Greek-rule review
Maximum values require high output, good exposure, and high self-consumption. They are not guaranteed returns.
The pages that matter now
One hub, four decision pages, and one calculator. Every page uses the same prices, assumptions, and sources.

Rules first, equipment order second
We do not promise a final manufacturer or final balcony-specific process before equipment and official requirements are locked.
The rules page separates confirmed facts, pending decisions, and Sunrail interpretation.
Athens installation for €99. The first review checks balcony photo, shade, space, mounting, cable route, and suitability before final equipment order.
Reserve your Sunrail system
We review the balcony, estimate payback, and confirm the compliant setup before equipment is ordered.
- Reservation is refundable if the balcony is not suitable.
- Final price and equipment are confirmed before ordering.
- We do not name a final manufacturer before supply is locked.
Add a photo for review The first review is manual, not an automatic promise to install.
Questions, answered
We proceed only when the final installation matches the official process and technical requirements.
No. Sunrail is designed for apartment balconies and terraces.
Not always. A battery is more useful when you are away during the day or use more power in the evening.
