Manchester solar FAQs: sixteen plain answers

As many as the best slope holds, within the budget, rather than a fixed number. With 400-watt panels, eight panels make 3.2 kW, which on a south-facing Manchester roof at 35° would generate about 2,835 kWh a year, using PVGIS figures.

Yes, at a lower rate. Panels respond to daylight, and bright cloud still lets a good share through. The yearly PVGIS figures for Manchester are built from satellite records of the city's actual sky, so cloudy days are already counted in them.

While snow covers them, yes. On a pitched roof it usually slides off within a day or two as the glass warms. Do not climb onto the roof to clear it: a few lost winter days make little difference to the yearly total.

The Energy Saving Trust says 25 years or more, with the inverter, the box that converts the power for the house, usually needing replacement after around 12 years. Budget for one inverter replacement over the life of the panels.

Rarely. Rain rinses most dust and pollen away, and Manchester has plenty of it. Bird droppings or moss on a low-pitched roof are the exceptions. Use a specialist or a long-reach brush from the ground, never a pressure washer, and do not walk on the panels.

They can, and city pigeons often try. The gap between panels and roof is sheltered and warm. Mesh fitted round the edge of the array keeps them out and is easiest to add at installation; ask for it to be priced in the quote.

They should be declared to your insurer, as with any alteration. Many policies cover them as part of the building; some ask for the MCS certificate. Check before the installation date rather than after.

There is no reliable Manchester figure. A buyer will look at the generation record, the age of the system and its paperwork. Keep the MCS certificate, the electrical certificates and the warranties together, because a buyer's solicitor will ask for them.

Up to 16 amps per phase of inverter output, which is 3.68 kW on the single-phase supply most homes have. SP Electricity North West is notified after connection under G98. Above that, the installer applies first under G99.

Usually scaffold one day, panels and wiring over one or two days, and scaffold down later. If the scaffold stands on the pavement, Manchester City Council needs a permit, which runs for at least 28 days.

You can fit a compliant plug-in panel yourself. A roof system wired into your home is electrical work under the Building Regulations, and you need an MCS-certified installation to receive export payments, so in practice a roof system needs an installer.

They stay with the house and are normally included in the sale. Transfer the export payment arrangement and any warranties to the buyer, and hand over the paperwork. If the system was bought with a loan, check what the agreement says about selling.

Less than for someone at home in the day, because more of the output is exported instead of used. A battery or an export tariff changes the balance. Set your roof's output from our explorer against your own meter readings before deciding.

The main help is GMCA's Warm Homes: Local Grant, for eligible lower-income households across Greater Manchester, with rules including an EPC of D to G for owners and routes such as income below £36,000. We found no current council-run group-buy for solar when we checked on 3 November 2026.

In 2025/26 the government's figures give an average of £2,021 per kW for systems up to 4 kW and £1,768 per kW from 4 to 10 kW, for MCS-certified installations in the North West. VAT on installed solar is 0% until 31 March 2027.

The council's climate plan aims for a zero-carbon city by 2038 and says the city needs almost 400 megawatts of solar by 2030, alongside 78,850 retrofitted homes. Rooftops on homes, schools and businesses are part of that.
