Solar Panels Stevenage
Solar panels, battery storage and EV chargers for homes in and around Stevenage — designed from your actual usage, installed by an MCS-certified team, and explained in plain English before you commit to anything.
Stevenage was designated the first new town on 11 November 1946. Its master plan put housing to the east and industry to the west, in neighbourhoods each planned with their own shops, pub and community centre, around what the council's museum describes as the country's first completely pedestrian town centre. Eighty years on, that plan is written into the roofs. This page is a plain guide to solar panels Stevenage households can act on: what the town's terraces, council homes and conservation areas mean for an array, from the Old Town to Chells and Symonds Green.
We quote for homes in and around Stevenage, and the sunshine is ample for a well-sited array. The Met Office's long-term averages for the town use its Rothamsted station in Hertfordshire, which averaged about 1,621 hours a year over 1991–2020, and the European Commission's PVGIS tool puts a south-facing 4 kWp array in Stevenage at about 3,972 kWh a year. What decides the answer is your roof, how much power you use in the day and whether a battery is worth adding; our battery storage in Stevenage page covers that, and the official national price figures are on our solar panel installation cost page. If solar would not pay its way on your house, we will say so.
Quick answer
Solar panels in Stevenage:
- Cost: the Energy Saving Trust puts a typical 4.5 kWp home system (around 12 panels) at around £7,600 installed. Your own figure comes from a survey of your roof, not a table.
- Generation: PVGIS 5.3 estimates about 3,972 kWh a year from a 4 kWp south-facing array in Stevenage, around 993 kWh per kWp.
- Payback: on the Energy Saving Trust's table, with export payments and fuel prices as of July 2026, a London home pays back in about 9 years.
- VAT: residential solar installations carry 0% VAT until 31 March 2027, then 5% from 1 April 2027.
- Battery: the Energy Saving Trust puts a 5 kWh battery at around £4,600; fitting it with the panels costs less than a separate visit later.
- Who fits it: HCE is a NAPIT member (73495), MCS-certified for solar PV via NAPIT, and a HIES Consumer Code member. Check both registers yourself.

Solar on Stevenage's housing
Terraced houses are home to 44.9% of households in Stevenage's built-up area, according to ONS's Census 2021 figures — far more than any other type, ahead of flats and maisonettes (22.9%), semi-detached houses (19.8%) and detached houses (12.4%). The built-up area had 94,470 usual residents. A terrace roof is shared along the row, so scaffolding, cable runs and where the inverter goes are planned with the neighbours in mind. Tenure is the bigger constraint: 25.3% of the town's households rent from a social landlord and 15.1% rent privately or live rent-free, and at borough level 20.4% of Stevenage households rent from the council itself. That leaves about 59.6% owning outright or with a mortgage, loan or shared ownership (our sum of ONS's figures) — the households who can decide on panels for themselves.
Stevenage has seven conservation areas: Old Town High Street (designated 1969), Shephall Green (1973), Symonds Green (1977), St Nicholas/Rectory Lane (1982), the Town Square (1988), and Broadwater and Orchard Road (both 2007). The council's current Article 4 directions cover employment land in Gunnels Wood and Pin Green, confirmed on 21 January 2026, which removes rights to convert offices and light industrial units to housing, and the change of a house to a small HMO, confirmed on 24 May 2017 — nothing that touches a householder's roof. So the national rule applies: under Class A of Part 14 of the GPDO as amended from 27 August 2026, a conservation area excludes only equipment on a wall, balcony or roof enclosure fronting a highway; roof slopes, front ones included, stay permitted development within the 0.2 m and roof-height limits, a flat roof in a conservation area needs a prior-approval determination, and a listed building needs listed building consent. Green belt covers just 6.9% of the borough. On efficiency, ONS puts Stevenage's median EPC score at 70, with 60.1% of dwellings at band C or above; terraced and semi-detached houses both sit at a median 69, the bottom edge of band C.
What Stevenage Borough Council is doing
Stevenage Borough Council declared a climate emergency on 12 June 2019 and set a target for Stevenage itself — not only the council — to have net-zero emissions by 2030. A Climate Change Strategy, co-produced after consultation with residents and stakeholder groups, followed in September 2020, and progress on its action plan is published on the council's Stevenage Climate Action Plan website.
Group buying has come through Solar Together Hertfordshire, which the council brought to residents in partnership with the Hertfordshire Climate Change and Sustainability Partnership and iChoosr; the 2025 round's deadline was extended to 25 April 2025. On 15 October 2026 the scheme, now Switch Together, said it was not active in Stevenage and offered registration for the next one. Income-linked help comes through the Warm Homes: Local Grant: the council received £1.5 million, works with the National Energy Foundation, and lists insulation and solar panels among the measures for privately owned or privately rented homes rated EPC D to G that meet the income, benefits or deprivation test. For landlords, one eligible home per landlord can be fully funded, with a 50% contribution required for any further homes.
What solar costs on a Stevenage home
The honest national anchor is the Energy Saving Trust's: a typical domestic system is around 4.5 kWp — roughly around 12 panels over 20 to 30m² of roof — and costs around £7,600 installed. On their payback table, with export payments and fuel prices as of July 2026, London homes sit at about 9 years. With 44.9% of Stevenage households in terraced houses, whether a roof offers the 20 to 30 m² that the Energy Saving Trust's typical system covers is the first thing the survey checks on a new-town terrace.
Two things move that number for everyone. Residential installations carry 0% VAT until 31 March 2027, reverting to 5% from 1 April 2027. And export payments under the Smart Export Guarantee are set by each supplier and must be above zero — they change on short notice, which is why we never print one. A quote should itemise the panels, inverter, mounting, scaffolding, labour, commissioning, warranties and the DNO notification, so you can see what the total is made of — ours does, and it comes from a survey of your actual roof and usage, not from a table.

