Buying a solar system to Sint Maarten directly from China can provide access to a complete solar package at a competitive equipment cost. However, buyers must consider more than the price of the solar panels.

A successful project requires the correct inverter voltage, sufficient battery capacity, suitable hurricane-resistant mounting, compliant lithium-battery shipping, accurate customs documents and a qualified local installation team.

This guide uses a real shipping quotation for a Sunchees 12kW solar system sent from Foshan, China, to Philipsburg port in Sint Maarten.

The estimated cost for this shipment is:

The estimated shipping time is approximately 80–90 days.

This USD 8,630 project estimate includes the solar equipment, the quoted international freight charges and customs clearance. It does not include final delivery from the port to the property, unloading, installation labor, roof repairs, structural reinforcement or additional electrical materials required at the site.

The destination must be written as Philipsburg, Sint Maarten. Sint Maarten is the Dutch constituent country on the southern side of the island and is legally separate from the French territory of Saint-Martin on the northern side.

How Much Does a Solar System to Sint Maarten Cost?

For this specific project, the estimated solar system cost in Sint Maarten before local delivery and installation is USD 8,630.

12kW solar system cost breakdown

The calculation is:

USD 7,000 + USD 410 + USD 220 + USD 1,000 = USD 8,630

Sunchees currently lists its SPS-12KW off-grid package at USD 7,000, with a stated production lead time of 7–15 days and shipment from Guangzhou or Foshan.

The freight and customs figures above are based on the quotation prepared for this specific shipment. They are not fixed market rates. Before production begins, the freight forwarder should reconfirm the price based on:

• Final cargo volume
• Final gross weight
• Number of pallets and wooden cases
• Lithium-battery classification
• Dangerous-goods charges
• Main-vessel schedule
• Transshipment schedule
• Destination handling fees
• Customs-clearance scope
• Final delivery requirements

Local installation should be quoted separately after the installer reviews the property location, roof, electrical panel and cable distances.

What Does the 12kW Solar System to Sint Maarten Include?

The current Sunchees 12kW solar system is designed as a complete off-grid package for residential, commercial and light industrial applications.

The standard package includes:

The inverter provides pure sine-wave output and is rated at 12,000W. The battery system includes a battery-management system, supports parallel expansion and is listed with a cycle life of at least 6,000 cycles. The solar modules are listed with TUV, IEC and CE certifications and a 25-year warranty reference.

The final configuration can be adjusted according to:

• Daily electricity consumption
• Number and size of air conditioners
• Refrigerators and freezers
• Water and pool pumps
• Cooking appliances
• Maximum simultaneous load
• Required backup duration
• Generator connection
• Grid-input requirements

The final quotation should clearly state the selected solar-panel model, panel quantity, inverter specifications, battery capacity, mounting type, electrical accessories, gross weight and packaging volume.

How Is a Solar System to Sint Maarten Shipped from China?

The planned shipping route is:

Foshan, China → Chinese export port → Caucedo, Dominican Republic → Philipsburg, Sint Maarten

The cargo first travels from the Sunchees facility in Foshan to the Chinese export warehouse or port. It is then loaded onto the main vessel for transport to Caucedo in the Dominican Republic before being transferred to a connecting vessel for Philipsburg.

Estimated shipping schedule

The 15-day Caucedo-to-Philipsburg estimate does not include time spent waiting for the connecting vessel.

Actual arrival may be affected by:

• Vessel schedule changes
• Missed warehouse or port cut-offs
• Transshipment delays
• Limited space on the connecting vessel
• Port congestion
• Customs inspection
• Dangerous-goods approval
• Hurricanes and severe weather
• Incorrect cargo declarations
• Missing shipping marks
• Document corrections

The freight forwarder should provide the planned cut-off date, sailing date, transshipment route and estimated arrival date in writing.

Why Does a Solar System to Sint Maarten Need an Experienced Freight Forwarder?

Shipping solar panels to Sint Maarten requires more than booking ordinary sea freight.

A complete off-grid package contains several different types of cargo:

• Large glass solar modules
• Heavy LiFePO4 battery units
• An inverter
• A combiner box
• Aluminium or steel mounting components
• Electrical cables
• Small accessories
• Potentially regulated dangerous goods

The 2024 Edition of the International Maritime Dangerous Goods Code, including Amendment 42-24, became mandatory on January 1, 2026. The code governs matters such as dangerous-goods packaging, container handling, documentation, stowage and segregation.

The freight forwarder should have experience with:

• Caribbean shipping routes
• Caucedo transshipment
• Philipsburg port procedures
• LiFePO4 battery bookings
• Dangerous-goods declarations
• Solar-panel pallet handling
• Mixed solar-equipment shipments
• Destination customs clearance
• Communication with local destination agents

Questions to ask the freight forwarder

Choosing a freight forwarder only because it offers the lowest base freight rate can result in unexpected destination costs or shipment delays.

What Customs Costs Apply to a Solar System to Sint Maarten?

