The Aiko Neostar 3P+ 545W Dual Glass Black White (model AIKO-A545-MCE60Dw) is a third-generation N-Type ABC (All Back Contact) bifacial solar panel built around Aiko's Infinite Technology cell platform. Relocating every electrical contact to the rear of the cell removes front-side busbars entirely, pushing module efficiency to 24.6% at STC — among the highest available for a 60-cell residential-format module. This traceable panel carries individual production and quality traceability records back to cell and wafer level, giving installers and end-customers verifiable provenance for every unit. Finished with a black anodised frame and a lighter white rear-glass panel face (denoted by the "w" suffix), it combines a distinctive two-tone look with genuine bifacial rear-side energy capture. Backed by a 15-year product warranty (extendable to 25 years) and a 30-year linear performance warranty, it is engineered for installers chasing maximum power density per roof area.

Construction
Confirmed bifacial rear-side power gain
Unlike some Aiko dual-glass modules, Aiko's manufacturer datasheet for this AIKO-A-MCE60Dw series publishes a full backside power gain table. At 5% rear irradiance gain, this 545W panel outputs 572W; at 10% gain, output rises to 600W. Real-world gain depends on ground reflectivity, mounting height, and tilt — light-coloured roofing membranes, white ballast trays, or elevated ground-mount frames maximise the effect.
Product warranty term is shorter than the 2S+ dual-glass sibling
This third-generation 3P+ series carries a 15-year product warranty, extendable to 25 years — not the flat 25-year product warranty seen on Aiko's second-generation Neostar 2S+ modules. The 30-year performance warranty is unchanged across both generations. Confirm the extension terms with your Aiko distributor before quoting a 25-year product warranty to a customer.
Installer requirement
Must be installed by an MCS-accredited installer. UK grid-connected PV requires MCS certification for DNO notification compliance and Smart Export Guarantee (SEG) eligibility.
Key Features
Zero front-grid shading loss
With every electrical contact on the rear of the cell, there are no metal busbars on the sun-facing surface to block incoming light or create hotspots — the full front face remains active photovoltaic material.
Full traceability from cell to finished module
As a traceable production batch, each panel's manufacturing history — including wafer and cell origin — can be verified, supporting supply-chain due diligence and quality assurance requirements for commercial and public-sector projects.
Confirmed bifacial rear-side gain
Backed by a published backside power gain table, this panel delivers up to 600W (10% gain) or 572W (5% gain) depending on installation conditions, giving installers a documented basis for system yield modelling rather than an estimate.
Partial shading optimisation
Aiko's ABC cell design includes built-in shade tolerance, helping the module retain a higher share of its output when part of the array is shaded by chimneys, vent pipes, or overhanging branches.
Dual-glass rigidity and longevity
The 2.0 + 2.0mm coated semi-tempered glass sandwich replaces a conventional polymer backsheet, giving superior resistance to moisture ingress, UV degradation, and mechanical flex over a multi-decade service life.
Industrial hail and load rating
Certified to withstand 35mm diameter hail at 23m/s and rated for 5400Pa front / 2400Pa rear static loading, giving confidence for exposed or high-altitude UK installations.

Frequently Asked Questions
What does the bifacial rear-side power gain actually mean in practice?
It means the panel's rear glass surface captures reflected light in addition to direct front-side sunlight. Aiko's datasheet documents this at two test levels: 5% rear irradiance gain (572W) and 10% rear irradiance gain (600W). The gain achieved on any given roof depends heavily on surface reflectivity and mounting height — a white membrane roof or elevated ground-mount frame will produce more gain than a dark, close-mounted roof.
What does "traceable" mean for this panel, and why does it matter?
Traceable production means each module's manufacturing record — including cell and wafer batch origin — can be verified after the fact. This supports supply-chain due diligence requirements increasingly requested on commercial, public-sector, and export-financed solar projects, and gives installers a documented paper trail if a warranty claim needs investigating.
Why is the product warranty only 15 years when other Aiko panels offer 25?
This third-generation 3P+ series ships with a base 15-year product warranty, which Aiko states is extendable to 25 years. This differs from Aiko's second-generation Neostar 2S+ series, which carries a flat 25-year product warranty as standard. The 30-year performance warranty is identical across both generations. Confirm extension terms and any registration requirements with your Aiko distributor before quoting.
Does this panel require an MCS-accredited installer in the UK?
Yes. For UK grid-connected residential and commercial PV installations, the installation must be carried out by an MCS-accredited installer to remain compliant with DNO notification requirements and to qualify for Smart Export Guarantee (SEG) payments.
What is the difference between the black-white (Dw) finish and an all-black (Db) panel?
The "w" suffix denotes a white rear-glass finish rather than the fully blacked-out rear seen on "b"-suffix panels. This two-tone black-front, white-rear appearance is common on bifacial modules, as a lighter rear surface can also assist with thermal performance, though the front-facing appearance from ground level is unaffected.
What connector type does this panel use, and is it compatible with standard MC4?
The panel is fitted with MC4-EVO2A connectors, which are mechanically and electrically compatible with the standard MC4 connector ecosystem used across most UK string inverters and extension cabling, while offering an improved sealing and locking mechanism.
