Introducing the new Aiko Neostar 3S solar panel: a new definition of plugin solar kit

As a first in Europe, Robinsun introduces the most advanced solar panel on the market into plugin solar kits: the Aiko Neostar 3S series. Long anticipated, these most advanced solar panels are finally available to plugin customers in Robinsun’s entire solar kit range from 1 to 8 panels.

Our community loved the Aiko Neostar 2 series. The full black design and many reports of real production over the Wp levels made good on the promise of much higher solar yields despite Aiko’s higher price point. Now we’re raising the bar again with the new Aiko Neostar 3S solar panel: the most efficient panel we’ve ever offered for plug-in solar kits.We launch a Full Black 475 Wp version of the Neostar 3S, with a module efficiency of 24.5%.

What is the Aiko Neostar 3S solar panel?

The Aiko Neostar 3S is a premium N-type ABC (All Back Contact) monofacial module, designed for residential installations where space, performance and aesthetics all matter.

• In our kits we use the 475 Wp Full Black version
  
• High power in a compact format
  
• All-black front with no visible busbars
  
• Outstanding long-term reliability (25-year product, 30-year performance guarantee)
  
• It’s the panel we choose for customers who want the best possible module on a plug-in solar kit.
  

Why the Aiko Neostar 3S stands out

Seven reasons make the Aiko Neostar 3S ABC 475 Wp different from a “standard” panel:

• Class-leading efficiency: up to 24.5 % module efficiency and power up to 490 Wp in the 3S54 series.
  
• More energy with shade: around 30 % more output than TOPCon when one cell is fully shaded, according to AIKO’s own comparison tests.
  
• Better performance in the heat: excellent temperature coefficient of -0.26 %/°C for Pmax, so it keeps producing when roofs and balconies get hot.
  
• True Full Black aesthetics: real, uninterrupted black surface thanks to ABC (no silver lines on the front).
  
• Stronger and safer: hail tested with 40 mm ice balls at 23 m/s, front load 5400 Pa, back load 2400 Pa and operating range from -40 °C to +85 °C.
  
• Ultra-low degradation: ≤1 % in year 1 and ≤0.35 % per year from year 2 to 30, with 88.85 % power guaranteed at year 30.
  
• Proven technology: AIKO leads global efficiency rankings and invests heavily in R&D, positioning Neostar 3S as the “no-compromise” option in their residential range.
  

Maximum power in the same footprint

With Aiko’s Neostar 3S series you don’t need more space to get more energy: you get more watts out of the same panel size.

• A 3S module delivers up to +25 W more than comparable TOPCon modules with the same dimensions.
  
• In practice, this means higher annual production and better savings from the same balcony, terrace or roof surface.
  

If you already have a plug-in solar kit and want to upgrade, the Aiko Neostar 3S is one of the most effective ways to boost output without changing your available area.

Designed for shade and real-world conditions

Urban installations rarely have perfect, all-day sun. That’s where the Aiko Neostar 3S shines.

• Its ABC cell layout is optimised so the panel keeps working efficiently even with partial shading (railings, chimneys, trees, neighbours’ buildings…).
  
• The improved temperature behaviour means you lose less production on hot summer days, precisely when solar potential is highest.
  

The result: more usable kWh per year in the conditions that actually matter – not just in the lab.

Built to last for decades

The Aiko Neostar 3S is made for long-term residential use:

• 3.2 mm tempered glass and an anodised aluminium frame
  
• IP68 junction box and original MC4 connectors
  
• Hail, mechanical load and fire-safety testing to demanding international standards
  

On top of that, AIKO backs the module with:

• 25-year product warranty
  
• 30-year performance warranty with 88.85 % power guaranteed at year 30
  

That combination of build quality and guarantees makes Neostar 3S an excellent match for customers thinking on a 20–30-year horizon.

True Full Black aesthetics

Because all electrical contacts are moved to the rear (All Back Contact), the front of the Aiko Neostar 3S is a continuous black surface. No silver busbars, no visual noise.

This matters if you:

• Install on a visible balcony or façade
  
• Want a clean look on your roof
  
• Live in a community where aesthetics are important
  

In short: maximum performance without compromising design.
