01 Roof type Identify roof construction, profile and substrate to set mounting fit and fixing boundaries.
ROOF CONDITION ASSESSMENT
System design starting from roof conditions
Confirm building conditions before array, mounting and fixings. Roof type, structural capacity, local wind climate and existing waterproofing all set the design boundary.
02 Structural loads Use existing structural data and checks to control added dead load and construction-stage effects.
03 Wind loads Check wind loads and design nodes from site location, building height and roof zones.
04 Waterproofing Review membrane type and existing details so structural fixings do not become leakage risks.
ROOF TYPE ADAPTATION
Adaptation across multiple roof types
One node does not cover every roof — choose fixing methods and load paths that match the building construction.
METAL ROOF 01 / METAL
Metal / standing-seam roofs
Match clamps to profile, seam type and purlin conditions; avoid unnecessary roof penetrations.
View installation strategy ↗
CONCRETE ROOF 02 / CONCRETE
Concrete flat roofs
Choose ballast or mechanical fixing from structural capacity, waterproofing and array layout.
View installation strategy ↗
MEMBRANE ROOF 03 / MEMBRANE
Flexible membrane roofs
Protect the membrane, control local loads and wind uplift; keep fixings coordinated with the existing roof system.
View installation strategy ↗
COMPLEX ROOF 04 / COMPLEX
Complex industrial roofs
Resolve conflicts from stepped roofs, dense equipment, skylights and existing services with zoned layout and custom nodes.
View engineering layout ↗SYSTEM ENGINEERING LAYOUT
Rooftop PV system engineering layout
Coordinate arrays, access, fire routes, electrical paths and O&M constraints on one engineering plan — not just fill the roof with modules.

STRUCTURAL RELIABILITY
Safety and structural reliability
Reliability comes from a closed engineering chain: structural inputs, load calculation, node detailing, corrosion protection and site acceptance.
Structural review
Identify structural system and capacity boundary
Wind load calculation
Zone-check system uplift resistance
Node design
Define connections, load transfer and detailing
Corrosion scheme
Match materials to environmental exposure
Install acceptance
Key process checks and quality closeout
INSTALLATION STRATEGY
Installation strategies that protect the roof
“No roof damage” is not an absolute promise for every roof. Choose nodes that balance structural safety, waterproof continuity and constructability for the actual roof build-up.
Clamp fixing
Dedicated clamps grip metal-roof seams without penetrating the roof sheet.
Ballasted
Concrete or steel ballast provides uplift resistance without roof penetrations, protecting the membrane.
Mechanical fixing
Mechanical anchors into concrete structure for reliable connections.
Custom nodes
Custom solutions for special roofs and details with precise adaptation.
Engineering boundary： Final fixing methods must follow existing structural documents, site survey, waterproofing system, load checks and applicable codes.
ENERGY FLOW
From generation to facility energy use
C&I rooftop PV value depends not only on installed capacity, but also on facility load curves, tariff structure, self-consumption ratio and interconnection conditions.
