STRUCTURAL ENGINEERING
Project-Specific Structural Calculations for Solar Mounting
Every installation deserves proper engineering. Our in-house FEM platform generates structural compliance reports for JIS, ASCE 7, and Eurocode β for any project, regardless of size.

Why Structural Compliance Matters
Building permit requirements are tightening worldwide. More jurisdictions now require project-specific structural calculations before approving solar installations β generic load tables are no longer sufficient.
Most installers and EPCs lack the structural engineering resources to produce these calculations in-house. Hiring an external engineer adds cost, time, and coordination overhead to every project.
We built our compliance platform to solve this. As a manufacturer with 15 years of structural engineering experience, we provide what most competitors cannot β project-specific load calculations included with your mounting system.
Permits increasingly require project-specific calculations
External structural engineers are costly and slow
Most mounting suppliers don't offer this capability
Megawa includes engineering support with the product
A Complete Structural Analysis Platform
Built in-house. Not outsourced. Not a spreadsheet.
Load Calculation
Wind, snow, seismic, and dead load calculations with parametric input. Automatically references standard clauses β ASCE 7-16 Β§29.4.4, JIS C 8955 Β§6, or EN 1991-1-4.
FEM Analysis
Three-step progressive analysis: rail verification β frame modeling with support optimization β full 3D frame analysis. Bending, shear, and M-V interaction checks with utilization ratios.
3D Visualization
Isometric model preview with load case switching. Visualize structural behavior under different loading conditions before finalizing the design.
SAP2000 Cross-Verification
Dedicated comparison tab for cross-checking results against SAP2000 β the industry-standard structural analysis software. Full audit trail for engineering review.

Three Standards. One Platform.
Our platform covers the major international standards for solar mounting structural design. Select the standard that applies to your project location.
JIS C 8955
Japan
Japanese Industrial Standard for design loads on structures supporting PV arrays. Covers seismic loads (horizontal and vertical components), typhoon-class wind loads (design wind speeds up to 60 m/s), and snow accumulation. Required for all solar installations in Japan.
Load Types
Seismic, Typhoon Wind, Snow, Dead Load
Required for Japanese building permit applications and FIT/FIP qualification.
ASCE 7-16
Americas
American Society of Civil Engineers standard for minimum design loads and associated criteria. Covers wind loads (component and cladding method, Β§29.4), snow loads (including drift and unbalanced), and seismic provisions (Seismic Design Category). Project-specific parameters derived from ASCE 7 Hazard Tool.
Load Types
Wind, Snow, Seismic, Rain, Dead Load
Referenced by IBC and most US building codes for structural design.
Eurocode EN 1991
Europe
European standard for actions on structures. Wind actions (EN 1991-1-4), snow loads (EN 1991-1-3), and load combinations (EN 1990). National Annexes applied for country-specific parameters including terrain categories, reference wind velocities, and snow zones.
Load Types
Wind, Snow, Combinations, Dead Load
Applicable across all EU member states with National Annex adjustments.
From Project Data to Verified Results
Our engineering workflow follows a systematic, verifiable process.
Project Data
You provide project location, terrain conditions, system configuration, and module specifications. Our platform determines the applicable design parameters.
Load Determination
The platform calculates site-specific environmental loads β wind pressure, snow depth, seismic coefficients β referencing the applicable standard clauses automatically.
Rail & Frame Analysis
Progressive structural analysis: rail verification first, then frame modeling with support optimization. The system checks bending, shear, and interaction criteria at each stage.
3D Verification
Full 3D frame analysis with isometric visualization. Demand vs. capacity checks for every member, with utilization ratios and PASS/FAIL verification for each criterion.
Report & Delivery
Complete structural compliance report generated with all calculations, load diagrams, and verification summaries. Ready for building permit submission.

Engineering Reports You Can Submit
Every report includes the complete calculation chain β from environmental loads to member verification β suitable for permit applications.
- Environmental load calculations with standard clause references
- Member verification: bending, shear, M-V interaction (Demand vs. Capacity)
- Utilization ratios and safety factor summaries
- 3D frame analysis results with force diagrams
- Base reactions for foundation design
- SAP2000 cross-verification data
- Material specifications and product model references
