The Aiko 665W 3N+ Series Bifacial Panel is a bifacial photovoltaic module rated at 665 watts, built around Aiko Solar's N-Type ABC (All Back Contact) cell architecture. By moving every electrical contact to the rear of the cell, the design removes the front-side metal busbars found on conventional panels, increasing the usable light-capturing surface and helping the module reach efficiencies in the mid-20 percent range within Aiko's Stellar and Neostar product families. The N-type silicon base avoids the boron-oxygen defects responsible for light-induced degradation in older P-type cells, so first-year output loss is typically limited to around 1 percent, with subsequent annual degradation held to roughly 0.35 percent under Aiko's published warranty terms.

The Aiko 770W Bifacial Panel is a bifacial photovoltaic module rated at 770 watts, built around Aiko Solar's N-Type ABC (All Back Contact) cell architecture.

The N-type silicon base avoids the boron-oxygen defects responsible for light-induced degradation in older P-type cells, so first-year output loss is typically limited to around 1 percent, with subsequent annual degradation held to roughly 0.35 percent under Aiko's published warranty terms.

The Astronergy 715W Bifacial Solar Panel belongs to Astronergy's ASTRO series of N-Type TOPCon bifacial modules, produced by Astronergy (a subsidiary of the CHINT Group) and rated at 715 watts. TOPCon, short for Tunnel Oxide Passivated Contact, adds an ultra-thin passivation layer to the rear of the cell that reduces electron recombination and lifts both voltage and efficiency compared with standard PERC cells. Depending on the specific ASTRO generation, Astronergy's TOPCon cells are paired with SMBB or zero-busbar (ZBB) ribbon interconnection to improve current collection and reduce microcrack risk, and the series has demonstrated bifaciality figures reported up to around 85 percent in Astronergy's published datasheets.

The Canadian 715W Bifacial Solar Panel is part of Canadian Solar's HiKu bifacial platform, sold under the TOPHiKu6 or TOPBiHiKu7 naming depending on cell format, and rated at 715 watts. These modules use N-type TOPCon cells, which add a passivated rear contact layer to reduce recombination losses versus conventional PERC cells, and Canadian Solar's published datasheets report module efficiencies of up to roughly 23 percent along with power bifaciality figures reaching approximately 85 percent under standard test conditions. The dual-glass bifacial construction lets the rear face generate additional energy from reflected light in appropriately sited installations, such as elevated racking, carports or light-coloured ground cover.

The JA 625W Bifacial Solar Panel is manufactured by JA Solar as part of its DeepBlue 4.0 platform, rated at 625 watts and built on N-type TOPCon half-cut cells using JA Solar's Bycium+ passivation technology. This passivated contact layer raises cell open-circuit voltage and reduces recombination losses compared with earlier P-type PERC designs, and JA Solar's published datasheets report module efficiencies of roughly 22 to 23 percent for this bifacial series, along with bifaciality in the region of 80 percent, meaning the rear face can add meaningfully to total energy yield depending on ground reflectivity and mounting height.

The LONGi Hi-MO X7 620W Bifacial Panel is part of LONGi's Hi-MO X7 series, rated at 620 watts and built on LONGi's HPBC (Hybrid Passivated Back Contact) N-type cell technology. Like other back-contact designs, HPBC relocates the cell's electrical contacts to the rear surface, eliminating visible front-side busbars and giving the module a clean, uniform appearance while increasing the active light-absorbing area. LONGi reports HPBC cell efficiencies exceeding 25.5 percent at the cell level, and the Hi-MO X7 series is offered in bifacial dual-glass configurations that allow the rear surface to capture reflected light in suitably sited installations, adding to the panel's front-side rated output.

The Risen HJT 740W Bifacial Solar Panel uses Risen Energy's heterojunction (HJT) cell technology, rated at 740 watts under the company's Hyper-ion or Titan HJT product lines. HJT cells combine a crystalline silicon wafer with thin layers of amorphous silicon to form the junction, a structure that typically yields a lower temperature coefficient than TOPCon or PERC cells, commonly cited in Risen's literature at around -0.24 to -0.26 percent per degree Celsius, helping the module retain more of its rated output in hot operating conditions. Risen's HJT modules are supplied in bifacial dual-glass format, with published bifaciality figures reaching as high as 90 percent, supporting strong rear-side energy capture in reflective or elevated installations.

The Trina 630W Bifacial Solar Panel is part of Trina Solar's Vertex N series, rated at 630 watts and built on the company's N-type i-TOPCon cell technology. TOPCon cells add a passivated tunnel-oxide layer to the rear contact, cutting recombination losses and lifting efficiency relative to standard PERC cells, and Trina's published datasheets report module efficiencies of up to roughly 23 percent for this bifacial dual-glass series, together with power bifaciality of about 80 percent, meaning the rear face can meaningfully add to total energy yield in ground-mount or elevated installations with reflective surroundings.
