# Talesun panels, *read off the datasheets*

Talesun Solar, a subsidiary of Zhongli Group, is a leading global photovoltaic manufacturer specializing in the development, manufacturing, and delivery of high-quality solar modules and integrated PV energy solutions. The company provides clean and affordable PV energy solutions for residential, commercial, and...

Everything below is computed from those 144 datasheets: no score out of ten, no ranking of brands against each other, and nothing a manufacturer can pay to change. Where Talesun does not publish a figure, it is left out of the average rather than assumed.


## The company

- **Founded:** 2010
- **Headquarters:** Suzhou, China
- **Annual capacity:** 5+ GW
- **Employees:** 501
- **Tier 1 bankable:** Yes (good)

Company facts, not datasheet figures. Tier 1 is a financier's bankability list, and says nothing about how a panel performs.


## Key figures


| Measure | Value | Note |
| --- | --- | --- |
| Panels | 144 | models in the database |
| Average efficiency | 22.1 % | across the catalogue |
| Best efficiency | 24.8 % (good) | their strongest module |
| Power range | 380-710 Wp | smallest to largest |
| Bifacial share | 59 % | 85 dual-sided models |
| Average warranty | 29 years | guaranteed output term |


## 01. The top of the range

The leaders of Talesun's own catalogue on the two figures a specification sheet leads with. Neither is a verdict: the most efficient module in a range is rarely the one that suits a given roof.

## 02. By what the array is for

Three cuts of the same catalogue, each ordered by efficiency inside its band. An empty column means the brand does not build for that case.

## 03. What the catalogue is made of

Shares are of the 144 modules in the database, counted once each. A power ladder of one module counts as its rungs, which is why a large catalogue is not the same as a wide one.

[Cell technology across the market](https://comparepv.com/stats/cell-technology)


### Cell technology

share of the catalogue


| # | Panel | share | panels |
| --- | --- | --- | --- |
|  | TOPCon | 43.8% | 63 |
|  | PERC | 35.4% | 51 |
|  | N-type | 11.8% | 17 |
|  | HJT | 5.6% | 8 |
|  | Unknown | 3.5% | 5 |

TOPCon accounts for 43.8% of the catalogue - 63 of 144 modules.


### Efficiency spread

share of the catalogue


| # | Panel | share | panels |
| --- | --- | --- | --- |
|  | \<20% | 3.5% | 5 |
|  | 20-21% | 16.7% | 24 |
|  | 21-22% | 22.2% | 32 |
|  | 22-23% | 29.9% | 43 |
|  | 23%+ | 27.8% | 40 |


## 04. Strengths and gaps

Both lists are derived from the figures above rather than written about the brand. A gap here is a gap in what is published, which is not always a gap in what is built.


### What this catalogue is good at

- **Strength:** Solid portfolio of 144 panels
- **Strength:** Tier 1 bankable manufacturer - recognized by major financial institutions
