Solar panels for warehouses in Newtown
Most of the industrial stock around Newtown carries a large, shallow-pitched roof that was never asked to do anything. The survey measures the roof, not the postcode: cladding profile, purlin centres, remaining sheet life and the load the frame can take.
820 kWh per kWp a year at this latitude, so a 500 kWp array models at about 410,000 kWh. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.

Distribution centre solar across Powys
What a roof in Newtown actually generates
Modelled irradiation at this latitude is 1045 kWh per square metre a year in the plane of a shallow-pitched roof, which works out at 820 kWh for every kWp installed (EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss). That is about 7 percent below the mean across the towns we cover, so the case here leans harder on how much you use on site rather than on raw generation.
We survey across the SY postcode area, starting from SY16.
Powys is the planning authority for most sites here, and the built-up area holds a population of about 10,885, so the stock here runs to trade counters, light industrial terraces and the occasional larger shed (ONS Census 2021 built-up areas).
Newtown ranks 6 of 6 towns we cover in Powys on modelled yield, against a national mean of 886 kWh per kWp. The county runs from 820 to 838, a spread of 18 kWh per kWp. Within Powys that difference is small enough to ignore: where the building sits is not what decides this scheme, your consumption pattern is.
Grid connection through National Grid Electricity Distribution
Connections around Newtown are handled by National Grid Electricity Distribution, which sets the export limit for the site. Above 3.68 kW per phase the connection runs under G99, so the export limit is agreed in advance rather than assumed. Where the local network is constrained, an export-limited connection usually still makes the scheme work, because a warehouse uses most of what the roof makes during the working day.
Across Powys the planning database records 18 solar schemes totalling 39 MW, of which 1 are operational (REPD Q1 2026).

Lenzie Consulting Ltd arranges the survey and passes your details to our MCS-certified installation partner so they can quote.
Questions about solar in Newtown
- What would a 500 kWp array produce in Newtown?
- Yes, and the number matters more than the sunshine. At 820 kWh per kWp a year, a 500 kWp array on a Newtown roof models at around 410,000 kWh. What changes the answer is how much of that you use on site rather than export. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.
- Which network operator handles the connection in Newtown?
- Applications go to National Grid Electricity Distribution, who run the network across Powys. They decide the export limit, and we handle the G99 paperwork alongside the array design.
- What does Powys require for rooftop solar?
- Roof-mounted panels on a commercial building usually fall under permitted development, subject to the limits on projection above the roof plane and to the building not being listed or in a conservation area. We confirm the position with Powys before the design is finalised.
