Why Go Solar in Barnstaple?

Barnstaple sits on the north coast of Devon, in a part of the country that benefits from strong levels of sunshine by UK standards. North Devon receives approximately 1,500-1,600 hours of sunshine per year, with the sunniest months – June and July – averaging around 7-8 hours of sunshine per day. Even in the shorter winter months, modern solar panels generate meaningful electricity from daylight alone – they don’t just rely on direct sun.

At the same time, UK electricity prices remain significantly higher than their pre-2022 levels. The Ofgem price cap for Q2 2026 set the average electricity unit rate at 24.67p/kWh, and although rates have come down from their 2022-2023 peak, they are still around 35% above where they were before the energy crisis began. For Barnstaple households, that makes self-generated solar electricity considerably cheaper than buying from the grid.

A typical 4 kW residential solar system saves approximately 1.6 tonnes of CO₂ per year – equivalent to driving roughly 4,000 miles in a petrol car. Over a 25-year panel lifespan, that adds up to a substantial environmental contribution alongside the financial savings.

How Much Do Solar Panels Cost in Barnstaple?

The cost of a solar panel system depends on the size of the system, the complexity of your roof, and whether you choose to add battery storage. Here is a guide to typical costs for residential installations in Barnstaple:

System Size (approximate) Number of Panels Typical Cost Annual Generation Estimated Annual Savings
3 kW 6 £4,500 2,800 to 3,200 kWh £500 to £700
4 kW 8 £5,500 3,800 to 4,200 kWh £650 to £850
5 kW 10 £6,000 4,700 to 5,200 kWh £800 to £1,000
6 kW 12 £6,500 5,600 to 6,300 kWh £950 to £1,200

Note: These figures are indicative and based on south-facing roof installations. Actual costs depend on your specific property, and savings depend on your electricity usage patterns and how much generated power you use directly versus export. We provide detailed, personalised projections as part of our free survey.

For reference, a typical 5 kWh battery suitable for a 4 kW solar system adds approximately £1,300 to £2,500 to your installation cost. Larger capacities (10 kWh+) are available for homes with higher energy consumption.

What Affects the Cost?

No two installations are the same. The final price depends on several factors, including the number and type of panels (for example, SunPower panels typically cost more than JA Solar panels, but offer higher efficiency and longer warranties), whether your roof requires additional scaffolding or access arrangements, the complexity of the electrical work involved, and whether you are adding battery storage or an EV charger at the same time.

This is exactly why we carry out a free, in-person property survey before providing a fixed-price quote. Unlike some national providers who rely on satellite images, our surveyor visits your property to assess roof orientation, shading, structural suitability, and your specific electricity usage. You’ll receive a clear, detailed quote with no hidden costs.

Typical Savings and Payback Period

To give you a sense of the financial return, here is a worked example for a typical Barnstaple home:

Example: 3-bedroom semi-detached house in Barnstaple with an 8-panel (roughly 4 kW) solar system and 5 kWh battery:

  • Total system cost: approximately £6,800-£7,000 (£5,500 for panels plus approximately £1,300-£1,500 for the battery)
  • Estimated annual generation: approximately 3,800-4,200 kWh
  • Estimated annual bill saving: approximately £800-£1,050 (higher than a solar-only system because the battery allows you to use more of your generated electricity on-site rather than exporting it)
  • Smart Export Guarantee (SEG) income: approximately £30-£70 per year (lower than a solar-only system because less electricity is exported; rates vary by supplier)
  • Estimated payback period: approximately 6-8 years
  • Panel lifespan: 25-40 years, depending on the panel brand

After the system has paid for itself, every unit of electricity it generates is effectively free. Over a 25-40 year lifespan, the total savings can run well into the tens of thousands of pounds.

What We Install

Simple Solar provides a complete renewable energy service for Barnstaple homeowners. Here’s what we offer:

01

Solar Panels

We install high-quality solar panels from leading manufacturers. Our most popular option is SunPower – we’re one of a small number of UK installers to hold SunPower Premier Partner status.

SunPower panels offer industry-leading efficiency, with product and performance warranties of up to 40 years. If there is another make or model you are interested in, just let us know and we can compare and contrast with SunPower.

Every system is designed around your roof, your electricity usage, and your budget. We’ll recommend the right panel for your situation. We don’t push premium products where they’re not needed. Learn more about our residential solar panels.

