Understanding the profile
Photosun presents itself as a renewable energy consulting and research company, specializing in the installation of photovoltaic panels and heat pumps in French-speaking Switzerland. The profile is particularly relevant for a Valais owner who is considering an energy renovation combining electricity production and heating.
In alpine terrain, a serious comparison must include more than the number of panels. Snow load, access, scaffolding, roof condition, fixing, cable runs and inverter location may change price and schedule. If photovoltaics and heat pump are studied together, future consumption must be added to the sizing, without assuming that a battery will automatically be profitable.

For which projects is this profile relevant?
Houses in Valais and French-speaking Switzerland who wish to compare a photovoltaic project, with particular attention to the roof, local conditions and a possible heat pump.
Prepare the project well
Before the study, research the year of construction, the last roofing interventions and the static documents available. Photograph access points and areas where scaffolding could be installed. For the heat pump, indicate the current heating consumption, flow temperatures and existing radiators. Photosun will then be able to separate thermal needs from solar potential and avoid a comparison based on global promises.
How to compare the offer
Separate modules, inverter, fixing, scaffolding, roof and electricity in the quote. This reading prevents a roof repair or access difficulty from being discovered after signature.
Ask for estimated monthly production, not just annual. For a heat pump, add its expected consumption and check that the electrical connection and available power are sufficient.
Questions to ask before signing
- 1What hypothesis of snow and wind guides the binding?
- 2Does the roof need work before installation?
- 3Who carries out and guarantees the electrical work?
- 4What monitoring and maintenance are offered?
- 5How does the heat pump modify the solar sizing?
Frequently asked questions
Does Photosun also offer heat pumps?
Yes. This specialty is published on the official presentation of the company.
Why examine the roof separately?
Waterproofing, fixing, snow and access influence the safety, price and guarantees of a solar project.
Is Solar Panel Swiss a partner of Photosun?
No partnership is presumed. This sheet is editorial and the official website remains the source of direct contact.
