When sourcing solar street lights for a distribution order, commercial project, municipal tender or infrastructure project, comparing supplier quotations can be more complicated than simply choosing the lowest price.
Different manufacturers may quote different prices for products that appear to have similar wattage or specifications. One quotation may include the pole and mounting accessories, while another may cover only the solar street light. Battery configuration, solar panel capacity, optical performance, warranty, packaging and shipping terms can also vary.
For B2B buyers, the goal is not simply to find the lowest unit price.
The goal is to identify the most competitive quotation for the same technical requirements and project scope
Before comparing prices, make sure every manufacturer is quoting against the same basic requirements.
Quotation Item | What B2B Buyers Should Check |
|---|---|
Product model | Exact model and configuration |
LED system | LED power, efficiency and specifications |
Optical system | Lens, beam distribution and photometric data |
Solar panel | Type, power and configuration |
Battery | Chemistry, voltage, capacity and usable energy |
Controller | Controller type and charging technology |
Operating schedule | Lighting hours and dimming requirements |
Pole | Height, material and structural requirements |
Accessories | Brackets, cables and fasteners |
Certifications | Required certificates and test documents |
Packaging | Export or customized packaging |
Warranty | Coverage and responsibilities |
Lead time | Production and delivery schedule |
Incoterm | EXW, FOB, CIF, DAP, DDP, etc. |
Shipping | Whether freight is included |
OEM/ODM | Customization requirements |
If important information is missing, the quotations may not be directly comparable.
Do not compare quotations based only on product descriptions such as “100W solar street light.”
Ask each manufacturer to provide the exact model and configuration being quoted.
Check:
LED system
Solar panel
Battery
Controller
Optical system
Housing
Mounting structure
Operating schedule
Two products with the same advertised wattage can have significantly different system configurations.
For B2B procurement, the exact configuration should always be confirmed before comparing prices.
LED wattage is only one part of a solar street light system.
Buyers should compare:
Actual LED input power
Lumen output
Light distribution
Beam angle
CCT
Optical efficiency
Photometric data
IES or LDT files where applicable
Required illuminance
Uniformity
Mounting height
Pole spacing
A higher wattage does not automatically mean better lighting performance.
The key question is whether the proposed configuration can meet the project's actual lighting requirements.
Solar panel capacity directly affects the energy available to recharge the battery.
Check:
Solar panel type
Rated power
Number of panels
Panel dimensions
Panel configuration
Project location
Solar conditions
Charging assumptions
If one manufacturer quotes a larger PV configuration than another, their prices should not be compared without considering the difference in system design.
For the same project, ask all manufacturers to quote according to the same solar conditions and operating requirements.
Battery configuration is one of the most important differences between solar street light quotations.
Check:
Battery chemistry
Nominal voltage
Capacity
Usable energy
Battery configuration
BMS requirements
Operating temperature
Depth-of-discharge assumptions
Required autonomy
Warranty
Do not compare battery capacity using Ah alone.
Different voltage and capacity combinations can result in different energy storage. Nominal capacity also does not necessarily equal usable energy.
For projects requiring reliable overnight operation, ask each manufacturer to clearly state the assumptions behind the quoted battery configuration.
Depending on the project, the system may include:
Solar charging management
MPPT charging
Dimming
Battery protection
Low-voltage protection
Motion sensing
Remote monitoring
However, additional functions do not automatically provide better value.
Ask manufacturers to provide the proposed operating schedule, including:
Lighting start time
Full-power period
Dimming period
Sensor operation where applicable
Total nightly operating hours
This helps buyers compare the energy requirements of different quotations more accurately.
A major price difference can come from whether the quotation includes the pole.
Check whether the quoted price includes:
Solar street light
Pole
Solar panel bracket
Luminaire mounting bracket
Foundation cage
Anchor bolts
Cables
Fasteners
Other installation accessories
If one supplier quotes a complete system while another quotes the luminaire only, the two unit prices are not directly comparable.
Create an included/excluded comparison for each supplier.
Cost Item | Supplier A | Supplier B | Supplier C |
|---|---|---|---|
Solar street light | Included | Included | Included |
Solar panel | Included | Included | Included |
Battery | Included | Included | Included |
Controller | Included | Included | Included |
Mounting bracket | Included | Included | Excluded |
Pole | Included | Excluded | Excluded |
Foundation accessories | Included | Excluded | Excluded |
Export packaging | Included | Included | Included |
Shipping | Excluded | Included | Excluded |
Installation | Excluded | Excluded | Included |
Spare parts | Optional | Included | Optional |
A lower quotation may simply contain fewer items.
Always compare the same supply scope before deciding which supplier is more competitive.
For distributors, wholesalers and importers, customization can affect the quotation.
Make sure every supplier is quoting against the same requirements if you need:
Logo
Private labeling
Customized packaging
Custom color
Housing modifications
Mounting modifications
Product design changes
Customized functions
One manufacturer may quote a standard product while another quotes an OEM configuration.
These prices should not be compared directly.
Always check the Incoterm used in each quotation.
Common terms include:
EXW
FOB
CIF
CFR
DAP
DDP
For example:
Supplier A: FOB China
Supplier B: CIF destination port
Supplier C: DDP project location
These prices represent different delivery scopes.
Whenever possible, ask all manufacturers to quote under the same Incoterm.
The factory unit price is not necessarily the final procurement cost.