02

Battery Storage

Adding battery storage to your solar system allows you to store surplus electricity generated during the day and use it in the evening or overnight, rather than exporting it to the grid for a few pence per unit. This significantly increases the proportion of solar electricity you use on-site, which is where the real savings lie.

We install a range of battery systems including the Tesla Powerwall 3 and other leading options. We can include battery storage with a new solar installation, or retrofit a battery to an existing system. If you’re not sure whether a battery is right for you, we’ll give you an honest assessment – for some households, panels alone deliver the best return on investment.

03

EV Chargers

If you have an electric vehicle – or plan to get one – charging it from your solar panels is one of the smartest ways to reduce running costs. A solar-charged EV can cost as little as 2-3p per mile to run, compared with around 7-8p per mile from grid electricity and significantly more from a petrol or diesel car. We install home EV chargers that integrate with your solar and battery system, giving you maximum control over your energy use.

01

Step 1: Free Home Survey and Consultation

Everything starts with a free, no-obligation home survey. One of our experienced surveyors will visit your property to assess its suitability for solar panels. This typically takes around an hour and covers:

  • Roof assessment: orientation, pitch, condition, and available space
  • Shading analysis: identifying any obstructions that could affect performance
  • Electrical inspection: checking your consumer unit and existing electrical setup
  • Energy usage review: understanding your current consumption patterns
  • Discussion of your requirements and any questions you have

There is no hard sell. We will give you an honest assessment of whether solar is right for your property and, if so, what size system would best suit your needs.

02

Step 2: Detailed Quote and System Design

Following the survey, we prepare a detailed written quotation including:

  • Recommended system specification (panel type, inverter, optional battery)
  • Itemised costs with nothing hidden
  • Estimated annual generation based on your specific roof
  • Projected savings and payback period
  • Available warranty information

We will talk you through the quote and answer any questions. Take your time to consider – we never pressure customers into quick decisions.

03

Step 3: Planning and DNO Notification

Once you decide to proceed, we handle all the paperwork. Most residential solar installations fall under permitted development and do not require planning permission (see below), but we will confirm this for your property.

We submit the necessary notification to your Distribution Network Operator (DNO), typically SSEN for the Barnstaple area. For systems under 3.68 kW, this is a simple notification. Larger systems may require a formal application under G99, which can take a few weeks for approval. We manage this entire process on your behalf.

04

Step 4: Installation Day

Installation day is when the real work happens. For a typical residential system, installation takes one to two days. Here is what to expect:

  • Scaffolding is erected (usually a couple of days before installation)
  • Our team arrives at the agreed time with all the equipment and materials
  • Mounting rails are fixed to your roof
  • Solar panels are fitted and secured
  • Cabling is run from the roof to your inverter location (often the garage or utility area)
  • The inverter is installed and connected to your consumer unit
  • The system is tested and commissioned

Our installers are respectful of your home. We keep disruption to a minimum, protect your floors and furnishings, and leave the site clean and tidy.

05

Step 5: Commissioning and Handover

Before we leave, we thoroughly test your system to ensure everything is working correctly. We will then walk you through:

  • How to read your inverter display and understand generation data
  • Setting up any monitoring app so you can track performance on your phone
  • How the system integrates with your household electricity
  • What to do if you notice any issues

You will receive a comprehensive documentation pack including your MCS certificate, warranty information, electrical certificates, and all the paperwork needed to register for the Smart Export Guarantee.

Typical timeline: From initial enquiry to completed installation usually takes 3 to 6 weeks, depending on survey availability and DNO approval times.

Do I Need Planning Permission for Solar Panels in Barnstaple?

In most cases, no. Domestic solar panel installations are classified as ‘permitted development’ under planning law, meaning you can install them without applying for planning permission from North Devon Council, provided the following conditions are met:

  • The panels do not protrude more than 200mm from the roof surface.
  • The panels do not extend above the highest part of the roof (excluding the chimney).
  • The installation is positioned to minimise visual impact on the building and surrounding area.

For most Barnstaple homes with standard pitched roofs, these conditions are easily met.

However, there are some situations where you should check with your local planning authority:

Listed buildings: If your property is a listed building, you will need listed building consent before installing solar panels.

Conservation areas: Barnstaple has several conservation areas, including parts of the town centre. In these areas, wall-mounted solar panels visible from the highway require planning permission. Roof-mounted panels are generally unaffected, but it’s worth confirming.

