The company has operated since 1995, reflecting established manufacturing experience. - **30-year power warranty guaranteeing 85.4% output** - The manufacturer guarantees a minimum of 85.4% of nominal power after 30 years of operation, a competitive result compared to standard 25-year offers in the PERC segment and comparable to premium TOPCon series from rival manufacturers. ## Cons - **12-year product warranty below market standard** - The 12-year product warranty is shorter than the 15 years now standard among many Tier-1 TOPCon module manufacturers (e.g., JinkoSolar, LONGi, Trina Solar), which may be a significant factor for projects requiring longer bankability periods. ## About this series The Premier Energies 144 HALF CUT TOPCon CELL BIFACIAL DUAL GLASS series redefines efficiency standards thanks to the combination of **TOPCon cell technology** with a bifacial module design. The use of innovative 144 Half-Cut cell architecture minimizes resistive losses, which directly translates into stable operation even in difficult lighting conditions. The key advantage is the **Bifacial Dual Glass structure**, which, through the use of glass on both sides of the panel, not only drastically increases mechanical resistance and durability for decades but, above all, allows for the generation of additional energy from radiation reflected from the ground. This solution perfectly eliminates the problem of rapid module degradation in aggressive environments, ensuring exceptional **resistance to the PID phenomenon** and micro-cracks. This series is dedicated primarily to large photovoltaic farms and advanced commercial installations, where maximizing yield per unit area is a priority. Unlike standard monofacial modules, these panels offer a significantly **lower temperature coefficient**, which means they maintain high efficiency even during hot summer days. By choosing these modules, the investor receives uncompromising durability combined with **state-of-the-art contact passivation technology**, which places this series at the forefront of the most cost-effective solutions on the Polish renewable energy market. ## Notable figures - Efficiency of 22.6% matches the \*\*TOPCon 550-600W\*\* median - At 226.5 W/m² power density, roof space requirements are typical for \*\*TOPCon 550-600W\*\* panels - At -0.30%/°C, hot weather performance is typical for \*\*TOPCon 550-600W\*\* panels - At 34.0 kg (2.8 kg above \*\*TOPCon 550-600W\*\* median of 31.2 kg), requires checking roof load capacity - In the top 26% for efficiency among all TOPCon panels ## Questions ### What warranty does the Premier Energies 144 Half Cut TOPCon Cell Bifacial Dual Glass series come with? The Premier Energies 144 Half Cut TOPCon Bifacial Dual Glass series includes a 12-year product warranty and a 30-year linear power warranty. At the end of year 30, the module is guaranteed to retain at least 85.4% of its nominal output power. This is among the most comprehensive warranty packages available, reflecting the long-term durability of the dual glass construction. ### Are the Premier Energies TOPCon Bifacial Dual Glass 590W modules suitable for large-scale solar farms? Yes, this series is specifically designed for utility-scale and large commercial PV installations. With a peak power of 590 Wp, efficiency up to 22.83%, and bifacial energy capture, these modules maximize yield per unit of land area. The frameless dual glass structure also eliminates aluminum frame corrosion in humid climates, reducing long-term balance-of-system (BoS) maintenance costs. ### What advantage does the Bifacial Dual Glass design offer over a conventional monofacial module? A bifacial module captures solar irradiance on both the front and rear surfaces, harvesting light reflected from the ground, white gravel, snow, or a light-colored roofing membrane. This translates to a 5-15% energy yield gain over a monofacial module of identical nameplate power. Additionally, replacing the rear backsheet with tempered glass significantly increases mechanical durability and extends the module's operational lifespan. ### How much does a Premier Energies 144 HC TOPCon Bifacial Dual Glass module weigh, and does it require a reinforced mounting structure? The module weighs approximately 28 kg with dimensions of 2278 × 1134 × 35 mm. The dual glass construction adds weight compared to standard monofacial modules (21-23 kg), so roof-mounted installations require a structural assessment of the rafter system and appropriately rated mounting hardware. Ground-mount and flat-roof installations are generally not affected. Consult a certified installer or structural engineer before proceeding. ### How does TOPCon cell technology affect module performance during hot summer conditions? TOPCon cells feature a temperature coefficient of Pmax of -0.30%/°C, which is better than typical PERC modules at -0.35%/°C. When a module heats up to 60°C on a sunny summer day, a TOPCon module loses less power than its PERC counterpart. Over a full year this difference meaningfully reduces LCOE, making the Premier Energies TOPCon series a cost-effective choice for high-irradiance climates. ### Is the Premier Energies 144 Half Cut TOPCon Bifacial Dual Glass series still available for purchase? Yes, this series has not been discontinued. Premier Energies continues to manufacture the 144 HC TOPCon Bifacial Dual Glass modules in the 560-590 Wp power range. Availability of specific batches in your region depends on current distributor stock levels. For large utility-scale orders, confirm allocation with an authorized importer well in advance of your project timeline. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/pe-144-hc-topcon-bifacial-dual-glass-560-590w-3ed16d3bb768.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | Cooler, lighter, +2.2 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | Cooler, lighter, +2.0 pp | | [AIKO AIKO-A635-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a635-mae72mw) | 635 W | +50 W, lighter, +2.0 pp | | [AIKO AIKO-A630-MAH72Dw](https://comparepv.com/panel/aiko-aiko-a630-mah72dw) | 630 W | +45 W, cooler, +1.8 pp | | [Longi Solar LR7-60HVHL-550M](https://comparepv.com/panel/longi-lr7-60hvhl-550m) | 550 W | Cooler, 18 kg lighter, +1.8 pp | | [Premier Energies PE 515HM](https://comparepv.com/panel/premier-energies-pe-515hm) | 515 W | -70 W, lighter, -2.7 pp | | [Premier Energies PE 520HM](https://comparepv.com/panel/premier-energies-pe-520hm) | 520 W | -65 W, lighter, -2.5 pp | | [Premier Energies PE 525HM](https://comparepv.com/panel/premier-energies-pe-525hm) | 525 W | -60 W, lighter, -2.3 pp | | [Premier Energies PE-525HB](https://comparepv.com/panel/premier-energies-pe-525hb) | 525 W | -60 W, lighter, -2.3 pp | | [Premier Energies PE 530HM](https://comparepv.com/panel/premier-energies-pe-530hm) | 530 W | -55 W, lighter, -2.1 pp | | [Premier Energies PE-530HG](https://comparepv.com/panel/premier-energies-pe-530hg) | 530 W | -55 W, hotter, -2.1 pp | | [Premier Energies PE 535HM](https://comparepv.com/panel/premier-energies-pe-535hm) | 535 W | -50 W, lighter, -1.9 pp | | [Premier Energies PE-535HG](https://comparepv.com/panel/premier-energies-pe-535hg) | 535 W | -50 W, hotter, -1.9 pp | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +65 W, lighter, +2.6 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | +60 W, lighter, +2.4 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | +55 W, lighter, +2.2 pp | --- Source: https://comparepv.com/panel/premier-energies-pei-144-585-thgb-m10 Not in this file, on the page: a thirty-year output simulator, a bifacial gain calculator and alternatives filtered by how closely they match these dimensions.
