Is there enough sun around Bootle to make this work?

Modelled at 853 kWh per kWp a year for a shallow-pitched roof at this latitude, which puts a 500 kWp array at roughly 427,000 kWh a year before shading. That array needs about 1,485 sqm of clear roof once ridge vents and walkways are allowed for. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.

Who do we apply to for export near Bootle?

Only SP Energy Networks can answer it for your connection, and on rural feeders the answer varies farm to farm. An export-limited offer usually still works, because a holding with grain drying, cooling or ventilation uses most of what it makes.

Do we need planning permission in Liverpool?

In most cases no, because panels on the roof of an agricultural building usually sit within permitted development. The exceptions are listed buildings, conservation areas, protected landscapes and arrays that stand proud of the roof. We check with Liverpool either way.

Has anyone near L20 already done this?

The planning database records 0 ground mounted and 6 roof mounted solar schemes in this postcode district. That matters less as proof it works and more as evidence of how the local network has treated export applications. Roof arrays under a megawatt often never appear in the database, so the real figure is higher. Source: Renewable Energy Planning Database, Q1 2026.

Solar panels for farms in Bootle

Most holdings around Bootle already own the best generating site they will ever have, and it is the roof of the shed they built for something else. What decides a farm scheme here is the state of the roof sheets and the incoming supply, which is why the survey looks at both before anyone sizes an array.

853 kWh per kWp a year at this latitude, so a 500 kWp array models at about 427,000 kWh. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.

What a farm roof near Bootle generates

Modelled irradiation at this latitude is 1090 kWh per square metre a year in the plane of a shallow-pitched roof, which works out at 853 kWh for every kWp installed (EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss). That is about 4 percent below the mean across the areas we cover, so the case here rests on using the output on the holding rather than exporting it.

6 roof mounted schemes are on record nearby. Roof arrays under a megawatt frequently never reach that database at all, so the real number of farm roofs generating around Bootle is higher than the record shows.

Most of the buildings we look at here sit in the L postcode area.

Liverpool is the planning authority for most holdings here, and it is the authority that decides whether an array on an agricultural building falls inside permitted development.

FIG. 1 What a Bootle roof makes, month by month

May produces 7.7 times what Dec does on the same roof. A 500 kWp array here models at about 427,000 kWh across the year, but it arrives unevenly, which is why we size against your summer daytime load and then look at whether storage is worth adding for the shoulder months.

Bootle ranks 4 of 6 towns we cover in Merseyside on modelled yield, against a national mean of 886 kWh per kWp. The county runs from 830 to 877, a spread of 47 kWh per kWp. On a 500 kWp array that is about 23,500 kWh a year between the strongest and weakest town in the county.

Bars are zero based, so length is proportional to the figure. Where a county is flat, that is the finding: location is not the lever, consumption is. Source: EU PVGIS v5.2, modelled per town

Grid connection through SP Energy Networks

SP Energy Networks is the network operator here, and their answer on export capacity shapes the design. Any commercial array above 3.68 kW per phase connects under G99 rather than G98, and the application fixes what you are allowed to push back onto the network. If the local network is tight, limiting export rarely breaks the case here: most of the generation is consumed on site while the building is working.

Across Merseyside the planning database records 104 solar schemes totalling 98 MW, of which 1 are operational (REPD Q1 2026).
