How Newton Mearns compares
Among the places we publish figures for, Newton Mearns is one of 11 Renfrewshire towns we track, and it ranks 8th of 11 for solar yield. It is a medium town in the House of Commons Library classification, with 29,608 residents, and its roofs see 2.27 peak sun hours a day across the year. That drives the standard 12 panel model to 5,279 kWh of generation, of which around 4,342 kWh is exported at 12p for £521 a year, with £247 saved on electricity you would otherwise buy at 26.32p.
Treat these as calibration rather than a quote. The calculator below runs the same model, opened on Newton Mearns' own yield, and prices a 12 panel system at £6,360 installed before any battery. Your free design call reworks every number for your actual roof, its shading and your usage.
East Renfrewshire is the planning authority covering Newton Mearns, which the House of Commons Library classes as a medium town.
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.

Who runs the grid in Newton Mearns
SP Energy Networks owns and runs the local electricity network in Newton Mearns, as part of its South and Central Scotland licence area.
What decides the paperwork is the inverter and battery output, not the number of panels. Up to 3.68kW per phase, a system follows G98: SP Energy Networks is notified within 28 days of commissioning and nothing has to be approved first.
Anything bigger is a G99 case and is applied for first. Ofgem's guaranteed standard for a low voltage generation connection quotation is 45 working days, with £80 paid for each working day late, and it binds SP Energy Networks as it does every network operator.

Heat pumps and EV charging in Newton Mearns
A heat pump in Newton Mearns
A heat pump does most of its work from November to February. Over those four months, 12 panels in Newton Mearns make about 710 kWh, against 2,710 kWh from May to August, so winter heating runs mostly on grid electricity and the tariff matters more than the roof.
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 Newton Mearns
From April to September, 72% of a Newton Mearns 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.
The calculator above includes a 7.4kW smart charger from £1,100 installed. Renters and flat owners with off-street parking can claim 75% of a chargepoint's cost, up to £500 per socket, until 31 March 2027 (gov.uk, checked 28 September 2026).

Solar in Newton Mearns: your questions answered
What does a solar panel system produce in Newton Mearns?
Each kWp of panels in Newton Mearns makes 830 kWh a year on PVGIS figures, so a typical 12-panel system produces around 5,280 kWh, from about 120 kWh in December up to 740 kWh in May.
How much are solar panels in Newton Mearns?
The price does not move by postcode. At £1,000 per kWp installed, 12 panels (6.36 kWp) come to £6,360 in Newton Mearns before a battery. What Newton Mearns changes is the return, about 5,280 kWh a year from that system, and your design call prices your actual roof.
Would a system in Newton Mearns need approval from the network operator?
Newton Mearns is on SP Energy Networks' network (South and Central Scotland licence area). Systems up to 3.68kW per phase of inverter output follow G98: SP Energy Networks is notified within 28 days of commissioning, with no approval needed first. Anything larger needs a G99 application before installation. Ofgem's guaranteed standard for a low voltage generation connection quotation is 45 working days, with £80 paid for each working day late, and it binds SP Energy Networks as it does every network operator. Our G98 vs G99 guide explains both routes.
How much can I earn from exporting solar in Newton Mearns?
With typical use and no battery, a 12-panel system in Newton Mearns exports about 4,342 kWh a year. At 12p per kWh that is roughly £521; a supplier paying more, or a battery that keeps more for the evening, changes the figure. See the export rates table.
Is solar worth it in Newton Mearns in winter?
It works, but the year is lopsided. 72% of a Newton Mearns roof's output lands between April and September; the four months from November to February give about 710 kWh on a 12-panel system. Payback is worked out on the whole year, not the winter.

PVGIS v5.2 for each town centroid, identical assumptions throughout. A few kWh either way is weather-year noise; a spread beyond about 30 kWh per kWp is real geography.
