Solar panels in Ebbw Vale

Blaenau Gwent, the council area around Ebbw Vale, had 66,904 residents at the 2021 Census. Solar Cymru is an independent guide that refers home solar enquiries to MCS-certified installers. We are not an installer, lender or government service.

Ebbw Vale sits among hills, and that shapes the solar picture. This page explains how the terrain affects output and what the planning and grid steps involve. It also shows how to ask for quotes that suit a valley roof.

Hills, shade and what the figures mean

PVGIS gives about 930 kWh a year for each kWp on a south-facing roof at 35 degrees in Ebbw Vale. That sits below most Welsh towns, because the model reads shading from the surrounding hills. A 4 kWp system would therefore make about 3,700 kWh a year at that point. However, a roof on an open slope can do better, while one in a narrow valley can do worse.

Direction matters as much as the hills. East or west roofs make about 15 to 20% less than south, and north-facing roofs reach only 53 to 59% of south output. Our article on east-west and north-facing roofs shows when a split array still pays. Since shade changes through the day, ask each installer for a written shade factor.

Planning rules around Blaenau Gwent

Permitted development covers most house roofs in Wales. Panels may not stick out more than 200 mm from the roof slope, and they must not rise above the highest part of the roof. Flat roofs have their own limits, including a 1 metre gap from the roof edge.

Blaenau Gwent County Borough Council handles most questions, although part of the area lies inside Bannau Brycheiniog National Park. The National Park Authority plans that land. National parks do not appear in the Welsh domestic rules, yet the authority invites enquiries, so ask before you sign anything.

Cadw’s data records 2 conservation areas in the council area, with national park land recorded separately. A wall that fronts a highway in a conservation area is a different case. Check the council’s planning register too, because an Article 4 direction can remove permitted development rights. Our planning permission guide covers each exception.

Grid connection in the valleys

National Grid Electricity Distribution names Ebbw Vale in its South Wales licence area report, so it is your network operator. Most homes use the G98 route, which covers inverters up to 3.68 kW on a single phase. The installer then tells the operator within 28 days. Anything larger needs agreement first under G99, and the operator may ask you to contribute to network strengthening.

Spare power earns money through the Smart Export Guarantee. Suppliers set the rates, and Ofgem found an average near 4.4p per kWh on untied tariffs in 2024-25. Using the power yourself is worth more, because the Ofgem price cap for October to December 2026 averages about 26p per kWh. Our grid and export guide explains how to compare tariffs.

Costs, longevity and free schemes

Installers typically charge roughly £6,500 to £8,800 for a 4.5 kWp home system. VAT on home installations is 0% until 31 March 2027. Panels should last 25 years or more, although the inverter usually needs replacing after about 12 years. Read how long solar panels last before you judge payback.

Many people ask about free panels. Warm Homes Nest can include solar for eligible households that own or privately rent their home, receive a qualifying benefit or have a low income, and have a low energy rating. Solar is one possible measure, never a promise. Our article on free solar panels in Wales separates real schemes from sales claims, and the solar funding guide lists them.

Asking for quotes from Ebbw Vale installers

Send one enquiry through the quote form, and Solar Cymru refers it to MCS-certified installers. Our solar panel installation page explains the process and what each quote should contain. We do not fit panels, so the design, price and warranty come from the installer you choose.

Compare more than the price. Ask for the MCS performance estimate, the equipment names and the shade assumptions. If you live between towns, read the pages for installers around Merthyr Tydfil, solar quotes in Abergavenny and homes near Cwmbran.
