What is a balcony solar kit?
A balcony solar kit is a small solar power system you install yourself. Solar panels on a balcony, wall, terrace or roof feed a microinverter, which turns their power into normal household electricity. You plug the cable into a socket, and your home uses that electricity first, before it buys any from the grid. Every Robinsun kit comes complete: panels, microinverter, mount and cable.
How much power is allowed in your country?
Most European countries allow kits with up to 800 W of inverter output to be installed by the owner, and in April 2026 the European Commission recommended that limit to all member states. How many panels you may connect, and whether you have to register the kit, still differ from country to country. Our plug-in solar rules by country list the limits, the registration steps and the official sources for each market.
Kits above 800 W, such as our 2000 W kits, are treated as regular solar systems in most countries and may need an installer or a grid connection request. Check your country page before you order one.
How to choose your kit
- Power. One panel (500 W kits) suits a small balcony and low daytime use. Two panels with an 800 W microinverter (800 W kits) are the most popular choice. Four panels (2000 W kits) suit houses with a garden or roof and higher consumption.
- Panels. Performance kits use Aiko panels with ABC cells, among the most efficient on the market. Eco kits use Tier 1 panels at a lower price.
- Mount. Pick the version for where the panels go: balcony railing, wall, flat roof or garden, tile roof or metal roof. The Performance 800 Basic comes without a mount, for your own structure.
- Battery. If you are out during the day, a battery stores the surplus for the evening. See our balcony solar kits with battery.
What a kit saves
A two-panel 800 W kit produces up to 1,600 kWh a year in southern Europe, and less further north. How much you save depends on how much of that electricity you use yourself and on what you pay per kWh. Our savings calculator estimates production and savings for your location, panel angle and orientation.
Installed in minutes
If you can assemble simple furniture and plug in an appliance, you can install a Robinsun kit. Every kit ships with step-by-step instructions, and our installation videos show each mount type. The microinverter connects to an app, so you can follow your production in real time.
