How Port Glasgow compares
Small towns rarely get published solar figures, so here are the numbers for Port Glasgow. It is one of 11 Renfrewshire towns we track, and it ranks 11th of 11 for solar yield, a town of 16,773 people in the House of Commons Library settlement data. PVGIS gives its roofs 810 kWh per kWp a year, 2.22 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £753 of year one benefit, £247 of it from your own generation and £506 from export at 12p.
These are starting numbers, not a quote. The calculator below opens on Port Glasgow's own PVGIS figure; change the panels, the battery or the export rate and it reruns. The design call replaces every assumption with your roof and your bills.
Inverclyde is the planning authority covering Port Glasgow, which the House of Commons Library classes as a small 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.

Generation is modelled from PVGIS satellite data for Port Glasgow's own coordinates (55.93446, -4.69029), using the same 26.32p/kWh import value and £1,000 per kWp installed pricing as every Clearline estimate; the methodology is on our help page.
Who runs the grid in Port Glasgow
Port Glasgow is served by SP Energy Networks: the town's centre falls inside its South and Central Scotland licence area on NESO's boundary map.
Most home systems stay within 3.68kW per phase of inverter output, which puts them on G98, a notification to SP Energy Networks within 28 days of switch-on. Panel count does not decide it; the inverter and any battery do.
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.

Adding a heat pump or an EV charger in Port Glasgow
A heat pump in Port Glasgow
A heat pump does most of its work from November to February. Over those four months, 12 panels in Port Glasgow make about 400 kWh, against 2,850 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 Port Glasgow
From April to September, 78% of a Port Glasgow roof's yearly output arrives, peaking at about 770 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).

Port Glasgow solar questions
What does a solar panel system produce in Port Glasgow?
Each kWp of panels in Port Glasgow makes 810 kWh a year on PVGIS figures, so a typical 12-panel system produces around 5,150 kWh, from about 20 kWh in December up to 770 kWh in May.
How much are solar panels in Port Glasgow?
The price does not move by postcode. At £1,000 per kWp installed, 12 panels (6.36 kWp) come to £6,360 in Port Glasgow before a battery. What Port Glasgow changes is the return, about 5,150 kWh a year from that system, and your design call prices your actual roof.
Would a system in Port Glasgow need approval from the network operator?
Port Glasgow 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 Port Glasgow?
With typical use and no battery, a 12-panel system in Port Glasgow exports about 4,215 kWh a year. At 12p per kWh that is roughly £506; 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 Port Glasgow in winter?
It works, but the year is lopsided. 78% of a Port Glasgow roof's output lands between April and September; the four months from November to February give about 400 kWh on a 12-panel system. Payback is worked out on the whole year, not the winter.
How Port Glasgow compares with its neighbours
The six closest towns we publish, run through the identical PVGIS query as Port Glasgow.

| Greenock | 820 | +10 kWh |
| Dumbarton | 856 | +46 kWh |
| Helensburgh | 834 | +24 kWh |

| Bonhill and Renton | 846 | +36 kWh |
| Bishopton | 857 | +47 kWh |
Same PVGIS v5.2 query for every town. Small differences are within year-to-year weather; more than about 30 kWh per kWp apart is geography.
