A balcony solar kit plugs into a socket and cuts your bill through self-consumption, with no installation work. Here is how to choose the power, whether storage is worth it, and our selection.
How to choose
- Power (Wp): 400 to 800 Wp covers a good share of your base load (standby, fridge, router).
- Built-in micro-inverter: essential to plug safely into a standard socket.
- Storage (optional): a battery stores the day’s surplus for the evening, when you consume most.
- Payback: expect 5 to 8 years depending on sunlight and electricity prices.
