Roof and site constraints
Available area, existing penetrations, shade, access, fire routes, roof condition and loading assumptions.
Solar PV / Factory rooftop
Industrial rooftop solar: electrical construction & grid integration
Buildable PV projects depend on safe roof access, validated electrical architecture, grid-interface protection and a clear construction scope—not simply a nominal kWp figure.
Technical scope, construction boundaries and commercial terms confirmed per project.
From usable roof area to an electrical design basis
QuangAnhcons supports industrial rooftop solar work packages, with particular attention to DC/AC electrical installation, inverter interfaces, factory MV/LV integration, protection and commissioning coordination. Structural design, required authorisations and commercial energy assumptions must be assigned to the appropriate qualified parties.
What a rooftop PV RFQ should separate
Array and inverter architecture
Module/string concept, inverter selection, DC/AC cable paths, voltage and collection strategy.
Factory grid connection
Tie-in location, LV/MV capacity, fault/protection coordination, export limits and plant operating profile.
Installation and electrical BoP
Cable routes, containment, DC/AC distribution, earthing and protection installation.
Inspection and testing
Isolation, insulation, continuity, polarity, protections and quality documentation per approved procedure.
BESS and EMS interfaces
Space, metering and control provisions for possible storage or energy management integration.
Decisions that drive PV constructability
Validate roof, utility interface, electrical rooms, cable access and equipment locations.
Align proposed DC kWp and AC kW with load, inverter capacity and roof limitations.
Install to approved design, check interfaces and record quality evidence.
Complete defined tests, protection interface checks and handover documents.
What helps a solar quotation
If sizing from roof area
- Roof drawings, usable roof area and site coordinates.
- Roof material, age, condition and load capacity evidence.
- Obstructions, shading and access constraints.
If sizing from required capacity
- Target DC kWp or AC kW and approximate operating profile.
- 12-month energy data if available and current demand limits.
- Existing transformer, switchgear, protection and metering data.

Clarifying solar scope
Questions often raised during a preliminary engineering and commercial review.
Can the tool estimate installed capacity from roof area?
An indicative tool can derive a capacity range using verified area, packing assumptions and exclusions. Final DC sizing requires a roof survey, structural review and equipment selection.
Is a solar budget quote a generation guarantee?
No. Budget pricing and generation modelling are different deliverables; a formal energy yield study must state its assumptions, weather dataset and loss factors.
Is a BESS included?
Not unless agreed. Storage power, duration, EMS control, fire safety and grid requirements require a separate scope.
Who is responsible for permits and structural adequacy?
These responsibilities are documented in the agreed design and construction scope with the relevant qualified parties.
Request engineering and commercial review
Planning a factory rooftop solar project?
Send the location, technical ratings, SLD or BOQ if available, target dates and expected supply/installation boundaries. The quotation will identify assumptions and exclusions.
