How to Choose

I want the lowest upfront cost

Watch for the supermarket complete kit expected once the BSI standard is confirmed (anticipated July 2026), which is likely to be the most affordable option. Until then the EcoFlow STREAM Balcony System is the cheapest complete kit we list.

I want the best all-round balcony solar system

EcoFlow STREAM Balcony System — named UK government partner, complete kit (2x450W panels + 800W inverter) from £449, 5-year inverter warranty, excellent app.

I want solar energy in the evenings too

EcoFlow STREAM Ultra — 1.92 kWh LFP battery built in, expandable to 11.52 kWh. Battery storage pushes self-consumption from ~35% to ~70–80%.

I work from home or have high daytime electricity use

Any grid-connected system works well for you — your self-consumption rate will be high, which dramatically improves the payback period.

I am a renter or flat dweller

Wait for the July 2026 BSI standard, when certified kits can be self-installed without an electrician — making complete kits far more practical for renters. Always check your tenancy agreement and get landlord permission first.

Prices approximate and subject to change. All grid-connected systems require electrician installation until BSI product standard confirmed (expected July 2026). See our UK legal guide for full details.
