05 · THE OFFICE
About
A solar company on the avenue, not a call centre
Geosolar works from an office on Avenida Tenente-Coronel Silva Simões, in Viseu, open every weekday from 9 to 7. It supplies the equipment, installs it and handles the paperwork, so you deal with one company from the study to the connection.
Clients point to two things: good advice and fast processing. That includes clients who live here but speak German first.

07 · QUESTIONS
Questions
Before the visit
It depends on how much you use and when. A well-sized self-consumption system usually covers 30 to 60% of a home's bill. The technical visit gives your number.
Home systems up to 30 kW are registered with the DGEG by prior notice. We handle the registration and the E-Redes side.
Usually one or two days on site for a home. The licensing can take a few weeks.
Not always. They pay off when most of your consumption is at night, and they can be added later.
Cleaning now and then and a check of the inverter. Production is followed on an app, so a drop shows up quickly.
Yes, across the Viseu region. Call and tell us where you are.
