Solar Panels Arundel: Installers for BN18
Solar, battery storage and EV charging in Arundel — designed and installed by a local, MCS-certified team based in Portsmouth.
Quick answer
Arundel (BN18) is on SSEN's network, not UKPN, and we file the G98 or G99 application for you. PVGIS models about 4,594 kWh a year for an unshaded 4kW south-facing array here - one of the strongest figures on our patch - and the conservation area carries no Article 4 direction.
Arundel sits on the River Arun in West Sussex, below the castle and cathedral that dominate its skyline, with Littlehampton and the coast a short run south and Chichester to the west. It is a small town with a large proportion of older and listed buildings, which makes the design conversation here about discretion and roof slope rather than panel count.
For solar the headline is the sunshine: PVGIS models one of the highest yields of any town we cover. Arundel is about 23 miles from our Portsmouth base, on the same coastal route we already work along at Chichester, Bognor Regis and Littlehampton, so surveys and installs here are local rather than a planned expedition.
Solar in Arundel: the local detail
Grid connection (DNO)
Arundel is in the SSEN (Scottish and Southern Electricity Networks) area: our postcode checks put BN18 in the Southern region, the same operator as Chichester and Hampshire, with UK Power Networks taking over further east. G98 covers smaller systems; G99 (applied for in advance) covers batteries and larger arrays - SCSS files the application.
Local planning authority
Arun District Council
Heritage & conservation
The national planning register records the Arundel conservation area with no Article 4 direction over it, so panels on the roof slope of a house there normally keep permitted development. Walls, balconies and roof enclosures fronting a highway are excluded, a flat-roof array needs prior approval, and listed buildings need consent checked before design - which in Arundel is the first thing to establish for your address.
Local housing stock
A compact historic core with Victorian and later housing around it and newer development towards the edges. HM Land Registry's July 2026 averages for Arun district were £321,460 overall, £553,083 for detached houses, £351,872 for semi-detached, £275,977 for terraced homes and £167,469 for flats.
Typical roofs
PVGIS 5.3 gives a 4kW unshaded array about 4,594 kWh a year facing south, 3,564 facing east and 3,615 facing west - west-facing roofs edge out east-facing ones here. We check every roof for shading at the survey and design discreetly where the conservation area applies.
Sunlight & generation
PVGIS models about 4,594 kWh a year for a 4kW unshaded, south-facing array at a 35° pitch

Solar Panels Arundel: BN18 Yields, the Conservation Area and the SSEN Connection
Arundel gets more sun than most of the places we quote for. PVGIS 5.3, the European Commission's model built on satellite data from 2005 to 2023, puts a 4kW unshaded, south-facing array here at about 4,594 kWh a year - ahead of Southampton (4,255) and well ahead of inland Surrey, where Godalming models at 4,122. East-facing it gives about 3,564 kWh and west-facing about 3,615 kWh, so west-facing roofs edge out east-facing ones on this stretch of the coast. Roughly 3,133 kWh of the year arrives between April and September, with about 567 kWh in June against 153 kWh in December.
The planning position is more forgiving than the town's appearance suggests. The national planning register records the Arundel conservation area and no Article 4 direction over it, and the register returns no national park or AONB designation at the town centre either. Without an Article 4 direction, panels on the roof slope of a house inside the conservation area normally keep permitted development under the rules as amended on 27 August 2026. What is excluded is a wall, balcony or roof enclosure fronting a highway; a flat-roof array needs prior approval first; and listed buildings sit outside householder rights altogether, which in a town with this much listed fabric is the first thing to establish for your specific address.
Arundel is on SSEN's network, not UK Power Networks - BN18 sits in the Southern region, the same operator as Chichester and Hampshire, with UKPN taking over further east along the coast. That also sets your export region: on 25 September 2026 Octopus Flux paid 29.00p per kWh here for exports between 4pm and 7pm, about 10.08p through the day and 4.74p between 2am and 5am, while Outgoing Octopus pays a flat 12p. A solar-only system up to 3.68kW per phase is notified under G98 after commissioning; a battery or a larger array needs G99 approval from SSEN first, and we file the application.
On housing, HM Land Registry put the Arun district average at £321,460 in July 2026, with detached homes at £553,083, semi-detached at £351,872, terraced at £275,977 and flats at £167,469. In practice that means two conversations: a straightforward 10 to 14 panel array on the newer housing around the edges of the town, and a careful, discreet, rear-slope design on the older stock below the castle. Arundel is about 23 miles from our Portsmouth base, on the same coastal run as solar panels Chichester and Littlehampton.

Do I need planning permission for solar panels in Arundel's conservation area?+
For a house, usually not on the roof slope. The national planning register records the Arundel conservation area with no Article 4 direction over it, and without one the roof slope keeps permitted development. The exceptions are a wall, balcony or roof enclosure fronting a highway, a flat-roof array (which needs prior approval), and listed buildings, which need consent checked before any design - worth establishing early in a town with this much listed fabric.
How much does a 4kW system generate in Arundel?+
PVGIS models about 4,594 kWh a year for a 4kW unshaded, south-facing array at a 35 degree pitch - about 567 kWh in June and 153 kWh in December, with roughly 3,133 kWh of the total arriving between April and September. That is one of the higher figures on our patch.
