Photovoltaic Module

High-output solar modules for distributed rooftops, commercial arrays and utility projects. Configure cell technology, power class, glass structure, appearance and electrical characteristics around your target market and system design.

450–700+ W* N-type Options* Mono / Bifacial* OEM Available
Request Module Configuration  →

Module-only product: inverter, battery, BMS, EMS, combiner equipment and backup functionality are not included. *Market-reference product classes; final CASSKY model data require confirmation.

Power-generating module, not energy storage

A photovoltaic module converts sunlight into DC electricity. It does not store energy, create AC output or provide backup power by itself. Module selection must therefore focus on electrical, mechanical and environmental compatibility.

MODULE ANATOMY

Engineered as a sealed electrical laminate

Photovoltaic Module Anatomy Solar glass* Cell circuit* Encapsulant* Junction box*
01

Front glass

Tempered coated solar glass protects the cells while transmitting irradiance into the laminate.

02

Cell circuit

Interconnected crystalline-silicon cells generate DC power. Cell technology and circuit layout are model-specific.

03

Encapsulation & rear layer

Encapsulant and backsheet or rear glass isolate the cell circuit from moisture and mechanical exposure.

04

Frame & junction box

The frame supports mounting while the junction box, bypass diodes, cables and connectors carry module output.

*Construction varies by model. Glass thickness, encapsulant, backsheet, rear glass, cell type, frame profile, junction box and connector must match the approved bill of materials and certification.

Select the module architecture

The highest wattage is not automatically the best project choice. Match the module format to roof handling, tracker geometry, rear irradiance, inverter current and logistics.

01 / CELL TECHNOLOGY
N

N-type & advanced cell options

Evaluate TOPCon, back-contact or other model-specific architectures using confirmed efficiency, degradation and temperature data.

  • Module efficiency
  • Power temperature coefficient
  • Initial and annual degradation
02 / REAR CONSTRUCTION
2×

Monofacial or bifacial

Monofacial modules use front-side generation, while bifacial models can harvest rear irradiance when system geometry supports it.

  • Glass-backsheet or dual-glass
  • Bifaciality factor
  • Albedo and mounting clearance
03 / PROJECT FORMAT
W

Rooftop or utility format

Compact formats simplify rooftop handling; larger high-power formats can reduce module count in commercial and utility fields.

  • Dimensions and weight
  • Pallet and container quantity
  • Mounting and tracker compatibility
Compare exact model datasheets Marketing family names do not replace Pmax, Voc, Isc, Vmp, Imp, dimensions and certification-model matching.
Confirm the project operating case Use local minimum temperature, maximum cell temperature, irradiance and inverter limits for electrical design.

Design with voltage and current

Module wattage is only the starting point. A safe string design checks cold-condition open-circuit voltage, hot-condition operating voltage, input current, connector compatibility and local electrical rules.

STEP 01
Voc

Check cold voltage

Correct module Voc for the project minimum temperature before defining the maximum modules per string.

STEP 02
Vmp

Check the MPPT window

Confirm that hot-condition string operating voltage remains inside the inverter MPPT range.

STEP 03
Isc

Check input current

Apply the required design factors to short-circuit current and parallel-string current.

STEP 04
DC

Confirm BOS compatibility

Match cables, connectors, fuses, isolators, combiner equipment, mounting and grounding provisions.

Climate data Minimum ambient and maximum cell temperature
Inverter limits Maximum DC voltage, MPPT range and input current
Array layout Orientation, shading, mismatch and cable routing
Compliance Applicable code, grounding and rapid-shutdown rules
Engineering note: do not publish a universal string length or inverter match on the product page. It changes with the exact module, inverter, site temperature and electrical code.
