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.

πŸ‡―πŸ‡΅

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.

πŸ‡ΊπŸ‡Έ

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.

πŸ‡ͺπŸ‡Ί

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.

01
1

Project Data

You provide project location, terrain conditions, system configuration, and module specifications. Our platform determines the applicable design parameters.

02
2

Load Determination

The platform calculates site-specific environmental loads β€” wind pressure, snow depth, seismic coefficients β€” referencing the applicable standard clauses automatically.

03
3

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.

04
4

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.

Frequently Asked Questions

Compliance support availability depends on project scope and requirements. For standard product orders, we provide general engineering guidance. For projects requiring full structural compliance reports, contact our engineering team to discuss your specific needs.
Typical turnaround is 5–7 business days after receiving complete project data. Complex or large-scale projects may require additional time. We confirm the delivery timeline when scoping each project.
Yes. Our reports include the complete calculation chain β€” environmental loads, member verification with utilization ratios, and safety factor summaries β€” formatted for permit submission. The applicable standard (JIS, ASCE 7, or Eurocode) is referenced throughout.
We need: project location (for wind/snow/seismic zone determination), terrain category, system configuration (tilt angle, row spacing, module specs), and the applicable design standard. Our team will follow up if additional details are needed.
Absolutely. Our platform includes a dedicated SAP2000 comparison module. All calculation results can be independently cross-verified using SAP2000 or equivalent structural analysis software. We provide the input parameters and load cases for third-party review.
No. Our platform was built specifically to make structural compliance accessible for projects of any size β€” from residential installations to utility-scale arrays. Every installation deserves proper engineering.
Use JIS C 8955 for projects in Japan, ASCE 7-16 for projects in the United States and regions referencing IBC, and Eurocode EN 1991 for European projects. Our engineering team can advise on the correct standard for your specific location.
We provide complete structural calculation reports with all engineering data. For projects requiring a licensed Professional Engineer (PE) stamp, we can coordinate with our network of licensed engineers in the applicable jurisdiction.
