This design makes them an ideal choice for **commercial projects and solar farms**, allowing for a significant reduction in the number of mounting components and cabling while maintaining impressive overall efficiency. The use of modern technologies, such as **half-cut cells (Half-Cut)** and advanced multi-busbar connections, effectively minimizes energy losses resulting from internal resistance and point shading. This series stands out for its exceptional **resistance to potential-induced degradation (PID)**, which, combined with a 30-year linear power warranty, makes it a safe and predictable foundation for long-term business ventures. TPL M-72 panels perform excellently in demanding environmental conditions, offering certified resistance to mechanical loads of 5400 Pa and stable operation across a wide range of temperatures. They effectively address the issue of efficiency loss in low-light conditions, ensuring **maximum energy yield** even on cloudy days, which is crucial in Polish weather conditions. This is a professional solution for demanding investors seeking the perfect balance between innovative technology, component durability, and large-scale industrial profitability. ## Notable figures - Efficiency of 17.5% is 1.9pp below the \*\*PERC 0-400W\*\* median (19.4%) - Power density of 175.2 W/m² is 19.0 W/m² below \*\*PERC 0-400W\*\* median (194.2 W/m²) - needs more roof space - Temperature coefficient of -0.36%/°C matches the \*\*PERC 0-400W\*\* median - At 23.0 kg, this panel is 2.5 kg heavier than the \*\*PERC 0-400W\*\* median (20.5 kg) - more demanding for installation crews - #13454 for efficiency, #12425 for temperature performance out of 14129 panels ## Questions ### What is the maximum power output of the TPL M-72 panel and which installations does it suit best? TPL M-72 panels reach a maximum power output of 350 Wp using 72 monocrystalline PERC cells. With increased power density and half-cut technology, they are primarily suited for commercial projects and utility-scale PV farms, where reducing the number of modules, cabling, and mounting components matters while maintaining high overall system efficiency. ### How does the PERC technology used in the TPL M-72 differ from standard monocrystalline cells? PERC cells feature an additional passivation layer on the rear side that reflects unused photons back into the cell, boosting energy yield. Combined with half-cut technology and multi-busbar connections in the M-72 series, this reduces losses from internal resistance and partial shading, improving efficiency compared to older cell designs. ### What warranty comes with TPL M-72 panels, and is it competitive? TPL Solar provides a 12-year product warranty along with a 30-year linear power output warranty. This warranty structure is in line with market standards for modern PERC modules and gives investors a predictable return over the long-term horizon typical of commercial and utility-scale PV projects. ### Do TPL M-72 panels perform well in Polish weather conditions, with low irradiance and cold temperatures? Yes, TPL M-72 panels are certified for stable operation across a wide temperature range and deliver good energy yield even under diffuse light, which matters on the frequently overcast days typical of Poland's climate. They also withstand mechanical loads up to 5400 Pa, ensuring resistance to snow and strong wind. ### Are TPL M-72 panels resistant to PID degradation, and what does that mean in practice? Yes, the TPL M-72 series offers enhanced resistance to potential-induced degradation (PID), a phenomenon causing gradual power loss due to voltage differences between the cells and the frame. This feature helps the panels maintain stable output throughout their service life, directly supporting the 30-year power warranty. ### Is TPL Solar a Tier 1 manufacturer, and is it worth investing in panels outside the top bracket? TPL Solar, headquartered in Pakistan, does not currently hold Tier 1 status under the Bloomberg NEF classification. This doesn't mean lower technical quality - the M-72 series offers proven PERC and half-cut technologies plus solid warranties, though institutional investors should verify project bankability with their financing partner. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/5c25dc3d676fe-493afae64266.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [JA Solar NS-300MH-72](https://comparepv.com/panel/ja-solar-ns-300mh-72) | 300 W | Cooler, lighter, +5.8 pp | | [PolyCrown Solar Tech NS-300MH-72](https://comparepv.com/panel/polycrown-solar-tech-ns-300mh-72) | 300 W | Cooler, lighter, +5.8 pp | | [JA Solar NS-330MH-80](https://comparepv.com/panel/ja-solar-ns-330mh-80) | 330 W | Cooler, lighter, +5.6 pp | | [PolyCrown Solar Tech NS-330MH-80](https://comparepv.com/panel/polycrown-solar-tech-ns-330mh-80) | 330 W | Cooler, lighter, +5.6 pp | | [Gamko New Energy GKA182M300W](https://comparepv.com/panel/gamko-new-energy-gka182m300w) | 300 W | -40 W, lighter, +5.5 pp | | [Gamko New Energy GKA210M320W](https://comparepv.com/panel/gamko-new-energy-gka210m320w) | 320 W | -20 W, lighter, +5.5 pp | | [Gamko New Energy GKA210M340W](https://comparepv.com/panel/gamko-new-energy-gka210m340w) | 340 W | Lighter, +5.5 pp | | [Gamko New Energy GKA210M360W](https://comparepv.com/panel/gamko-new-energy-gka210m360w) | 360 W | +20 W, lighter, +5.5 pp | | [Gamko New Energy GKA210M380W (1/4\*4\*38)](https://comparepv.com/panel/gamko-new-energy-gka210m380w-1-4-4-38) | 380 W | +40 W, lighter, +5.5 pp | | [Gamko New Energy GKA210M380W (1/2\*4\*19)](https://comparepv.com/panel/gamko-new-energy-gka210m380w-1-2-4-19) | 380 W | +40 W, lighter, +5.5 pp | | [TPL Solar TPL300P-72](https://comparepv.com/panel/tpl-solar-tpl300p-72) | 300 W | -40 W, -2.0 pp | | [TPL Solar TPL305M-72](https://comparepv.com/panel/tpl-solar-tpl305m-72) | 305 W | -35 W, -1.7 pp | | [TPL Solar TPL310M-72](https://comparepv.com/panel/tpl-solar-tpl310m-72) | 310 W | -30 W, -1.5 pp | | [TPL Solar TPL315M-72](https://comparepv.com/panel/tpl-solar-tpl315m-72) | 315 W | -25 W, -1.2 pp | | [TPL Solar TPL315P -72](https://comparepv.com/panel/tpl-solar-tpl315p-72-1) | 315 W | -25 W, -1.2 pp | | [TPL Solar TPL320M-72](https://comparepv.com/panel/tpl-solar-tpl320m-72) | 320 W | -20 W, -1.0 pp | | [Maxeon SPR-MAX7-475](https://comparepv.com/panel/maxeon-spr-max7-475) | 475 W | +135 W, +6.5 pp, +10 yr warranty | --- Source: https://comparepv.com/panel/tpl-solar-tpl340m-72 Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
