The use of **high-class silicon cells** allows for efficient electricity generation even in diffused light, which is crucial in variable weather conditions. This series stands out for its **exceptional mechanical durability**, achieved through a multi-layer lamination process that protects components from moisture-induced degradation. The compact dimensions of the modules make them indispensable in places with limited space, such as camper roofs, yachts, or autonomous street lighting systems. **Optimal voltage matching** for battery charging allows for a simplified design of the entire kit and a significant reduction in energy conversion losses. The use of an **anodized aluminum frame** and low-iron glass guarantees full resistance to strong winds and snow loads, distinguishing this product from less stable alternatives. The TPL S-36 effectively solves power supply problems in remote locations, offering operational stability for decades without the need for frequent maintenance. This is a professional solution for users building energy intake points, where the priority is proven reliability in all weather conditions. ## Notable figures - At 14.8% efficiency, this panel is 4.7pp below the \*\*PERC 0-400W\*\* median of 19.4% - 128.8 W/m² power density is 65.6 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 - At 5.8 kg, this panel is 14.7 kg lighter than \*\*PERC 0-400W\*\* median (20.5 kg) - easier handling during installation - #13851 for efficiency, #12345 for temperature performance out of 14005 panels ## Questions ### Is the TPL S-36 100Wp panel still available for purchase? The TPL S-36 series has been discontinued and is no longer actively manufactured. Only remaining distributor stock may still be available. Anyone planning to expand an existing installation should contact their supplier promptly to check remaining inventory, since once stock runs out a replacement panel with similar voltage characteristics will be needed. ### What warranty comes with the TPL S-36 100Wp panel? TPL Solar provides a 12-year product warranty covering material and workmanship defects, plus a 30-year linear power output warranty. This means the module should still deliver a significant share of its rated power after that period. Since the series is discontinued, warranty service may now be handled solely through the local distributor rather than the manufacturer directly. ### Is the TPL S-36 100Wp panel suitable for charging a 12V battery in a camper or on a boat? Yes, its 100Wp maximum power and compact module size make it a popular choice for 12V systems in campers, boats, and yachts. The panel's operating voltage is matched to typical PWM or MPPT charge controllers, simplifying wiring and reducing conversion losses when charging lead-acid or lithium batteries. ### What does PERC cell technology mean in the TPL S-36 and is it a real benefit? PERC (Passivated Emitter and Rear Cell) adds a passivation layer on the back of the cell that reflects unused light back into the silicon. In practice, this delivers higher conversion efficiency than standard cells, especially under diffuse or low-light conditions, which matters on cloudy days or with partial shading in off-grid setups. ### Is the TPL S-36 a bifacial solar panel? No, the TPL S-36 series is a monofacial module that generates power only from its front surface. It does not capture light reflected off the ground, so installers should focus on optimal tilt angle and south-facing orientation to maximize energy yield without a rear active surface. ### Can TPL S-36 panels withstand heavy snow load and strong wind? Yes, the module features an anodized aluminum frame and low-iron glass, providing sufficient structural rigidity for snow loads and resistance to strong wind gusts. Multi-layer lamination further protects the cells and wiring from moisture ingress, extending panel lifespan in harsh conditions such as remote or roadside installations. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/5872eb23a80cc-a1a5f620e49e.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Gamko New Energy GKA182M120W](https://comparepv.com/panel/gamko-new-energy-gka182m120w) | 120 W | +35 W, +8.2 pp | | [Gamko New Energy GKA182M135W](https://comparepv.com/panel/gamko-new-energy-gka182m135w) | 135 W | +50 W, +8.2 pp | | [Gamko New Energy GKA182M100W](https://comparepv.com/panel/gamko-new-energy-gka182m100w) | 100 W | +15 W, +8.2 pp | | [Gamko New Energy GKA182M110W](https://comparepv.com/panel/gamko-new-energy-gka182m110w) | 110 W | +25 W, +8.2 pp | | [JA Solar NS-100MH-36](https://comparepv.com/panel/ja-solar-ns-100mh-36) | 100 W | Cooler, +6.5 pp, -5 yr warranty | | [PolyCrown Solar Tech NS-100MH-36](https://comparepv.com/panel/polycrown-solar-tech-ns-100mh-36) | 100 W | Cooler, +6.5 pp, -5 yr warranty | | [Renesola YH120W-18M](https://comparepv.com/panel/renesola-yh120w-18m) | 120 W | +35 W, cooler, +4.9 pp | | [Easun Power YH100W-12M](https://comparepv.com/panel/easun-power-yh100w-12m) | 100 W | Hotter, lighter, +4.9 pp | | [Isola New Energy YH120W-18M](https://comparepv.com/panel/isola-new-energy-yh120w-18m) | 120 W | +35 W, cooler, +4.9 pp | | [Isola New Energy YH100W-12M](https://comparepv.com/panel/isola-new-energy-yh100w-12m) | 100 W | Hotter, lighter, +4.9 pp | | [TPL Solar TPL80S-36](https://comparepv.com/panel/tpl-solar-tpl80s-36) | 80 W | -0.2 pp | | [TPL Solar TPL90S-36](https://comparepv.com/panel/tpl-solar-tpl90s-36) | 90 W | +0.3 pp | | [TPL Solar TPL95S-36](https://comparepv.com/panel/tpl-solar-tpl95s-36) | 95 W | +10 W, +0.6 pp | | [TPL Solar TPL100S-36](https://comparepv.com/panel/tpl-solar-tpl100s-36) | 100 W | +15 W, +0.9 pp | | [Maxeon SPR-E-Flex-110](https://comparepv.com/panel/maxeon-spr-e-flex-110) | 110 W | Cooler, +2.2 pp, -25 yr warranty | | [Maxeon SPR-E-Flex-100](https://comparepv.com/panel/maxeon-spr-e-flex-100) | 100 W | Cooler, lighter, -25 yr warranty | --- Source: https://comparepv.com/panel/tpl-solar-tpl85s-36 Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
