We are not just another installer. We are engineers.
It makes no sense to own an electric car and an installation that is not up to it. Solventium Ingenieros S.L. is an engineering firm devoted exclusively to electric mobility, based in Las Rozas de Madrid with more than 2,500 installations completed in homes, shared garages and fleets, all certified and registered with the authorities.
We know how electricity, chargers and batteries work, and that is why we approach every installation with an engineer's judgement. Our aim is to electrify the vehicle fleet in the safest, most professional and most sensible way possible, because this is the mobility of the future and the only way to do it is well.
We see what others miss.
First we listen
We design the installation around you: what car you drive, how you charge and what you will need five years from now.
Everything clear from the start
A detailed proposal before we execute. If the survey uncovers something unexpected, we talk to you before touching a single cable.
Payment on completion
Payment is due once the charger is up and running, unless your contract agrees a different form of payment.
Engineering criteria
We recommend the charger that best fits your car and your installation, not whatever is in stock.
First-rate materials
Toscano protections, cabling and conduit sized for the real power, fitted to code and checked point by point.
Fully compliant
Authorised installation company. Certificate, registration with the authorities and grants processed. You file no paperwork.
One point of responsibility, authorised installers
We work with authorised partner installers in Madrid, and Solventium answers to you for the installation, with a 10-year warranty on the installation work. Since September 2026, installations are handed over with a checklist and an end-of-job report with photos. After-sales is handled by our after-sales team in Madrid.
Support afterwards
Electricity tariff, solar panels, car settings to look after the battery: you have our advice throughout your new electric life.
We start whenever you like.
Tell us where your parking space is and what car you have. We will prepare a detailed, no-obligation proposal.
