TOPCon Bifacial 585W (TE-585-N144M10)
Categories: TOPCON BIFICIAL SOLAR PANEL
The Triex TOPCon 585W is an N-Type mono-bifacial solar panel built for high-performance residential and commercial solar installations in Pakistan. Using Tunnel Oxide Passivated Contact technology, TOPCon cells achieve higher conversion efficiency and lower degradation rates than conventional PERC panels, delivering more energy from the same rooftop area over a longer period.
At 22.65% module efficiency, the TE-585-N144M10 extracts more power per square meter than most standard panels available in the Pakistani market. For homeowners with limited rooftop space, this means fewer panels are needed to achieve the same system capacity, reducing mounting costs and structural load on the roof.
The bifacial design captures sunlight from both the front and rear surfaces of the panel. On a standard white or reflective rooftop surface common in Pakistan, the rear gain adds up to 15% additional power generation without any additional panels. This means a 585W rated panel can deliver up to 678.5W under ideal bifacial conditions, effectively increasing the energy yield of the entire array at no additional hardware cost.
HOT 2.0 technology reduces Light Induced Degradation and Light and Elevated Temperature Induced Degradation, which are the primary causes of early power loss in solar panels. Standard PERC panels can lose 1 to 3% of their rated power in the first year from LID alone. HOT 2.0 minimizes this loss, keeping the panel closer to its rated output from day one throughout its service life.
The IP68 rated junction box protects the panel’s electrical connections from complete water immersion, making it well suited for Karachi’s monsoon season and the rooftop water pooling common in flat-roof Pakistani homes. The anodized aluminium alloy frame and heat-strengthened back glass provide structural integrity against the 2400Pa wind load and 5400Pa snow load certifications, covering Pakistan’s range of weather conditions from coastal Karachi to northern areas.
TUV Rheinland, CEC, CE, ISO, and multiple additional certifications confirm that the panel meets international quality and safety standards, an important consideration for NEPRA net metering applications where certified equipment is required.

Who Should Buy This
The TE-585-N144M10 585W TOPCon panel is the right choice for Pakistani homeowners and businesses who want maximum energy generation from their available rooftop space. It is ideal for homes with limited roof area where standard 400W to 500W panels would require more panels to reach the target system capacity, and for buyers who want lower long-term degradation and higher reliability over a 25 to 30 year panel lifespan.
It is particularly well suited for K-Electric net metering applications in Karachi and NEPRA net metering installations across Pakistan where certified high-efficiency panels deliver better return on investment through higher energy yields.
