690–730W Solar Panel – Monocrystalline TopCon · BE690-730T9-132(HC)
High-efficiency N-Type TopCon monocrystalline solar panel with 425–445W output and 108 half-cut cells. Designed for residential and commercial photovoltaic installations with maximum performance and low degradation.
Overview
Bexie Energy’s BE425-445T8-108(HC) TopCon monocrystalline solar panel is a high-efficiency N-Type photovoltaic module designed for residential and industrial self-consumption installations where maximum output and minimum degradation over time are essential. With power ratings of 425 to 445W and 108 half-cut cells, the TopCon monocrystalline solar panel delivers superior performance to PERC under all operating conditions.
The TopCon technology (Tunnel Oxide Passivated Contact) of the TopCon monocrystalline solar panel reduces recombination losses in the solar cell, achieving higher conversion efficiencies and minimal degradation that guarantees output throughout the entire lifespan of the installation.

Advantages of the TopCon monocrystalline solar panel over PERC
The TopCon monocrystalline solar panel outperforms conventional PERC in the parameters that matter most to the end user:
- Higher conversion efficiency per cell — more kWh per m² installed
- Lower initial degradation (LID) and long-term degradation (LeTID)
- Better performance under high temperatures — fewer losses in summer
- Higher output on cloudy days thanks to sensitivity to diffuse light
- Longer module lifespan — more total kWh generated over 25 years
- More favourable temperature coefficient than PERC
Advantages of the 108 half-cut cell format
The TopCon monocrystalline solar panel with 108 half-cut cells offers a compact and manageable format with high performance:
- Dimensions of 1722x1134mm — easy to handle and install
- Reduced internal resistance thanks to the half-cut design
- Greater tolerance to partial shading than full-cell modules
- Lower module heating during operation
- Greater long-term reliability
Applications of the TopCon monocrystalline solar panel 445W
The TopCon monocrystalline solar panel is suitable for all types of photovoltaic installations:
- Residential solar self-consumption on pitched or flat roofs
- Installations on roofs with limited space
- Industrial and commercial roofs
- Small and medium-scale ground-mount installations
- Pergolas and building-integrated photovoltaic (BIPV) structures
- Residential self-consumption solar kits
Monofacial vs bifacial — which one to choose?
The BE425-445T8-108(HC) TopCon monocrystalline solar panel is the monofacial version in the catalogue, generating energy exclusively from its front side. It’s the most suitable option when:
- The installation is on a pitched roof flush with the roofing — with no space for rear reflected light
- The lowest initial cost per Wp is the priority
- The installation surface has a low albedo
For ground-mount installations or elevated flat roofs where bifaciality adds value, take a look at the bifacial version BE425-445T8-108(HC)BF.
Performance of the TopCon monocrystalline solar panel under real-world conditions
On south-facing installations with a 30-35° tilt in southern Europe, the 445W TopCon monocrystalline solar panel can generate between 440 and 490 kWh per year per installed panel, depending on the geographical area and local conditions.
This translates into average savings of between 65 and 80 euros per year per panel at current energy prices. You can calculate the estimated production for your location using the European Commission’s PVGIS portal.
Integration with the complete PV system
The TopCon monocrystalline solar panel can be combined with our hybrid inverters, LFP storage batteries and mounting structures for a complete residential self-consumption installation. Take a look at the rest of the Bexie solar panel catalogue to compare models.
Frequently asked questions about the TopCon monocrystalline solar panel 445W
What’s the difference between the BE425-445T8-108(HC) and the BE425-445T8-108(HC)BF?
The difference is bifaciality. The model without BF (this one) is monofacial and generates energy only from the front side. The BF model is bifacial and generates energy from the back side as well, which can increase output by up to 25% in installations where light reaches the rear of the panel.
How many panels do I need for a 5 kWp installation?
With this 445W module, you would need approximately 12 panels to reach 5.3 kWp. This takes up around 23 m² of roof surface.
Why is the TopCon monocrystalline solar panel better than PERC?
N-Type TopCon technology reduces recombination losses in the cell, which translates into higher efficiency, lower annual degradation and better performance at high temperatures. Over a 25-year installation, TopCon generates more total kWh than an equivalent PERC.
Is it compatible with all solar inverters?
Yes, it’s compatible with most inverters on the market. Contact our technical team for correct string sizing based on your inverter.
What warranty do these panels have?
Bexie modules include a product warranty and a linear performance warranty. Refer to the downloadable technical datasheet for the specific details of this model.
