Our GB average is 925 kWh per kWp a year, the mean of the 85 county PVGIS estimates we publish; at 760, Perthshire is 18% below it.
How Perthshire compares
Perthshire ranks 81st of the 85 counties we track for solar yield, 10% below the Scotland average of our estimates. Lower light changes the strategy rather than the answer: pair the array with off peak charging at 8.5p and the model still finds £714 a year on a typical 12 panel system, most of it from cutting 26.32p imports.
Every figure here assumes a clear, south-facing roof at 35 degrees in the middle of Perthshire. Yours will differ; the calculator below lets you test panels, batteries and export rates first.
The charger is in the installed price but left out of payback: charging savings depend on your mileage and tariff, which the design call models properly.

Generation from PVGIS v5.2 (European Commission JRC, SARAH3), retrieved August 2026 for a representative point in Perthshire (56.5206, -3.9588), assuming 1 kWp, 14% system loss, 35 degree pitch, due south. Import valued at 26.32p/kWh (Ofgem price cap average, Oct to Dec 2026); off-peak charging at 8.5p/kWh where used (a supplier's published off-peak rate, checked September 2026); export at the scenario you pick, from the dated tariff table. Prices are installed pricing, August 2026, standard installations; 530W LONGi panels at £1,000 per kWp. Estimates for illustration, not a quote: your free design call prices your actual roof.
Connecting solar to the Perthshire network
Scottish and Southern Electricity Networks (SSEN) is the distribution network operator (DNO) for Perthshire, running its North Scotland licence area.
For a typical home the paperwork is light: a system of up to 3.68kW per phase goes through G98, which means SSEN is notified within 28 days of switch-on rather than asked beforehand.
A bigger inverter or battery output needs a G99 application in advance. SSEN says it can take up to 45 working days to issue a quotation for a generation connection above 3.68kW per phase and up to 50kW.

Beyond the panels: heating and car charging in Perthshire
A heat pump in Perthshire
Solar and a heat pump pull in opposite directions through the year: Perthshire's roofs make 410 kWh from November to February on a 12-panel system, and 2,670 kWh from May to August. The heating season leans on the grid, so off-peak rates do the heavy lifting.
Scottish homes apply through Home Energy Scotland rather than the Boiler Upgrade Scheme: up to £7,500 in grant for a heat pump, up to £7,500 more as an optional interest-free loan, and a £1,500 uplift for rural and island homes (checked 28 September 2026).
Charging an EV in Perthshire
From April to September, 78% of a Perthshire roof's yearly output arrives, peaking at about 740 kWh in May on 12 panels. A car parked at home in daylight can soak up what the house, at around 70 kWh of daytime use that month, cannot.
Renters and flat owners with private off-street parking can get 75% off a chargepoint and its installation, up to £500 per socket, until 31 March 2027 (gov.uk, checked 28 September 2026). The calculator above adds a 7.4kW smart charger from £1,100 installed.

Solar in Perthshire: your questions answered
What could a roof in Perthshire generate?
PVGIS puts a roof in Perthshire at 760 kWh per kWp a year, 2.08 peak sun hours a day averaged across the seasons. A 12-panel, 6.36 kWp system makes about 4,830 kWh a year, most of it between April and September.
How much are solar panels in Perthshire?
The price does not move by postcode. At £1,000 per kWp installed, 12 panels (6.36 kWp) come to £6,360 in Perthshire before a battery. What Perthshire changes is the return, about 4,830 kWh a year from that system, and your design call prices your actual roof.
Do I need permission from the DNO for solar in Perthshire?
Usually not in advance. SSEN, the network operator for Perthshire, only needs a G98 notification within 28 days of commissioning for systems up to 3.68kW per phase. Bigger inverter or battery outputs need G99 approval first. SSEN says it can take up to 45 working days to issue a quotation for a generation connection above 3.68kW per phase and up to 50kW. "See our DNO explainer.
How much can I earn from exporting solar in Perthshire?
With typical use and no battery, a 12-panel system in Perthshire exports about 3,897 kWh a year. At 12p per kWh that is roughly £468; a supplier paying more, or a battery that keeps more for the evening, changes the figure. See the export rates table.
Do solar panels work in winter in Perthshire?
Yes, at a lower level. PVGIS gives Perthshire 4.5 kWh per kWp in December and 11.2 in January, so a 12-panel system makes about 30 kWh and 70 kWh in those months, against 740 kWh in May. Winter output mostly covers daytime use rather than exporting.
