The use of **large-area monocrystalline cells** allows for achieving high efficiency while maintaining the stability of electrical parameters in difficult weather conditions. The 72-cell design makes these modules an ideal choice for investors seeking to optimize installation costs on photovoltaic farms and large hall roofs. This series stands out for its **high resistance to the PID effect**, which directly translates into a longer system lifespan and minimization of energy losses over time. Thanks to the use of modern passivation technologies, TPLM-72 panels guarantee a **better temperature coefficient**, allowing for efficient operation even on hot days. What sets them apart from the competition is the exceptional frame rigidity and precise fit of components, which eliminates the risk of micro-cracks during transport and installation. By choosing this series, the user gains **industrial-scale reliability** and a product that effectively shortens the return on investment time thanks to high power density. It is a solid foundation for any renewable energy project where reliability and predictability of power production over decades matter. ## Notable figures - Efficiency of 16.5% is 2.9pp below the \*\*PERC 0-400W\*\* median (19.4%) - 165.4 W/m² power density is 28.8 W/m² below \*\*PERC 0-400W\*\* median (194.2 W/m²) - requires larger installation area - Temperature coefficient of -0.36%/°C matches the \*\*PERC 0-400W\*\* median - Weight of 23.0 kg is 2.5 kg above \*\*PERC 0-400W\*\* median (20.5 kg) - verify structural support - #13682 for efficiency, #12425 for temperature performance out of 14129 panels ## Questions ### What is the power output of TPL Solar TPLM-72 panels and what installations are they suited for? The TPLM-72 series reaches up to 320 Wp. Built on a 72-cell monocrystalline PERC layout, these modules are designed mainly for commercial and industrial installations - solar farms and large warehouse rooftops - where minimizing installation cost per watt over large areas is the priority. ### What warranty comes with TPLM-72 panels, and how does it compare to tier 1 manufacturers? TPL Solar provides a 12-year product warranty and a 30-year power output warranty, which is a standard coverage level for this module class. However, TPL Solar is not listed as a tier 1 manufacturer, which is worth considering when evaluating the manufacturer's long-term financial stability for future warranty claims. ### What is PERC technology in TPLM-72 panels, and does it improve efficiency? PERC (Passivated Emitter and Rear Cell) adds a passivation layer on the back of the cell that reflects unabsorbed photons back into the silicon structure. This gives TPLM-72 panels higher conversion efficiency and a better temperature coefficient than standard modules, resulting in more stable power output on hot days. ### Are TPLM-72 panels resistant to PID, and what does that mean in practice? Yes, the TPLM-72 series offers high resistance to PID (Potential Induced Degradation), the power loss caused by voltage differences between the cell and the frame. In practice, this means lower energy losses over time and more predictable power output throughout the entire 30-year power warranty period. ### Are TPLM-72 panels bifacial? No, the TPLM-72 series uses a standard monofacial construction rather than bifacial technology. This means the modules generate energy only from the front surface, which is typical for large rooftop and ground-mount installations where bifacial gains don't always justify the added cost. ### Where is TPL Solar based, and should that factor into a purchase decision? TPL Solar is headquartered in Pakistan. When choosing panels from a manufacturer outside the tier 1 category, it's worth checking the local distributor and warranty servicing terms in your country, since claims can take longer to resolve through longer supply chains compared to globally established brands with extensive support networks. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/5872ddf6c62bb-13969e72830e.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, +6.8 pp | | [PolyCrown Solar Tech NS-300MH-72](https://comparepv.com/panel/polycrown-solar-tech-ns-300mh-72) | 300 W | Cooler, lighter, +6.8 pp | | [Heckert Solar ZEUS 1.2 FullBlack 280W](https://comparepv.com/panel/heckert-solar-zeus-1-2-fullblack-280w) | 280 W | Cooler, lighter, +6.8 pp | | [JA Solar NS-330MH-80](https://comparepv.com/panel/ja-solar-ns-330mh-80) | 330 W | Cooler, lighter, +6.6 pp | | [PolyCrown Solar Tech NS-330MH-80](https://comparepv.com/panel/polycrown-solar-tech-ns-330mh-80) | 330 W | Cooler, lighter, +6.6 pp | | [Heckert Solar ZEUS 3.2 285WP FullBlack](https://comparepv.com/panel/heckert-solar-zeus-3-2-285wp-fullblack) | 285 W | Cooler, lighter, +6.6 pp | | [Gamko New Energy GKA182M285W](https://comparepv.com/panel/gamko-new-energy-gka182m285w) | 285 W | -35 W, lighter, +6.5 pp | | [Gamko New Energy GKA182M270W](https://comparepv.com/panel/gamko-new-energy-gka182m270w) | 270 W | -50 W, lighter, +6.5 pp | | [Gamko New Energy GKA182M300W](https://comparepv.com/panel/gamko-new-energy-gka182m300w) | 300 W | -20 W, lighter, +6.5 pp | | [TPL Solar TPL300P-72](https://comparepv.com/panel/tpl-solar-tpl300p-72) | 300 W | -20 W, -1.0 pp | | [TPL Solar TPL305M-72](https://comparepv.com/panel/tpl-solar-tpl305m-72) | 305 W | -15 W, -0.8 pp | | [TPL Solar TPL310M-72](https://comparepv.com/panel/tpl-solar-tpl310m-72) | 310 W | -10 W, -0.5 pp | | [TPL Solar TPL315M-72](https://comparepv.com/panel/tpl-solar-tpl315m-72) | 315 W | -0.3 pp | | [TPL Solar TPL315P -72](https://comparepv.com/panel/tpl-solar-tpl315p-72-1) | 315 W | -0.3 pp | | [Maxeon SPR-MAX7-475](https://comparepv.com/panel/maxeon-spr-max7-475) | 475 W | +155 W, +7.5 pp, +10 yr warranty | | [Maxeon SPR-MAX7-470](https://comparepv.com/panel/maxeon-spr-max7-470) | 470 W | +150 W, +7.2 pp, +10 yr warranty | --- Source: https://comparepv.com/panel/tpl-solar-tpl320m-72 Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