Sint Maarten generally does not impose ordinary import or export taxes. A government-commissioned business-climate report states that Customs Sint Maarten primarily operates as a law-enforcement body rather than a general import-duty collection agency. The report identifies excise on unleaded gasoline as the main import tax collected by Customs.

However, a duty-free import environment does not mean that the shipment has no destination costs.

The USD 1,000 customs-clearance estimate may include:

• Customs-broker services
• Document preparation
• Cargo-release procedures
• Coordination with the destination agent
• Administrative processing
• Basic port-related handling coordination

Additional costs may arise from:

• Customs inspections
• Storage
• Demurrage
• Detention
• Document amendments
• Repacking
• Port congestion
• Forklift or crane use
• Final delivery

Sint Maarten also has a 5% turnover tax on qualifying goods and services supplied within Sint Maarten. This is different from a general import duty. Whether it applies to the local installation, delivery or commercial transaction should be confirmed with the local contractor, customs broker or accountant.

Before shipping, request a written breakdown showing whether the quoted clearance cost includes:

1. Customs-broker fees
2. Destination-agent fees
3. Port handling
4. Cargo release
5. Inspection fees
6. Storage allowance
7. Local transport
8. Unloading
9. Turnover tax
10. Any battery-related destination surcharge

What Documents Are Required for a Solar System to Sint Maarten?

The shipment should have a complete and internally consistent document package.

The declared product names, quantities, dimensions and weights must match the physical cargo.

The following practices should be avoided:

• Under-declaring cargo weight
• Under-declaring volume
• Omitting the lithium batteries
• Using an inaccurate product description
• Declaring the battery as an ordinary accessory
• Listing quantities that differ from the packing list
• Using different model numbers across documents

Incorrect declarations can lead to inspection, document amendments, additional storage costs, missed transshipment or refusal by the shipping line.

How Should a Solar System to Sint Maarten Be Packed and Marked?

The equipment may spend nearly three months in transit and pass through multiple warehouses, terminals and vessels.

It should therefore be packed for long-distance international sea freight.

Recommended packaging

Every pallet, crate and carton must carry a clear shipping mark.

The mark should include:

• Consignee name
• Destination: Philipsburg, Sint Maarten
• Project or order number
• Package number
• Product description
• Gross weight
• Net weight
• Package dimensions
• “Fragile”
• “Keep Dry”
• “This Side Up”
• Applicable lithium-battery hazard marks

Clear shipping marks are essential during consolidation and transshipment. Missing or unclear marks can cause incorrect sorting, delayed transfer or cargo being separated from the rest of the system.

The panels should also be protected with:

• Strong pallet bases
• Corner protection
• Edge guards
• Moisture protection
• Tight but non-damaging straps
• Impact indicators where practical
• Tilt indicators where practical

Is a 12kW Solar System to Sint Maarten Suitable for Your Property?

A 12kW solar system may be suitable for:

• A house
• A villa
• A holiday rental
• A small shop
• An office
• A restaurant
• A small commercial property
• A property requiring blackout protection

System selection should be based on actual electricity consumption and load behaviour rather than building size alone.

Provide the following information before the system is configured:

• Twelve months of electricity bills
• Average daily electricity consumption
• Daytime consumption
• Nighttime consumption
• Number and size of air conditioners
• Refrigerators and freezers
• Water pumps
• Pool pumps
• Electric cooking equipment
• Water heating
• Office or business equipment
• Maximum simultaneous load
• Motor starting requirements
• Required backup duration
• Existing generator size
• Roof dimensions
• Roof material
• Exact property location

Battery runtime depends on the usable battery energy and the loads that remain active during an outage.

For example, running several air conditioners, a pool pump and electric water heating will consume battery energy much faster than maintaining only lighting, refrigeration, internet, security and selected outlets.

For an off-grid solar system in Sint Maarten, it is often useful to divide the property into:

• Essential backup circuits
• High-priority daytime loads
• Non-essential high-consumption loads

This helps prevent unnecessary battery oversizing while preserving critical power during an outage.

What Electrical Configuration Should a Solar System to Sint Maarten Use?

The public Sunchees package includes a 12kW pure sine-wave inverter with 110V/220V output.

Before manufacturing, the local installer should confirm:

• Required frequency
• Single-phase, split-phase or three-phase supply
• Line-to-neutral voltage
• Line-to-line voltage
• Main-breaker capacity
• Existing generator voltage
• Earthing arrangement
• Required transfer switch
• Grid-input connection
• Generator-input connection
• Zero-export requirement

The final technical specification should clearly state:

Before production, the installer should provide photographs of:

• Electricity meter
• Main distribution panel
• Main breaker
• Generator connection
• Earthing system
• Planned equipment location

Can a Solar System to Sint Maarten Connect to the GEBE Grid?

For a project connected to the GEBE network, the current interconnection, meter, export and approval requirements should be confirmed before finalising the system design.

Sint Maarten’s published National Energy Policy states that small renewable-energy producers may generate electricity for their own use up to 500kVA. The policy also discusses rooftop solar, net metering, feed-in tariffs, grid protection and the need for an interconnection framework.