When we'd tell you not to fit solar in Stevenage
A persistently shaded roof, a slope that faces mostly north, a listed building where consent will not carry the fixings, or a home whose daytime usage is so low that almost everything would be exported at a supplier-set rate — in those cases we will say so at the survey rather than sell you a system that under-delivers. Fabric-first improvements sometimes beat panels as the first spend, and we would rather tell you that than not.
Whoever you use, check the registers yourself: HCE is NAPIT member 73495 and an HIES Consumer Code member (HCE/A/1392), with MCS certification for solar PV via NAPIT — the certification an MCS-certified install needs for Smart Export Guarantee payments.
What a Stevenage roof actually generates
Rather than quote a generic yield, we ran the European Commission's PVGIS 5.3 (European Commission Joint Research Centre) for Stevenage itself. A 4 kWp array at 35° facing due south, with 14% system losses, is estimated at about 3,972 kWh a year — around 993 kWh per kWp — with a year-to-year variation of roughly ±154 kWh (PVGIS-SARAH3, 2005–2023). East- or west-facing slopes generate less, and shading changes the answer more than the town does; that is exactly what the survey measures.
Method: PVGIS 5.3 (European Commission Joint Research Centre), 4 kWp, 35° tilt, due south, 14% system losses, building-mounted, run 2026-10-15.

Stevenage solar questions
Do I need planning permission for solar panels in Stevenage?
Rarely. Since 27 August 2026, Class A of Part 14 of the GPDO excludes, in a conservation area, only equipment on a wall, balcony or roof enclosure fronting a highway; roof slopes, front ones included, stay permitted development provided panels sit no more than 0.2 m proud of the slope and no higher than the highest part of the roof, chimneys aside. Stevenage has seven conservation areas, from Old Town High Street to Broadwater and Orchard Road, and a flat-roof array inside one needs a prior-approval determination first. The council's current Article 4 directions cover employment sites in Gunnels Wood and Pin Green and the change of a house to a small HMO, so none affects a householder's roof. Listed buildings always need listed building consent.
I rent my Stevenage home — can I still get solar?
Only with your landlord's agreement, and that is a large group here: 25.3% of households in the town rent from a social landlord and 15.1% rent privately or live rent-free, and across the borough 20.4% rent from the council itself (Census 2021). Council tenants would need to raise it with the council as landlord. For private landlords, Stevenage's Warm Homes: Local Grant can fully fund one eligible home per landlord, with a 50% contribution for further homes, where the home is rated EPC D to G and the household meets the income, benefits or deprivation test — and the council lists solar panels among the possible measures.
What would solar generate on a Stevenage roof, and what does it cost?
PVGIS 5.3, run for Stevenage on 15 October 2026, estimates about 3,972 kWh a year from a 4 kWp array at 35° facing due south with 14% losses — about 993 kWh per kWp — give or take roughly ±154 kWh between years (PVGIS-SARAH3, 2005–2023). Ofgem's typical domestic consumption value from 1 July 2026 is 2,500 kWh a year. The Energy Saving Trust puts a typical 4.5 kWp system of around 12 panels, covering 20 to 30 m² of roof, at around £7,600 installed, and residential installations carry 0% VAT until 31 March 2027. Whether your terrace roof offers that much unshaded space is what the survey checks.
Is Solar Together running in Stevenage?
Not at the moment. Stevenage Borough Council partnered with the Hertfordshire Climate Change and Sustainability Partnership and iChoosr to offer Solar Together Hertfordshire, and its 2025 round's deadline was extended to 25 April 2025. On 15 October 2026 the scheme — now Switch Together — said it was not active in Stevenage and invited residents to register for the next one. Registering and getting an independent quote are not mutually exclusive; what matters is comparing the two on the same specification of panels, inverter, battery and warranties.
