# MWG panels, *read off the datasheets*

MW Power is a Polish brand operating under MPL Group, offering a range of technology products including photovoltaic panels sold under the MW Green Power (MWG) brand. Their solar modules are small-wattage units (10W–100W) made from monocrystalline silicon, primarily intended for autonomous...

Everything below is computed from those 2 datasheets: no score out of ten, no ranking of brands against each other, and nothing a manufacturer can pay to change. Where MWG does not publish a figure, it is left out of the average rather than assumed.


## The company

- **Founded:** 2005
- **Headquarters:** Zabrze, Poland

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 | 2 | models in the database |
| Average efficiency | 19.7 % | across the catalogue |
| Best efficiency | 20.1 % | their strongest module |
| Power range | 340-400 Wp | smallest to largest |
| Bifacial share | 0 % | 0 dual-sided models |
| Average warranty | 25 years | guaranteed output term |


## 01. The top of the range

The leaders of MWG'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 | [MWG-340M](https://comparepv.com/panel/mwg-mwg-340m) | 340 Wp | 20.1% |
| 2 | [MWG-400M](https://comparepv.com/panel/mwg-mwg-400m) | 400 Wp | 19.3% |

- MWG-340M - Monocrystalline
- MWG-400M - Monocrystalline

### Highest power

nameplate output


| # | Panel | efficiency | power |
| --- | --- | --- | --- |
| 1 | [MWG-400M](https://comparepv.com/panel/mwg-mwg-400m) | 19.3% | 400 Wp |
| 2 | [MWG-340M](https://comparepv.com/panel/mwg-mwg-340m) | 20.1% | 340 Wp |

- MWG-400M - Monocrystalline
- MWG-340M - Monocrystalline

## 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.


### For a house roof

380-460 Wp


| # | Panel | power | efficiency |
| --- | --- | --- | --- |
| 1 | [MWG-400M](https://comparepv.com/panel/mwg-mwg-400m) | 400 Wp | 19.3% |

- MWG-400M - Monocrystalline


## 03. What the catalogue is made of

Shares are of the 2 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 |
| --- | --- | --- | --- |
|  | Unknown | 100.0% | 2 |

Unknown accounts for 100.0% of the catalogue - 2 of 2 modules.


### Efficiency spread

share of the catalogue


| # | Panel | share | panels |
| --- | --- | --- | --- |
|  | \<20% | 50.0% | 1 |
|  | 20-21% | 50.0% | 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 21+ years of experience


### Where it is thin

- **Watch out:** Average efficiency of 19.7% 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

> **MWG:** MWG is a solid option, offering 2 panels suitable for residential installations. With an average efficiency of 19.7% and top models reaching 20.1%, their panels deliver competitive performance.
