# Growatt panels, *read off the datasheets*

Growatt has 1 modules in the database, from 150 to 150 Wp.

Everything below is computed from those 1 datasheets: no score out of ten, no ranking of brands against each other, and nothing a manufacturer can pay to change. Where Growatt does not publish a figure, it is left out of the average rather than assumed.


## The company

- **Founded:** 2010
- **Headquarters:** Shenzhen, China

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 | 1 | models in the database |
| Average efficiency | 18.6 % | across the catalogue |
| Best efficiency | 18.6 % | their strongest module |
| Power range | 150-150 Wp | smallest to largest |
| Bifacial share | 0 % | 0 dual-sided models |
| Average warranty | - years | guaranteed output term |


## 01. The top of the range

The leaders of Growatt'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.


### Most efficient

module efficiency


| # | Panel | power | efficiency |
| --- | --- | --- | --- |
| 1 | [TS-EFS150M](https://comparepv.com/panel/growatt-ts-efs150m) | 150 Wp | 18.6% |

- TS-EFS150M - Monocrystalline

### Highest power

| # | Panel | efficiency | power |
| --- | --- | --- | --- |
| 1 | [TS-EFS150M](https://comparepv.com/panel/growatt-ts-efs150m) | 18.6% | 150 Wp |

## 02. What the catalogue is made of

Shares are of the 1 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 |
| --- | --- | --- | --- |
|  | PERC | 100.0% | 1 |

PERC accounts for 100.0% of the catalogue - 1 of 1 modules.


### Efficiency spread

| # | Panel | share | panels |
| --- | --- | --- | --- |
|  | \<20% | 100.0% | 1 |


## 03. 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.


### Where it is thin

- **Watch out:** Average efficiency of 18.6% 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)


## 04. In short

> **Growatt:** Growatt is a solid option, offering 1 panels suitable for residential installations. With an average efficiency of 18.6% and top models reaching 18.6%, their panels deliver competitive performance.
