Plug-in Solar Starter Kit Checklist: Everything You Need
The complete shopping list for your first plug-in solar installation. Panels, monitoring, tools, and accessories — nothing forgotten.
Before You Start
Getting your first plug-in solar system installed is simpler than most people expect. But there's a difference between "panels on a wall" and "a properly monitored, weatherproofed system that'll last 20 years." This checklist covers everything — the essentials and the small things that make the difference.
The Core System
Plug-in solar kit. The EcoFlow STREAM is the government-backed option — 800W micro inverter with two 400W panels, Wi-Fi monitoring, and UK plug. It's the simplest path from box to generating.

If you're buying components separately, you'll need panels (400–800W total), a grid-tied micro inverter (must be anti-islanding compliant for UK use), and MC4 cables to connect them.
Monitoring
A smart plug between your inverter and the wall socket is the single most useful addition. It tells you exactly how much you're generating, spots problems early, and makes your savings tangible.
Budget option: TP-Link Tapo P110 (~£12). Does everything you need — real-time watts, daily/monthly tracking, cost calculation.
Smart home option: Shelly Plus Plug (~£15). Works locally without cloud dependency. Perfect if you run Home Assistant.

Whole-home option: Emporia Vue 3 (~£130). Clamps around your main supply cables and shows total home consumption alongside solar generation. Eye-opening data.

Tools
For a standard balcony or wall installation, you need surprisingly little. A spirit level, a pencil, and the fixings that come with your kit. That's genuinely it for most installs.
For troubleshooting, a multimeter is essential. The Fluke 117 is the professional standard — true RMS, clear display, built to last decades. Worth the investment if you're serious about DIY solar.

Cable Management
Loose cables degrade in UV, create trip hazards, and look terrible. Sort this on day one.
UV-resistant cable ties are the minimum — standard nylon ties go brittle in sunlight within a year. UV-stabilised ties last 5+ years and cost pennies more.

MC4 extension cables if your panels are more than a couple of metres from the inverter. Buy the same brand as your panel connectors for compatibility.

Weatherproofing
IP68 cable glands for any junction boxes or enclosures. They seal around your cables and keep water out — essential for outdoor electrical connections.

Optional But Recommended
Adjustable tilt mount if your panels aren't on an ideally angled surface. Even 10 degrees of tilt adjustment can boost annual output by 15–20%.

Bird proofing mesh if you're roof-mounting. Pigeons love nesting under solar panels — mesh prevents this before it becomes a problem.

Portable power station to store daytime solar for evening use. See our battery comparison guide for recommendations.
The Shopping Summary
The bare minimum for a working system: plug-in solar kit + smart plug = ~£960. Add cable management and weatherproofing for another £30–50. Add a battery for £600–1,000 if you want evening coverage.
Total for a fully kitted-out system with monitoring, storage, and proper installation: roughly £1,600–2,000. That's still less than half the cost of a traditional rooftop solar installation, and you can take it with you when you move.
