What differentiates the Trina references in the catalogue?
Format, power, finish, construction, electrical parameters and mechanical conditions vary. Always compare the full code and its current data sheet.

How to choose a Trina panel for each project
The Trina catalogue includes references with different formats, power ratings, finishes and configurations. Professional selection must start from the full code and review dimensions, weight, Vmpp, Voc, Impp, Isc, temperature coefficients, loads, clamping zones, connectors, strings, mounting, documentation and logistics.

Are two Trina panels with similar power interchangeable?
It must not be assumed. Dimensions, voltage, current, connectors, clamping zones, bifaciality and warranty conditions may differ.
How is a string designed with Trina modules?
Using temperature-corrected Voc and Vmpp, Impp and Isc, inverter voltage and current limits, MPPT window and site extremes.
Does bifaciality guarantee a specific gain?
No. It depends on albedo, height, spacing, rear shading, mounting, geometry and actual array operation.
What must be checked when using higher-current modules?
Input and MPPT current limits, parallel strings, connectors, cabling, protection and margins defined by the inverter manufacturer.
What data does PnP need to recommend a Trina reference?
Application, area, location, target power, inverter, string design, mounting, dimension or weight limits, finish, logistics and lead time.
Validate the Trina reference before finalising the quote
We help cross-check the data sheet, strings, inverter, mounting, loads and logistics.
