How Greenock compares
Among the places we publish figures for, Greenock is one of 11 Renfrewshire towns we track, and it ranks joint 9th of 11 for solar yield. It is a medium town in the House of Commons Library classification, with 37,758 residents, and its roofs see 2.25 peak sun hours a day across the year. That drives the standard 12 panel model to 5,215 kWh of generation, of which around 4,279 kWh is exported at 12p for £513 a year, with £247 saved on electricity you would otherwise buy at 26.32p.
These are starting numbers, not a quote. The calculator below opens on Greenock'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 Greenock, 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 Greenock
Greenock sits in SP Energy Networks' South and Central Scotland licence area, so SP Energy Networks is the network operator (DNO) any solar panels or battery here are registered with.
G98 is the simple route. If the inverter, plus any battery, stays at or under 3.68kW per phase, SP Energy Networks only has to be told within 28 days after the system is commissioned.
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 Greenock
A heat pump in Greenock
A heat pump does most of its work from November to February. Over those four months, 12 panels in Greenock make about 610 kWh, against 2,780 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 Greenock
From April to September, 75% of a Greenock roof's yearly output arrives, peaking at about 760 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.
If you rent, or own a flat, and have private off-street parking, the government chargepoint grant covers 75% of the cost, capped at £500 a socket, until 31 March 2027 (gov.uk, checked 28 September 2026). The calculator above prices a 7.4kW smart charger from £1,100 installed.

Greenock solar questions
What does a solar panel system produce in Greenock?
Each kWp of panels in Greenock makes 820 kWh a year on PVGIS figures, so a typical 12-panel system produces around 5,220 kWh, from about 90 kWh in December up to 760 kWh in May.
How much are solar panels in Greenock?
The price does not move by postcode. At £1,000 per kWp installed, 12 panels (6.36 kWp) come to £6,360 in Greenock before a battery. What Greenock changes is the return, about 5,220 kWh a year from that system, and your design call prices your actual roof.
Would a system in Greenock need approval from the network operator?
Greenock 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 Greenock?
With typical use and no battery, a 12-panel system in Greenock exports about 4,279 kWh a year. At 12p per kWh that is roughly £513; 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 Greenock in winter?
It works, but the year is lopsided. 75% of a Greenock roof's output lands between April and September; the four months from November to February give about 610 kWh on a 12-panel system. Payback is worked out on the whole year, not the winter.
How Greenock compares with its neighbours
The six closest towns we publish, run through the identical PVGIS query as Greenock.
| Town | kWh per kWp a year | vs Greenock |
|---|---|---|
| Greenock | 820 | this town |
| Gourock | 820 | level |
| Port Glasgow | 810 | −10 kWh |
| Helensburgh | 834 | +14 kWh |
| Dumbarton | 856 | +36 kWh |
| Bonhill and Renton | 846 | +26 kWh |
| Bishopton | 857 | +37 kWh |
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.
