Battery retrofit in Edinburgh
Can I retrofit a battery to my solar panels in Edinburgh?
Quick answer: Yes, we install batteries in Edinburgh. Edinburgh is in the SP Energy Networks DNO area. Conservation area and listed building constraints may apply. Most pre-2018 solar systems in Edinburgh use string inverters, meaning AC-coupling or a hybrid swap is the likely path. A no-obligation survey confirms your exact compatibility and price.
Edinburgh is in the SP Energy Networks DNO area and has the highest concentration of conservation areas and listed buildings of any Scottish city. This affects solar panel permissions and, by extension, where a battery can be sited. This guide covers DNO rules, conservation constraints, housing types and local solar yield ranges.
DNO: SP Energy Networks
Edinburgh postcodes are served by SP Energy Networks. Batteries over 3.68kW per phase require G99 prior approval — typically 4 to 8 weeks. Smaller systems use G98 notification within 28 days of install. We handle all DNO paperwork as part of the process.
Conservation areas and listed buildings
Edinburgh has extensive conservation areas, particularly in the New Town, Old Town, Marchmont, Morningside and Stockbridge. If your property is listed or in a conservation area, solar panel installation may have required planning permission or listed building consent. Battery retrofits to existing solar systems typically do not require additional planning permission because the battery is installed internally or in a garage — but you should confirm this during the survey.
Housing types and battery siting
Edinburgh tenements in Marchmont, Bruntsfield and Leith present similar co-owner consent challenges to Glasgow tenements. Stone-built villas and bungalows in areas like Barnton, Cramond and Liberton usually have loft or garage space suitable for a battery. Newer developments in South Gyle and Granton typically have modern wiring that simplifies the retrofit.
Typical system sizes and yields
Existing solar systems in Edinburgh range from 2kWp on tenement roofs to 4kWp on detached homes. A typical 4kWp system in Edinburgh generates roughly 2,700 to 3,100 kWh per year, per MCS MIS 3002 — slightly lower than Glasgow due to a marginally less favourable latitude. These are ranges — a no-obligation survey provides exact figures.
Weather and generation patterns
Edinburgh sits on the drier east coast, which means it generally receives more sunshine hours than Glasgow, though generation is still modest in winter months. The Firth of Forth can create localised fog and haar in spring and early summer, temporarily reducing generation on some days. A battery helps smooth these daily variations by storing excess generation for use when the panels are not producing. Easterly winds can also affect panel efficiency if your roof is exposed. The no-obligation survey accounts for local weather patterns and your specific roof orientation when modelling expected generation. As a guide, Edinburgh systems tend to produce slightly less than Glasgow systems at the same system size, though the difference is modest and individual roof conditions matter more than the city-level average.
Three-phase supply in Edinburgh
Some larger properties in Edinburgh — particularly Victorian villas in areas like Barnton, Cramond and the Grange, and some commercial buildings — have three-phase electricity supply rather than single-phase. Three-phase supply affects the G99 threshold calculation because the 3.68kW limit applies per phase, meaning a three-phase connection can accommodate a larger battery without prior approval. However, three-phase battery installations require a compatible three-phase inverter, which narrows the equipment options. The surveyor will confirm whether your property has single-phase or three-phase supply and advise on the appropriate battery configuration. Most Edinburgh homes are single-phase, so this is only relevant for a minority of properties.
Frequently asked questions
Do you install batteries in Edinburgh?
Yes. We serve all Edinburgh postcodes. Edinburgh is in the SP Energy Networks DNO area. Batteries over 3.68kW require G99 prior approval; smaller systems use G98 notification. We handle all DNO paperwork.
Can I add a battery to my existing solar in Edinburgh?
Yes — if you have a string inverter installed before 2018, AC-coupling (Tesla Powerwall 3) or a hybrid swap is likely. If you already have a hybrid inverter, a Pylontech US5000 add-on may be possible. Run the compatibility checker to confirm.
