Aiko Neostar 3S+ 540W Bifacial Solar Panel | AIKO-A540-MCE60DB

Description

The Aiko Neostar 3S+ 540W (AIKO-A540-MCE60DB) is a full black, dual-glass, bifacial solar panel built on Aiko's N-type ABC (All Back Contact) cell technology. With every electrical contact moved to the rear of the cell, the front face is a clean, uniform black with no visible busbars or grid lines, while the module still reaches 24.4% efficiency from a standard 1954 × 1134 mm footprint.

2.0 mm coated semi-tempered glass on both the front and the rear protects the 120 cells (6 × 20), and the black anodised frame keeps the finish consistent across the array. A −0.26%/°C power temperature coefficient helps output hold up on hot roofs, three bypass diodes limit the impact of partial shading, and the panel is rated 1500 V DC, Class II with an IP68 junction box for residential and commercial rooftop systems. Backed by a 25-year product warranty and a 30-year linear performance warranty.

Safety and regulatory

PV panels produce live DC voltage whenever light falls on them and cannot be isolated at the module. Installation, string design and grid connection must be carried out by a competent installer in line with BS 7671 (Section 712) and the manufacturer's instructions, with G98 or G99 notification or approval for grid-connected systems. MCS-certified installation is required if you intend to claim Smart Export Guarantee payments. At 27.1 kg and almost 2 m long, each panel needs a two-person lift and work-at-height precautions.

Design checks before ordering

Check that the string's maximum Voc at the lowest site temperature stays within the inverter's maximum input voltage: Voc rises by 0.22% per °C below 25°C, so a panel reaches roughly 49.1 V at −10°C (45.60 V at STC). Compare the inverter MPPT's current rating with the panel's Isc of 14.84 A (15.64 A at BNPI). Confirm that your mounting rails and clamps suit a 30 mm frame depth and that the roof structure can carry 27.1 kg per panel.

Sizing note

Use the 540 W STC rating for kWp system sizing. The 570 W BNPI figure is the rating under bifacial nameplate irradiance; actual rear-side gain depends on mounting height, tilt and surface reflectance, and is typically modest on flush roof installations.

Key Features

N-type ABC cell technology

All Back Contact cells place every contact on the rear, giving a gridless, uniformly black front surface with a premium roof appearance and more active cell area exposed to light.

Dual-glass, bifacial construction

2.0 mm coated semi-tempered glass front and rear improves cell protection and durability, and lets the rear side contribute bifacial energy gain from reflected and diffuse light.

Partial shading optimisation

A 120-cell (6 × 20) layout with three bypass diodes is designed to keep the panel producing when part of it is shaded by chimneys, vents or neighbouring roof lines.

Better temperature performance

A −0.26%/°C Pmax coefficient and 409 W output at NOCT support strong yield in warm conditions, backed by Aiko's high-temperature restriction and micro-crack resistance design.

Long-term warranty and low degradation

≤1% first-year degradation and ≤0.35% per year thereafter, guaranteeing 90.6% output at year 25 and 88.85% at year 30.

Rugged, install-ready build

IP68 junction box, MC4-EVO2A connectors on 4 mm² cables, 5400 Pa front / 2400 Pa rear static load rating, and 35 mm hail at 23 m/s tested.

Frequently Asked Questions

Is the Aiko Neostar 3S+ 540W a full black panel?

Yes. It combines a black anodised aluminium frame with N-type ABC cells that have no front-side busbars or grid lines, giving a uniform black appearance across the whole array.

What does bifacial mean for this panel?

The 2.0 mm rear glass lets the back of the panel capture reflected and diffuse light as well as light from the front. Its 570 W BNPI rating reflects this, but the real gain varies with mounting height, tilt and ground or roof reflectance, so size your system on the 540 W STC rating.

How do I check this panel against my inverter?

Compare the panel's Voc (45.60 V, about 49.1 V at −10°C), Vmp (38.40 V) and Isc (14.84 A, 15.64 A at BNPI) with the inverter's maximum input voltage, MPPT voltage window and maximum input and short-circuit current. The panel itself is rated to 1500 V DC, so the inverter or optimiser is normally the limiting factor. If you use microinverters or optimisers, check their input ratings too.

What are the dimensions and weight?

Each panel measures 1954 × 1134 × 30 mm and weighs 27.1 kg ±3%, roughly 12.2 kg per m² of panel area before mounting hardware. Always confirm roof loading and rail and clamp compatibility for a 30 mm frame with your installer or mounting system supplier.

What warranty does it have?

A 25-year product warranty and a 30-year linear performance warranty. Output is guaranteed to degrade by no more than 1% in year 1 and 0.35% per year after that, which means 90.6% of nameplate power at year 25 and 88.85% at year 30.

Which connectors and cables are fitted?

MC4-EVO2A connectors on pre-fitted 4 mm² cables of about 1200 mm, connected to an IP68 junction box with three bypass diodes, so standard MC4-compatible DC cabling and extensions can be used.