However, the policy document does not by itself confirm the current approval procedure or guarantee that every customer can export electricity or receive payment for excess generation.

Before ordering a grid-connected or hybrid system, confirm:

• Whether the project requires prior approval
• Whether reverse power flow is permitted
• Whether zero-export control is required
• Whether the electricity meter must be changed
• Required inverter certifications
• Protection and disconnect requirements
• Inspection requirements
• Whether exported electricity is compensated
• The applicable compensation rate
• Required application documents

Where export arrangements are uncertain, the system can be designed for:

• Self-consumption
• Battery charging
• Backup power
• Zero export
• Generator support
• Off-grid operation

This allows the system to provide value without depending on future feed-in revenue.

How Should a Solar System to Sint Maarten Be Designed for Hurricanes?

Sint Maarten is exposed to severe tropical storms and hurricanes. A government report notes that Hurricane Irma damaged approximately 90% of buildings on the Dutch side of the island in 2017.

The solar mounting system should therefore be designed for the actual building rather than selected only from a generic mounting catalogue.

A local structural or installation review should examine:

• Roof material
• Roof age
• Existing roof condition
• Structural attachment points
• Fastener pull-out capacity
• Wind uplift
• Roof edge and corner pressure zones
• Rail spacing
• Clamp quantity
• Anchor type
• Waterproofing
• Array orientation
• Setback from roof edges
• Maintenance access
• Salt-spray exposure

For a coastal environment, the system may require:

• Corrosion-resistant aluminium rails
• Suitable stainless-steel fasteners
• Corrosion-resistant clamps
• Salt-mist-tested solar modules
• Protected cable routes
• Proper bonding and earthing
• More frequent inspection
• Additional attachment points where required by the engineering design

The solar-panel warranty does not replace the need for a structurally suitable roof and mounting system.

If the roof is old, damaged or likely to require replacement within the next several years, it is usually more practical to repair or replace the roof before installing the array.

Can the Equipment in a Solar System to Sint Maarten Be Moved or Wall-Mounted?

The standard Sunchees inverter and battery equipment can be supplied in a floor-standing cabinet fitted with wheels.

This allows the equipment section to be moved when necessary for:

• Maintenance
• Inspection
• Cleaning
• Access to cables
• Reorganisation of the equipment room

The solar panels remain permanently attached to the roof or ground-mounted structure.

The standard wheeled cabinet is not intended to be lifted and attached directly to an ordinary wall.

Wall-mounted option

A separate wall-mounted configuration is available for projects that need the equipment installed above floor level.

A wall-mounted system must account for:

• Wall construction
• Anchor capacity
• Battery weight
• Inverter weight
• Ventilation
• Maintenance clearance
• Cable support
• Vibration
• Emergency access
• Hurricane conditions

Flood-prone properties

In a flood-prone location, raising the battery and inverter above the expected water level can reduce flood exposure.

However, suspending heavy equipment from an unsuitable wall can create a structural hazard. Depending on the property, a reinforced raised platform, elevated equipment room or floor-supported plinth may be safer than a standard wall installation.

The final arrangement should be selected with the local installer after reviewing the building.

What Is the Free Bifacial Upgrade for a Solar System to Sint Maarten?

Sunchees currently offers a free upgrade to double-glass bifacial solar modules for eligible system orders.

The upgraded option is intended to provide:

• More than 1.5% higher module efficiency than the applicable standard option
• Front-side and rear-side electricity generation
• Improved resistance to moisture
• Better long-term structural protection
• Reduced risk of certain backsheet-related degradation
• Improved resistance to mechanical stress
• Reduced hot-spot risk through improved module design

The exact module model, efficiency, dimensions, bifaciality factor and certifications should be stated in the final quotation.

Bifacial modules can generate electricity from light reaching the rear side, but the additional output depends on:

• Roof or ground reflectivity
• Module height
• Tilt angle
• Row spacing
• Shading
• Rear-side obstruction
• Mounting-structure design

NREL research shows that bifacial gain changes substantially with surface albedo, installation height, tilt and array layout.

A bifacial module mounted close to a dark roof may receive limited rear-side light. Better rear-side performance may be possible on:

• Light-coloured roofs
• White concrete
• Reflective ground surfaces
• Elevated structures
• Solar carports
• Open ground-mounted arrays

The free upgrade provides a stronger module platform, but the installer must still design the array so that the rear side can receive useful reflected light.

How Long Does Installation of a Solar System to Sint Maarten Take?

Sunchees works with a local installation partner in Sint Maarten.

For a standard project where the roof and electrical system are ready, the local team can normally complete:

Installation, testing and commissioning in approximately five days

This five-day period refers to on-site work. It does not include:

• International shipping
• Customs clearance
• Permit waiting
• Roof repairs
• Structural reinforcement
• Construction of a battery room
• Major electrical-panel replacement
• Utility approval
• Long underground cable runs

To arrange installation, contact Sunchees and provide the exact project location.
