The AIKO Neostar 3N+78 Dual-glass (AIKO-A-MAE78Dw) is designed for investments where the maximum yield per square meter is key - without compromising on longevity. Using n-type cells with back-contact architecture eliminates front-side busbars and improves performance under real-world conditions, including when the module heats up or light is scattered. The dual-glass version is a practical solution for long-term durability - the rear glass supports laminate stability, reduces degradation risks related to moisture, and enhances material fatigue resistance.

For rooftops and complex installations, a major advantage is optimized performance under partial shading, preventing a single shadow from disproportionately blocking the entire module, thus reducing hotspot risks. Additionally, the series focuses on micro-cracking resistance, which is highly valued by installers for transportation and large-scale mounting.

This is an excellent choice for utility-scale solar farms, industry, and commercial applications - where lower BOS costs, stable performance, and high reliability over years are priorities.

What owners get
Efficiency of 24.1–25% – market leader

The series achieves an efficiency of 24.1–25%, exceeding all comparable products in this power range: Luxor HJT (22.74%), Mysolar TOPCon (22.53%), and Sunket (22.5%). The difference of 1.4–2.5% in efficiency translates to a significantly smaller active area needed to achieve the same power output, which directly reduces BOS, installation, and land costs.

Low temperature coefficient of Pmax

The ABC technology provides a power temperature coefficient of -0.26%/°C, compared to the typical -0.29 to -0.32%/°C for TOPCon and HJT. At a module temperature of 70°C, this results in a 1–2% higher yield compared to TOPCon – the cumulative difference over 30 years of operation can amount to several MWh per every 100 kWp installed.

ABC: zero front rails, lower risk of hotspot formation

The All-Back-Contact architecture eliminates the electrode network on the front surface, ensuring 100% active light absorption. The absence of front rails reduces the risk of hotspot formation under partial shading and improves performance with diffuse radiation, which is particularly important in the Central European climate with high cloud cover.

Dual-glass construction with degradation of ≤0.35%/year

The dual-glass enclosure, featuring 2.0+2.0 mm of tempered glass, eliminates the risk of PID degradation and rear film cracking. The manufacturer guarantees ≤1% degradation in the first year and ≤0.35%/year in subsequent years – with a 30-year linear power warranty, this means maintaining at least 87% of the nominal power after 30 years of operation.

BNEF Tier 1, Q1 2026 – fully bankable

AIKO Solar is listed on the BloombergNEF Tier 1 list for Q1 2026, maintaining this status for subsequent quarters. The Tier 1 designation from BNEF is a standard requirement for financial institutions funding PV projects exceeding 1 MW, which removes a barrier for project finance and reduces insurance costs for institutional investors.

Trade-offs
Lack of bifaciality

The series is not bifacial, while a comparable peer product – Luxor ECO LINE HJT 680–700 W – offers a bifacial module in the same power range. In ground-mounted installations with a light-colored substrate or agrivoltaic applications, bifaciality typically provides a 5–15% higher annual yield, which the Neostar 3N+78 cannot offer.

ABC price premium: 10–50% above TOPCon

ABC technology is associated with a 10–15% premium in the commercial C&I segment and up to 50% in the European distributed market compared to comparable TOPCon modules (market data Q1 2026). For projects with ample available space, where surface efficiency is not a critical factor, higher CAPEX can extend the SPBT beyond alternatives based on TOPCon.

The product warranty is only 15 years.

While a 30-year performance warranty is common, the product warranty typically only covers 15 years. Some premium manufacturers in the high-efficiency segment offer 25-year product warranties (e.g., REC Group Alpha Pure-R), which can be a deciding factor in installations in difficult-to-access locations or for long-term service contracts.

Common questions

6 answered
What distinguishes the back contact technology in Aiko Neostar 3N+78 panels from standard PERC cells?
In the back contact (ABC) technology, all electrical contacts are moved to the rear of the cell, eliminating the front grid lines that collect current. This allows for more of the cell's surface to be exposed to light, resulting in an efficiency of approximately 25%. Traditional PERC cells have visible grid lines on the front, which slightly block light and typically limit efficiency to 21-22%. The back contact architecture also improves performance under diffuse light and at higher temperatures.
What is the warranty on the Aiko Neostar 3N+78 Dual-glass solar panels, and for how long will they maintain their performance?
The AIKO Neostar 3N+78 series comes with a 15-year product warranty covering defects and malfunctions, as well as a 30-year performance warranty. The manufacturer guarantees a degradation of no more than 1% in the first year and a maximum of 0.35% per year in subsequent years. This means that after 30 years, the module should retain more than 87% of its nominal power, which is better than the typical PERC modules with a degradation rate of approximately 0.55% per year.
Will the AIKO Neostar 3N+78 solar panels perform adequately in an industrial setting with partial shading?
Yes. The back-contact architecture improves the performance of the module under partial shading – a single shadow does not disproportionately block the entire panel, and the risk of hotspot formation is lower than with modules with front contacts. This is one of the key reasons why this series is recommended for PV farms and large commercial buildings, where roofs often have skylights, chimneys, or antennas that cast shadows.
What advantages does the dual-glass design offer in the AIKO Neostar 3N+78 series, and does the module become heavier as a result, making installation more difficult?
The glass back replaces the standard back sheet and reduces the ingress of moisture into the laminate, which minimizes the risk of PID degradation and corrosion throughout the lifespan. The module is also more resistant to micro-cracks in the cells during transport and installation on large structures. Dual-glass modules are slightly heavier than those with a film, so it is important to ensure that the supporting structure is designed to accommodate their weight before installation.
What is the maximum power output of the Aiko Neostar 3N+78 solar panel, and how does it perform in high temperatures during the summer?
The peak power of the module is 700 Wp. The power coefficient (Pmax) at varying temperatures is -0.26%/°C, which is significantly better than the average PERC cells, where the coefficient typically ranges from -0.35% to -0.40%/°C. When the module is heated to 60°C, the AIKO panel loses proportionally less power than most competing products, resulting in higher energy yield on hot, summer days – which is particularly important in industrial settings.
For which types of investments is the AIKO Neostar 3N+78 Dual-glass series intended, and is AIKO a reliable manufacturer?
Due to its high individual power output (700 Wp) and module dimensions (2465 x 1134 mm), the series is primarily aimed at solar farms, industrial, and commercial installations, where low BOS (Balance of System) costs and maximum energy yield from available space are key considerations. AIKO Solar is a Tier 1 manufacturer based in China, with a presence in Poland through authorized distributors. The Neostar 3N+78 series is currently available and actively being sold.
