510–545W Solar Panel – Monocrystalline TopCon · BE510-545T8-132(HC)
TopCon monocrystalline photovoltaic module from 510 to 545W with 132 half-cut cells. Next-generation technology that outperforms PERC in efficiency and durability, with a low annual degradation rate and exceptional performance under low-irradiance and high-temperature conditions.
Overview
Bexie Energy’s BE510-545T8-132(HC) TopCon monocrystalline solar panel represents the natural evolution of photovoltaic technology. With power ratings of 510 to 545W and next-generation half-cut cells, it delivers superior efficiency and minimal degradation throughout its lifespan.
TopCon monocrystalline solar panel (Tunnel Oxide Passivated Contact) reduces recombination losses in the solar cell, achieving higher performance than conventional PERC modules, particularly under high-temperature and low-irradiance conditions.
Technical specifications of the TopCon solar panel

Advantages of half-cut cells (132 cells)
Half-cut cells split each solar cell in two, reducing internal resistance and improving performance under partial shading.
- Lower losses from internal resistance
- Greater tolerance to partial shading
- Lower module heating
- Higher annual energy output
- Greater long-term reliability
Applications of the TopCon photovoltaic module
- Residential self-consumption installations
- Industrial and commercial PV installations
- Utility-scale ground-mount solar plants
- Installations on flat or pitched roofs
- Shared self-consumption projects and energy communities
- Integration with storage systems and batteries
Performance under real-world conditions
N-type TopCon technology stands out particularly in installations where conditions aren’t always ideal. Its low negative temperature coefficient guarantees that summer output losses are minimal, while its high sensitivity to diffuse light maximises generation on cloudy days or in winter.
This translates into higher real annual output compared with equivalent PERC modules, improving the return on investment and reducing the payback period of the installation.
In south-facing installations with a 30-35° tilt in southern Europe, this module can generate between 500 and 550 kWh per year per installed panel, depending on the geographical area and local conditions. This represents average savings of between 75 and 90 euros per year per panel at current energy prices, with a typical payback period of 6 to 8 years for a complete residential installation.
Integration with the complete PV system
This solar panel can be combined with our hybrid inverters, storage batteries and mounting structures for a complete and optimised self-consumption installation.
Frequently asked questions about TopCon solar panels
What’s the difference between a TopCon panel and a PERC panel?
TopCon technology adds a tunnel oxide layer on the back of the cell that reduces losses from electron recombination. The result is higher efficiency, lower annual degradation and better performance at high temperatures compared with conventional PERC modules.
Are they compatible with any solar inverter?
Yes, the BE510-535T8-132(HC) modules are compatible with most inverters on the market. Contact our technical team to correctly size the string and the inverter for your installation.
How many panels do I need for my installation?
It depends on your electricity consumption, available surface area and roof orientation. With this 535W module, a typical 5 kWp domestic installation would require approximately 10 panels. Request a free assessment for your specific case.
What warranty do these solar 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.
Do they perform well in areas with many cloudy days?
Yes, N-type TopCon technology has high sensitivity to diffuse light, which improves output on cloudy days or under low irradiance compared with conventional PERC modules.
