In practice, this translates to a meaningfully smaller roof area required for the same energy yield. - **Domestic Manufacturing, Local After-Sales Support** - Bruk-Bet has been manufacturing modules in Poland since 1984 at its facility in Niechobrz, Subcarpathia. The shortened supply chain eliminates foreign-exchange risk on warranty claims, accelerates access to technical support, and removes dependence on sourcing replacement parts from Asia — a significant advantage over a 25-year operating horizon. - **8,000 Pa Snow Load / 5,400 Pa Wind Uplift Rating** - The module withstands a static snow load of 8,000 Pa and a wind uplift of 5,400 Pa, well in excess of Polish climatic standard requirements for the vast majority of installation sites. This is particularly important for agricultural and industrial rooftop installations exposed to heavy hail and high wind loads. - **83% Power Output Guarantee After 25 Years** - Bruk-Bet warrants at least 83% of nominal power output after 25 years, exceeding the IEC minimum threshold of 80%. The module is certified to IEC 61215:2016 and IEC 61730:2017, confirming compliance with current performance and safety standards. ## Cons - **PERC — A Technology Losing Market Share** - In 2024, PERC's share of global module shipments fell from approximately 63% (2023) to ~40%, with TOPCon emerging as the dominant technology. A direct competitor in the same power class — the Just Solar IBC Mono Module 360 Wp — achieves an efficiency of 21.3%, or 1.67 percentage points higher than the Extreme Plus. By selecting a PERC module in 2025/2026, investors forgo the lower LID degradation and superior high-temperature energy yield that are characteristic of N-type cell technologies. - **Low Nominal Power of 360 Wp** - The current mainstream for mono PERC modules is 400–550 Wp. At 360 Wp, achieving a given system capacity requires a greater number of modules and connectors, increasing both installation costs and the number of potential failure points — an effect that becomes especially pronounced in systems above 10 kWp. - **15-Year Product Warranty — Conditional** - The standard product warranty is 12 years; the 15-year term applies only when the system is installed by a Bruk-Bet Authorized Partner or upon purchase of a paid warranty extension. For installations carried out by contractors outside the authorized partner network, the effective product warranty reverts to 12 years — below the 15-year figure cited in promotional materials. ## About this series The Bruk-Bet Extreme Plus series was designed as a practical compromise between traditional 60- and 72-cell modules - thanks to its unconventional cell configuration, it is easier to achieve high output from a limited roof area without "over-sizing" the panel itself. This solution will be appreciated by investors when every square meter and the aesthetic appearance of the roof are important. A key feature of the series is the **optimized power-to-size ratio**, as well as the emphasis on **increased mechanical strength**, which is essential in Polish conditions - with strong winds and heavy snowfall. Extreme Plus aims for stable operation in challenging environments, making it suitable not only for residential and commercial roofs, but also for agricultural installations and ground-mounted systems. For the contractor, this also means easier installation - the series simplifies string design and matching to the inverter, while the user gains **more reliable energy production** in hot weather thanks to its **favorable temperature characteristics**. Extreme Plus is chosen by those who want equipment that will last for years, rather than just the cheapest option. ## Notable figures - Efficiency of 19.6% matches the \*\*PERC 0-400W\*\* median - At 196.3 W/m² power density, roof space requirements are typical for \*\*PERC 0-400W\*\* panels - At -0.36%/°C, hot weather performance is typical for \*\*PERC 0-400W\*\* panels - In the top 90% for efficiency among all PERC panels ## Questions ### Why do Bruk-Bet Extreme Plus panels feature 66 cells rather than the standard 60 or 72? The Extreme Plus series uses a 66-cell PERC layout as a deliberate compromise between the two classic formats. Its smaller footprint (1825 × 1005 mm) compared to a 72-cell module allows more panels to be fitted on roof surfaces with limited area, while the higher power output relative to a 60-cell module translates into better energy yield per square meter of rooftop. This is especially advantageous on the irregular roof geometries typical of single-family residential buildings. ### What warranty is offered on