Back contact module procurement

Back Contact Solar Modules for Model Comparison and Project RFQs

Compare 11 displayed back contact solar module pages covering 465 W to 660 W families and several cell counts, dimensions, construction codes, and appearance variants. Use the exact model page to review electrical data, temperature coefficients, size, mass, glass and frame details, junction box, connector, load references, packing, and available documents before selection.

Displayed model range

Narrow the shortlist by module format and exact variant

The current catalogue forms four practical size groups. These are discovery summaries from the displayed model data, not proof that models with the same dimensions, power, suffix, or cell count are interchangeable or currently available.

96-cell compact format · 465–485 W

One 1762 × 1134 × 30 mm family page at 24.6 kg. Use its full B96EDD model code and exact electrical table rather than comparing only the upper power bin.

108-cell format · 470–500 W

Four 1800 × 1134 × 30 mm family pages with DDD, DSS, and FB variants and displayed masses from 21.6 to 25 kg. Construction and appearance require exact-model review.

120-cell format · 535–560 W

Four 1990 × 1134 × 30 mm pages with DDD, DSS, Black, and standard variants and displayed masses of 23.5 or 27.5 kg, subject to the source tolerance where stated.

Large format · 635–660 W

Two 2382 × 1134 × 30 mm pages at 32.5 kg with 132-cell EDD and 144-cell DDD identifiers. Cell count and construction code must remain tied to the offered model.

Technical shortlist

Six checks beyond the back contact technology name

A rear-contact cell layout is one product characteristic. It does not by itself define the finished module's appearance, power, efficiency, bifacial behavior, glass stack, electrical limits, mechanical suitability, warranty, certification, or destination acceptance.

Cell route and full model code

Keep the complete B96, B108, B120, B132, or B144 identifier and DDD, DSS, EDD, FB, or Black suffix. Do not decode or substitute a suffix without model documentation.

Power, efficiency and test basis

Compare the offered power bin and efficiency under the stated test conditions. Similar nameplate power can sit in a different module area, cell count, or construction.

Voc, Vmp, Isc, Imp and temperature

Use the exact electrical table, temperature coefficients, site temperature range, string length, parallel strings, and inverter limits in the responsible designer's calculations.

Dimensions, mass and mounting

Match length, width, thickness, mass, frame, clamp guidance, cable, connector, handling, and permitted loads to the racking and installation plan.

Front appearance and module build

Confirm front-side appearance, cell layout, glass-glass or glass-backsheet build, rear-side behavior, frame color, junction box, and connector for the exact variant.

Documents, packing and order control

Request the model-matched datasheet, certificates, warranty, installation and load guidance, packing data, labels, and written substitution process before order approval.

Evidence boundaries

Separate cell architecture, finished-module claims, and order status

The current source data contains several model families and suffixes. A reliable shortlist preserves those distinctions and requires every performance, construction, appearance, compliance, and commercial statement to follow the exact quoted model.

Rear contact is not one appearance specification

Back contact describes cell-side conductor placement; verify the finished module's front appearance, cell spacing, frame color, glass, and any Black or FB designation separately.

Bifacial status is not universal

Do not transfer a bifacial statement or rear-side parameter between DDD, DSS, EDD, FB, Black, or other variants. Use the exact model datasheet and test basis.

Loads and certificates stay in scope

A load value, fire class, IEC reference, certificate, test report, or warranty applies only to its stated model, construction, conditions, issuer, revision, and validity.

Catalogue is not a supply promise

Displayed pages do not imply price, stock, MOQ, lead time, production allocation, approved substitution, or shipment readiness; confirm these in the quotation.

Continue the project review

Use the solution page to define the project context, then use the buyer guide to check the exact electrical, mechanical, document, and order fields on the offered datasheet.

Commercial rooftop solar solution

Review how module format connects with roof conditions, array layout, inverter selection, mounting, protection, approvals, logistics, and project responsibilities.

Review solution context

How to read a solar module datasheet

Check full model identity, power bin, electrical values, temperature coefficients, dimensions, mass, connectors, loads, certificates, warranty, and packing before ordering.

Read the buyer guide

Compare the displayed back contact module models

Open the exact family page to review its power bins, electrical table, mechanical data, construction and available file. Keep the complete model code and suffix in the RFQ and approval record.
