Solar panels in Manchester: what to know before you buy

Output you can expect in Manchester

Manchester gets less sun than the south coast, yet solar still works here. The European Commission’s PVGIS tool models about 896 kWh a year for each kWp on a south-facing roof tilted at 35 degrees. Its Manchester calculation uses a standard 14% system loss.

Tilt barely changes the result. The best angle is about 40 degrees, and it models at 898 kWh per kWp, only two more than at 35 degrees. Therefore you do not need to fuss over the exact pitch.

Take a 5 kWp system as an example. Five times 896 gives about 4,480 kWh a year. That is nearly twice what Ofgem counts as typical yearly use for a medium home, which is 2,500 kWh. Treat the figure as a modelled estimate, because real output depends on your roof and on each year’s weather.

Shade and direction are the bigger levers. A south roof gives the best result, while east and west roofs give less. Tall neighbours, trees and chimneys can cut output too, so ask your surveyor to check shade at different times of day. Also tell them about any plans for an electric car or heat pump, because extra daytime demand changes the best system size.

Terraces, flats and shared roofs

Many Manchester homes are terraces or flats. That affects the job in practical ways. For example, roof space is limited, and a party wall may mean talking to a neighbour.

Our post on solar panels for terraced houses and flats covers roof space, leasehold consent and shared roofs. If you rent or lease, you will need the owner’s agreement before anything goes up.

Connecting to the grid

The network operator here is SP Electricity North West. Every home system needs to be reported to it. Because systems differ, the route depends on size.

MCS says that systems up to 16 A per phase follow G98, and those above follow G99. The count adds up all generators. Our guide to G98 and G99 grid connection explains what each route involves.

In practice, the installer makes the application or notification. The MCS standard puts that duty on the contractor. Still, ask for proof that it was done.

Planning in Manchester

Manchester City Council is the planning authority. For many houses, panels have not needed a planning application. However, England changed its rules on 27 August 2026.

The new rules split houses from blocks of flats, as the Planning Portal explains. Stand-alone solar on a block of flats can now need prior approval from the council. Older rules stay usable for eligible projects until 26 August 2027.

However, if you live in a conservation area or a listed building, expect extra checks. The same goes for flats. Ask the council before you pay a deposit, and keep its reply in writing.

Selling spare power

Power you do not use can go back to the grid. Under the Smart Export Guarantee, suppliers with at least 150,000 domestic customers must offer a tariff, but each sets its own rate. Rates therefore vary, so compare them. You also need a meter that gives half-hourly export readings, which is usually a smart meter.

Help with costs

Check what is available before you sign. VAT on solar and batteries is 0% until 31 March 2027, according to HMRC. It returns to 5% after that date.

Some low-income households may also qualify for England’s Warm Homes: Local Grant, which includes solar PV. Eligibility depends on income, EPC rating and who owns the home.

How to pick an installer

Use the MCS installer search to confirm a firm’s certificate. MCS certification is also what lets you claim export payments from your supplier. As a result, you lose that route without it.

Look for membership of the Renewable Energy Consumer Code too, because it adds protection. RECC members must insure deposits and workmanship warranties. That cover matters if a firm closes.

Gather three written quotes, because prices and scope vary, and compare them line by line. Ask what each price covers, from scaffolding to the grid paperwork. Our guide to solar panel installation lists the usual steps. The solar panel costs guide shows official price data.

Liverpool is the nearest large city west of here. See our page for solar installers serving Liverpool to compare output and network operators.

When you are ready, you can compare quotes from MCS installers. Your details only go on with your consent.
