Commercial Solar in the Caribbean

Commercial solar is not one standard package across the Caribbean. Your electricity tariff, daytime load, roof condition, grid rules and hurricane exposure determine the right system—and whether battery storage is worth adding.

Where commercial solar usually creates the most value

The best projects use most of the solar electricity on site during the day. Exported electricity may be compensated at a lower rate or restricted by the local utility.

Building type	Common project range	Why solar can fit	Primary design risk	Explore
Hotel & Resort	100kW–2MW	Air conditioning, hot water, pumps and daytime guest loads	Limited roof area and overnight demand	Solar for hotels
Factory	200kW–5MW+	Strong weekday production load and high self-consumption	Motor surge, demand charges and interconnection capacity	Solar for factories
Warehouse	50kW–1MW	Large usable roof area	Roof may be much larger than the daytime load	Business solar
Supermarket & Cold Storage	100kW–3MW	Refrigeration and cooling create steady consumption	Night operation and backup requirements	Commercial storage
School & Office	30kW–500kW	Daytime occupancy often matches solar production	Weekends, holidays and seasonal shutdowns	Solar for schools

The profitable system is not always the largest system

System size should be based on hourly consumption, not roof area alone. A smaller array with high on-site use can deliver a better return than a larger array that exports excess electricity at a low rate.

Commercial Solar in the Caribbean

Choose a commercial solar system size

These are preliminary planning ranges. Final capacity depends on panel wattage, roof geometry, maintenance access, fire setbacks, structural design and the local grid connection limit.

System size	Typical use	Indicative installation area	Recommended system type	Internal page
30–50kW	Small office, shop, school or restaurant	150–400 m²	On-grid or hybrid	On-grid systems
100kW	Supermarket, warehouse or medium hotel	500–800 m²	On-grid / hybrid with optional storage	Hybrid systems
200–300kW	Factory, cold storage or resort	1,000–2,400 m²	Three-phase C&I system	Commercial projects
500kW–1MW	Industrial plant, logistics site or large commercial complex	2,500–8,000 m²	Engineered rooftop or ground mount	Mounting systems
1MW+	Industrial park, campus or utility-scale project	Project-specific	Custom EPC supply package	Request engineering review

Can your building support the system?

A quotation based only on monthly kWh is incomplete. Sunchees uses the following information to narrow the system size before detailed engineering.

Roof or land areaAs a first estimate, allow approximately 5–8 m² per kW.

Roof age and structureOlder metal, membrane or corroded roofs may need repair before installation.

Daytime consumptionOperating hours and hourly load determine how much solar can be used directly.

Shading and equipment zonesWater tanks, HVAC equipment, parapets and nearby buildings affect usable area.

Grid and voltageConfirm phase, voltage, transformer capacity and utility interconnection rules.

Commercial solar rules differ by Caribbean market

Use the country pages for current tariffs, interconnection rules, export compensation, tax treatment and local project constraints. Confirm the latest utility requirements before ordering equipment.

Commercial Solar in the Caribbean

Hurricane-ready design is more than a wind-speed claim

Caribbean projects need project-specific structural design, corrosion control and installation records. The roof and its connections may be weaker than the solar equipment itself.

Wind-load engineering

Define the applicable design wind speed, building exposure, roof zones, uplift loads and connection method.

Coastal corrosion control

Specify suitable aluminium, stainless-steel fasteners, coated equipment and salt-mist-resistant components.

Installation quality records

Require fastening details, torque records, waterproofing checks and post-installation inspection.

Ask these questions before signing

What design standard is being used? What is the design wind speed? How is the racking attached to the structure? Which fasteners and anti-loosening measures are specified? Who signs the structural calculation?

Should the project include commercial battery storage?

