How much do solar panels cost in Norfolk in 2026?

It's the first question almost everyone asks, and the honest answer is "it depends on your roof" - but that's not much help when you're just trying to work out whether solar is worth looking into. So here are realistic 2026 figures for a typical home in Norfolk and Suffolk, what pushes the price up or down, and what you get back.

Typical installed cost by system size

These are ballpark all-in prices for a standard on-roof system - panels, inverter, mounting, scaffold, wiring, certification and DNO notification - fitted on a straightforward pitched tiled roof:

• 3 kW (around 7-8 panels) - roughly £4,500-£6,000
• 4-5 kW (10-13 panels, the most common domestic size) - roughly £6,500-£8,500
• 6 kW+ (15+ panels) - roughly £8,500-£11,000
• Add a battery - commonly £3,000-£6,000 on top depending on capacity and brand

Domestic solar is currently 0% VAT, so those figures are what you pay, not ex-VAT.

What moves the price

What you get back

Lower bills. A 4 kW system generating in the region of 3,400-3,800 kWh a year typically saves a household somewhere around £450-£900 a year, depending on how much electricity you use during daylight. The more you shift usage to sunny hours - or add a battery - the more of your own generation you keep.

Export payments. Electricity you generate but don't use is sold back to the grid under the Smart Export Guarantee (SEG). Rates vary by supplier and tariff, commonly in the region of 12-15p per kWh on the better tariffs. You need an MCS certificate to claim, which every Wave Renewables installation carries.

Payback

For a typical on-roof system without a battery, payback in 2026 tends to land somewhere around 7-10 years, against a panel lifespan of 25+ years. A battery lengthens the payback on that element but increases your total saving. In-roof adds a little to the payback unless it's going on during a re-roof anyway.

Does solar actually work in Norfolk?

Yes - better than most of the UK, in fact. East Anglia is one of the driest, sunniest regions in the country, and Norfolk and Suffolk get more annual solar irradiance than the Midlands, the North or Scotland. A south-facing roof at a 30-40° pitch is ideal, but east-west roofs still perform at around 85-90% of that and spread generation across the morning and afternoon, which often matches how a household actually uses power.

Getting an accurate figure

Every one of the numbers above is a guide. The only way to know what your roof costs is a site visit - roof measurement, orientation and shading check, a look at your consumer unit and your recent bills. We do that for free across Norfolk and Suffolk and give you an itemised quote. See how it works or book a visit.
