Solar Panels Dundee – Compare Costs and Savings

Q: How much can I save with solar panels Dundee?

A 4kWp system in Dundee generates around 3,760 kWh a year . Using roughly 40% of that at home saves about GBP 393 off your electricity bill, and exporting the rest earns around GBP 338 through the Smart Export Guarantee - about GBP 731 a year in total. Being at home during the day, or adding a battery, pushes the bill saving higher.

Q: How much electricity will solar panels generate Dundee?

Roofs in Dundee produce about 940 kWh per kWp of panels each year , which is -1% vs the UK average. So a 4kWp array generates roughly 3,760 kWh and a 6kWp array around 5,640 kWh. Output is heavily seasonal: the months from April to September do most of the work, and a south-facing roof at around 30 degrees performs best.

Roofs in Dundee produce around 940 kWh per kWp installed each year. That puts a typical 4kWp system at about 3,760 kWh a year – worth roughly £731 a year off your electricity bill and in export payments.

Adding a battery?

A battery stores what you generate during the day so you use more of it yourself instead of exporting it. It costs more up front, so it lifts the yearly benefit but usually lengthens payback.

Estimates are based on an average 4-5 bedroom household with annual electricity usage of 4,200 kWh, using the July 2026 price cap rates. Electricity export rate of £0.15 per kWh. Payback is shown as a range because installed cost varies with roof type, scaffolding and array layout. Your own usage pattern matters more than any single figure here – a quote is the only way to pin it down.

What solar panels cost in Dundee

These are the ranges our installers actually quote, not list prices. The low end is a straightforward south-facing tiled roof; the high end covers split arrays, awkward access and in-roof mounting. The savings column is calculated using the 940 kWh/kWp figure for Dundee.

How we work these numbers out

We would rather show the method than ask you to trust a headline. Here is exactly where each figure comes from.

Sunlight where you live

The amount of electricity a roof produces is set mostly by how much sunlight reaches it, and that varies considerably across the UK. Working from MCS irradiance datasets (MIS 3002 Issue 6.0), due south at 35 degree pitch, cross-checked against PVGIS 5.3, Dundee comes out at 940 kWh per kWp installed, per year – -1% vs the UK average. It falls in MCS irradiance zone 15. The same panels on the same roof pitch generate meaningfully more in the far south than in the far north, which is why a single national estimate is not much use to you.

What that electricity is worth

Every unit you use yourself replaces one you would have bought at 26.11p per kWh under the July 2026 price cap. What you do not use is exported and paid for at around 15p per kWh through the Smart Export Guarantee. We assume 40% of what you generate is used at home without a battery, 75% with one.

What it costs to install

Cost ranges come from what installers on our network quote for real jobs, not from list prices. Payback is simply installed cost divided by yearly benefit, shown as a range so you can see both the good-roof and the difficult-roof case rather than only the flattering one.

Rates are held in one place and updated when Ofgem resets the cap in January, April, July and October – currently the July 2026 cap. Estimates are exactly that: your roof pitch, orientation, shading and usage pattern will move the answer, and only a survey settles it.

Getting solar installed in Dundee

Solar panels on a house roof in Dundee are normally permitted development, so most homeowners do not need planning permission. The usual exceptions are listed buildings, homes in a conservation area, and panels that would sit more than 200mm proud of the roof slope or above the highest part of the roof. If any of those apply to your property, a local installer will tell you at survey stage – it is a routine question, not a dead end.

Any installer worth quoting will be MCS certified. That certification is what makes your system eligible for Smart Export Guarantee payments from your electricity supplier, so it is not a nice-to-have. Every installer we pass your details to is MCS certified and covers Dundee.

Dundee sits in Scotland, which shapes the numbers on this page more than most people expect. Two identical 4kWp systems, one here and one at the other end of the country, can differ by several hundred kilowatt-hours a year purely on sunlight. That is why the figures above are worked out for Scotland rather than for the UK as a whole.

Your installer handles the grid connection paperwork with your local network operator. For a standard domestic system this is a notification after the work is done rather than an application you wait on, so it does not usually hold anything up.

What happens next. Tell us your postcode and a little about your roof, and we will match you with MCS-certified installers covering Dundee. You compare their quotes side by side and decide whether to go ahead. There is no charge and no obligation at any point.

Solar panels in Dundee: common questions

How much do solar panels cost Dundee?

A 4kWp system – the most common size for a three-bedroom home – typically costs £5,500 – £7,500 installed in Dundee. Smaller 3kWp systems start lower and 6kWp systems for larger homes or households with an EV run higher. Domestic solar is zero-rated for VAT, so the quoted price is what you pay. The spread within each size band comes down to roof type, scaffolding and how the array has to be laid out.

How much can I save with solar panels Dundee?

A 4kWp system in Dundee generates around 3,760 kWh a year. Using roughly 40% of that at home saves about £393 off your electricity bill, and exporting the rest earns around £338 through the Smart Export Guarantee – about £731 a year in total. Being at home during the day, or adding a battery, pushes the bill saving higher.

How much electricity will solar panels generate Dundee?

Roofs in Dundee produce about 940 kWh per kWp of panels each year, which is -1% vs the UK average. So a 4kWp array generates roughly 3,760 kWh and a 6kWp array around 5,640 kWh. Output is heavily seasonal: the months from April to September do most of the work, and a south-facing roof at around 30 degrees performs best.

What is the payback period on solar panels Dundee?

On these figures a 4kWp system in Dundee pays for itself in roughly 7.5 to 10.3 years, depending on what you pay to have it installed. Panels are generally warranted for 25 years and keep producing after that, so most of the system's life sits beyond the payback point. Rising electricity prices shorten payback; falling prices lengthen it.

Do I need planning permission for solar panels Dundee?

Usually not. Roof-mounted panels on a house are normally permitted development. You will need to check first if your home is listed or in a conservation area, or if the panels would project more than 200mm from the roof slope or sit above the highest part of the roof. An installer will flag any of this at survey stage.

Are the installers Dundee MCS certified?

Yes. Every installer we match you with is MCS certified and covers Dundee. MCS certification is what makes your system eligible for Smart Export Guarantee payments, so an uncertified install can quietly cost you the export income entirely.

Is it worth getting a battery Dundee?

A battery stores daytime generation so you use more of it yourself rather than exporting it at a lower rate. That lifts the annual benefit, but it adds £3,000 – £4,500 to the install, so payback usually gets longer rather than shorter. It tends to make most sense if you are out during the day, have an EV, or are on a tariff with cheap overnight rates. Ask for quotes both with and without and compare.
