What is the difference between Vertex and Vertex S+?
They are families with different references and formats. A valid comparison uses the full code and current datasheets, not only the commercial name.

Trina Solar modules for professionals
Trina Solar modules for residential, commercial and industrial installations, selected by reference, architecture, format, electrical design and mechanical requirements.
View catalogueTechnical FAQHow to choose the right Trina reference
The published range includes different formats and power classes for residential roofs, C&I and larger projects. Selection uses the exact datasheet, not historical family data.
Vertex, Vertex S+ and monofacial or bifacial variants group different references. Cell technology, glass, dimensions, current, connectors, loads and warranty must be checked for the exact SKU.
Criteria to verify
- Full reference and current datasheet review.
- Voc, Isc, thermal coefficients and inverter limits.
- Format, weight, glass and site handling.
- Bifaciality, albedo, height and spacing where applicable.
- Loads, mounting and authorised fixing zones.
- Warranty, connectors and market requirements.
Formats for each project
Residential roof
Format, aesthetics, weight, roof layout and electrical compatibility are prioritised.
Commercial and industrial
Power per area, current, strings, mounting, logistics and maintenance are reviewed.
Large format and bifacial
Rear-side yield depends on design, albedo and geometry; a generic percentage must not be added.
Published professional range
The published range covers references in different power classes. Confirm version, connectors and documentation before comparison or quotation.

Frequently asked technical questions
When does a bifacial module make sense?
When the rear receives useful irradiance and design accounts for albedo, height, spacing, shade and mounting. Yield must be modelled for the site.
How is the string validated?
Using Voc at minimum temperature, Isc, module count, MPPT limits, input current and site conditions.
Can one reference be replaced by another with similar power?
Not without checking dimensions, voltage, current, connectors, loads, fixing zones, glass, weight and warranty terms.
What must be confirmed for the warranty?
Reference, country, date, current documentation and compliance with installation, handling, registration and maintenance requirements.
