Trinamount is a new solar mounting system that installs faster, with fewer parts and at lower cost than conventional rail-based systems. It uses interlocking components that snap together without tools or measurement, simplifying installation. Each component is self-grounding so grounding is integrated into the system. Installation can be completed in as little as one day compared to three days for rail systems. With fewer SKUs and parts, logistics and warehousing are simpler. The system is designed to be theft-resistant and can accommodate modules in either portrait or landscape orientation for improved efficiency.

3. Conventional Solar Installations Require Railing
Rails are expensive, time-consuming and challenging
It’s time-consuming to manage the
many SKUs and to load parts onto
trucks.
Additionally, rails must be:
• Stored in costly warehouse space
• Cut to meet the requirements of
the individual job
• Carried or crane-hoisted onto the
roof
•Affixed to the roof with an array of
small parts

4. The Challenges of Grounding Conventional Systems
Grounding is difficult and time consuming
• Must ground each module and rail
• Each event takes 5+ minutes
• Often entails grounding “jumpers”
between rails.
• Ground lugs are susceptible to
corrosion, premature failure
• Systems often become improperly
grounded over time

5. Innovative Solar Mounting Solution
• Installs quickly
• Few parts simplify
logistics
• Self-grounding
• Installs portrait or
landscape