A basic calculation is:
Total Landed Cost = Product Cost + Packaging + Freight + Duties + Taxes + Other Required Costs
Depending on the project, additional costs may include:
Local transportation
Customs clearance
Installation
Commissioning
Inspection
Testing
Storage
Spare parts
Engineering support
For importers and project buyers, landed cost can be more useful than the factory unit price when evaluating different suppliers.
Price should also be evaluated together with purchasing quantity and delivery requirements.
Check:
MOQ
Required order quantity
Production lead time
Shipping schedule
Partial shipment options
Production capacity
Peak-season delivery capability
A supplier with a lower unit price may not be the better option if its MOQ or lead time does not match the project.
Two manufacturers may offer similar prices but very different documentation.
Depending on the project and destination market, check for:
Product datasheets
Test reports
Product certificates
IES/LDT files
Lighting calculations
Installation instructions
Warranty documents
Quality inspection records
Component documentation
Packaging specifications
Do not simply check whether a supplier “has certificates.”
Verify that the documents apply to the actual product and configuration being quoted.
For road lighting projects, photometric data can provide a better basis for comparison than marketing specifications alone.
Where applicable, request:
IES or LDT files
Lighting simulation
Illuminance results
Uniformity results
Mounting assumptions
Pole spacing
Installation height
This helps determine whether different quotations can actually meet the same lighting requirements.
A basic procurement calculation can be expressed as:
Total Procurement Cost = Product Cost + Packaging + Shipping + Duties + Other Required Costs
For a complete project, buyers may also need to consider:
Total Project Cost = Equipment + Pole/Structure + Logistics + Installation + Commissioning + Spares + Other Project Costs
The exact calculation depends on the project scope.
The important point is that the quoted unit price should not be the only number used for supplier selection.
For larger projects, buyers can use a standardized quotation comparison sheet.

The purpose of this table is to make every supplier quote against the same technical and commercial requirements.
A low-price quotation may use a different battery, solar panel, optical system or operating schedule.
One quotation may include the pole, brackets and accessories while another excludes them.
FOB, CIF and DDP quotations represent different logistics scopes.
Some projects require specific testing, certification and technical documentation that may not be included in a basic quotation.
Two suppliers may offer similar prices but very different warranty coverage, technical support and spare-parts availability.
The key question should therefore be:
What exactly is included in this price?
rather than simply:
Which supplier is cheapest?
Before sending an RFQ to manufacturers, prepare:
Project location
Application
Required quantity
Road or installation area
Pole height
Pole spacing
Lighting requirements
Operating schedule
Solar conditions
Battery requirements
Environmental conditions
Required certifications
Pole requirements
Packaging requirements
Delivery destination
Required delivery date
OEM/ODM requirements
If you already have a BOQ, RFQ, tender document, lighting design or technical specification, send the same information to every supplier.
If a requirement is not specified, manufacturers may make different assumptions.
Ask suppliers to clearly state assumptions related to:
Solar conditions
Lighting schedule
Battery autonomy
Solar panel configuration
Pole height
Pole spacing
Installation conditions
Delivery scope
This makes quotation differences easier to identify.
Price should be evaluated together with technical and commercial factors.
A practical scoring system could be:
Evaluation Category | Suggested Weight |
|---|---|
Technical Configuration | 20% |
Product Quality | 20% |
Manufacturing Capability | 15% |
Quality Control | 15% |
Certifications & Documentation | 10% |
Project Experience | 5% |
Delivery Capability | 5% |
Warranty & After-Sales | 5% |
Commercial Terms | 5% |
The weighting can be adjusted according to the project.
For example, a municipal tender may place greater emphasis on compliance and documentation, while a distributor may focus more heavily on product consistency, MOQ, OEM capability and long-term supply.
Ask the manufacturer to revise the quotation if:
The product configuration is unclear
Battery specifications are incomplete
Solar panel specifications are missing
The pole scope is unclear
Accessories are not listed
The Incoterm is missing
Shipping costs are unclear
Required certifications are not confirmed
Warranty conditions are incomplete
OEM requirements are missing
The quoted model differs from the requested model
The lighting calculation does not match the project requirements
A revised quotation should clearly identify what has changed.
What exact model and configuration are you quoting?
What solar panel configuration is included?
What battery configuration is included?
What operating schedule is assumed?
Is the lighting performance supported by photometric data?
Are poles and mounting accessories included?
What items are excluded?
What Incoterm is being used?
Is shipping included?
What is the MOQ?
What is the production lead time?
What are the payment terms?
What certifications and test documents are available?
What are the warranty conditions?
Are spare parts available?
What technical support is provided?
Can the product support OEM/ODM requirements?

Comparing solar street light quotations is not simply a matter of finding the lowest unit price.
A reliable B2B comparison should consider:
Product configuration
Lighting performance
Solar panel capacity
Battery configuration
Controller
Pole and accessories
Certifications
Warranty
Delivery terms
Shipping and landed cost
OEM/ODM requirements
Manufacturer capability
The best quotation is not necessarily the cheapest one.
It is the quotation that meets the project's technical requirements, clearly defines the supply scope and provides competitive total procurement value.
For B2B buyers, the best process is:
Standardize Requirements → Request Comparable Quotes → Check Technical Configuration → Compare Total Cost → Evaluate Supplier Capability → Select the Right Manufacturer