Proximity to Exmoor National Park: Properties within or near the boundary of Exmoor National Park may face additional considerations regarding visual impact on the landscape. Solar panels are not prohibited in the National Park, but the planning authority is particularly attentive to how installations affect the character of the area.

We check all planning requirements as part of our free property survey, so you’ll know exactly where you stand before committing to anything.

Check the official Planning Portal guidance for solar panels.

Considering Solar and a Heat Pump for Your Barnstaple Home?

If you’re also thinking about modernising your home heating, combining solar panels with an air source heat pump is one of the most effective approaches. A heat pump uses electricity to extract heat from the outdoor air and deliver it into your home via radiators or underfloor heating. When that electricity comes from your solar panels, your heating costs drop dramatically.

Simple Solar installs air source heat pumps alongside our solar and battery systems. The Boiler Upgrade Scheme (BUS) currently offers a government grant of £7,500 towards the cost of a qualifying air source heat pump installation – rising to £9,000 from July 2026 for homes currently heated by oil or LPG.

This is particularly relevant for many North Devon homeowners who are off the gas grid. The scheme is available to homeowners in England and Wales who are replacing an existing fossil fuel or direct electric heating system.

If a combined solar and heat pump system is something you’d like to explore, we can assess both during your property survey and design a package that works for your home.

Frequently Asked Questions About Solar Panels in Barnstaple

01 How much do solar panels cost in Barnstaple?

A typical residential solar panel system for a 3-bedroom home in Barnstaple costs between £5,000 and £6,500 including installation, depending on the number of panels and the brand chosen. Adding battery storage typically costs an additional £1,300 to £2,500. All prices include supply, installation, scaffolding, and electrical work. VAT is currently 0% on qualifying residential installations until 31 March 2027. We provide free, no-obligation quotes after an in-person property survey.

02 Are solar panels worth it in Barnstaple?

Yes. Barnstaple receives strong sunshine levels for the UK, and modern high-efficiency panels generate useful electricity even on cloudy days. A well-designed system typically pays for itself within 5-7 years through bill savings and Smart Export Guarantee income, then continues to deliver savings for decades. With electricity prices remaining well above pre-2022 levels, the financial case for solar in Barnstaple is compelling.

03 Do solar panels work in cloudy weather?

Yes. Solar panels generate electricity from daylight, not just direct sunshine. Output is lower on overcast days, but modern panels still produce meaningful energy. The UK’s cooler temperatures also help – solar panels actually operate more efficiently in mild conditions than in extreme heat, which is one reason why the south-west performs well for solar generation.

04 How many solar panels do I need for my home?

This depends on your electricity consumption, available roof space, and roof orientation. As a general guide, a typical 3-bedroom home in Barnstaple would benefit from a system of 8-10 panels (approximately 4-5 kW). A larger home or a household with an electric vehicle or heat pump may need 12 panels or more. Our free property survey will assess your specific situation and recommend the right system size.

05 Do I need planning permission for solar panels in Barnstaple?

In most cases, no. Domestic solar panel installations are classed as permitted development, provided the panels don’t protrude more than 200mm from the roof surface or extend above the highest part of the roof. Exceptions apply to listed buildings and some properties in conservation areas or within Exmoor National Park. We check all planning requirements during our free survey.

06 Can I add a battery to my solar panel system?

Yes. Battery storage allows you to store surplus solar electricity generated during the day for use in the evening or overnight, increasing the amount of free solar energy you use in your home. We can include a battery with a new installation or retrofit one to an existing solar system. Popular options include the Tesla Powerwall 3.

07 What is the Smart Export Guarantee?

The Smart Export Guarantee (SEG) is a government-backed scheme that requires licensed energy suppliers to pay you for surplus electricity you export to the grid from your solar panels. It replaced the Feed-in Tariff in January 2020. To qualify, your installation must be MCS-certified – which every Simple Solar installation is – and your property must have a smart meter. Export rates vary by supplier; we’ll advise you on which providers currently offer the best rates.

08 How long does solar panel installation take?

Most residential installations are completed in 1-2 days. The total timeline from your initial enquiry to a fully working system is typically 3-6 weeks, depending on survey availability, DNO permission, and our installation schedule.

09 Will solar panels damage my roof?

No. Our trained roofing engineers and electricians install panels using industry-standard mounting systems that are designed to protect the integrity of your roof. We carry out a structural assessment as part of the survey, and we’ve installed systems on roofs of all types: slate, tile, flat, and more. If your roof needs any minor repairs before installation, we’ll let you know upfront.
