# Longi Solar panels, *read off the datasheets*

LONGi Green Energy Technology Co., Ltd. is a world-leading solar technology company that manufactures monocrystalline silicon wafers and modules. The company is committed to providing high-efficiency and reliable clean energy solutions for large-scale power plants, various industries, and households. LONGi aims to...

Everything below is computed from those 255 datasheets: no score out of ten, no ranking of brands against each other, and nothing a manufacturer can pay to change. Where Longi Solar does not publish a figure, it is left out of the average rather than assumed.


## The company

- **Founded:** 2000
- **Headquarters:** Xi'an, Shaanxi, China
- **Annual capacity:** 85-90 GW
- **Employees:** 37,853
- **Listed:** Shanghai Stock Exchange: 601012
- **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 | 255 | models in the database |
| Average efficiency | 22.6 % | across the catalogue |
| Best efficiency | 25.0 % (good) | their strongest module |
| Power range | 100-670 Wp | smallest to largest |
| Bifacial share | 40 % | 101 dual-sided models |
| Average warranty | 28 years | guaranteed output term |


## 01. The top of the range

The leaders of Longi Solar'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 255 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 |
| --- | --- | --- | --- |
|  | N-type | 42.0% | 107 |
|  | Unknown | 21.6% | 55 |
|  | PERC | 20.0% | 51 |
|  | Back Contact | 16.5% | 42 |

N-type accounts for 42.0% of the catalogue - 107 of 255 modules.


### Efficiency spread

share of the catalogue


| # | Panel | share | panels |
| --- | --- | --- | --- |
|  | \<20% | 1.2% | 3 |
|  | 20-21% | 10.2% | 26 |
|  | 21-22% | 18.4% | 47 |
|  | 22-23% | 27.5% | 70 |
|  | 23%+ | 42.7% | 109 |


## 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:** Extensive portfolio of 255 panels across multiple series
- **Strength:** Tier 1 bankable manufacturer - recognized by major financial institutions
- **Strength:** High-efficiency panels available (up to 25.0%)
- **Strength:** Strong warranty coverage averaging 28 years
- **Strength:** High-power panels available (up to 670W) for commercial applications
- **Strength:** Established manufacturer with 26+ years of experience
- **Strength:** Large-scale production capacity of 85-90 GW


### Where it is thin

- **Watch out:** Limited adoption of latest cell technologies (TOPCon/HJT)
