The use of **half-cut cells** reduces resistive losses and improves module behavior under partial shading, which translates into meaningfully higher energy yield in demanding site conditions. The defining feature of this series, however, is its **bifacial double-glass** construction - glass instead of a rear backsheet allows the module to capture light reflected off the ground, boosting total energy output without increasing the installation footprint. The panels also stand out for their **high environmental resistance**, including resistance to salt mist corrosion, ammonia, sand and dust, and potential induced degradation (PID), making them a strong fit for industrial, agricultural, and coastal installations. The glass-glass structure additionally gives the modules greater mechanical rigidity and better resistance to physical damage compared to conventional backsheet panels. The manufacturer backs the series with a **long-term warranty extending up to 30 years**, supporting a lower LCOE over the system's full lifecycle. This makes the series a strong fit primarily for commercial and industrial investors who prioritize yield stability and low failure rates over the lowest upfront price. ## Notable figures - Efficiency of 21.3% matches the \*\*PERC 650-700W\*\* median - Power density of 212.7 W/m² matches the \*\*PERC 650-700W\*\* median - At -0.34%/°C, hot weather performance is typical for \*\*PERC 650-700W\*\* panels - At 37.0 kg, this panel is 2.5 kg heavier than the \*\*PERC 650-700W\*\* median (34.5 kg) - more demanding for installation crews - 70% bifaciality enables rear-side power generation, boosting yield by 4-10% on reflective surfaces ## Questions ### What is the maximum power output of the AURORA ME-132BD panels and what makes it so high? The AURORA ME-132BD series reaches a maximum power output of up to 660 Wp. This high output comes from the 132 half-cut PERC cell design, which reduces resistive losses and improves performance under partial shading, combined with the bifacial construction that captures additional energy from the rear side of the module. ### How does a bifacial double-glass module differ from a standard backsheet panel? A classic panel uses a backsheet on the rear side, which blocks light entirely. The AURORA ME-132BD uses two glass layers instead, allowing the module to also capture light reflected from the ground, increasing total energy yield without expanding the installation footprint. The glass-glass build is also stiffer and more resistant to mechanical damage than a standard backsheet design. ### What warranty comes with the AURORA ME-132BD panels? AE Solar provides a 15-year product warranty and a 30-year power performance warranty for the AURORA ME-132BD series. This extended coverage lowers the LCOE over the system's full lifecycle, which is especially valuable for commercial and industrial investors planning long-term operation. ### Are the AURORA ME-132BD panels suitable for coastal or agricultural installations? Yes, the series offers high resistance to salt mist corrosion, ammonia, sand, and potential induced degradation (PID). This makes it well suited for demanding environments typical of coastal, agricultural, and industrial installations, where standard panels might degrade faster. ### What type of investor is the AURORA ME-132BD series designed for? The AURORA ME-132BD series targets commercial and industrial investors who prioritize stable energy yield and low failure rates over the lowest purchase price. The high power output of up to 660 Wp combined with a long-term warranty makes it cost-effective for large rooftop and ground-mounted installations. ### Is AE Solar a Tier 1 manufacturer and where is the company based? AE Solar is classified as a Tier 1 manufacturer and is headquartered in Germany. Tier 1 status reflects financial stability and a proven production track record, offering investors added assurance when relying on long-term warranty commitments for panels like the AURORA ME-132BD. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/AE_ME_132_BD_640_W_660_W_SC_11_5_Ver26_8_1_1c5850e2b1-4689a541bcb7.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | Cooler, lighter, +3.9 pp | | [AIKO AIKO-A680-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a680-mde72mw) | 680 W | Cooler, lighter, +3.9 pp | | [AIKO AIKO-A675-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a675-mde72mw) | 675 W | Cooler, lighter, +3.7 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | Cooler, lighter, +3.7 pp | | [AIKO AIKO-A700-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a700-mae78dw) | 700 W | +40 W, cooler, +3.7 pp | | [AIKO AIKO-A695-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a695-mae78dw) | 695 W | +35 W, cooler, +3.6 pp | | [AIKO AIKO-G670-MCH72Mw](https://comparepv.com/panel/aiko-aiko-g670-mch72mw) | 670 W | Cooler, lighter, +3.5 pp | | [AE Solar AE ME-132 640W](https://comparepv.com/panel/ae-solar-ae-me-132-640w) | 640 W | -20 W, lighter, -0.6 pp | | [AE Solar AE ME-132 645W](https://comparepv.com/panel/ae-solar-ae-me-132-645w) | 645 W | -15 W, lighter, -0.5 pp | | [AIKO AIKO-A805-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a805-grh78dw) | 805 W | +145 W, cooler, +3.8 pp | | [AIKO AIKO-A800-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a800-grh78dw) | 800 W | +140 W, cooler, +3.6 pp | | [AIKO AIKO-A795-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a795-grh78dw) | 795 W | +135 W, cooler, +3.5 pp | | [AIKO AIKO-A790-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a790-grh78dw) | 790 W | +130 W, cooler, +3.3 pp | | [Trina Solar TSM-NEG21C.20Q-760](https://comparepv.com/panel/trina-solar-tsm-neg21c-20q-760) | 760 W | +100 W, cooler, +3.2 pp | | [AIKO AIKO-A785-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a785-grh78dw) | 785 W | +125 W, cooler, +3.1 pp | | [Gokin GK-4-78HGBD-780M](https://comparepv.com/panel/gokin-gk-4-78hgbd-780m) | 780 W | +120 W, cooler, +3.0 pp | --- Source: https://comparepv.com/panel/ae-solar-me-132bd-660 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.
