Estimated solar yield for North West

Based on a typical 4kW south-facing system at 35° pitch. Figures use conservative regional irradiance data from MCS.

How we calculate this

System size: 4 kWp

Regional irradiance: 840 kWh/kWp/yr

Annual generation: 4 × 840 = 3,360 kWh

Import rate used: 24p/kWh (standard flat tariff, Q2 2026)

SEG export rate used: 15p/kWh (best fixed rate, April 2026)

Without a battery

Typical self-consumption of 40% for a household home during the day.

Self-consumed (40%)
1,344 kWh
Exported to grid (60%)
2,016 kWh
Import saving (24p × 1,344 kWh)
£323
SEG export income (15p × 2,016 kWh)
£302
Total annual benefit
£625

With a battery

A home battery typically raises self-consumption to around 75%.

Self-consumed (75%)
2,520 kWh
Exported to grid (25%)
840 kWh
Import saving (24p × 2,520 kWh)
£605
SEG export income (15p × 840 kWh)
£126
Total annual benefit
£731

These are estimates based on regional averages. Actual yield depends on your roof orientation, pitch, shading, and specific panel technology. Rates used: 24p/kWh import (Ofgem Q2 2026 price cap standard tariff), 15p/kWh SEG export (best available fixed rate, April 2026).

Your Distribution Network Operator

Your DNO manages the local electricity network and must be notified before your solar system goes live.

DNO for North West

Electricity North West

G98 and G99 notifications

Systems up to 3.68 kW (single phase) can use the simpler G98 process — your installer notifies the DNO within 28 days of commissioning.

Systems larger than 3.68 kW, or on a three-phase supply, require G99 approval before installation begins. This can add several weeks to your timeline.

A good installer will handle DNO notifications as part of the installation process. Ask them to confirm this before you sign a contract.

Local grants and schemes in North West

There may be funding available to reduce the upfront cost of solar panels depending on your household income and energy rating.

England households may be eligible for the Warm Homes: Local Grant through their local authority. Greater Manchester Combined Authority has been active in area-based retrofit — check with your borough council for current availability.

Also worth exploring

  • ECO4— the government's main energy efficiency scheme for low-income and fuel-poor households, funded through energy supplier obligations. Eligibility is based on income and EPC rating.
  • 0% VAT on solar — solar panels, batteries, and installation are zero-rated for VAT until at least 2027, saving around 20% compared to other home improvements.
  • Smart Export Guarantee (SEG) — all licensed energy suppliers with 150,000+ customers must offer an export tariff. You earn money for every unit you send to the grid.

Planning permission in North West

Most UK solar installations fall under permitted development and do not require a planning application.

The Lake District National Park covers significant parts of Cumbria — properties within national park boundaries require full planning permission for solar installations. Urban properties in Greater Manchester and Lancashire typically qualify for permitted development.

Permitted development

Applies to most houses. Panels must not protrude more than 200mm from the roof surface and must not be higher than the highest point of the roof.

Conservation areas

Permitted development rights may be restricted. Panels visible from the road or public right of way may require prior approval from the local authority.

Listed buildings

Full listed building consent is almost always required before solar panels can be installed on a listed property. Seek advice from your local authority conservation officer.

Planning rules in the UK are set at national level but interpreted locally. Always confirm with your local planning authority if you are unsure.
