Is plug-in solar worth it for your home? Plug-in solar panels will be available in the UK soon, letting you generate electricity from your balcony without expensive installation fees or planning permission. Enter your postcode and house or flat number to see how much energy you could generate, and whether it’s likely to be worth it. Start with my postcode How it works We resolve your postcode against Ordnance Survey data, ray-trace the surrounding buildings from Environment Agency LIDAR, then ask PVGIS for an annual yield given the shading we found. We have no database — your address isn't stored. Where do you live? Postcode is required. House number or flat is optional — we use it to pinpoint your building for this calculation, not to store your address. Privacy. Postcode House number or flat Next What floor are you on? Ground floor is 0. Higher floors clear more obstructions but also shift the solar peak season. − 0 Ground + Back Next Which way does your balcony face? Pick the compass direction the panel will point. South is typically best in the UK; east and west still produce well. NW N NE W E SW S SE Back Next About your bill. Roughly how much electricity do you use a year? Pick the closest band — the medium default works for most UK homes. Low 1,800 kWh / year Flat or studio, electric efficient Medium 2,700 kWh / year Typical UK home High 4,100 kWh / year House, electric heating Skip — use the medium default Back Next Your kit and your tariff. UK rules cap plug-in kits at 800 W inverter output, so most kits sold here are around 0.8 kWp — two panels and a microinverter. 0.4 kWp One panel 0.8 kWp Two panels Your electricity tariff Standard variable (EDF / British Gas / similar) Octopus Agile Octopus Cosy Octopus Go Octopus Tracker British Gas standard variable Other fixed rate Advanced. Kit cost and self-consumption Kit cost (£) Install cost (£) £0 assumes a DIY socket install. Until the plug-in safety standard lands (expected mid-2026), the compliant route is a quick hardwire by a registered electrician — add their cost here if that applies. Self-consumption fraction (0 to 1) SEG export rate (p / kWh) Defaults to 0. The Smart Export Guarantee needs an MCS-certified install, which DIY plug-in kits can't get — so most owners earn nothing for exported power, and the value is in what you use yourself. Set a rate only if you have an MCS install. Back Calculate Modelling shading and yield. Something went wrong. Start over Net earner £ kWh Kit cost . incl.

Real yield and savings vary with the weather, your day-to-day electricity use, and how the kit is installed. Where the panel is Show map What the sun sees from your balcony Grey is the sky blocked by nearby buildings (LIDAR-derived). Gold arcs trace the sun on midsummer, the equinox, and midwinter.

Lifetime savings (20 years, net of capex) . Savings come from the power you use yourself: most plug-in kits can't claim the Smart Export Guarantee (it needs an MCS install), so exported energy is assumed to earn nothing. Self-consumption defaults to 60% (spec §3.7). Time-of-use tariffs use a typical-day model. Refresh quarterly. Tell me when kits arrive in the UK. Plug-in solar is in regulatory limbo here — the kits available elsewhere in Europe aren't legally for sale in Britain yet. We're tracking the market.
