690–730W Bifacial Solar Panel – Monocrystalline TopCon · BE690-730T9-132(HC)BF
High-power TopCon bifacial solar panel from 690 to 730W with 132 N-Type half-cut cells. Designed for utility-scale installations, offering superior efficiency, low degradation and enhanced energy yield through dual-side generation.
Overview
Bexie Energy’s BE690-730T9-132(HC)BF TopCon bifacial solar panel 700W is the highest-power module in the catalogue, designed for large-scale installations where maximising energy output per installed panel is essential. With power ratings of 690 to 730W and N-Type TopCon bifacial technology with 132 half-cut cells, it represents the most advanced option in residential and industrial photovoltaic modules.
The TopCon bifacial solar panel 700W generates energy from both sides of the module, harnessing direct radiation on the front side and light reflected from the ground on the back side, which can increase annual output by up to 25% compared with an equivalent monofacial module.

Advantages of the TopCon bifacial solar panel 700W over conventional modules
The TopCon bifacial solar panel 700W outperforms conventional PERC modules in all key parameters:
- Higher power per panel — fewer units needed for the same kWp
- Bifacial generation — up to 25% more annual output
- Lower annual degradation thanks to N-Type technology (reduced LID/LeTID)
- Better performance under high temperatures and low irradiance
- Higher efficiency per m² — less surface area required
- Lower installation cost per kWp by needing fewer panels and mounting structure
Applications of the TopCon bifacial solar panel 700W
The TopCon bifacial solar panel 700W is particularly suited for:
- Utility-scale ground-mount solar plants
- Large industrial and logistics roofs
- Projects looking to minimise the number of installed panels
- Installations with elevated structures that take advantage of bifaciality
- Energy communities and shared self-consumption projects
- Large-scale agricultural installations (agrivoltaics)
Advantages of the 132 half-cut cell format in high-power modules
The 132 half-cut cells of the TopCon bifacial solar panel 700W deliver decisive advantages in large-scale installations:
- Higher power per panel — fewer units, less mounting structure, less labour
- Reduced internal resistance thanks to the half-cut design
- Greater tolerance to partial shading
- Fewer connections in the string — lower risk of faults
- Lower BOS (balance of system) cost per installed kWp

Performance of the TopCon bifacial solar panel 700W under real-world conditions
On south-facing ground-mount installations with a 30-35° tilt in southern Europe, the TopCon bifacial solar panel 700W can generate between 700 and 800 kWh per year per installed panel on its front side. The bifacial contribution can add between 40 and 200 kWh extra depending on the ground albedo and the height of the structure.
This translates into average savings of between 100 and 150 euros per year per panel at current energy prices, with a typical payback period of 5 to 7 years on industrial installations. More information on photovoltaic module performance is available at the European Commission’s PVGIS portal.

The TopCon bifacial solar panel 700W can be combined with our high-power hybrid inverters, BESS storage systems and solar mounting structures for a complete and optimised industrial PV installation. Take a look as well at the rest of the Bexie solar panel catalogue.
Frequently asked questions about the TopCon bifacial solar panel 700W
Which inverter do I need for this TopCon bifacial solar panel 700W?
As a high-power, high-current panel, it requires an inverter compatible with high-current modules. Contact our technical team for accurate string sizing and the selection of the most suitable inverter for your installation.
How many panels do I need for a 100 kWp plant?
With this 730W module, you would need approximately 137 panels to reach 100 kWp. This represents significant savings on mounting structure, wiring and labour compared with lower-power modules.
How much more does it produce by being bifacial?
The bifacial gain of the TopCon bifacial solar panel 700W depends on the ground albedo and the height of the structure. On ground-mount installations with white gravel and elevated structures, the gain can be up to 20-25% over the front-side output.
Is it compatible with standard mounting structures?
Yes, although due to its size (2384x1303mm) it requires specific structures for large-format modules. Take a look at our range of mounting structures or contact our team for the design of the installation.
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.
