Solar Panel Installers in Dorset

Solar, battery storage and EV charging across Dorset — MCS-certified, locally based, with your grid connection handled for you.

Quick answer

Dorset sits in the SSEN distribution area and enjoys high south-coast sun-hours. The Bournemouth–Poole conurbation has a large owner-occupier market well suited to solar and battery storage, with typical 4–6kW systems costing £5,000–£9,000.

Dorset combines a large, solar-suited housing market around the Bournemouth, Poole and Christchurch conurbation with some of the highest sun-hours on the South Coast. From retiree bungalows to Sandbanks waterfront homes, it is excellent solar territory.

Dorset properties connect through SSEN, and we manage the G98/G99 grid application as standard. We serve the eastern Dorset coast as a natural extension of our Hampshire heartland.

Grid connection (DNO)

West-facing

~3,300–3,700 kWh

Grants & export income

Be realistic on grants: most Dorset homeowners won't qualify for capital grants, so the Smart Export Guarantee (SEG) is the main ongoing earner. SEG is Ofgem-mandated — every large supplier must pay you for the surplus you export, and as of mid-2026 tariffs pay roughly 10.5p–16.5p per kWh on the open market — Octopus Outgoing pays 12p, cut from 15p to 12p on 1 March 2026, and the headline 25p-plus rates you may see quoted are either closed to new customers or conditional on buying your system through that supplier (each supplier sets and can change its own rate, and you can hold your export tariff with a different supplier than your import one; it needs an MCS-certified install and a smart export meter, both of which we sort). Means-tested help such as ECO4 and the Warm Homes scheme, plus any Solar Together Dorset group-buy rounds when they run, can help lower-income or specific-EPC households — but eligibility is narrow, so treat SEG plus the county's high sun-hours as the dependable return and check any grant scheme against its current criteria before assuming you qualify.

FAQ

Solar panels in Dorset: FAQs

How much do solar panels cost in Dorset?
A typical home system across Dorset costs from around £5,500–£11,000 depending on size and battery storage, with 0% VAT on residential solar. ~1,090–1,120 kWh/kWp per year — a 4kW system generates around 4,000–4,400 kWh. Every quote is tailored to your roof after a free survey.
Which electricity network (DNO) covers Dorset?
SSEN (Scottish & Southern Electricity Networks). We handle the full G98 (smaller systems) or G99 (batteries and larger arrays) connection application on your behalf.
Do you need planning permission for solar panels in Dorset?
Most installs are permitted development; conservation areas and listed buildings need sensitive design. The main planning authorities here include BCP Council (Bournemouth, Christchurch & Poole), Dorset Council. We advise per property and design discreet systems where required.
Which towns in Dorset do you cover?
We install across Dorset, including Bournemouth, Poole, Christchurch, Wimborne, Dorchester, Weymouth. If your town isn't listed, just ask — we very likely cover it.
Which grid operator (DNO) covers Dorset, and will I need a G99 application?
Dorset sits in the SSEN (Scottish & Southern Electricity Networks) distribution area. If your system is 3.68kW or smaller per phase and has no battery, it usually connects under G98 — SSEN is simply notified after we commission it. Larger systems, and anything with battery storage or export, need a G99 application approved by SSEN before installation. We prepare and file whichever applies to your BH or DT postcode as standard.
Do I need planning permission for solar panels in Dorset?
For most homes, no — domestic roof solar is normally Permitted Development as long as panels don't project more than 200mm and don't sit above the highest part of the roof. The exceptions matter locally: listed buildings need Listed Building Consent, and panels on a roof or wall fronting a highway within a conservation area may need a full application. Both BCP Council (Bournemouth, Christchurch & Poole) and Dorset Council have conservation areas and listed stock, so for heritage properties we design discreet all-black, rear-slope systems.
How much does a solar system cost in Dorset?
Our solar-only Basic package starts from £4,995, solar-plus-battery from £6,995, and a Tesla Powerwall 3 Premium system from £12,920 (a £375 Tesla rebate applies). Every price is a 'from' figure and subject to a survey of your roof, and includes bird protection mesh as standard. We give a clear written quote with no pushy sales.
Is Dorset actually sunny enough for solar to pay?
Yes — Dorset gets some of the highest sun-hours on the South Coast, around 1,090–1,120 kWh per kWp installed each year. A south-facing 4kW array here generates roughly 4,000–4,400 kWh a year; east or west roofs produce about 15–20% less but are still well worth it, especially paired with a battery and an SEG export tariff.

Choosing a Solar Panel Installer in Dorset: What Actually Matters

Dorset has no shortage of companies offering solar, so it helps to know what separates a serious installer from a van and a ladder. Start with MCS certification — it is the baseline standard your system needs to be signed off against, and export tariffs expect it. Then look at manufacturer accreditation: we are a Tesla Certified Installer, which relatively few firms on the South Coast hold, alongside Octopus Trusted Partner and TrustMark registration, with a 5.0 rating from 61 Google reviews. Finally, ask a simple question that catches out a lot of installers: who files the G99 application?

That question matters because of how grid connections work. A small system at or under 3.68kW per phase can go in under G98 — connect and notify. But anything with a battery or export capability needs G99 approval from the district network operator before installation, not after. The whole of Dorset sits on SSEN's network, covering the BH and DT postcode areas, and we file the G99 paperwork with SSEN on your behalf and wait for approval before we book your install. If an installer tells you the paperwork can be sorted out later, that is a warning sign.

Dorset's geography brings two practical considerations. Seafront and clifftop homes in Bournemouth, Poole, Sandbanks and Christchurch face salt-laden air, so we specify coastal-grade fixings on exposed properties — corrosion resistance is not a place to economise forty metres from the sea. Inland, the historic cores of towns like Dorchester and Wimborne carry conservation-area sensitivities, so it is worth checking your property's status before committing; we can talk that through at survey stage.

An honest note on distance: we work Dorset from our Portsmouth base — Bournemouth is around 38 miles, Poole around 40 — so we schedule Dorset surveys efficiently, grouping visits in the same area. Most installations are completed in a single day, so travel has little bearing on how your job runs.

You may also have seen Solar Together Dorset, the council-run group-buying scheme. It is a legitimate route and worth investigating. Our view is straightforward: get the Solar Together offer, then let us quote against it. We are happy to be compared on equipment, workmanship and the certifications behind the installation — if the group-buy deal genuinely beats us on a like-for-like system, you have lost nothing by checking.

Is solar actually worth it in Dorset?+

Yes — the South Coast is one of the better parts of the UK for solar, with irradiance of roughly 1,050–1,150 kWh per kWp per year. A 4kW south-facing system in Dorset typically generates around 3,900–4,600 kWh annually; east/west roofs produce about 15–20% less but still perform well, especially when paired with a battery.

Who is the electricity network operator in Dorset, and what is G99?+

All of Dorset is on SSEN's network. Systems at or under 3.68kW per phase can connect under G98 (install and notify), but any system with a battery or export needs G99 approval from SSEN before installation. We handle the G99 application and approval for you as part of the job.

Do you really cover Bournemouth and Poole from Portsmouth?+

Yes. Bournemouth is around 38 miles from our Portsmouth base and Poole around 40, and we schedule Dorset surveys efficiently by grouping visits. A typical installation is completed in a single day, so the distance makes no practical difference to your project.

How does getting a Dorset solar quote work?+

Get in touch and we'll book a survey, grouped with our other Dorset visits. We assess your roof, exposure (coastal properties may need upgraded fixings) and grid connection, then provide a written quotation — all pricing is from-prices subject to survey. If you have a Solar Together Dorset offer, bring it along and we'll quote against it like for like.
