The use of **monocrystalline PERC solar cells** enables efficient utilization of light even under less than ideal conditions, such as light cloud cover. Modules feature a **120-cell structure (half-cells)**, which helps reduce losses and offers better tolerance to partial shading compared to many conventional designs. In practice, this means more predictable energy production when roof features like chimneys, antennas, or periodic dirt accumulate. An additional advantage is the **tempered glass with anti-reflective coating**, which helps minimize reflections and improve light capture. The entire system is complemented by a **highly sealed junction box box**, important for installations in challenging weather conditions. This is the choice for companies, farms, and investors seeking to reduce energy costs and increase self-consumption without compromising on quality. ## Notable figures - Efficiency of 20.8% matches the \*\*PERC 550-600W\*\* median - Power density of 208.5 W/m² is 4.4 W/m² below \*\*PERC 550-600W\*\* median (212.9 W/m²) - needs more roof space - Temperature coefficient of -0.34%/°C matches the \*\*PERC 550-600W\*\* median - Ranked #10457 out of 14005 panels for efficiency in the database ## Questions ### What kind of installations are Talesun BISTAR TP8F60M / TP8F60M(H) panels best suited for? The TP8F60M series is designed for large rooftop areas and ground-mount installations where high power density per square meter matters most. With up to 605 Wp output and a large module format, it performs particularly well in commercial projects, on industrial and warehouse rooftops, and in agricultural or utility-scale solar farms where maximizing energy yield from limited mounting space is the priority. ### What is PERC technology in the TP8F60M cells, and does it actually improve energy yield? PERC (Passivated Emitter and Rear Cell) adds a passivation layer on the back of the cell that reflects unused light back into the silicon instead of losing it. This lets TP8F60M cells reach up to 21.4% efficiency and perform better under weaker sunlight, such as light cloud cover or early morning conditions, resulting in more stable energy production across the whole year. ### How do the half-cut cells in the TP8F60M differ from panels with full-size cells? The TP8F60M module uses 120 half-cut cells, which lowers the current flowing through the circuit and reduces resistive power losses by a few percent compared to full-cell panels. It also offers better tolerance to partial shading, for example when a chimney or antenna shadows only part of the panel, since the module is split into independent electrical sections that limit the impact on overall string output. ### What warranty does Talesun offer on the BISTAR TP8F60M series, and what does it cover? Talesun provides a 12-year product warranty covering material and workmanship defects, plus a 25-year power performance warranty guaranteeing a defined level of energy output over that period. This is standard among Tier 1 manufacturers and gives investors confidence in long-term return on investment, especially important for commercial projects financed through loans or leasing. ### Are TP8F60M panels bifacial, generating power from both sides of the module? No, the TP8F60M / TP8F60M(H) series is a monofacial panel line, optimized for standard rooftop and ground-mount installations with energy generation from the front side only. If an investor needs a bifacial solution, for example for a ground-mount installation over reflective light-colored ground, another series in Talesun's lineup dedicated to bifacial technology should be considered instead. ### Is Talesun a reliable Tier 1 manufacturer, and how does it compare to other Chinese brands? Yes, Talesun is classified as a Tier 1 manufacturer, indicating financial stability, in-house production lines, and a documented track record in bankable PV projects. The company is headquartered in China and supplies modules for commercial and industrial installations worldwide. Tier 1 status matters for project financing, since banks and insurers are more likely to accept panels from this category as security for long-term agreements. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/166845180163031d2b12a30-998f7de89c2a.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | Cooler, lighter, +4.0 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | +50 W, cooler, +4.0 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | Cooler, lighter, +3.8 pp | | [AIKO AIKO-A635-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a635-mae72mw) | 635 W | Cooler, +3.8 pp, +5 yr warranty | | [AIKO AIKO-A630-MAH72Dw](https://comparepv.com/panel/aiko-aiko-a630-mah72dw) | 630 W | Cooler, +3.6 pp, +5 yr warranty | | [Longi Solar LR7-60HVHL-550M](https://comparepv.com/panel/longi-lr7-60hvhl-550m) | 550 W | Cooler, 15 kg lighter, +3.6 pp | | [Talesun TP8F60M-585W](https://comparepv.com/panel/talesun-tp8f60m-585w) | 585 W | Very close match | | [Talesun TP8F60M-595W](https://comparepv.com/panel/talesun-tp8f60m-595w) | 595 W | Very close match | | [Talesun TP8F60M-600W](https://comparepv.com/panel/talesun-tp8f60m-600w) | 600 W | +10 W, +0.4 pp | | [Talesun TP8F60M-605W](https://comparepv.com/panel/talesun-tp8f60m-605w) | 605 W | +15 W, +0.6 pp | | [Gamko New Energy GKA210N120](https://comparepv.com/panel/gamko-new-energy-gka210n120) | 680 W | +90 W, +3.2 pp, +5 yr warranty | | [Gamko New Energy GKA210N120-675](https://comparepv.com/panel/gamko-new-energy-gka210n120-675) | 675 W | +85 W, +3.1 pp, +5 yr warranty | | [Q-SUN Solar QN-670HJT-01](https://comparepv.com/panel/q-sun-solar-qn-670hjt-01) | 670 W | +80 W, cooler, +2.9 pp | | [Gamko New Energy GKA210N120-670](https://comparepv.com/panel/gamko-new-energy-gka210n120-670) | 670 W | +80 W, +2.9 pp, +5 yr warranty | | [Q-SUN Solar QN-665HJT-01](https://comparepv.com/panel/q-sun-solar-qn-665hjt-01) | 665 W | +75 W, cooler, +2.7 pp | | [Gamko New Energy GKA210N120-665](https://comparepv.com/panel/gamko-new-energy-gka210n120-665) | 665 W | +75 W, +2.7 pp, +5 yr warranty | --- Source: https://comparepv.com/panel/talesun-tp8f60m-590w Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
