I want to save money right now with no installation
Anker SOLIX C1000 — fully legal, no electrician, powers appliances directly from battery charged by solar. Off-grid use only.
I want the best all-round balcony solar system
EcoFlow STREAM Balcony System — named UK government partner, 10-year warranty, excellent app. Standalone inverter from ~£129 or full bundle from ~£449.
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 want the lowest cost entry point
EcoFlow STREAM Microinverter (standalone) — from ~£129, add your own compatible panels for a total system cost of ~£250–£450.
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
Anker SOLIX C1000 for immediate use. For balcony solar, wait for July 2026 BSI standard when self-installation becomes legal — making it far more practical for renters.
