buyers should request confirmation that the:
Model
Optics
Installation height
Mounting angle
Pole spacing
match the approved project design.
A simplified supply-only BOQ could look like this:
Item | Description | Unit | Quantity |
|---|---|---|---|
1 | Solar street light system | Set | 500 |
2 | Street light pole | Pcs | 500 |
3 | Mounting accessories | Set | 500 |
4 | Spare parts | Lot | 1 |
5 | Technical documentation | Lot | 1 |
The actual technical requirements should be referenced separately rather than trying to place every specification into a single table.
A larger project may separate supply from site work:
Item | Description | Unit | Quantity |
|---|---|---|---|
1 | Solar street light system | Set | 500 |
2 | Street light pole | Pcs | 500 |
3 | Foundation works | Set | 500 |
4 | Installation and erection | Job | 1 |
5 | Testing and commissioning | Job | 1 |
6 | Spare parts | Lot | 1 |
For a turnkey project, the BOQ may include:
Equipment + civil works + installation + testing + commissioning + documentation + warranty + maintenance
This approach is common in larger public procurement projects, where the scope can extend well beyond the supply of lighting equipment.
A wattage-only BOQ can lead to technically different products being treated as equivalent.
Battery specifications should support the required operating profile rather than simply listing a nominal capacity.
A lighting system cannot be installed if essential mechanical components are missing from the procurement scope.
Buyers should state whether installation is:
Included
Excluded
Optional
Provided by another contractor
Testing should be clearly assigned to the responsible party.
Large projects can become difficult to maintain when no replacement components are planned.
A BOQ such as:
“Solar street light, complete set”
does not provide enough information for serious technical comparison.
A manufacturer should first review:
Project location
Road layout
Lighting requirements
Pole arrangement
Environmental conditions
Installation scope
Delivery requirements
The engineering team can then match the required:
LED → optics → PV → battery → controller → pole → mounting system
to the project requirements.
A professional supplier should identify unclear items before submitting a final quotation.
For example:
Missing road width
Missing pole height
Undefined lighting performance
Unclear installation scope
Missing environmental conditions
Unclear warranty requirements
The final proposal should make it easy for the buyer to see:
BOQ requirement → Proposed product → Technical compliance → Quantity → Price
This is particularly important in competitive tenders.
An experienced manufacturer should not simply provide a price based on the item quantity. The supplier should review the technical requirements, system configuration, lighting design and project scope before preparing the quotation.
Request datasheets for the major system components.
Drawings can help confirm:
Dimensions
Mounting
Pole interface
Installation requirements
Product construction
Where professional lighting calculations are required, request the appropriate photometric files for the proposed luminaire.
For solar projects, the supplier should be able to explain how the proposed system supports the required operating profile.
Depending on the project and destination market, buyers may require relevant:
Product certificates
Test reports
Factory inspection documents
Quality documents
Compliance declarations
The exact documents should be determined by the tender and applicable market requirements.
The commercial offer should clearly state:
Warranty scope
Warranty period
Replacement process
Spare parts availability
After-sales support
If you are comparing solar street light suppliers, request these documents before making a final purchasing decision. They can help you verify whether the quoted product actually meets your BOQ and project requirements.

Maintenance scope
A manufacturer can provide a more accurate proposal when the BOQ is accompanied by:
Project location
Road information
Site conditions
Lighting requirements
Pole arrangement
Required quantity
Delivery destination
Installation requirements
If available, provide:
Road plans
Site maps
Pole layouts
Cross-sections
Existing lighting information
These documents allow the supplier's engineering team to review the project rather than simply quote a generic product.
Clearly identify the required lighting outcome.
This is more useful than specifying only a nominal LED wattage.
State whether you need:
Supply only
Supply and installation
Turnkey project delivery
Testing and commissioning
Long-term maintenance
Before comparing final quotations, ask suppliers:
Does the quotation cover every BOQ item?
Are any components supplied by others?
Does the proposed product match the technical specification?
Does the quoted product match the photometric design?
Are installation and commissioning included?
What documents will be provided?
What is covered by the warranty?
Are spare parts available?
What is the production and delivery schedule?
Can the supplier provide a project-specific technical proposal?
A well-prepared Solar Street Light BOQ should do more than list quantities and prices.
It should connect the entire procurement process:
Project Requirements → Technical Specification → BOQ → Supplier Proposal → Quotation → Delivery → Installation → Testing → Handover
For B2B buyers, the goal is not simply to find the lowest unit price. The goal is to make sure every supplier is quoting against the same technical scope and project requirements.
For manufacturers, a detailed BOQ also provides a much clearer basis for engineering review and quotation.
If you already have a solar street light BOQ, send the project requirements to the manufacturer and ask for a technical compliance review together with the commercial quotation. This can help identify missing items, technical mismatches, and scope gaps before the project moves to procurement.
