Their main advantage is the use of 48 cells, which allows for **high power density while maintaining compact dimensions**, often impossible to achieve using standard panels with a larger number of cells. Thanks to **high-efficiency polycrystalline cell** technology, this series exhibits excellent efficiency in diffuse light conditions, which is crucial for regional latitudes and variable weather. These panels effectively solve installation problems on yachts, campers, and small garage roofs where traditional modules are simply too large. A solid construction based on a reinforced aluminum frame ensures **above-average resistance to snow and wind loads**, guaranteeing system reliability for many years. They are distinguished from competing solutions by their exceptional lightness, which significantly reduces the costs of supporting structures and simplifies logistics. It is the ideal **choice for investors focused on full energy independence** in off-grid systems and wherever the priority is precisely matching power to the available area. By choosing the TPL P-48, you gain a proven energy source that combines industrial durability with high aesthetic standards, ensuring stable yields and **maximum use of every square meter** of your installation. ## Notable figures - Efficiency of 14.5% is 4.9pp below the \*\*PERC 0-400W\*\* median (19.4%) - 145.1 W/m² power density is 49.1 W/m² below \*\*PERC 0-400W\*\* median (194.2 W/m²) - requires larger installation area - At -0.36%/°C, hot weather performance is typical for \*\*PERC 0-400W\*\* panels - 15.0 kg weight - 5.5 kg lighter than \*\*PERC 0-400W\*\* median (20.5 kg), reducing installation effort - #14005 for efficiency, #12425 for temperature performance out of 14129 panels ## Questions ### Is the TPL P-48 series still available for purchase? No, production of the TPL P-48 series has ended and the panels are discontinued by manufacturer TPL Solar. Availability is now limited to remaining distributor stock or the secondary market. When planning to expand an existing installation, check with your dealer beforehand whether the model is still in stock, since matching modules won't be available once inventory runs out. ### What applications are TPL P-48 215 Wp panels best suited for? With 48 cells and compact dimensions, TPL P-48 modules work well where mounting space is limited, such as yachts, campervans, small garage roofs, and off-grid home systems. At 215 Wp, output is lower than standard residential panels, but for this class of application the priority is fitting the footprint rather than maximizing yield per square meter. ### What cell technology does the TPL P-48 use and how does it compare to TOPCon? The TPL P-48 series uses polycrystalline PERC cells, an older technology than the TOPCon or HJT cells found in today's top-tier panels. PERC delivers solid efficiency and performs well under diffuse light, but it falls short of newer technologies in peak efficiency and long-term power degradation. It's a proven, more affordable solution, though no longer cutting-edge. ### What warranty comes with TPL P-48 panels, and is it reliable given the discontinuation? The manufacturer provides a 12-year product warranty and a 30-year linear power warranty. Since the series has been discontinued, it's worth confirming with the seller whether TPL Solar or a local distributor still honors the warranty, as ending production can affect future service availability and access to replacement parts. ### Are TPL P-48 panels bifacial, and would that boost their output? No, the TPL P-48 series is monofacial, generating power only from the front surface. This means no extra gain from reflected light hitting the rear side, as with bifacial panels. For small installations like yachts or garage roofs this matters little, since those setups rarely provide the conditions needed to capture meaningful albedo gain anyway. ### Is TPL Solar a tier 1 manufacturer, and does that matter when choosing panels? No, TPL Solar, headquartered in Pakistan, is not listed as a tier 1 manufacturer. Tier 1 status mainly reflects financial stability and production scale rather than panel quality directly, but for buyers it does imply somewhat higher risk around long-term warranty support, especially for the already discontinued P-48 series. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/20170222102803-5834-be056e1a9c60.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Resun Solar RS7E-205P](https://comparepv.com/panel/resun-solar-rs7e-205p) | 205 W | Hotter, lighter, +4.3 pp | | [Resun Solar RS7E-200P](https://comparepv.com/panel/resun-solar-rs7e-200p) | 200 W | Hotter, lighter, +3.8 pp | | [Resun Solar RS7E-195P](https://comparepv.com/panel/resun-solar-rs7e-195p) | 195 W | Hotter, lighter, +3.3 pp | | [JA Solar MYP3036-180](https://comparepv.com/panel/ja-solar-myp3036-180) | 180 W | Lighter, +3.1 pp, -5 yr warranty | | [MY Solar MYP3036-180](https://comparepv.com/panel/my-solar-myp3036-180) | 180 W | Lighter, +3.1 pp, -5 yr warranty | | [JA Solar MYP3048-235](https://comparepv.com/panel/ja-solar-myp3048-235) | 235 W | +45 W, +3.0 pp, -5 yr warranty | | [MY Solar MYP3048-235](https://comparepv.com/panel/my-solar-myp3048-235) | 235 W | +45 W, +3.0 pp, -5 yr warranty | | [Resun Solar RS7E-190P](https://comparepv.com/panel/resun-solar-rs7e-190p) | 190 W | Hotter, lighter, +2.9 pp | | [JA Solar MYP3048-230](https://comparepv.com/panel/ja-solar-myp3048-230) | 230 W | +40 W, +2.7 pp, -5 yr warranty | | [JA Solar MYP3036-175](https://comparepv.com/panel/ja-solar-myp3036-175) | 175 W | Lighter, +2.7 pp, -5 yr warranty | | [TPL Solar TPL195P-48](https://comparepv.com/panel/tpl-solar-tpl195p-48) | 195 W | +0.4 pp | | [TPL Solar TPL200P-48](https://comparepv.com/panel/tpl-solar-tpl200p-48) | 200 W | +10 W, +0.8 pp | | [TPL Solar TPL205P-48](https://comparepv.com/panel/tpl-solar-tpl205p-48) | 205 W | +15 W, +1.2 pp | | [TPL Solar TPL210P-48](https://comparepv.com/panel/tpl-solar-tpl210p-48) | 210 W | +20 W, +1.5 pp | | [TPL Solar TPL215M-48](https://comparepv.com/panel/tpl-solar-tpl215m-48) | 215 W | +25 W, +1.9 pp | | [JA Solar MYM3048-265](https://comparepv.com/panel/ja-solar-mym3048-265) | 265 W | +75 W, +5.3 pp, -5 yr warranty | --- Source: https://comparepv.com/panel/tpl-solar-tpl190p-48 Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
