Information about the ASE-300-DG/50


When your photovoltaic system demands a utility-grade module that will deliver 285 watts of power or more, specify the UL-listed ASE-300-DG/50. Designed to meet the rigorous standards of the electric utility industry and the U.S. military where long life, reliable performance and system compatibility are critical, the ASE-300-DG/50 has unrivaled advantages.The ASE-300-DG offers versatility and unprecedented ease of installation for systems above 2kW. Made of 216 crystalline (EFG) silicon cells, each cell measuring 100mm by 100mm, the ASE-300-DG/50 utilizes our advanced proprietary encapsulant (not EVA) to seal the module. Tempered glass on back and front produces a module that is virtually impervious to tear, penetration, and moisture.

 

ASE-300-DG/50 Module Advantage

The design of the ASE-300-DG/50 was driven by both installers and end-users. They wanted:
  • Robust modules to endure the harshest environments.
  • Predictable performance.
  • Certification by recognized U.S. and world standards organizations.
  • Fast, easy installation.
  • High voltage per module.
  • Increased reliability.
  • An encapsulation system to overcome the decline in module performance associated with degradation of traditional EVA encapsulant.
  • Durable construction to protect the module from tear, penetration, fire, electrical conductance, delamination, and moisture.
Installation Advantage

They designed the ASE-300-DG/50 to save time and expense.
  • Large area requires fewer interconnects and structural members.
  • Module-module and source circuit wiring are incorporated in module.
  • Wiring comes neatly clipped inside module frame - no need to secure wiring in the field.
  • Unique two-pin quick-connect reduces source circuit wiring time to minutes.

Quality Advantage

The quality program is focused on meeting or exceeding expected performance and reducing system losses:
  • Each module is individually tested under calibrated solar simulator.
  • Module-module wiring losses are included in the rating.
  • Each of the 216 crystalline silicon cells is inspected and matched according to their power output.
  • For large projects, modules are matched by current to reduce system mismatch losses.

Temperature Effects

The following temperature correction coefficients should be applied to STC data (at 25°C cell temperature) to predict module performance at field conditions:

 

Voc -0.38%/°C
Isc +0.10%/°C
Ppeak -0.47%/°C
Vpeak -0.50%/°C
NOCT 45°C
Greatest Power of Any Model -- Fewest mounting fasteners and external electrical connections per watt of array.

High Efficiency Silicon Solar Cells -- High power per unit area in a long life, stable crystalline solar cell.

High Module Voltage -- Allows integrators to "fine tune" the system by providing just the right number of modules to meet the specified power. Perfect for grid-connected and high voltage battery systems.

Advanced Encapsulant -- Developed by , this encapsulation system has been shown to outperform traditional EVA.

Double Glass Construction -- As a perfect moisture barrier, the glass-on-glass construction provides the longest possible module life.

Internal Bypass Diode Protection -- Bypass diode protection every 18 cells in series.

Quick, Polarized Connectors -- Array module-to-module wiring is a snap (literally!).

Two Conductor Harness -- No traditional return wire is needed from the end of a row back to the source combiner.

Power Testing at the Connector -- Wire loss within the module-to-module wiring is already accounted for at the factory module tester.

UL 1703 Listing -- A world recognized authority on electrical safety. Makes approval a breeze.

Class A Fire Rating -- Permits module mounting on any roof without compromising the roof's fire rating.
