Overview

A commercial rooftop PV procurement package for buyers working with a local EPC or installer. It coordinates modules, string inverters, racking interfaces, cable and protection items, model documentation, and delivery sequencing. It is not a substitute for local structural, electrical, fire-safety, or interconnection design.

Commercial Rooftop Solar equipment configuration

Common Challenges

Roof geometry, obstructions, electrical service, and mounting interfaces vary from building to building.
Commercial buyers need equipment records and documentation that their local EPC can review.
Delivery needs to align with receiving capacity and installation sequencing, not just container availability.

Our Approach

Use the EPC's preliminary layout and electrical design as the basis for the supply schedule.

Select module and inverter blocks to match roof sections, AC service, and the local interconnection design.

Coordinate packing, serial documentation where available, and delivery batches around the construction plan.

Key Benefits

Traceable equipment schedule
A clear BOM helps the buyer, EPC, and receiving team review exactly what is included.
Installation-aware delivery
Packing and shipment can be aligned to work areas or project phases where the order supports it.
Storage-ready discussion
Storage may be evaluated later using actual site loads and interconnection constraints.

Typical Configuration

Commercial PV modules
High-efficiency modules selected against roof area, electrical design, and procurement requirements.
Three-phase string inverters
Multi-MPPT inverters sized by the local design for roof orientation and string arrangement.
Racking interfaces
Roof-specific hardware selected after structural and waterproofing requirements are reviewed locally.
DC / AC BOS
Cables, connectors, isolators, surge protection, monitoring, and labels according to the approved scope.

What we need for a useful RFQ

Load profile
Share peak demand, daytime and evening consumption, and any motor or refrigeration starting loads.
Site conditions
Confirm roof or ground area, electrical supply, installation environment, and available equipment space.
Destination requirements
Provide destination country, grid code or permit requirements where known, requested documents, and delivery target.

Where this package fits

United States
Commercial buyers need equipment traceability and coordination with local-code and contractor requirements.
Philippines
Warehouses and commercial buildings can use daytime load alignment as the starting point for a rooftop RFQ.
Jamaica
Hotels, warehouses, and service properties may start with PV before deciding whether resilience storage is needed.

Procurement and delivery notes

Confirm roof type, layout, structural approval route, grid requirements, and receiving constraints before final BOM release.
Do not assume that a generic certificate or a previous project design satisfies a local permit or utility requirement.
