Project Overview
A recent solar PV installation on a small commercial building presented our team with a unique and complex challenge. The objective was to install 42 solar panels on a roof covered with Britmet Ultratile, a lesser-known lightweight metal tile roofing system. While the technical installation itself was straightforward, the project soon became entangled in a regulatory dilemma involving manufacturer warranties and MCS (Microgeneration Certification Scheme) compliance.
Site Survey and Challenge
During the initial site survey, we identified the roofing material as Britmet Ultratile—an unusual choice for commercial properties and one that limited the compatibility of standard solar mounting systems. Our priority was to ensure that the solar installation did not void the manufacturer’s warranty on the roof.
We reached out directly to Britmet to discuss mounting options that would preserve the warranty. Britmet recommended specific roof hooks manufactured by Renusol, a well-respected name in the solar industry. However, the particular Renusol hooks approved by Britmet for use with their Ultratile system had not yet received MCS certification.
This created a significant dilemma:
- Using the recommended Renusol hooks would preserve the roof warranty but result in the installation not being eligible for an MCS certificate.
- Using an MCS-certified mounting system not approved by Britmet could void the client’s roof warranty—an unacceptable risk for both the client and us.
Client Engagement and Decision
We presented the situation to the client with full transparency. After reviewing the pros and cons, the client made an informed decision to proceed with Britmet’s recommended hooks, prioritising the preservation of the roof warranty over obtaining an MCS certificate.
