These panels utilize advanced **high-efficiency silicon cells**, allowing for stable power production even in conditions of limited sunlight or diffused light. The module design is based on a **reinforced anodized aluminum frame**, which guarantees exceptional resistance to extreme mechanical loads, such as strong wind or heavy snow. This series stands out from the competition with its excellent **resistance to potential-induced degradation (PID)**, which significantly extends the lifespan of the components and ensures yield predictability over a very long time horizon. It is an ideal choice for investors looking for reliable panels to power autonomous street lighting, monitoring systems, or recreational vehicles. Thanks to the use of technology that minimizes energy losses at the junctions, TPL M-36 modules offer an **excellent temperature coefficient**, which directly translates into efficient operation on hot days. By choosing this series, the user receives a product that is fully **resistant to harsh environmental conditions**, including salt mist and ammonia, making it an extremely versatile and durable solution for demanding technical applications. ## Notable figures - Efficiency of 14.1% is 5.3pp below the \*\*PERC 0-400W\*\* median (19.4%) - 141.2 W/m² power density is 53.2 W/m² below \*\*PERC 0-400W\*\* median (194.4 W/m²) - requires larger installation area - Temperature coefficient of -0.36%/°C matches the \*\*PERC 0-400W\*\* median - 10.8 kg weight - 9.7 kg lighter than \*\*PERC 0-400W\*\* median (20.5 kg), reducing installation effort - #13912 for efficiency, #12345 for temperature performance out of 14005 panels ## Questions ### Is the TPL M-36 series still available for purchase? The TPL M-36 series has been discontinued and is no longer offered as a current model in the TPL Solar catalog. Panels may still be found through distributors as remaining stock or on the secondary market. Anyone planning to expand an existing installation should expect limited availability of identical modules and consider compatible alternatives with similar specifications. ### What applications is the 165 Wp TPL M-36 panel suited for? The 165 Wp TPL M-36 panel was designed for small-scale installations and off-grid systems where a compact module footprint matters. It works well for powering street lighting, monitoring systems, RVs, and campers, as well as other mobile applications where stable energy output within limited installation space is the priority. ### What warranty comes with TPL M-36 panels, and is it competitive? The manufacturer offers a 12-year product warranty and a 30-year power performance warranty. This is standard for PERC-based modules on the market, though shorter than the 15-25 year product warranties offered by leading tier 1 manufacturers. It's worth verifying warranty terms with the local distributor, since TPL Solar is a non-tier-1 manufacturer. ### How does the PERC technology in TPL M-36 differ from standard cells? PERC (Passivated Emitter and Rear Cell) technology adds a passivation layer on the back of the cell that reflects unused light back into the cell, increasing conversion efficiency. This allows TPL M-36 panels to perform better under diffuse light and partial cloud cover compared to modules built on older standard cell technology, which matters under variable sunlight conditions. ### Is the TPL M-36 a bifacial panel, and what does that mean in practice? No, the TPL M-36 series uses monofacial panels rather than bifacial ones. This means they generate power only from irradiance hitting the front surface, unlike bifacial modules that also capture light reflected off the ground. For the small off-grid installations this series targets, monofacial construction is sufficient and keeps module cost lower. ### Can TPL M-36 panels withstand harsh conditions like coastal air or strong wind? Yes, the modules feature a reinforced anodized aluminum frame rated for extreme mechanical loads, including strong wind and snow accumulation. The panels also resist salt mist and ammonia corrosion, making them a suitable choice for coastal installations and sites near agricultural facilities where standard modules would corrode more quickly. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/586f5db90a9fa-d88db2a44b17.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Gamko New Energy GKA182M150W](https://comparepv.com/panel/gamko-new-energy-gka182m150w) | 150 W | +10 W, lighter, +8.9 pp | | [Gamko New Energy GKA182M160W](https://comparepv.com/panel/gamko-new-energy-gka182m160w) | 160 W | +20 W, lighter, +8.9 pp | | [Gamko New Energy GKA182M180W](https://comparepv.com/panel/gamko-new-energy-gka182m180w) | 180 W | +40 W, lighter, +8.9 pp | | [Gamko New Energy GKA182M120W](https://comparepv.com/panel/gamko-new-energy-gka182m120w) | 120 W | -20 W, lighter, +8.9 pp | | [Gamko New Energy GKA182M135W](https://comparepv.com/panel/gamko-new-energy-gka182m135w) | 135 W | Lighter, +8.9 pp | | [Gamko New Energy GKA182M100W](https://comparepv.com/panel/gamko-new-energy-gka182m100w) | 100 W | -40 W, lighter, +8.9 pp | | [Gamko New Energy GKA182M110W](https://comparepv.com/panel/gamko-new-energy-gka182m110w) | 110 W | -30 W, lighter, +8.9 pp | | [JA Solar NS-100MH-36](https://comparepv.com/panel/ja-solar-ns-100mh-36) | 100 W | Cooler, lighter, +7.2 pp | | [PolyCrown Solar Tech NS-100MH-36](https://comparepv.com/panel/polycrown-solar-tech-ns-100mh-36) | 100 W | Cooler, lighter, +7.2 pp | | [Centro Energy CE-180M60](https://comparepv.com/panel/centro-energy-ce-180m60) | 180 W | Hotter, +6.4 pp, -5 yr warranty | | [TPL Solar TPL135P-36](https://comparepv.com/panel/tpl-solar-tpl135p-36) | 135 W | -0.5 pp | | [TPL Solar TPL145M-36](https://comparepv.com/panel/tpl-solar-tpl145m-36) | 145 W | +0.5 pp | | [TPL Solar TPL150M-36](https://comparepv.com/panel/tpl-solar-tpl150m-36) | 150 W | +10 W, +1.0 pp | | [TPL Solar TPL155M-36](https://comparepv.com/panel/tpl-solar-tpl155m-36) | 155 W | +15 W, +1.5 pp | | [TPL Solar TPL160P-36](https://comparepv.com/panel/tpl-solar-tpl160p-36) | 160 W | +20 W, +2.0 pp | | [Heckert Solar ZEUS 1.2 FullBlack 280W](https://comparepv.com/panel/heckert-solar-zeus-1-2-fullblack-280w) | 280 W | +140 W, cooler, +9.2 pp | --- Source: https://comparepv.com/panel/tpl-solar-tpl140m-36 Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
