Compare plug-in solar kits by output, mounting options, UK support and practical value for flats, renters and homes without a full rooftop solar installation.
EcoFlow STREAM Balcony Solar System
Best overallBest for: most households that want a polished, app-connected plug-in solar kit from a major portable power brand.
EcoFlow takes our top overall spot because it combines a recognisable brand, a complete 800W microinverter package, two 400W solar panels, Wi-Fi and app control, and flexible mounting options for balconies, gardens, roofs and vertical walls.
The STREAM system is designed to convert daytime solar generation into ready-to-use home electricity, helping cover regular background loads such as Wi-Fi routers, fridges, TVs and small appliances. EcoFlow says the system can generate up to 858 kWh per year and help reduce electricity costs by up to £115 annually, depending on location, setup and how much solar power you use at home.
It is the best all-round pick because it feels closest to a consumer-ready product: clear UK-facing product information, app monitoring, strong brand support, and a setup that should suit more homes than balcony-only kits.

How we test and rank kits
Every rated kit is bought by SunToSocket and tested in real UK home conditions. We look at setup, mounting, app experience, generation, safety documentation, support and overall value before deciding where a kit ranks.
No manufacturer, retailer or supplier has editorial control over our ratings, rankings or what we publish. Companies do not get to approve, edit or influence our conclusions.
