# KIOTO Solar panels, *read off the datasheets*

KIOTO Solar (KIOTO Photovoltaics GmbH) is an Austrian manufacturer of photovoltaic modules, producing panels exclusively at its facility in St. Veit an der Glan, Carinthia. The company traces its roots to 1991 as part of the Sonnenkraft group, with PV module production...

Everything below is computed from those 7 datasheets: no score out of ten, no ranking of brands against each other, and nothing a manufacturer can pay to change. Where KIOTO Solar does not publish a figure, it is left out of the average rather than assumed.


## The company

- **Founded:** 1991
- **Headquarters:** St. Veit an der Glan, Austria
- **Annual capacity:** \<1 GW
- **Employees:** 201-500

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 | 7 | models in the database |
| Average efficiency | 22.5 % | across the catalogue |
| Best efficiency | 22.8 % | their strongest module |
| Power range | 440-450 Wp | smallest to largest |
| Bifacial share | 57 % | 4 dual-sided models |
| Average warranty | 27 years | guaranteed output term |


## 01. The top of the range

The leaders of KIOTO 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 7 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 | 100.0% | 7 |

TOPCon accounts for 100.0% of the catalogue - 7 of 7 modules.


### Efficiency spread

| # | Panel | share | panels |
| --- | --- | --- | --- |
|  | 22-23% | 100.0% | 7 |


## 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:** High-efficiency panels available (up to 22.8%)
- **Strength:** Strong bifacial lineup - 57% of portfolio supports dual-sided generation
- **Strength:** Strong warranty coverage averaging 27 years
- **Strength:** Established manufacturer with 35+ years of experience
- **Strength:** Large-scale production capacity of \<1 GW


### Where it is thin

- **Watch out:** No high-power panels (500W+) available for commercial use


## 05. In short

> **KIOTO Solar:** KIOTO Solar is a solid option, offering 7 panels suitable for residential installations. With an average efficiency of 22.5% and top models reaching 22.8%, their panels deliver competitive performance.
