Battery Storage in Mexborough
Battery storage for homes in Mexborough (S64), installed by our own MCS-certified engineers from Doncaster, 8 miles down the road. New solar plus battery, a retrofit battery, or a standalone unit charged from the grid: the right size depends on Mexborough's monthly solar figures and your evening usage, not on a brochure number, so those figures come first.
PVGIS puts a south-facing Mexborough roof at 968 kWh a year per kW of panels, about 1.3% less than Doncaster. A 4.85 kW array makes about 4,693 kWh a year here, 1.6% more than Rotherham. What that means for a 5 or 10 kWh battery, how the connection is registered with Northern Powergrid, and what City of Doncaster Council does and does not restrict are covered below.
How much a Mexborough roof can store
PVGIS 5.2 (the EU Joint Research Centre's model, SARAH2 radiation record, south-facing at 35°, 14% losses, fetched 15 October 2026) gives a 4.85 kW array in Mexborough these monthly totals:
| Month | Array output (4.85 kW) | Average per day |
|---|---|---|
| Jan | 164 kWh | 5.3 kWh |
| Mar | 410 kWh | 13.2 kWh |
| May | 586 kWh | 18.9 kWh |
| Jun | 550 kWh | 18.3 kWh |
| Jul | 576 kWh | 18.6 kWh |
| Sep | 435 kWh | 14.5 kWh |
| Nov | 208 kWh | 6.9 kWh |
| Dec | 162 kWh | 5.2 kWh |
The Mexborough figure to design around is the gap between 18.2 kWh a day across May to August and 5.8 kWh a day across November to January. A 5 kWh battery fills from the roof on ordinary summer days; in the three darkest months it fills only if a cheap overnight tariff does the charging.
The full twelve months, with what they mean for a 5 kWh and a 10 kWh battery, are in Mexborough solar output month by month.
Registering the battery with Northern Powergrid
Northern Powergrid is the network operator for Mexborough, so the battery is registered with it. What you register depends on the total inverter output at the property, including any existing solar inverter. Up to 16 A per phase in total, 3.68 kW on a single-phase supply, is a G98 notification after installation. Above that, for example a 5 kW hybrid battery inverter on a single-phase supply, a G99 application has to be approved before the system is switched on. We submit whichever applies, and it is on the quote.
Batteries on their own, and charging from the grid
A battery without panels can make sense in Mexborough where a roof is shaded, north-facing or not yours to change. HMRC's VAT Notice 708/6 zero-rates a battery supplied and installed in a home until 31 March 2027, and that expressly includes a standalone battery that stores electricity from the grid. It earns its keep by filling in the cheap overnight window of a time-of-use tariff and discharging into the evening peak; the saving is the gap between the two rates, multiplied by what the battery can shift each day.
If you also have panels, do not add grid-charging savings on top of solar savings for the same days: a battery filled from the grid overnight is already full when the morning's solar surplus arrives. Our battery storage page sets out the models we fit and their usable capacities.
Choosing a battery in Mexborough
Sizing starts with the evening, not the roof: the kilowatt-hours used between dusk and midnight are what the battery has to cover, and a week of smart-meter data settles it. Mexborough has approximately 6,500 households; the town averages about 1,370 hours of sunshine a year. A retrofit on existing panels counts the solar inverter towards the G98 limit, which is the usual reason a Mexborough retrofit becomes a G99 application.
Panels and battery together are priced on our solar panels in Mexborough page; the battery models are on battery storage: how it works.
Renting, planning and City of Doncaster Council
A wall-mounted battery inside the house, in a garage or in an outbuilding needs no planning permission; it is an electrical installation notified under Building Regulations, which we do through our competent-person registration. City of Doncaster Council is the planning authority for Mexborough, and listed buildings need consent for any external fixing. If you rent, your landlord's written agreement comes before anything is fixed to a wall.
Mexborough battery storage questions
Who do I register a Mexborough battery with?
Northern Powergrid is the network operator for Mexborough, so the battery is registered with it. Up to 3.68 kW of total inverter capacity per phase is a G98 notification after the install; above that it is a G99 application approved beforehand. We submit it.
Is a standalone battery worth it in Mexborough?
It can be, on the right tariff: the battery charges in the overnight window and runs the house through the evening peak, and the saving is the gap between the two rates on every unit shifted. VAT is 0% on a home battery, standalone included, until 31 March 2027 under HMRC's VAT Notice 708/6.
How much does a Mexborough roof make in winter?
About 5.8 kWh a day from a 4.85 kW array across November to January on the PVGIS averages, against 18.2 kWh a day from May to August. Most of the winter figure is used as it is generated, which is why a winter battery runs on an overnight tariff rather than on the roof.
