Against Great Britain as a whole: Tilbury makes 1,057 kWh per kWp a year, and the mean of our 85 county PVGIS estimates (our GB average) is 925, so Tilbury is 14% above it.
How Tilbury compares
Small towns rarely get published solar figures, so here are the numbers for Tilbury. It is one of 46 Essex towns we track, and it ranks joint 26th of 46 for solar yield, a town of 14,951 people in the House of Commons Library settlement data. PVGIS gives its roofs 1,057 kWh per kWp a year, 2.90 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £941 of year one benefit, £247 of it from your own generation and £694 from export at 12p.
These are starting numbers, not a quote. The calculator below opens on Tilbury'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.
Planning applications here go through Thurrock; nationally, the House of Commons Library classes Tilbury 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.

UK Power Networks and your Tilbury connection
On NESO's licence-area map, Tilbury is in East England, which UK Power Networks operates. That makes UK Power Networks the network operator for any system fitted here.
Most home systems stay within 3.68kW per phase of inverter output, which puts them on G98, a notification to UK Power Networks within 28 days of switch-on. Panel count does not decide it; the inverter and any battery do.
Larger systems go through G99 instead, applied for before installation. On timing: 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 UK Power Networks as it does every network operator.

Adding a heat pump or an EV charger in Tilbury
A heat pump in Tilbury
In December, the darkest month here, 12 panels in Tilbury make about 240 kWh. That is when a heat pump runs hardest, so its running cost in Tilbury comes down to the tariff and the flow temperature rather than the roof.
Grant support in England comes from the Boiler Upgrade Scheme: £7,500 for an air source or ground source heat pump, £2,500 for air-to-air, and an extra £1,500 until March 2027 where the home is heated by oil or LPG off the gas grid (gov.uk, checked 28 September 2026).
Charging an EV in Tilbury
Summer is where a car earns its place. In July, 12 panels in Tilbury make about 830 kWh, against roughly 70 kWh a typical home uses in daylight that month on our calculator's typical-use settings, so there is surplus a smart charger can put into the car instead of exporting it.
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.

Tilbury solar questions
How much electricity do solar panels make in Tilbury?
About 6,720 kWh a year from 12 panels (6.36 kWp), on PVGIS satellite data for Tilbury: 1,057 kWh per kWp, or 2.90 peak sun hours a day on average. July is the strongest month, at about 830 kWh.
What does a typical solar system cost in Tilbury?
Solar is priced at £1,000 per kWp installed wherever you live, so a 12-panel, 6.36 kWp system costs £6,360 in Tilbury, exactly as it would anywhere else, before any battery. Location changes what the system makes, not what it costs: here that is about 6,720 kWh a year. The final figure comes from your roof on the design call.
Which DNO covers Tilbury, and what does it need from me?
UK Power Networks covers Tilbury. A home system of up to 3.68kW per phase is notified to UK Power Networks within 28 days of commissioning under G98, and nothing waits on approval. Larger outputs need a G99 application before work starts. 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 UK Power Networks as it does every network operator.
What happens to the solar I do not use in Tilbury?
Around £694 a year at 12p per kWh, for the roughly 5,786 kWh a 12-panel system in Tilbury exports with typical use. Rates vary by supplier and some need their own tariff; the export rates table is dated and sourced.
How much solar does Tilbury get in December?
December is the low point: about 240 kWh from a 12-panel system in Tilbury, on PVGIS data, rising to 830 kWh in July. From November to February the same system makes about 1,130 kWh in total, which is why a battery charged off-peak does more of the work in winter.
How Tilbury compares with its neighbours
The six closest towns we publish, run through the identical PVGIS query as Tilbury.
| Town | kWh per kWp a year | vs Tilbury |
|---|---|---|
| Tilbury | 1,057 | this town |
| Chadwell St Mary | 1,057 | level |
| Northfleet | 1,052 | −5 kWh |
| Grays | 1,055 | −2 kWh |
| Gravesend | 1,053 | −4 kWh |
| Swanscombe | 1,041 | −16 kWh |
| Chafford Hundred, West Thurrock and Purfleet-on-Thames | 1,052 | −5 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.
