Balcony Solar Calculator (Balkonkraftwerk)

Living in an apartment? Calculate exactly how much money a plug-in solar panel will save you. Adjust for vertical mounting, standby consumption, and EU power limits (400W–800W).

150W
Fridges, routers, and standby electronics. Usually ~150W for an apartment. Higher base load = less wasted exported energy.

Did you know? In Germany, standard plug-in balconies (Balkonkraftwerke) are limited to 800W inverter output as of 2024.

Total Generated:800 kWh
Self-Consumed (Usable):430 kWh
Exported to Grid (Lost):370 kWh

*Self-consumption is estimated based on your apartment's standby power (base load). Since you generally aren't paid for feeding power back into the grid with a plug-in system, maximizing self-consumption is key to ROI.
