About SunHestia
SunHestia builds residential solar photovoltaic and battery storage systems. Our focus is self-consumption: helping homeowners generate clean electricity, store it, and use it themselves.
What we believe
Rooftop solar is most valuable when the energy it produces is used in the home it came from. Selling surplus back to the grid at a low rate and buying power back at a high rate rarely serves the homeowner. Storage changes that equation: it lets a household keep its own clean energy and spend it after the sun goes down.
SunHestia exists to make that straightforward — pairing reliable generation with right-sized storage, designed for the homes and climates of Europe.
How we work
Self-sufficiency first
We design for high self-consumption, so homeowners rely less on the grid and more on their own roof.
Right-sized, not oversized
A system should match the home and its use — not the biggest stack of hardware we can sell.
Clean by default
Emission-free electricity, long-lived hardware, and chemistries without cobalt.
Local rules respected
Every system is configured to the connection rules and tariffs of its country.
Who we build for
Our systems are designed for owner-occupiers of detached houses: people who control their own roof, plan to stay in their home for years, and want to reduce their dependence on grid electricity. If that sounds like you, we would be glad to design a system for your home.
