SolaX Triple Power for a small terrace in Edinburgh
Updated
A small terrace in Edinburgh needs a cupboard that meets the SolaX Triple Power datasheet. Do not import a detached-house cabinet into Edinburgh just because the brand is familiar.
SolaX Triple Power on a small terrace in Edinburgh
The New Town will argue about the stone. The suburbs will argue about the tariff. Do not mix those meetings up, which is the constraint I would write next to SolaX Triple Power for this small terrace.
SP Energy Networks covers this Edinburgh example. A 4 kWp-class roof at 870 kWh per kilowatt is about 2,610 kWh a year before shade, and SolaX Triple Power does not change that weather.
Money for SolaX Triple Power for a small terrace in Edinburgh
Take an 8 kWh pack, cycled about 300 times, at 90% round trip. Charge at 9.0p, and value what comes back at 28.4p. Export given up is priced at 8.0p. About 857 kWh a year of the charge is treated as spare solar from 2.5 kWp that might otherwise have been exported. Delivered energy is about 2160 kWh. After charging cost and lost export, the figure saves about £420 a year. Set that against £5,912 fitted, which is a September 2026 illustration at the temporary 0% residential rate, not a quote. That is a simple payback of about 14.1 years on these assumptions. Nudge the night rate up by 4p and see if you still like it.
Where the job is a qualifying install in a home, the 0% rate runs to 31 March 2027 and is due to become 5% after that. This figure prices the work at £5,912 on that basis. It does not apply to a shop, and it does not apply to a battery you buy and fit yourself.
Connection for SolaX Triple Power for a small terrace in Edinburgh
In Edinburgh, on SP Energy Networks, 5 kW sits above the 3.68 kW G98 line, so this wants a G99 application before anyone energises it. Export can still be capped. Agree that before the inverter is ordered. The figure uses 8 kWh and 2.5 kWp, which is enough to tell two quotes apart if they assumed something else.
In Edinburgh, the weak case for SolaX Triple Power is simple: Households whose priority is a widely recognised backup brand and a large certified-installer network.
Would I proceed with SolaX Triple Power for a small terrace in Edinburgh?
I would not pay the bulk of £5,912 before the DNO route for a 5 kW inverter is known.
I would proceed on SolaX Triple Power for a small terrace in Edinburgh only after the cupboard, the 5 kW connection route and the tariff gap are written down.
Common questions
Is the price on this page a quote?
No. £5,912 is a September 2026 illustration for a 8 kWh example at the temporary 0% residential rate. Your survey replaces it.
Will it stay on in a power cut?
Only if a gateway or essential-load board was designed and paid for. A standard grid-tied battery turns off with the grid. On this 8 kWh example the inverter is 5 kW, and backup is still a separate line.
What paperwork should I keep?
Keep the MCS certificate where the job is certified, the electrical certificate, the DNO record, the schematic, the warranty registration and a photo of the schedule. For an illustrated £5,912 job, that folder is part of what you bought.
What if the cheap rate is not 7p?
Then the figure changes. This page used 9.0p as a charge rate and 28.4p as the rate avoided. A smaller gap means a worse payback. Read the live tariff.

The figures above are a rough guide. An installer still needs to see your fuse board, where the battery will go, and whether you want power during a blackout.
