The use of an MBB multi-busbar design allows for a more effective reduction in resistance losses and improved current flow, which translates into stable operation even in difficult lighting conditions. A key feature of this series is **high resistance to LID and LeTID degradation**, which guarantees long-term energy security and a faster return on investment for investors. These modules solve the problem of limited installation space, offering maximum power from every square meter of roof or ground. Thanks to thermal optimization, SpolarPV panels maintain an **excellent power temperature coefficient**, working efficiently during summer heat when standard cells lose performance. This product is primarily dedicated to professional solar farms and large enterprises focused on **maximizing yields from large areas**. Compared to the competition, this series stands out for its precise balance between innovative design and mechanical resistance to extreme snow and wind loads. By choosing SpolarPV SPV590-TM10-144, you gain confidence in the system's operation in the most demanding Polish climate. ## Notable figures - Efficiency of 22.5% matches the \*\*TOPCon 550-600W\*\* median - At 224.7 W/m² power density, roof space requirements are typical for \*\*TOPCon 550-600W\*\* panels - At -0.30%/°C, hot weather performance is typical for \*\*TOPCon 550-600W\*\* panels - 26.5 kg weight - 4.7 kg lighter than \*\*TOPCon 550-600W\*\* median (31.2 kg), reducing installation effort - Ranked #4576 out of 14005 panels for efficiency in the database ## Questions ### What warranty does the SpolarPV SPV590-TM10-144 series come with? The SPV590-TM10-144 series comes with a 12-year product warranty covering manufacturing defects and a 30-year linear power output warranty. This means SpolarPV guarantees the panels will maintain a specified performance level for three decades of operation. For commercial solar projects, this is one of the critical parameters ensuring financial security and reliable long-term energy yields. ### How does the TOPCon technology in the SPV590-TM10-144 differ from PERC, and why should I choose it? TOPCon (Tunnel Oxide Passivated Contact) technology used in the SPV590-TM10-144 delivers higher conversion efficiency and a better power temperature coefficient than conventional PERC. N-type TOPCon cells also inherently resist LID and LeTID degradation, resulting in more stable power output across the 30-year module lifetime. This advantage is especially significant in large commercial installations where every tenth of a percent in efficiency translates directly to financial returns. ### Are the SpolarPV SPV590-TM10-144 panels suitable for a large utility-scale solar farm? Yes, the SPV590-TM10-144 series is designed specifically for utility-scale solar farms and large commercial installations. A peak power of 590 Wp delivered by 144 half-cut cells in the 182 mm format maximizes energy production per square meter of array area. The reinforced mechanical structure supports extreme snow and wind loads typical of Polish and Central European climate conditions. ### How does the SpolarPV SPV590-TM10-144 perform during summer heat? Thanks to TOPCon technology and thermal optimization, the SPV590-TM10-144 panels exhibit a better power temperature coefficient than legacy PERC modules, meaning they lose proportionally less output during high-temperature conditions. In commercial installations in Poland, where cell temperatures can exceed 60°C in summer, this translates into measurably higher energy yields during the peak production season. ### What are LID and LeTID, and are the SPV590-TM10-144 panels resistant to them? LID (Light Induced Degradation) and LeTID (Light and Elevated Temperature Induced Degradation) are phenomena that cause permanent power loss in solar modules during the first months of operation. The SPV590-TM10-144, built on N-type TOPCon cells, demonstrates high resistance to both processes. This means the panel reaches its rated output almost immediately and maintains it throughout the entire 30-year power warranty period. ### Is SpolarPV a Tier 1 manufacturer, and can I trust the SPV590-TM10-144 panels for a large investment? SpolarPV is not currently listed on Tier 1 manufacturer rankings published by agencies such as BloombergNEF. The company is a Chinese ODM (Original Design Manufacturer), meaning panels may be produced under contract for various brands. Before purchasing, it is advisable to verify IEC certifications, third-party test lab reports, and distributor reviews. Tier 1 status is not a prerequisite for good product quality, but its absence warrants closer due diligence. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/SPV585-TM10-144-25fc87767fa4.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | -20 W, cooler, +2.3 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | -25 W, cooler, +2.1 pp | | [AIKO AIKO-A630-MAH72Dw](https://comparepv.com/panel/aiko-aiko-a630-mah72dw) | 630 W | +50 W, heavier, +1.9 pp | | [Longi Solar LR7-60HVHL-550M](https://comparepv.com/panel/longi-lr7-60hvhl-550m) | 550 W | Cooler, lighter, +1.9 pp | | [JA Solar JAT60S40-540/LR](https://comparepv.com/panel/ja-solar-jat60s40-540-lr) | 540 W | -40 W, cooler, +1.9 pp | | [SpolarPV SP525HM6-72L](https://comparepv.com/panel/spolarpv-sp525hm6-72l) | 525 W | -55 W, -2.2 pp, -5 yr warranty | | [SpolarPV SP530HM6-72L](https://comparepv.com/panel/spolarpv-sp530hm6-72l) | 530 W | -50 W, -2.0 pp, -5 yr warranty | | [SpolarPV SPV535-PM10-144](https://comparepv.com/panel/spolarpv-spv535-pm10-144) | 535 W | -45 W, hotter, -1.7 pp | | [SpolarPV SPV540-PM10-144](https://comparepv.com/panel/spolarpv-spv540-pm10-144) | 540 W | -40 W, hotter, -1.5 pp | | [SpolarPV SPV545-PM10-144](https://comparepv.com/panel/spolarpv-spv545-pm10-144) | 545 W | -35 W, hotter, -1.3 pp | | [SpolarPV SPV550-PM10-144](https://comparepv.com/panel/spolarpv-spv550-pm10-144) | 550 W | -30 W, hotter, -1.2 pp | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +70 W, cooler, +2.7 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | +65 W, cooler, +2.5 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | +60 W, cooler, +2.3 pp | | [AIKO AIKO-A635-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a635-mae72mw) | 635 W | +55 W, cooler, +2.1 pp | --- Source: https://comparepv.com/panel/spolarpv-spv580-tm10-144 Not in this file, on the page: the I-V and temperature curves lifted from the manufacturer's datasheet, a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
