Mon Parcours Solaire: a platform dedicated to photovoltaic projects

Publié le 04 novembre 2026 - Public Service / (Prime Minister)

Do you want to reduce your electricity bill and produce your own photovoltaic electricity? The association Hespul, with the support of ADEME and DGEC, has created a free digital tool to accompany you in your steps: My Solar Journey. Public Service inform you.

My Solar Journey, created by the Hespul Association, is a platform that supports you in your equipment project. Its mission is to provide you with a simulation of your residential solar photovoltaic project by evaluating the solar potential of your roof and comparing for you the self-consumption and valorization solutions of your future production. It is a neutral and independent digital tool.

Why install of photovoltaic panels on your roof?

Residential photovoltaics can reduce your electricity bill by shifting your consumption to solar production hours. This way, you participate at your own level in the energy transition.

Test the My Solar Journey simulator and have the photovoltaic potential of your roof evaluated. This estimate is as close as possible to reality to allow you to position yourself vis-à-vis the interest of a project and the commercial offers that can be proposed to you. However, each case is unique and this online tool can never replace a more extensive technical study. Do not hesitate to contact My Solar Path via this form.

What is photovoltaic?

Photovoltaics refers to the technology and physical process that transforms sunlight into electricity. This electricity produced by the panels placed on the roof or on the ground can be consumed immediately by the fireplace (household appliances, heating, hot water...) or injected into the electrical network.

You can choose, as a producer, to sell all the electricity, the surplus or to be self-consumption without sale. If you choose to sell the surplus or all of the electricity produced, it can be injected into the public grid.
