The panel uses **n-type monocrystalline TOPCon half-cut cells**, translating into higher conversion efficiency and lower power losses under partial shading. The **dual glass** construction combined with **bifacial** technology captures light reflected off the surrounding surface, generating extra energy from the rear side of the panel without expanding the installation footprint. This makes it especially valuable for projects with light-colored ground cover, flat commercial roofs, and utility-scale solar farms, where every additional watt counts. The robust **glass-glass build** offers better resistance to moisture ingress, microcracks, and long-term degradation, effectively extending system lifespan and lowering the levelized cost of energy (LCOE). A low power temperature coefficient keeps the module performing well even on hot days, while the **low LID/LeTID degradation** characteristic of TOPCon technology increases confidence in long-term yield projections. It's a strong choice for installers and investors seeking the balance of high power output, durability, and predictable return on investment. ## Notable figures - Efficiency of 21.9% is 0.5pp below the \*\*TOPCon 550-600W\*\* median (22.4%) - 219.0 W/m² power density is 5.4 W/m² below \*\*TOPCon 550-600W\*\* median (224.4 W/m²) - requires larger installation area - Temperature coefficient of -0.29%/°C matches the \*\*TOPCon 550-600W\*\* median - Bifaciality factor of 80% can add 4-12% extra yield with reflective mounting surface - Ranked #6783 out of 14005 panels for efficiency in the database ## Questions ### How much power does the DESERV Extreme 144X M10R TOPCon panel generate thanks to bifacial technology? The panel delivers up to 610 Wp of nominal power from the front side, and thanks to its dual-glass, bifacial design it also generates additional energy from the rear side using light reflected off the surrounding surface. With a bright ground surface or roof, energy yield can increase by up to several percent compared to a classic monofacial panel of the same power. ### How does the TOPCon cell differ from classic PERC cells in this RenewSys series? The n-type TOPCon cells used in DESERV Extreme offer higher conversion efficiency and lower power losses than older p-type PERC cells. TOPCon technology also features significantly lower LID and LeTID degradation, resulting in more stable energy production throughout the system's lifetime, especially noticeable after several years of operation. ### What warranty comes with the DESERV Extreme 144X M10R panels and what does it cover? RenewSys provides a 12-year product warranty covering material and manufacturing defects, plus a 30-year linear power warranty guaranteeing a minimum output level over time. This is a standard offering typical of tier 1 manufacturers, giving investors confidence in the long-term profitability of their PV investment. ### Is the dual-glass construction of this panel more durable than a standard glass-backsheet design? Yes, the glass-glass construction offers better sealing and resistance to moisture, microcracks, and material degradation compared to panels with a rear polymer backsheet. This makes the module more resilient to harsh weather conditions, extends its lifespan, and lowers annual degradation, which reduces LCOE over the full lifetime of the installation. ### Where does the bifacial DESERV Extreme panel perform best - on a roof or in a solar farm? The panel achieves its full potential in ground-mounted solar farms and on flat roofs with a bright surface, such as white gravel or a reflective roofing membrane, since these surfaces reflect more light onto the rear side of the module. On sloped roofs with dark coverings, the bifacial gain will be less pronounced, though the module still delivers high efficiency thanks to TOPCon technology. ### Is RenewSys a tier 1 manufacturer and where are its panels made? Yes, RenewSys holds tier 1 manufacturer status, reflecting financial stability and a proven track record in large-scale PV projects. The company is headquartered in India and is one of the leading Asian PV module manufacturers, supplying components to both the domestic Indian market and export markets, including Europe. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/37b508_0d89b3eb3ba447d6b3de4bd0507c098f-981988bb057b.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | Cooler, lighter, +2.9 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | Cooler, lighter, +2.7 pp | | [Longi Solar LR7-60HVHL-550M](https://comparepv.com/panel/longi-lr7-60hvhl-550m) | 550 W | Cooler, 15 kg lighter, +2.5 pp | | [JA Solar JAT60S40-540/LR](https://comparepv.com/panel/ja-solar-jat60s40-540-lr) | 540 W | Cooler, lighter, +2.5 pp | | [Gokin GK-5-60HG-540M](https://comparepv.com/panel/gokin-gk-5-60hg-540m) | 540 W | Cooler, lighter, +2.5 pp | | [Jinko Solar JKM545-54QL6-DV-F1-EU](https://comparepv.com/panel/jinko-solar-jkm545-54ql6-dv-f1-eu) | 545 W | Cooler, lighter, +2.4 pp | | [Longi Solar LR7-60HVH-545M](https://comparepv.com/panel/longi-lr7-60hvh-545m) | 545 W | Cooler, lighter, +2.3 pp | | [Renewsys DESERV Extreme 144X-570](https://comparepv.com/panel/renewsys-deserv-extreme-144x-570) | 570 W | Very close match | | [Renewsys DESERV Extreme 144X-575](https://comparepv.com/panel/renewsys-deserv-extreme-144x-575) | 575 W | +10 W, +0.4 pp | | [Renewsys DESERV Extreme 144X-580](https://comparepv.com/panel/renewsys-deserv-extreme-144x-580) | 580 W | +15 W, +0.6 pp | | [Renewsys DESERV Extreme 144X-585](https://comparepv.com/panel/renewsys-deserv-extreme-144x-585) | 585 W | +20 W, +0.8 pp | | [Renewsys DESERV Extreme 144X-590](https://comparepv.com/panel/renewsys-deserv-extreme-144x-590) | 590 W | +25 W, +1.0 pp | | [Renewsys DESERV Extreme 144X-595](https://comparepv.com/panel/renewsys-deserv-extreme-144x-595) | 595 W | +30 W, +1.2 pp | | [Renewsys DESERV Extreme 144X-600](https://comparepv.com/panel/renewsys-deserv-extreme-144x-600) | 600 W | +35 W, +1.4 pp | | [Renewsys DESERV Extreme 144X-605](https://comparepv.com/panel/renewsys-deserv-extreme-144x-605) | 605 W | +40 W, +1.6 pp | | [Renewsys DESERV Extreme 144X-610](https://comparepv.com/panel/renewsys-deserv-extreme-144x-610) | 610 W | +45 W, +1.7 pp | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +85 W, lighter, +3.3 pp | --- Source: https://comparepv.com/panel/renewsys-deserv-extreme-144x-565 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.
