KATHENERA solar kit installed on a Greek apartment balcony

Balcony & compact home solar

Solar for balconies and smaller homes, planned for your space.

Explore possible kit configurations using your available space, orientation, shade and electricity use. Mounting and connection requirements need a site-specific check.

What to check first

Start with space, installation and electricity use.

What to check first

  1. 01

    How much balcony space is usable?

    Dimensions, orientation, shade and fixing surfaces affect which modules and mounting methods are possible.

  2. 02

    Can you install in an apartment or rental?

    Check ownership or lease terms, building rules, fixing method and applicable electrical connection requirements first.

  3. 03

    Would storage be useful?

    Daytime surplus and evening use determine whether storage is worth assessing; compatibility and placement also matter.

What to check at the balcony

Start with orientation, shade, fixing surfaces and the electrical connection. The equipment and installation plan depend on your balcony.

Share approximate measurements and photos only when requested. Fixing and electrical connection need a qualified site check.

Understand the estimate

Illustrative estimate; site conditions and a complete quote are needed for a purchase decision.

Mounting

Same 800 W example for both; savings follow your battery and electricity-price choices.

Annual savings

€245/ year
Annual production
1,200 kWh / year
Self-consumption

Example assumptions: 800 W, Attica sunlight, 55% self-use without storage or 85% with storage. Enter a complete installed cost to estimate simple payback. This excludes maintenance, degradation and financing; it is not a quote or forecast for your site.

  • The calculator uses example sunlight, self-use rates and your tariff; it is not a generation forecast for your property.
  • Check site-specific connection, safety and building requirements before buying.
  • Ask for confirmed dimensions, configuration, price and lead time before choosing a kit.

Possible system components

Combine kits, storage and controls around your needs.

Explore balcony solar first, then assess storage, generation controls or home charging against evening use, connection conditions and existing equipment. Check compatibility for every combination.

Home storage

Store some daytime generation for evening use; capacity and compatibility depend on actual demand and equipment.

Zero-export control

Export limiting must suit the equipment and connection requirements; it does not remove applicable procedures.

Home EV charging

If you plan home EV charging, check electrical capacity, installation conditions and how it works with other equipment.

What matters

A balcony or terrace may offer space for solar. Share dimensions, shading and electricity use so we can discuss a suitable direction.

01

System sizing

Suitable power depends on your space, equipment and applicable connection requirements; confirm these before purchase.

02

Zero feed-in

Zero-export controls can limit electricity sent to the grid, but do not automatically remove registration, connection or building requirements.

03

Connection requirements

Registration, connection and building requirements must be checked for the specific site and equipment with a qualified professional and the relevant authorities.

04

Optional storage

Battery suitability depends on daytime surplus, evening use and the selected equipment.

05

Anti-islanding protection

Applicable protection and outage behaviour must be checked for the exact equipment and local connection requirements.

06

Equipment documentation

Confirm model-specific safety and conformity documentation before ordering.

Frequently asked questions

Do I need a permit?
Registration, connection and building requirements must be checked for the specific site and equipment with a qualified professional and the relevant authorities.
Can I install more than 800 W?
Suitable power depends on your space, equipment and applicable connection requirements; confirm these before purchase.
Do I have power during an outage?
Backup power requires suitable battery and inverter outputs and a verified installation design. A battery alone does not guarantee power during an outage.
I rent, or live in an apartment building — can I install?
Possibly, but check lease or building rules, the façade and fixing conditions, and applicable electrical requirements. A removable design does not replace these checks.
How fast does it pay back?
Payback depends on generation, shading, self-consumption, tariffs and the full installed cost. A site-specific estimate is needed; no fixed payback period is promised.

Registration, connection and building requirements must be checked for the specific site and equipment with a qualified professional and the relevant authorities.

Project enquiry

See whether balcony solar suits your site.

Tell us the property type, city and what you want the system to achieve. Photos and detailed measurements can follow only if they are useful. A consultation request is non-binding. Product availability and installation are checked before any order is confirmed.