the Bruk-Bet Extreme Plus 360W panels? The manufacturer provides a 15-year product warranty and a 25-year linear power output warranty. This means that over a quarter of a century the panel is guaranteed to retain the minimum efficiency specified in the product datasheet. This is one of the longer power warranties available in this price class and is a significant factor when evaluating the return on investment. ### Can Bruk-Bet Extreme Plus panels withstand strong winds and hail under Polish climate conditions? Yes, the Extreme Plus series has passed certification tests confirming resistance to wind loads of up to 5,400 Pa and snow loads of up to 8,100 Pa, as well as hail impact at a velocity of 122 km/h. These ratings exceed the requirements for the vast majority of locations in Poland, making the modules a reliable choice for residential rooftops as well as agricultural and industrial installations exposed to harsh weather. ### Does the PERC technology in the Extreme Plus series matter for performance during summer heat? Yes, monocrystalline PERC cells exhibit a more favorable temperature coefficient than older standard cells, meaning they suffer a smaller power loss at elevated temperatures. In practical terms, this translates into higher energy production on hot, sunny days when modules on a roof surface can heat up to 60–70 °C. ### Are Bruk-Bet Extreme Plus 360W panels manufactured in Poland? Yes, Bruk-Bet Solar is headquartered and manufactures its products in Poland. This is relevant information for investors who prioritize a domestic supply chain, shorter lead times, and direct contact with the manufacturer in the event of a warranty claim, eliminating the need to correspond with distant overseas factories. ### Are Bruk-Bet Extreme Plus 360W panels compatible with popular inverters, and how should a string be designed? The module's open-circuit voltage of 44.70 V and rated power of 360 W are compatible with the vast majority of inverters available on the market, including SMA, Fronius, Huawei, Sofar, and others. Thanks to the intermediate 66-cell format, it is easier to match the number of panels in a string to the MPPT window of the inverter, avoiding both undersizing and exceeding the inverter's maximum input voltage. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/bem-360-w-extreme-plus-ws-09-06-22-1-b57e24d9fa97.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [JA Solar NS-330MH-80](https://comparepv.com/panel/ja-solar-ns-330mh-80) | 330 W | Cooler, lighter, +3.5 pp | | [PolyCrown Solar Tech NS-330MH-80](https://comparepv.com/panel/polycrown-solar-tech-ns-330mh-80) | 330 W | Cooler, lighter, +3.5 pp | | [Gamko New Energy GKA210M320W](https://comparepv.com/panel/gamko-new-energy-gka210m320w) | 320 W | Lighter, +3.4 pp, +5 yr warranty | | [Gamko New Energy GKA210M340W](https://comparepv.com/panel/gamko-new-energy-gka210m340w) | 340 W | Lighter, +3.4 pp, +5 yr warranty | | [Gamko New Energy GKA210M360W](https://comparepv.com/panel/gamko-new-energy-gka210m360w) | 360 W | Lighter, +3.4 pp, +5 yr warranty | | [Gamko New Energy GKA210M380W (1/4\*4\*38)](https://comparepv.com/panel/gamko-new-energy-gka210m380w-1-4-4-38) | 380 W | Lighter, +3.4 pp, +5 yr warranty | | [Gamko New Energy GKA210M400W (1/2\*4\*20)](https://comparepv.com/panel/gamko-new-energy-gka210m400w-1-2-4-20) | 400 W | +40 W, +3.4 pp, +5 yr warranty | | [Gamko New Energy GKA210M400W (1/4\*4\*40)](https://comparepv.com/panel/gamko-new-energy-gka210m400w-1-4-4-40) | 400 W | +40 W, +3.4 pp, +5 yr warranty | | [Gamko New Energy GKA210M380W (1/2\*4\*19)](https://comparepv.com/panel/gamko-new-energy-gka210m380w-1-2-4-19) | 380 W | Lighter, +3.4 pp, +5 yr warranty | | [Maxeon SPR-MAX3-400-COM](https://comparepv.com/panel/maxeon-spr-max3-400-com) | 400 W | Cooler, +3.0 pp, +15 yr warranty | | [Maxeon SPR-MAX7-475](https://comparepv.com/panel/maxeon-spr-max7-475) | 475 W | +115 W, +4.4 pp, +15 yr warranty | | [Maxeon SPR-MAX7-470](https://comparepv.com/panel/maxeon-spr-max7-470) | 470 W | +110 W, +4.1 pp, +15 yr warranty | | [Maxeon SPR-MAX7-465](https://comparepv.com/panel/maxeon-spr-max7-465) | 465 W | +105 W, +3.9 pp, +15 yr warranty | | [Jetion JT440SYK(B)](https://comparepv.com/panel/jetion-jt440syk-b) | 440 W | +80 W, cooler, +3.3 pp | | [Maxeon SPR-MAX6-440](https://comparepv.com/panel/maxeon-spr-max6-440) | 440 W | +80 W, +3.2 pp, +15 yr warranty | | [Jetion JT435SYk(B)](https://comparepv.com/panel/jetion-jt435syk-b) | 435 W | +75 W, cooler, +3.1 pp | --- Source: https://comparepv.com/panel/bruk-bet-bem-360 Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
