Solar panels for farms in Maindee

Most holdings around Maindee already own the best generating site they will ever have, and it is the roof of the shed they built for something else. Each survey records the sheet type and condition, the usable area once rooflights and vents come out, and whether the supply is single or three phase.

What a farm roof near Maindee generates

Modelled irradiation at this latitude is 1167 kWh per square metre a year in the plane of a shallow-pitched roof, which works out at 910 kWh for every kWp installed (EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss). That sits within a few percent of the mean across the areas we cover, so what decides the scheme is your own demand pattern rather than the latitude.

No solar scheme is recorded in this postcode district in the planning database. On a farm that usually means nothing has been built above the reporting threshold rather than that nothing has been built, because a roof array on a shed rarely appears in it.

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

Jun produces 6.4 times what Dec does on the same roof. A 500 kWp array here models at about 455,000 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.

Maindee ranks 1 of 4 towns we cover in Newport on modelled yield, against a national mean of 886 kWh per kWp. The county runs from 887 to 910, a spread of 23 kWh per kWp. Within Newport that difference is small enough to ignore: where the building sits is not what decides this scheme, your consumption pattern is.

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
