# LG panels, *read off the datasheets*

LG Electronics is a South Korean multinational electronics company. Founded in 1958, LG is a global leader and technology innovator in consumer electronics, mobile communications, and home appliances. Although LG officially closed its solar panel business in 2022, the company continues to...

Everything below is computed from those 24 datasheets: no score out of ten, no ranking of brands against each other, and nothing a manufacturer can pay to change. Where LG does not publish a figure, it is left out of the average rather than assumed.


## The company

- **Founded:** 1958
- **Headquarters:** Seoul, South Korea
- **Employees:** 74,000+
- **Listed:** KRX: 066570

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 | 24 | models in the database |
| Average efficiency | 20.7 % | across the catalogue |
| Best efficiency | 22.1 % | their strongest module |
| Power range | 360-455 Wp | smallest to largest |
| Bifacial share | 17 % | 4 dual-sided models |
| Average warranty | 25 years | guaranteed output term |


## 01. The top of the range

The leaders of LG'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 24 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

share of the catalogue


| # | Panel | share | panels |
| --- | --- | --- | --- |
|  | N-type | 100.0% | 24 |

N-type accounts for 100.0% of the catalogue - 24 of 24 modules.


### Efficiency spread

share of the catalogue


| # | Panel | share | panels |
| --- | --- | --- | --- |
|  | \<20% | 16.7% | 4 |
|  | 20-21% | 41.7% | 10 |
|  | 21-22% | 37.5% | 9 |
|  | 22-23% | 4.2% | 1 |


## 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:** Strong warranty coverage averaging 25 years
- **Strength:** Established manufacturer with 68+ years of experience


### Where it is thin

- **Watch out:** Average efficiency of 20.7% is below the industry leading edge
- **Watch out:** Limited bifacial panel options
- **Watch out:** No high-power panels (500W+) available for commercial use
- **Watch out:** Limited adoption of latest cell technologies (TOPCon/HJT)


## 05. In short

> **LG:** LG is a solid option, offering 24 panels suitable for residential installations. With an average efficiency of 20.7% and top models reaching 22.1%, their panels deliver competitive performance.
