29.7 kWp Zero Feed-In photovoltaic system with 48 kWh of batteries, luxury villa complex, Blefouti, Leros
A 29.7 kWp photovoltaic system for a complex of luxury villas in Blefouti, Leros, operating as self-consumption with Zero Feed-In. The installation consists of three 10 kW systems, each with a 10 kW SMA hybrid inverter and a 16 kWh BYD battery, with 54 AE Solar 550 W panels and 48 kWh of storage in total. Estimated production is 44,100 kWh a year (14,700 kWh per system), with self-sufficiency of up to 85%. Design, installation and grid connection by Helios Dynamics, 2026.

- Solar panels
The challenge
Luxury villas have high consumption in the season, from air conditioning and pools, and much of it falls in the evening, when there is no production. The goal was to cover as much of it as possible from the sun, without exporting to the grid.
The solution
Three 10 kW systems, each with an SMA hybrid inverter and a 16 kWh BYD battery. The batteries store the daytime surplus for the evening, for self-sufficiency of up to 85%.
