This solution is crucial for residential installations, where chimneys or neighboring buildings often cast shade on roof surfaces. Thanks to **increased mechanical strength**, the design of the panels handles extreme snow loads and strong winds perfectly, ensuring safety and stable electricity production for decades. These modules stand out from the competition due to rigorous quality testing that goes far beyond standard industry norms, making them an ideal choice for investors seeking American reliability and precision. The **optimized 108-cell configuration** allows for easier installation and better compatibility with modern inverters, which effectively lowers the costs of the entire system. By choosing this series, the user receives **maximum efficiency in low-light conditions**, which is a significant advantage in the Polish climate, characterized by many cloudy days. It is a solution dedicated to both prosumers and commercial projects that value uncompromising durability and efficiency from every square meter of the roof. ## Notable figures - At 20.5% efficiency, this panel is on par with typical \*\*PERC 400-450W\*\* modules - Power density of 204.5 W/m² matches the \*\*PERC 400-450W\*\* median - At -0.34%/°C, hot weather performance is typical for \*\*PERC 400-450W\*\* panels - Weight of 19.0 kg (3.0 kg below \*\*PERC 400-450W\*\* median of 22.0 kg) allows easier transport and roof mounting - Ranked #11308 out of 14005 panels for efficiency in the database ## Questions ### Is the Mission Solar MSE PERC 108HC series still available for purchase? The Mission Solar MSE PERC 108HC series has been discontinued by the manufacturer. New modules are only available from existing distributor stock, so supply is limited. Verify current availability with your supplier before placing an order. For new installations, consider newer models from Mission Solar's active lineup or an alternative manufacturer that can provide ongoing product and warranty support. ### What warranty does Mission Solar offer on the MSE PERC 108HC panels? Mission Solar provides a 25-year product warranty covering defects in materials and workmanship, along with a 25-year power output warranty. This dual 25-year coverage is among the stronger guarantees in the residential segment. Because the series is discontinued, buyers should confirm directly with their distributor how warranty claims will be processed to avoid uncertainty if a module issue arises years down the line. ### How do PERC technology and half-cut cells affect MSE PERC 108HC performance on overcast days? PERC (Passivated Emitter Rear Contact) technology adds a reflective rear passivation layer to each cell, boosting energy harvest under diffuse and low-irradiance conditions. The 108 half-cut cell layout reduces resistive losses and limits the impact of partial shading from chimneys or neighboring structures. For climates with frequent cloud cover, both features translate into measurably higher annual energy yield compared to standard full-cell monocrystalline modules. ### What are the weight and mechanical load ratings of the MSE PERC 108HC panel? The module weighs approximately 19 kg and measures 1723 × 1135 × 35 mm — standard dimensions for a 410 W class panel. It is engineered to withstand snow and wind loads up to 5,400 Pa, meeting European structural standards, and has passed third-party hail impact tests with hailstones exceeding 55 mm diameter at 33.9 m/s. These ratings make it well suited for demanding Central European weather conditions including heavy snowfall and hailstorms. ### What is the rated power of the MSE PERC 108HC and which inverters is it compatible with? The module delivers a peak output of 410 W at STC, with a maximum power point voltage (Vmpp) of 31.45 V, MPPT current (Impp) of 13.04 A, and open-circuit voltage (Voc) of 37.32 V. The 108 half-cut cell configuration is compatible with most modern string inverters featuring MPPT inputs — including single-phase and three-phase models from Fronius, SMA, SolarEdge, and Huawei — with no additional optimizers or adapters required for standard string designs. ### How does the Mission Solar MSE PERC 108HC differ from standard monocrystalline panels? Compared to conventional monocrystalline modules, the MSE PERC 108HC achieves approximately 21% module efficiency through PERC cell technology combined with 10-busbar metallization per cell. The half-cut cell design reduces resistive heating and improves partial-shading tolerance relative to full-cell modules. In practice, this means higher energy output per square meter of roof area, especially on rooftops where a chimney, dormer, or adjacent structure periodically shades part of the array. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/MSI-PERC-108HC-aae07e1b1ed1.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Luxor Solar LX-440M/182-108+GG](https://comparepv.com/panel/luxor-solar-lx-440m-182-108-gg) | 440 W | Cooler, +2.6 pp, +5 yr warranty | | [Just Solar JST-EDMH-(445-465)W-TD (450W class)](https://comparepv.com/panel/just-solar-jst-edmh-445-465-w-td-450w-class) | 450 W | +50 W, +2.6 pp, +5 yr warranty | | [Q-SUN Solar QNN182-HG450-54](https://comparepv.com/panel/qn-solar-pv-limited-qnn182-hg450-54) | 450 W | +50 W, cooler, +2.5 pp | | [Huayao HY440-N108BDD](https://comparepv.com/panel/huayao-hy440-n108bdd) | 450 W | +50 W, +2.5 pp, +5 yr warranty | | [BYD NLBK-27-450](https://comparepv.com/panel/byd-nlbk-27-450) | 450 W | +50 W, +2.5 pp, +5 yr warranty | | [Renesola RS41-450NBG-E3](https://comparepv.com/panel/renesola-rs41-450nbg-e3) | 450 W | Cooler, heavier, +2.5 pp | | [Mission Solar MSE405HT0B](https://comparepv.com/panel/mission-solar-mse405ht0b) | 405 W | Very close match | | [Mission Solar MSE410HT0B](https://comparepv.com/panel/mission-solar-mse410ht0b) | 410 W | +10 W, +0.5 pp | | [Mission Solar MSX10-435HN0B](https://comparepv.com/panel/mission-solar-msx10-435hn0b) | 435 W | Cooler, +1.8 pp, +5 yr warranty | | [Mission Solar MSX10-440HN0B](https://comparepv.com/panel/mission-solar-msx10-440hn0b) | 440 W | Cooler, +2.0 pp, +5 yr warranty | | [Mission Solar MSX10-445HN0B](https://comparepv.com/panel/mission-solar-msx10-445hn0b) | 445 W | Cooler, +2.3 pp, +5 yr warranty | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +110 W, cooler, +4.5 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +95 W, cooler, +4.3 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +105 W, cooler, +4.2 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +90 W, cooler, +4.0 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +100 W, cooler, +4.0 pp | --- Source: https://comparepv.com/panel/mission-solar-mse400ht0b Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
