The use of a **bifacial design with a transparent backsheet** allows for the effective utilization of light reflected from the surface beneath the module, which translates directly into higher annual energy generation without the need for expanding the installation. The **PERC cell technology** combined with the **half-cut architecture** also enhances module performance under partial shading and reduces losses due to mismatch. Furthermore, the **multi-busbar connection system** ensures stable operation over a long period, increasing reliability in demanding conditions. This solution is ideal for commercial investors, PV farms, and projects where high energy production, operational reliability, and cost-effectiveness throughout the entire lifespan of the installation are priorities. ## Notable figures - Module efficiency of 20.3% is 0.6pp below average for \*\*PERC 500-550W\*\* panels (median: 20.9%) - Power density of 203.2 W/m² is 5.8 W/m² below \*\*PERC 500-550W\*\* median (209.0 W/m²) - needs more roof space - At -0.35%/°C, hot weather performance is typical for \*\*PERC 500-550W\*\* panels - Ranked #11739 out of 14005 panels for efficiency in the database ## Questions ### What additional energy yield can I expect from the bifacial transparent backsheet design of the Premier Energies 144 Half Cut PERC series? The transparent backsheet allows reflected light from the ground surface to be absorbed by the rear side of the module. With high-albedo surfaces such as white concrete, light-colored membranes, or sand, rear-side gain typically ranges from 5–15% relative to front-side rated power. The effect is most pronounced on ground-mounted systems and flat rooftops with light-colored coatings, and significantly lower on steep dark-tiled roofs. ### What warranty is included with the Premier Energies 144 Half Cut PERC Cell Bifacial Transparent Backsheet series? Premier Energies provides a 12-year product warranty covering material and workmanship defects, complemented by a 30-year linear power output warranty guaranteeing that the modules maintain specified performance levels over three decades of operation. The 30-year power warranty places this series among the better-covered options available in the standard PERC segment. ### Are Premier Energies 144 HC PERC Bifacial modules suitable for a utility-scale PV farm with a light gravel substrate? Yes, this is one of the most favorable use cases for this series. Light gravel has a high albedo coefficient, which directly increases rear-side generation on a bifacial module. With a peak power of 555 Wp combined with elevated rear-side gain, the series is particularly attractive for commercial and utility-scale ground-mounted projects, especially when single-axis trackers are used to further optimize annual yield. ### How does the half-cut cell architecture and multi busbar design affect module performance under partial shading? The half-cut design splits each cell into two, so shading one section of a row reduces only half of its power output instead of the full cell's contribution. Multi busbar technology shortens current paths, reduces resistive losses, and lowers thermomechanical stress on cell interconnects. The combined result is a smaller production drop when part of the array is shaded by chimneys, dormers, or adjacent module rows. ### Where is Premier Energies headquartered, and are Indian-manufactured solar panels reliable? Premier Energies is headquartered in India and is one of the country's leading PV module manufacturers. Their modules are certified to IEC 61215, IEC 61730, and IEC 62804 (PID resistance), and hold CE approval along with ratings for salt mist (IEC 61701) and ammonia resistance (IEC 62716). Active exports to European markets confirm that the product line meets stringent international quality standards. ### What is the module efficiency of the Premier Energies 144 Half Cut PERC Bifacial series, and how does it compare to budget alternatives? Modules in this series achieve efficiency between 20.3–21.29%, with cell efficiency reaching up to 22.9%. That figure is competitive with top-tier PERC offerings. The combination of PERC cell technology, half-cut architecture, and bifacial transparent backsheet allows more energy to be harvested from the same roof or ground footprint compared to conventional monofacial modules with lower per-unit wattage. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/pe-144-hc-perc-bifacial-transparent-525-555w-8a1171133bb7.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | Cooler, lighter, +4.7 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | Cooler, lighter, +4.5 pp | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | +35 W, cooler, +4.5 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | Cooler, lighter, +4.4 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | +30 W, cooler, +4.3 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | Cooler, lighter, +4.2 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | Cooler, lighter, +4.2 pp | | [Premier Energies PE 515HM](https://comparepv.com/panel/premier-energies-pe-515hm) | 515 W | -10 W, -0.4 pp, -5 yr warranty | | [Premier Energies PE 520HM](https://comparepv.com/panel/premier-energies-pe-520hm) | 520 W | Heavier, -5 yr warranty | | [Premier Energies PE 525HM](https://comparepv.com/panel/premier-energies-pe-525hm) | 525 W | Heavier, -5 yr warranty | | [Premier Energies PE 530HM](https://comparepv.com/panel/premier-energies-pe-530hm) | 530 W | Heavier, -5 yr warranty | | [Premier Energies PE-530HG](https://comparepv.com/panel/premier-energies-pe-530hg) | 530 W | Heavier | | [Premier Energies PE 535HM](https://comparepv.com/panel/premier-energies-pe-535hm) | 535 W | +10 W, +0.4 pp, -5 yr warranty | | [Premier Energies PE-535HG](https://comparepv.com/panel/premier-energies-pe-535hg) | 535 W | +10 W, heavier, +0.4 pp | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +125 W, cooler, +4.9 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | +120 W, cooler, +4.7 pp | --- Source: https://comparepv.com/panel/premier-energies-pe-525hb Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
