Thanks to the use of 36 polycrystalline cells, these modules work perfectly with 12V batteries, making them an indispensable element in campers, yachts, and autonomous street lighting. The use of **high-permeability tempered glass** and an extremely durable anodized aluminum frame guarantees full resistance to harsh weather conditions, including strong winds and snow accumulation. This series stands out with an **optimal price-to-performance ratio**, allowing for a fast return on investment in locations without direct access to the power grid. Precise **lamination with high-quality EVA film** effectively protects the silicon cells against moisture and premature degradation, ensuring stable operation over many years of use. Unlike standard large-format panels, the TPL P-36 series offers **exceptionally compact dimensions and easy installation**, effectively solving the problem of limited space on vehicle roofs or small technical structures. Solid construction and proven polycrystalline technology make it the first-choice product for installers and users who value a substantive approach to the durability of photovoltaic components. ## Notable figures - Module efficiency of 14.6% is 4.8pp below average for \*\*PERC 0-400W\*\* panels (median: 19.4%) - Power density of 146.2 W/m² is 48.0 W/m² below \*\*PERC 0-400W\*\* median (194.2 W/m²) - needs more roof space - At -0.36%/°C, hot weather performance is typical for \*\*PERC 0-400W\*\* panels - Weight of 10.8 kg (9.7 kg below \*\*PERC 0-400W\*\* median of 20.5 kg) allows easier transport and roof mounting - In the top 99% for efficiency among all PERC panels ## Questions ### What kind of installation is the TPL P-36 160 Wp solar panel suitable for? The TPL P-36 160 Wp panel is designed for low-voltage 12V off-grid systems. It works well in RVs, boats, standalone home power setups, autonomous street lighting, and small installations powering pumps or monitoring equipment. Its compact size makes it easy to mount in tight spaces where standard large-format panels won't fit. ### How does the PERC cell technology in the TPL P-36 differ from standard polycrystalline cells? PERC cells have an additional passivation layer on the rear surface that reflects unused photons back into the cell, boosting efficiency compared to standard poly cells. As a result, the TPL P-36 achieves a better power-to-area ratio than older polycrystalline designs, while still relying on a proven and cost-effective technology base. ### What warranty comes with TPL P-36 panels, and can you trust a manufacturer based in Pakistan? TPL Solar offers a 12-year product warranty and a 30-year linear power output warranty. These are standard market terms, though TPL Solar is not a tier 1 manufacturer, so it's worth checking your local distributor and warranty service conditions before committing to a larger installation. ### Is the TPL P-36 panel bifacial, generating power from both sides? No, the TPL P-36 series is a monofacial panel with no bifacial function. Energy is harvested only from the front side, which is typical for panels of this size and purpose, where low cost and easy installation take priority over maximizing gains from reflected light. ### Can TPL P-36 panels withstand strong wind and heavy snow load on an RV roof? Yes, the modules feature an anodized aluminum frame and high-transmittance tempered glass, providing resistance to wind and snow loads in line with standard PV norms. Additionally, the EVA lamination protects the silicon cells from moisture, which matters under variable weather conditions during travel or boat use. ### How many TPL P-36 panels are needed to charge a 12V battery in an off-grid system? A single 160 Wp panel is enough to maintain charging for one 12V battery under moderate power demand, such as in a small lighting system. For higher demand, like an RV with a fridge and electronics, connecting several panels in parallel is recommended to increase total charging current without raising the system voltage. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/20170222102321-2152-b4cc73822fd8.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Resun Solar RS7E-195P](https://comparepv.com/panel/resun-solar-rs7e-195p) | 195 W | +50 W, hotter, +3.2 pp | | [JA Solar MYP3036-180](https://comparepv.com/panel/ja-solar-myp3036-180) | 180 W | +35 W, +3.0 pp, -5 yr warranty | | [MY Solar MYP3036-180](https://comparepv.com/panel/my-solar-myp3036-180) | 180 W | +35 W, +3.0 pp, -5 yr warranty | | [Resun Solar RS7E-190P](https://comparepv.com/panel/resun-solar-rs7e-190p) | 190 W | +45 W, hotter, +2.8 pp | | [JA Solar MYP3036-175](https://comparepv.com/panel/ja-solar-myp3036-175) | 175 W | +30 W, +2.5 pp, -5 yr warranty | | [MY Solar MYP3036-175](https://comparepv.com/panel/my-solar-myp3036-175) | 175 W | +30 W, +2.5 pp, -5 yr warranty | | [MY Solar MYM2036-170](https://comparepv.com/panel/my-solar-mym2036-170) | 170 W | +25 W, +2.5 pp, -5 yr warranty | | [Resun Solar RS7E-185P](https://comparepv.com/panel/resun-solar-rs7e-185p) | 185 W | +40 W, hotter, +2.3 pp | | [Waaree WS-195 /24V](https://comparepv.com/panel/waaree-ws-195-24v) | 195 W | +50 W, +2.1 pp, -20 yr warranty | | [TPL Solar TPL135P-36](https://comparepv.com/panel/tpl-solar-tpl135p-36) | 135 W | -10 W, -1.0 pp | | [TPL Solar TPL140M-36](https://comparepv.com/panel/tpl-solar-tpl140m-36) | 140 W | -0.5 pp | | [TPL Solar TPL150M-36](https://comparepv.com/panel/tpl-solar-tpl150m-36) | 150 W | +0.5 pp | | [TPL Solar TPL155M-36](https://comparepv.com/panel/tpl-solar-tpl155m-36) | 155 W | +10 W, +1.0 pp | | [TPL Solar TPL160P-36](https://comparepv.com/panel/tpl-solar-tpl160p-36) | 160 W | +15 W, +1.5 pp | | [Heckert Solar ZEUS 1.2 FullBlack 280W](https://comparepv.com/panel/heckert-solar-zeus-1-2-fullblack-280w) | 280 W | +135 W, cooler, +8.7 pp | | [Gamko New Energy GKA182M285W](https://comparepv.com/panel/gamko-new-energy-gka182m285w) | 285 W | +140 W, +8.4 pp | --- Source: https://comparepv.com/panel/tpl-solar-tpl145p-36 Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
