The Story
The Trina Solar Vertex S+ TSM-510NEG18R.28 is a 510W dual-glass N-type i-TOPCon module built on Trina's 210mm cell platform and finished with a black anodized aluminium frame. Sized for the "Golden Size" commercial and industrial rooftop format, it combines a compact 1961 x 1134mm footprint with up to 22.9% module efficiency, making it well suited to C&I roofs, medium-scale ground mount, and any project where high power density and long-term reliability matter more than the lowest unit price. The glass-glass construction improves resistance to micro-cracking and harsh environments, while Trina's i-TOPCon cell technology keeps degradation low across a 30-year linear power warranty.

Dual-glass construction, not glass/backsheet: Trina's official datasheet confirms the TSM-NEG18R.28 series is a monofacial dual-glass module (1.6mm heat-strengthened front and back glass), not a glass/backsheet laminate. Listings referencing a "white backsheet" for this MPN do not match manufacturer specification — please confirm construction type with the customer before dispatch if this distinction matters for their project.
Frame colour code matters when ordering: The .28 suffix denotes the black frame version (TSM-NEG18R.28); the silver frame equivalent is sold under the .20 suffix (TSM-NEG18R.20). Confirm the customer wants the black-frame variant before processing MCS documentation or DNO paperwork, as frame colour is not always visible on a packing list.
Installer safety notice: This module carries a 1500V DC maximum system voltage and must only be installed, wired, and commissioned by an MCS-certified installer in accordance with BS 7671 DC isolation requirements and the manufacturer's installation manual. Always read Trina Solar's safety and installation instructions before handling or connecting this module, and follow standard DNO notification procedures for the completed array.

N-Type i-TOPCon Cell Technology
Trina's i-TOPCon platform reduces contact resistance, boosts rear-side reflection, and repairs edge-quality losses on the cell, pushing module efficiency to 22.9% without increasing the physical footprint — more power per roof square metre.
|
Dual-Glass Reliability
Glass front and back sheets make the module less prone to micro-cracking during handling and installation, and improve resistance to salt mist, ammonia, sand, and high-humidity environments — useful for coastal or agricultural sites.
|
|
Low Degradation, Long Warranty
First-year degradation is capped at 1%, then 0.4% annually, guaranteeing 87.4% of rated output at year 30 — backed by a 15-year product warranty and 30-year linear power warranty.
|
Compact C&I-Optimised Footprint
At 1961 x 1134mm and 23.5kg, this is Trina's "Golden Size" for commercial rooftops — under 2 metres in length for easier handling, with a form factor designed around large-scale roof layouts.
|
|
High Real-World Energy Yield
A low temperature coefficient of -0.29%/°C limits power loss on hot roofs, and the module holds validated low-irradiation performance for stronger output on overcast UK days.
|
Mainstream System Compatibility
Fitted with TS4 / MC4 EVO2-compatible connectors and rated to 1500V DC, the module is designed to work with existing mainstream inverters, optimisers, and mounting systems without special adaptors.

What does "N-type i-TOPCon" mean and how is it different from P-type PERC?
N-type i-TOPCon uses an n-type silicon wafer with a tunnel oxide passivated contact layer, which reduces recombination losses at the cell surface. In practice this means higher efficiency and lower degradation over time compared with older P-type PERC cells, which is why this module can guarantee 87.4% output at year 30 rather than the ~80–83% typical of PERC modules.
What's the difference between the .28 and .20 versions of this MPN?
The suffix denotes frame colour only — TSM-510NEG18R.28 is the black-frame version stocked here; TSM-510NEG18R.20 is the equivalent silver-frame module. Electrical performance and mechanical specification are otherwise identical between the two.
Is this panel suitable for a residential roof, or is it strictly commercial?
It's marketed by Trina primarily for commercial and industrial rooftops due to its "Golden Size" format, but the compact 1961 x 1134mm dimensions and 23.5kg weight also make it workable on larger domestic roofs where fewer, higher-power modules are preferred over a larger count of smaller panels.
What inverters and mounting systems is this module compatible with?
Trina designs the Vertex S+ range for compatibility with mainstream inverters, power optimisers, and mounting systems already on the market, using TS4/MC4 EVO2-compatible connectors and a 1500V DC maximum system voltage. Always confirm string sizing and voltage windows against the specific inverter datasheet before final system design.
Does the dual-glass build make this panel heavier or harder to install than a standard glass/backsheet module?
At 23.5kg for a 1961 x 1134mm module, it's broadly in line with other C&I-format panels of this size. The dual-glass build adds a small amount of weight over a glass/backsheet equivalent but improves resistance to micro-cracking and harsh-environment degradation, which typically offsets the marginal handling difference over the system's lifetime.
What warranty cover does this module carry?
This module carries a 15-year product warranty covering materials and workmanship, and a 30-year linear power warranty guaranteeing at least 87.4% of rated output at year 30, based on 1% first-year degradation and 0.4% annual degradation thereafter.
