Worksop Solar Output Month by Month: When Does a Home Battery Actually Fill?
ElectriFusion Solutions · 15 October 2026
A Worksop household asking whether a battery is worth it usually gets an annual kWh figure in reply, which is the one number that does not answer the question. What matters is the month. This is a south-facing Worksop roof, every month, from the European Commission's PVGIS model.
A 4.85 kW array in Worksop, every month
| Month | Output | Average per day |

| Jan | 165 kWh | 5.3 kWh |
| Feb | 250 kWh | 8.9 kWh |
| Mar | 404 kWh | 13.0 kWh |
| Apr | 513 kWh | 17.1 kWh |
| May | 584 kWh | 18.8 kWh |
| Jun | 543 kWh | 18.1 kWh |
| Jul | 571 kWh | 18.4 kWh |
| Aug | 522 kWh | 16.8 kWh |
| Sep | 437 kWh | 14.6 kWh |
| Oct | 293 kWh | 9.5 kWh |

| Dec | 164 kWh | 5.3 kWh |
PVGIS 5.2, SARAH2 radiation database, Worksop town-centre coordinates, south-facing at 35°, 14% system losses, fetched 15 October 2026. Annual total 4,652 kWh (959 kWh per kW), about 2.1% less than Doncaster. Modelled averages, not a guarantee for any particular roof.
The best month here is May at 584 kWh (18.8 kWh a day) and the worst is Dec at 164 kWh (5.3 kWh a day), a ratio of 3.6 to one; that ratio, not the annual total, is what a battery has to live with.
For scale: PVGIS puts the in-plane irradiation on that roof at about 1,178 kWh per square metre a year, and the array converts it to 959 kWh per installed kilowatt; a Worksop household with the regional average evening load would see the battery cycle fully on about 214 days a year on these figures.
What that means for the battery
Take daytime usage off the top and a 5 kWh battery fills on days the roof makes about 10 kWh or more. In Worksop that is Mar, Apr, May, Jun, Jul, Aug, Sep on the monthly averages. A 10 kWh battery is a 16 kWh-a-day proposition from solar alone, which here means Apr, May, Jun, Jul, Aug.
From November to January the average is 5.8 kWh a day. A house that runs a fridge, a router, a kettle and some lighting through the day uses most of that as it arrives, so the battery sees a few hundred watt-hours of surplus, not five kilowatt-hours. That is not a fault with the battery or the panels; it is the latitude.
That something else is the grid
On a time-of-use tariff the battery charges in the cheap overnight window and discharges into the evening peak, every day of the year, solar or not. In the dark months that is the whole of its job in Worksop; in summer it is a top-up, because the roof has already filled it. The saving is the rate gap times the kilowatt-hours shifted, so ask for the tariff's night and peak rates before the battery's brochure.
The two savings do not stack on the same day: an overnight charge leaves the battery full when the roof starts generating, so a summer day earns the solar saving or the tariff saving, whichever applies.
So what size for a Worksop home?
Start from the smart meter, not the roof: a week of evening usage gives the number, and in Worksop that is usually 5 kWh for a three-bedroom house and 10 kWh where there is an EV or a heat pump to feed overnight. What the roof adds is the table above. Everything on the installation side, from G98 and G99 to standalone batteries, is on our battery storage Worksop page, and the panels on solar panels in Worksop.
Questions
Does a home battery work in winter in Worksop?
It works, but from the tariff rather than the roof: PVGIS gives a 4.85 kW array in Worksop about 5.8 kWh a day across November to January, most of which the house uses as it is generated. On a time-of-use tariff the battery charges overnight and runs the evening peak all winter.
Which months will a 5 kWh battery fill from solar in Worksop?
On the PVGIS monthly averages, Mar, Apr, May, Jun, Jul, Aug, Sep, when the roof makes 10 kWh or more a day after daytime use. A 10 kWh battery fills from solar alone in Apr, May, Jun, Jul, Aug.
