Who Designs and Installs Your SunHestia System
SunHestia designs residential solar photovoltaic and battery storage systems for European homeowners, with one focus above all others: self-consumption — the share of the electricity your solar panels produce that you use in your own home rather than exporting to the grid. Storage shifts surplus to when it is needed, sharply increasing self-consumption, and it is the single number that most influences the value of a residential solar system. Every design decision described below is made to raise that number, and every system is configured to the connection rules and tariffs of your country.
How your system is designed
- Consumption first, not a template. Battery size is matched to your evening electricity use. A common starting point for a detached home is 5–10 kWh, stackable to around 15 kWh — sized from your actual consumption, never a one-size-fits-all figure.
- Roof-by-roof assessment. Each roof is assessed individually: pitched tile and metal roofs, flat roofs on garages, and ground-mounted frames where the main roof is shaded. Orientation and shading both affect yield.
- Built for owner-occupiers. Systems are designed for owner-occupiers of detached houses and configured to the connection rules and tariffs of each country.

Hybrid Inverter & Energy Manager
- Converts solar DC power for the home and routes power between panels, battery, home and grid — drawing from the grid only when needed
- Real-time app monitoring of production, storage and consumption
- Backup-capable for short outages
- Supports time-of-use scheduling
Installation: often a single day on site
For a typical detached home, the physical installation is often completed within a day once the system is designed and the hardware is on site. The design work — sizing, roof assessment and configuration to your country's rules — happens before anyone climbs a ladder.
The guarantees behind the work
| Component | Guarantee |
|---|---|
| SunHestia Solar PV Modules | 25-year linear performance guarantee |
| SunHestia Home Battery | 10-year warranty |
Frequently asked questions
What does a residential solar and storage system include?
Typically rooftop solar panels, a hybrid inverter, and a home battery. The panels produce electricity, the inverter routes it to your home or the battery, and the battery stores surplus for use after dark.
Do I need a battery with solar panels?
Solar works without a battery, but without storage most daytime surplus is exported to the grid. A battery lets you keep and use that energy yourself, which is usually better value than selling low and buying back high.
How long does installation take?
For a typical detached home, the physical installation is often completed within a day once the system is designed and the hardware is on site.
What warranty do you offer?
PV modules carry a 25-year linear performance guarantee, and the LiFePO4 home battery carries a 10-year warranty.
