Anyone looking for a photovoltaic provider will sooner or later come across two terms: Swissolar and «Die Solarprofis». The two belong together but do not mean the same thing. Swissolar is the industry association of the Swiss solar sector. «Die Solarprofis» is a quality label of this association for certified specialist companies. This page explains the difference – and shows how to put this information to sensible use when choosing a provider.
Key points at a glance
The key points of this section can be summarised compactly:
- Swissolar is the Swiss industry association for solar energy.
- A Swissolar membership means: a company is part of this industry association.
- “The Solar Pros” is an additional quality label from Swissolar.
- Solar professionals must meet additional acceptance criteria and are assessed according to defined standards.
- For building owners, the label is a strong quality signal but does not replace a quote comparison.
The label can therefore create trust, but it is only one component in choosing a provider. What remains important is how well a specialist installer suits the specific project.

What is Swissolar?
Swissolar is the industry association for solar energy in Switzerland. It represents the interests of the solar industry towards politics and administration, publishes technical information and market data, supports the continuing education and qualification of specialists and advocates for quality in the planning, sale and installation of solar systems.
For building owners, this means: Swissolar is an important source of information and a professional framework for the Swiss solar industry. However, the association is neither a provider of solar systems nor a quote platform. A company can be a Swissolar member without automatically carrying the quality label “Die Solarprofis”.
What are “Die Solarprofis”?
“Die Solarprofis” is a quality label run by Swissolar. It identifies companies that plan, install or sell solar systems in accordance with applicable laws and recognised technical rules. Swissolar describes the label as a guide to certified specialist companies; depending on the focus, this includes evidence of experience, suitability and professional execution.
What is the difference between Swissolar and Solarprofis?
In short: Swissolar is the association, Solarprofis is the audited label level. Swissolar membership shows that a company belongs to the industry association. The Solarprofis label additionally shows that a company meets admission requirements for certain services in the solar sector and is listed in the Solarprofis search.
For choosing a specialist installer, this means: A Swissolar member can be reputable and technically strong, even if it is not listed as a solar pro. A solar pro additionally carries a visible quality label. However, what remains decisive is whether experience, quote, components, consulting and regional support fit your project.
Is a Swissolar label a guarantee?
No. The label is a strong quality signal, but it is not an automatic guarantee of the best offer in your specific case. Even certified specialist installers differ in price, component selection, advice and service. And conversely: not every qualified installer carries the label. A label is therefore a sensible guideline – and one of several.
What else should you pay attention to?
