Type X AC Solar Module Specifications

What Is an AC Solar Module?

An AC solar module is a solar panel with a microinverter built directly into the panel. Instead of sending DC electricity to a separate central inverter, each module converts electricity into usable AC power as it is generated.

Because every panel operates independently, an AC solar system can continue producing energy efficiently even if one panel is affected by temporary shading, dirt or debris. This panel-level operation also provides greater design flexibility for roofs with multiple orientations and enables more detailed performance monitoring.

Compared with traditional DC solar systems, AC modules can simplify installation by reducing the need for a separate string inverter while making future system expansion easier. These benefits have made AC solar modules an increasingly popular choice for premium residential and commercial solar installations.

What Makes the Type X AC Solar Module Different?

The Type X AC solar module combines several advanced technologies into a single integrated solution, helping installers and system owners achieve high performance with fewer system components.

Factory-Integrated Enphase IQ8HC Microinverter

Every module includes an Enphase IQ8HC microinverter, allowing each panel to convert DC electricity into AC electricity independently. This supports panel-level optimisation, detailed monitoring and simplified system design without requiring a separate string inverter. The Enphase IQ8HC offers a maximum efficiency of 97.4%, helping convert more generated solar energy into usable electricity.

Advanced Type X Cell Technology

The module is built using Type X Back-contact Cell Technology, which places electrical contacts on the rear of the solar cell rather than the front. This increases the active surface area available to capture sunlight while creating a cleaner cell design.

Combined with N-Type cells and 0BB (Zero Busbar) architecture, this advanced design contributes to module efficiencies of up to 24.5%, allowing more power to be generated from the available roof space.

Engineered for Long-Term Reliability

The Type X AC solar module also features a robust dual-glass construction and a bifacial design, helping improve durability while enabling the rear side of the panel to capture reflected sunlight under suitable installation conditions. Together with its low degradation rate and long-term warranty coverage, these features are designed to deliver reliable performance throughout the module's lifespan.

This integrated approach makes the Type X AC solar module more than just a solar panel with a built-in microinverter—it is a complete, high-performance solution designed to support efficient, reliable solar energy systems.

How the Integrated Enphase IQ8HC Microinverter Works

The defining feature of the Type X AC solar module is its factory-integrated Enphase IQ8HC microinverter. Instead of sending direct current (DC) electricity from multiple panels to a central string inverter, each Type X AC module converts DC power into usable alternating current (AC) at the panel itself.

This panel-level conversion allows every module to operate independently. If one panel is affected by temporary shading, dust or debris, the remaining panels continue producing electricity without being limited by the lower-performing module. This approach can improve energy harvest in installations with multiple roof orientations or partial shading.

The integrated Enphase IQ8HC microinverter also offers a maximum efficiency of 97.4%, helping maximise the amount of usable electricity delivered from each panel. Because the microinverter is factory-installed, installers can benefit from a streamlined installation process with fewer major system components.

Advanced Type X Solar Technology

The Type X AC solar module combines advanced photovoltaic technologies to improve efficiency, durability and long-term performance. These technologies work together to maximise energy production while supporting reliable operation in a wide range of environmental conditions.

Type X Back-contact Cell Technology

The module uses Type X Back-contact Cell Technology, which relocates the electrical contacts to the rear of each solar cell. Without metal contacts on the front surface, more sunlight reaches the photovoltaic material, increasing the active area available for energy generation.

This cleaner cell design contributes to higher efficiency while giving the module a more uniform appearance.

N-Type and 0BB Architecture

The Type X AC module is built on N-Type solar cell technology and 0BB (Zero Busbar) architecture.

N-Type cells are recognised for their excellent long-term stability and lower degradation, helping maintain energy production throughout the life of the module. The 0BB design reduces electrical resistance while improving current collection, contributing to the module's high efficiency of up to 24.5%.

Dual-Glass Construction

Instead of using a conventional polymer backsheet, the Type X AC module features a dual-glass construction with tempered front glass and semi-tempered rear glass.

This design improves durability, enhances resistance to moisture and environmental exposure, and provides additional structural strength for long-term performance.

Bifacial Design

The Type X AC module also incorporates a bifacial architecture, enabling the rear side of the panel to capture reflected sunlight when installed in suitable conditions.

With a bifaciality rating of approximately 70 ±5%, the module can generate additional energy beyond front-side production, depending on factors such as mounting height, roof design and surface reflectivity.

System Design Benefits

Integrating the microinverter directly into the solar module offers practical advantages for installers, system designers and property owners.

Simplified Installation

Because every panel includes its own Enphase IQ8HC microinverter, there is no need to install a separate central string inverter. This simplifies system design and reduces the number of major components required.

Panel-Level Optimisation

Each module operates independently, allowing individual panels to perform at their maximum potential. This can improve overall system performance where shading, debris or varying roof orientations affect only part of the array.

Flexible System Design

AC solar modules provide greater flexibility when designing systems across multiple roof sections, making them well suited for residential and commercial projects with more complex roof layouts.

Easier Monitoring and Maintenance

Panel-level monitoring allows individual module performance to be tracked more easily, helping identify issues quickly and simplifying ongoing maintenance.

Future Expansion

Because each module has its own integrated microinverter, expanding an existing AC solar system can be more straightforward than upgrading a traditional string inverter system.

Together, these benefits make the Type X AC solar module a premium solution for projects that prioritise performance, flexibility and long-term reliability.

Long-Term Performance and Warranty

A solar module is a long-term investment, so durability and consistent energy production are just as important as efficiency. The Type X AC solar module is engineered to maintain strong performance over decades of operation, supported by comprehensive warranty coverage.

According to the official REA Power datasheet, the module includes a 25-year product warranty and a 30-year linear performance warranty. Power degradation is limited to 1% in the first year, followed by no more than 0.35% per year from Years 2 to 30. At the end of the warranty period, the module is guaranteed to retain 88.85% of its original power output, providing confidence in its long-term energy production.

Warranty at a Glance

Type X AC Module vs Traditional DC Modules

Both AC and DC solar modules are capable of delivering reliable solar energy, but they differ in how the system is designed and where power conversion takes place.

An AC solar module is often well suited to projects with multiple roof orientations, partial shading or future expansion plans. A traditional DC module may be more appropriate where a central inverter best meets the project's design requirements.
