Process & how-to

How are solar panels installed?

From survey to switch-on, and the paperwork that unlocks your export income.

The short answer

A solar install runs in clear stages: a site survey (roof, orientation, electrics), system design and quote, an install day (scaffold, mount panels, fit inverter and any battery, wire in and commission), then MCS certification and help to register for the Smart Export Guarantee. The physical install is usually 1–2 days; the survey and paperwork bracket it either side.

You won't be doing this yourself, but knowing the stages helps you check an installer is doing it properly — particularly the certification that protects your export income.

At a glance

The stages

  1. Survey: assess roof condition, orientation, shading and your consumer unit.
  2. Design & quote: system size, panel/inverter spec, battery option, generation estimate.
  3. Install: scaffold up, mount rails and panels, fit inverter and battery, wire in, commission and test.
  4. Certify: the installer issues an MCS certificate for the system.
  5. Export: register for an SEG tariff so you're paid for surplus power.
Don't skip the certificate: make sure your installer is MCS-certified and issues the MCS certificate. It's normally required to register for the Smart Export Guarantee, and you'll want it for any future sale of the property.

Do I need planning permission?

Most domestic roof-mounted solar is permitted development in the UK, but there are exceptions — listed buildings, conservation areas and some flat-roof or ground-mounted setups. A reputable installer will confirm the position for your property before work begins.

Frequently asked questions

How long does solar installation take?

The physical installation is usually one to two days for a typical home. The survey beforehand and the certification and export registration afterwards add a little either side.

Do I need planning permission for solar panels?

Most domestic roof-mounted solar is permitted development, but listed buildings, conservation areas and some flat-roof or ground installs can need permission. Your installer should confirm for your property.

What is MCS certification?

MCS is the quality scheme for small-scale renewables. An MCS certificate confirms a compliant install and is normally required to register for the Smart Export Guarantee.
