Thanks to the use of 72 polycrystalline cells, these panels offer an excellent price-to-power ratio, making them an ideal choice for investors building solar farms and large industrial facilities. A key feature distinguishing this series is **high resistance to potential-induced degradation (PID)**, which guarantees stable system operation for decades, even in demanding weather conditions. The module design is based on multi-busbar technology, which minimizes resistive losses and improves current flow. TPL P-72 effectively addresses the profitability challenges of large projects by offering **reliability in harsh environmental conditions** and high mechanical resistance to snow and wind loads. Unlike standard residential solutions, this series focuses on **optimizing BOS system costs**, allowing for reduced expenditures on mounting structures and cabling. By choosing these panels, you gain **stability of electrical parameters**, which directly translates into a faster return on investment. This is a professional tool for the commercial sector, combining proven silicon technology with modern durability standards, outperforming the competition in the **industrial strength** category. ## Notable figures - At 17.0% efficiency, this panel is 4.8pp below the \*\*database\*\* median of 21.8% - At 170.1 W/m², this panel generates 48.0 W/m² less per unit area than \*\*database\*\* median (218.1 W/m²) - -0.36%/°C temperature coefficient - 0.06pp worse than \*\*database\*\* median (-0.30%/°C), expect higher hot weather losses - At 23.0 kg, this panel is 3.5 kg lighter than \*\*database\*\* median (26.5 kg) - easier handling during installation - In the top 96% for efficiency among all N-type panels ## Questions ### How much power does a panel from the TPL P-72 series generate? TPL P-72 modules reach a maximum power output of up to 340 Wp. Thanks to 72 polycrystalline cells and multi-busbar technology, these panels deliver stable energy yield with a solid price-to-power ratio, which matters most in utility-scale projects where total installed capacity outweighs single-module compactness. ### What warranty applies to the TPL P-72 Series panels? The manufacturer offers a 12-year product warranty and a 30-year linear power output warranty. This means that after three decades the panel should still generate a significant share of its initial nominal power. It's worth checking service terms with a local distributor, since the manufacturer is based in Pakistan and does not hold Tier 1 status. ### How does PID resistance in TPL P-72 differ from standard poly panels? The P-72 series features enhanced potential-induced degradation (PID) resistance, limiting power loss caused by high system voltages in large series-connected arrays. This is a key advantage in solar farms, where module strings operate at high DC voltage, and standard polycrystalline panels without PID protection can degrade faster than the rated performance curve. ### Are TPL P-72 panels suitable for large solar farms, or more for residential use? The P-72 series is designed for utility-scale installations and industrial sites rather than typical single-family rooftops. The construction focuses on BoS cost optimization, reducing spending on mounting structures and cabling across large numbers of modules, which matters far less in small residential systems. ### Does PERC technology in TPL P-72 panels improve efficiency compared to regular poly cells? Yes, the PERC cells used in the P-72 series include an additional rear passivation layer that reflects unused light back into the silicon structure. This increases conversion efficiency compared to standard polycrystalline cells without PERC, improving energy yield especially in low-light conditions such as early morning or late afternoon. ### How much mechanical load resistance do TPL P-72 panels have against snow and wind? The P-72 module construction provides high mechanical load resistance against snow and wind, making the panels suitable for installations in demanding climates. The frame design and multi-busbar technology reduce the risk of microcracks under heavy loads, contributing to stable performance throughout the warranty period. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/5b90903e64a27-25e9035ec130.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [SunLink LNSK-340M](https://comparepv.com/panel/sunlink-lnsk-340m) | 340 W | Lighter, +3.0 pp, -5 yr warranty | | [Canadian Solar CS3K-330P](https://comparepv.com/panel/canadian-solar-cs3k-330p) | 330 W | Lighter, +2.9 pp, -5 yr warranty | | [Canadian Solar CS3K-335MB-AG](https://comparepv.com/panel/canadian-solar-cs3k-335mb-ag) | 335 W | +2.9 pp | | [SunLink LNSK-335M](https://comparepv.com/panel/sunlink-lnsk-335m) | 335 W | Lighter, +2.7 pp, -5 yr warranty | | [Canadian Solar CS3L-365P](https://comparepv.com/panel/canadian-solar-cs3l-365p) | 365 W | +35 W, +2.7 pp, -5 yr warranty | | [Canadian Solar CS3K-325P](https://comparepv.com/panel/canadian-solar-cs3k-325p) | 325 W | Lighter, +2.6 pp, -5 yr warranty | | [Canadian Solar CS3L-360P](https://comparepv.com/panel/canadian-solar-cs3l-360p) | 360 W | +30 W, +2.5 pp, -5 yr warranty | | [SunLink LNSK-330M](https://comparepv.com/panel/sunlink-lnsk-330m) | 330 W | Lighter, +2.4 pp, -5 yr warranty | | [TPL Solar TPL300P-72](https://comparepv.com/panel/tpl-solar-tpl300p-72) | 300 W | -30 W, -1.5 pp | | [TPL Solar TPL305M-72](https://comparepv.com/panel/tpl-solar-tpl305m-72) | 305 W | -25 W, -1.3 pp | | [TPL Solar TPL310M-72](https://comparepv.com/panel/tpl-solar-tpl310m-72) | 310 W | -20 W, -1.0 pp | | [TPL Solar TPL315M-72](https://comparepv.com/panel/tpl-solar-tpl315m-72) | 315 W | -15 W, -0.8 pp | | [TPL Solar TPL315P -72](https://comparepv.com/panel/tpl-solar-tpl315p-72-1) | 315 W | -15 W, -0.8 pp | | [TPL Solar TPL320M-72](https://comparepv.com/panel/tpl-solar-tpl320m-72) | 320 W | -10 W, -0.5 pp | | [Maxeon SPR-MAX7-475](https://comparepv.com/panel/maxeon-spr-max7-475) | 475 W | +145 W, +7.0 pp, +10 yr warranty | | [Maxeon SPR-MAX7-470](https://comparepv.com/panel/maxeon-spr-max7-470) | 470 W | +140 W, +6.7 pp, +10 yr warranty | --- Source: https://comparepv.com/panel/tpl-solar-tpl330p-72-1 Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
