The AE Solar HORIZON series redefines performance standards through the use of advanced HJT heterojunction cell technology, which effectively combines the advantages of crystalline and thin-film silicon. This innovative solution completely eliminates the problem of the LID effect and significantly minimizes voltage-induced degradation, which translates into a much longer lifespan and stability of energy yields throughout many years of operation. These modules are distinguished by an exceptionally high bifaciality factor, allowing for the efficient generation of additional power also from radiation reflected from the ground, which is crucial in professional ground-mounted installations and on roofs with light-colored coverings. Thanks to an excellent temperature coefficient, HORIZON panels maintain record efficiency even on very hot days, solving the common problem of performance drops during excessive cell heating. This product is dedicated to investors seeking premium-class solutions, for whom the priority is maximizing production from a limited roof area or in difficult lighting conditions. The use of an advanced N-type structure makes this series distance itself from the competition in terms of resistance to micro-cracks and efficiency in diffused light. It is an intelligent choice for modern photovoltaic systems, guaranteeing the highest possible return on investment thanks to the combination of breakthrough semiconductor physics with an exceptionally solid mechanical construction.

What owners get
Performance in the leading segment

The maximum efficiency of 22.86% exceeds all the comparable products mentioned: DAH DHN-72X16/DG(BB) (22.84%), Horay Solar HS 182-144 TC-D Ocean (22.80%), and Talesun TM7G72M (22.80%). Even the lower end of the range (22.08%) places the series above the median for 144-cell TOPCon 590W modules.

The only Tier 1 BNEF manufacturer in Europe with high bankability

BloombergNEF has identified AE Solar as the only European manufacturer with a "High Bankability" rating in 2024 (bankability has increased from 26% in 2023 to 50% in 2024). This means significantly lower counterparty risk for projects financed by European banks compared to manufacturers from Asia without a European headquarters.

30-year linear warranty on the product and its power

The manufacturer offers both a 30-year product warranty and a 30-year power warranty, with more than 87% of the nominal power remaining after 30 years. Peer comparisons of DAH and Talesun products typically offer a 25-year power warranty, which translates to a significantly higher cumulative energy yield over the entire lifespan.

Low temperature coefficient of TOPCon N-type

The temperature coefficient is -0.29%/°C, which is a notable value for N-type TOPCon technology and significantly better than typical PERC modules (-0.35%/°C). When heated to 65°C, the module loses approximately 11.6% of its rated power, compared to ~14.5% in older PERC generation, which directly translates to higher energy yield during the summer season.

Awarded PVEL Top Performer 2025

AE Solar has been awarded the Kiwa PVEL Top Performer Award 2025 for its TOPCon N-type bifacial modules, which is an independent validation of the product's quality and reliability, as demonstrated in rigorous laboratory tests, including resistance to PID degradation, mechanical stress, and thermal cycling.

About the HORIZON series

6 answered

These answers cover the whole series. Where a figure differs, the specification above is this module's own.

What are the key features of the TOPCon technology used in AE Solar HORIZON panels?
TOPCon (Tunnel Oxide Passivated Contact) is a technology for N-type solar cells that, through a tunnel oxide layer, significantly reduces charge carrier recombination. In practice, this translates to module efficiencies exceeding 22%, the absence of LID (light-induced degradation), and exceptionally low annual degradation throughout the product's lifespan. The HORIZON series achieves peak power outputs of up to 590 W, making it one of the most efficient options for residential and commercial installations.
Are AE Solar HORIZON panels bifacial, and under what circumstances does bifaciality actually offer a significant advantage?
Yes, the HORIZON series are bifacial modules - they generate power from both direct sunlight from the front and reflected sunlight from the ground via the back. The additional gain from the back is typically 5-25%, depending on the albedo of the ground and the mounting angle. You will achieve the greatest benefits with ground-mounted systems, flat roofs with a light-colored membrane, or in agrivoltaic systems, where reflection from the ground is high.
What warranty does the AE Solar HORIZON series provide, and what does it cover?
AE Solar provides up to 30 years of product warranty for its HORIZON series, covering manufacturing defects and structural integrity, as well as 30 years of linear power warranty. After three decades of operation, the module should maintain at least 87% of its nominal power. This is one of the longest warranties available in the photovoltaic market, and it reflects the manufacturer's high confidence in the durability of its modules.
How do AE Solar HORIZON panels perform under high temperatures on hot days?
HORIZON modules, based on the N-type TOPCon structure, have a very low temperature coefficient, approximately -0.29%/°C. This means that they lose significantly less power compared to older PERC modules (approximately -0.34%/°C) when the temperature increases above 25°C. When the cell temperature exceeds 60°C in the summer, this difference translates into a significantly higher daily energy yield - particularly important in south-facing rooftop installations that are exposed to intense sunlight.
How many AE Solar HORIZON 590 Wp panels do I need for a 10 kWp residential system?
With a peak power output of 590 Wp per module, you only need approximately 17 panels to build a 10 kWp system. The high power density per square meter, characteristic of N-type TOPCon technology, means that the installation takes up less space on the roof compared to older, less efficient modules. This is a key advantage when roof space is limited or part of the roof is shaded.
Is AE Solar a reputable manufacturer - does it have Tier 1 status?
Yes, AE Solar is a manufacturer with Tier 1 status according to the Bloomberg NEF ranking, based in Germany. This Tier 1 status confirms compliance with strict financial and quality criteria - the modules from this manufacturer are accepted by leading banks and financial institutions that fund photovoltaic projects. This has practical implications when applying for a loan, lease, or funding from programs such as "My Current" or the BGK's green loan program.
