Understanding MCS 012 v3.0: What Installers Need to Know
1. Introduction to MCS 012 v3.0
The Microgeneration Certification Scheme (MCS) has released version 3.0 of the MCS 012 standard, marking a significant shift in the certification requirements for solar mounting systems. This update aims to enhance the safety, reliability, and performance of solar installations, particularly focusing on flat roof systems.
2. Inclusion of Flat Roof Systems
Previously, MCS 012 primarily addressed pitched roof systems. The new version expands its scope to include:
- Mechanically Attached Systems: These involve physical attachments to the roof structure, ensuring stability and resistance to environmental factors.
- Non-Mechanically Attached Systems: These systems rely on weight or adhesive methods for stability, offering alternative solutions for certain building types.
This inclusion ensures that a broader range of mounting systems meet standardized safety and performance criteria.
3. Impact on Clause 5.5.5
Clause 5.5.5 of the MIS 3002 standard previously allowed installers to use non-certified mounting systems for flat roofs, provided they met specific requirements. With the introduction of MCS 012 v3.0, this clause is no longer an acceptable means of compliance. Installers must now use systems certified under the updated MCS 012 standard.
4. Grace Period Details
- Duration: Until August 10, 2025
- Conditions: Installers may register installations using uncertified mounting systems if Clause 5.5.5 conditions are met.
- For Withdrawn Certifications: Products purchased before May 10, 2025, may still be installed and commissioned within six months. Certificates must be issued on or before November 10, 2025.
After November 10, 2025, affected products will no longer be listed in the MCS database for new certifications.
5. Affected Manufacturers
Manufacturers impacted by certification withdrawals include:
- Alumero
- Clenergy
- K2 Mounting Systems
- Henan Tianfon New Energy Tech. Co., Ltd
- Solar Slate Plate
- Wagner
- Fastensol
- dsnewenergy.en.made-in-china.com
- spssolarsolutions.com.au
- pveurope.eu
- Solar Power World
Installers should verify certification status and act within the grace period to maintain compliance.
6. Installer Action Plan
- Audit Current Inventory
- Update Installation Practices
- Maintain Documentation
- Consult MCS Resources
7. Conclusion
The update to MCS 012 v3.0 represents a major step forward in standardizing flat roof solar installations. Installers must adapt to maintain compliance, ensure safety, and deliver quality. Utilizing the grace period and switching to certified systems is key.
