Solar energy is quickly becoming the go-to solution for UK homeowners looking to reduce energy bills, boost their property's value, and lower their carbon footprint. With over 1.6 million UK homes already benefiting from solar power, it's an ideal time to consider joining them.
This guide will clearly explain every step involved in the solar panel installation process, from initial assessment to system activation, ensuring you're well-informed throughout your solar journey.
8-Step Installation Process
Follow this comprehensive step-by-step guide to understand exactly what happens during your solar panel installation journey.
- Roof Orientation: South-facing roofs generate the most energy, but east or west-facing roofs also perform well.
- Roof Angle: Ideal angles are between 30-40°, but adjustments can be made for flat roofs.
- Shading: Trees, chimneys, or nearby buildings can affect energy production, so installers will suggest solutions if needed.
- Roof Condition: Your roof needs to be structurally sound to support panels safely.
- Electrical Setup: A brief check ensures compatibility with your existing electrical system.
- Energy Usage: Typically, a 4-5 kW system (around 10-14 panels) suits an average UK home.
- Available Roof Space: This determines how many panels can be installed.
- Type of System: You'll decide between standard string inverters or microinverters (which optimise each panel's output).
- Optional Battery Storage: Although not mandatory, adding batteries now or later allows you to store energy for night-time use.
- Most UK homes can install solar panels without needing planning permission under permitted development rights.
- Panels must not protrude significantly above the roof line.
- Homes in conservation areas or listed buildings may need special permission.
- Your installer will handle checks and paperwork, including compliance with Building Regulations.
- Select a certified installer through the Microgeneration Certification Scheme (MCS).
- MCS certification ensures quality work and consumer protection.
- Certification makes you eligible for financial incentives like the Smart Export Guarantee (SEG).
- Always verify credentials and check customer reviews before making a decision.
- Scaffolding will be erected around your home a few days before installation.
- This provides safe roof access for the installation team.
- The scaffolding typically remains for a short period after installation.
- Clear access paths and remove any fragile items from the work area.
- Installation typically takes just 1-2 days for most homes.
- Mounting Rails: Installers fix special brackets and rails onto your roof securely.
- Panel Placement: Panels are attached securely to these rails.
- Electrical Wiring: Panels are connected via cables running through your home to the inverter.
- Inverter Installation: The inverter converts solar-generated electricity into usable power.
- Grid Connection: Your system connects to your home's electrical panel.
- Thorough safety checks and system tests are conducted.
- Your system is registered with MCS for certification.
- You'll receive an MCS certificate required for incentive schemes.
- The installer demonstrates how your new system operates.
- Basic maintenance and monitoring procedures are explained.
- Once activated, your panels immediately start producing electricity.
- The Smart Export Guarantee (SEG) scheme pays you for surplus electricity sent back to the grid.
- You will need a smart meter and your MCS certificate to register.
- Rates vary by supplier, so it's beneficial to shop around for the best deal.
- Monitor your energy production and export through your inverter's app or display.
