Tesla Energy Certified Installer
The world leader in energy storage certified us.
STILCA Energy is a Tesla Energy Certified Installer. We design, install and service Tesla Powerwall storage with thirty years of energy expertise behind us. For you it means one thing: quality verified against the industry's highest standard.
Not a reseller. A certified installer.
Becoming a Tesla Energy Certified Installer can't be bought — it's earned. Tesla selects its partners, trains the technicians and verifies design, installation and service standards. It's the recognition that the world leader in storage entrusts its product only to those who know how to handle it.
For you, the customer, the certification is a concrete guarantee: the system is designed to Tesla's rules, installed by trained technicians and serviced over time through the official network. No improvisation, no weak link between you and the technology.
Standards verified by Tesla
Design and installation follow the manufacturer's official protocols, not improvised practice.
Trained, up-to-date technicians
Continuous Tesla training on product, safety and storage commissioning.
Part of the official network
Service, spare parts and updates through direct Tesla Energy channels.
What changes for you.
A storage system lasts twenty years. The difference between a great system and a costly problem is who designs it, who installs it and who's there when it matters.
Guaranteed continuity
Backup engineered properly: when the grid goes down, your home or business stays powered.
Full, valid warranty
Certified installation keeps the Tesla storage warranty intact and fully honoured.
Certified safety
Compliance with Italian standards (CEI 0-21) and Tesla safety requirements, verified at commissioning.
Monitoring and control
Manage energy from the Tesla app: consumption, production and autonomy under control, anywhere.
Long-term service
A single point of contact for design, installation, commissioning and maintenance. Even ten years from now.
More value from energy
Maximised self-consumption and lower bills: the energy you produce is used when it really counts.
Thirty years in energy. Storage at the centre.
STILCA Energy grew out of its founder's experience in industrial automation and industrial-scale solar. Over the years, plants totalling several megawatts have been developed and managed.
Added to that is a unique track record in the service and repair of solar inverters, built through STI Repair, active since 1997. The Tesla certification doesn't land on a blank page: it rewards expertise that was already there.
It's the same principle behind every Tesla storage system we sign off: not selling a battery, but engineering a system that keeps delivering year after year.
