Bills are high, but the next step feels unclear
Advice online conflicts. We explain power limits, self-use rules, and realistic results — then help you choose the right kit.
Balcony & home kits
Solar you can use at home — simple, compliant, and built to cut bills.
Electricity costs keep rising, and not every home has a private roof. KATHENERA kits are designed for balconies, terraces, and smaller homes: matched components, self-consumption, optional storage, with registration and install support from our team.
Made for you if
You want lower bills without the stress.
02
You rent or live in an apartment without a roof
Install on a balcony railing or terrace: self-consumption, battery-ready, and fully removable when you move.
03
You worry about paperwork and compliance
The new framework is mainly DEDDIE registration, not a long grid-connection licence. We help prepare the documents with you.
How you can start
Start with a kit. Add an Energy Space later if you need a full place to stay.
Most households begin with a balcony or home kit — power first, numbers clear. If you later need a stay-ready retreat or hospitality unit, we plan the Energy Space with solar and storage as one project.
New framework · up to 800 W
What matters
We asked many Athens homeowners the same simple question: with electricity this expensive, would you install a balcony solar kit? Almost everyone said yes without hesitation. That's why we built this.
01
Up to 800 W output
Maximum grid-injection capacity of 800 W and installed capacity up to 900 W — the same limit used in Germany and Austria.
02
Zero feed-in
The energy covers exclusively your own needs. No electricity is exported to the grid.
03
Registration, not licensing
A declaration on the DEDDIE platform with wattage, model and type — instead of the multi-year approval process of rooftop PV.
04
Batteries allowed
Standalone storage systems are permitted — the key to real savings after sunset.
05
Anti-islanding protection
Mandatory automatic disconnection during outages, protecting the grid and repair crews.
06
Certified equipment
Penalties apply for false declarations. All our kits comply with the power limits and safety standards.

Frequently asked questions
- Do I need a permit?
- Not the licensing process of larger PV systems. The new framework requires a simple registration on the DEDDIE platform with wattage, model and type — we handle it for you. Final details are set by the ministerial decision.
- Can I install more than 800 W?
- No. The limit is 800 W grid output and 900 W installed capacity, with penalties for false declarations. The legal way to get more energy is adding a battery — or upgrading to a full rooftop system.
- Do I have power during an outage?
- The PV side disconnects automatically during outages (anti-islanding, protecting repair crews). Kits with a battery can power essential devices from the battery's independent output.
- I rent, or live in an apartment building — can I install?
- The mounts clamp onto the railing without drilling, and the whole system moves with you. For building façades, it's wise to check with your landlord or building management first.
- How fast does it pay back?
- With Athens sunshine and ~€0.24/kWh: about 3 years without a battery, 4–5 years with one — on a system that lasts over 10 years. Use the calculator above with your own numbers.