Project objective	Battery recommendation	Reason	Related page
Reduce daytime electricity cost only	Not always required	An on-grid system may provide a better return when grid service is reliable.	On-grid solar
Operate during outages	Required	Standard grid-tied solar normally shuts down when the grid fails.	Hybrid solar
Reduce generator runtime	Evaluate carefully	Storage can replace expensive diesel operation during selected hours.	Commercial ESS
Limit solar export	Potentially useful	Batteries can absorb excess midday generation and increase self-consumption.	Solar batteries
Power remote facilities	Usually required	Off-grid systems need enough stored energy for nights and low-sun periods.	Off-grid systems

Commercial solar FAQ

Will commercial solar work during a power outage?

A standard grid-connected system normally shuts down during a grid outage. Backup operation requires compatible battery storage, hybrid inverters, protection equipment and a defined critical-load circuit.

How much roof space is needed for a 100kW system?

A preliminary estimate is approximately 500–800 m². Final area depends on module wattage, roof geometry, access paths, fire setbacks, shading and structural requirements.

Should the system cover 100% of annual electricity use?

Not necessarily. In markets with low export compensation or grid limits, the best financial result may come from a smaller system designed around daytime self-consumption.

Can the system be designed for hurricanes and coastal conditions?

Yes, but “hurricane resistant” should be supported by project-specific wind-load calculations, structural connections, corrosion-resistant materials, documented installation procedures and local engineering approval.

Can Sunchees ship a complete commercial solar system to the Caribbean?

Sunchees can supply solar panels, inverters, batteries, mounting, electrical protection, cables and monitoring as a coordinated package, with export packing, shipping coordination and remote installation support.

Why Sunchees

Why Sunchees Is a Strong Fit for Commercial Solar in the Caribbean

The difficult part of a Caribbean commercial solar project is rarely finding solar panels. The real challenge is making the system design, equipment compatibility, hurricane and coastal requirements, export logistics, local installation and future service work as one project. Sunchees connects those responsibilities as a complete system supplier.

Since 2008Solar manufacturing experience

On / Hybrid / Off-gridMultiple system architectures

OEM / ODMProject customization

SYS

One Coordinated Equipment Package

Solar panels, inverters, batteries, mounting, combiner boxes, protection devices, cables and monitoring can be selected together instead of purchased from unrelated suppliers.

LOAD

Configured Around the Actual Load

The proposal can start from electricity bills, operating hours, motor loads, critical circuits and backup duration—not from a fixed package based only on nominal kW.

OEM

Factory-Level Customization

Voltage, frequency, phase, inverter architecture, battery capacity, cabinet layout, component brands, labeling, packaging and OEM requirements can be confirmed before production.

ISLE

Adapted for Island Conditions

Projects can account for high wind, salt mist, heat, limited grid capacity, generator integration, long replacement lead times and the need to keep critical loads operating.

SHIP

Export and Shipping Coordination

Export packing, container loading, shipping documents, delivery scope and recommended spare parts can be planned as part of procurement rather than handled after the equipment is finished.

ENG

Technical Handover and Support

Drawings, wiring guidance, equipment settings, manuals, remote commissioning support and installer coordination reduce the gap between delivery, installation and stable operation.

The Sunchees Difference Is Scope Control

A commercial buyer often receives an equipment quotation without project support, a local installation quotation without reliable export sourcing, or a generic package without load analysis. Sunchees is most valuable when these separate responsibilities need to be connected.

Project requirement	Generic component seller	Local installer only	Sunchees system-supply approach
Panels, inverter, battery and balance-of-system equipment selected together	Sometimes	Depends on sourcing	Coordinated package
Custom voltage, phase and system architecture	Product dependent	Project dependent	Configured before supply
Export packing and international shipment planning	Basic shipment	Usually outside scope	Included in procurement planning
Installation and commissioning guidance	Usually limited	Local execution	Equipment-side technical support
Local permits, structural approval and utility application	No	When locally qualified	Provides technical data; local approval remains required
Compatible spare parts for an island project	Brand dependent	Local stock dependent	Can be planned with the original order
