Solar Installation – A Step by Step Guide

The move towards renewable energy is growing, and solar panel installation is one of the most effective ways to reduce energy bills and cut carbon emissions. Whether you’re a homeowner looking to power your property sustainably or a business aiming to lower operational costs, understanding the installation process is vital.

This guide walks through each stage of solar panel installation, covering what to expect, how the system is set up, and key factors to consider before making the switch.

Step 1: Assessing Your Property’s Suitability

Before installation begins, an assessment is required to determine whether your property is suitable for solar panels. A professional installer will evaluate several key factors:

• Roof condition and structure – Solar panels need a stable and secure surface. If your roof is old or damaged, repairs may be necessary before installation.
• Orientation and angle – South-facing roofs in the UK receive the most sunlight, but east- and west-facing roofs can still generate efficient solar power.
• Shading concerns – Trees, chimneys, or nearby buildings can obstruct sunlight and reduce efficiency. Installers will assess potential obstructions and recommend solutions.

If your property isn’t suitable for rooftop panels, ground-mounted systems might be an alternative option.

Step 2: Planning and System Design

Once your property is deemed suitable, the next step is designing the solar panel system. This involves:

• Choosing the right system size – The number of panels you need depends on your energy consumption and available roof space.
• Selecting the best solar panels – Different panels offer varying efficiency levels. Monocrystalline panels tend to be the most efficient but come at a higher price.
• Inverter selection – The inverter converts solar energy into usable electricity. Installers may recommend string inverters or microinverters, depending on the setup.
• Battery storage options – If you want to store excess energy, a solar battery system can increase self-sufficiency and reduce reliance on the grid.

Once the system design is finalised, an installer will provide an overview of expected energy output and savings based on your location and roof conditions.

Step 3: Securing Permissions and Grants

In many cases, solar panel installation doesn’t require planning permission, but certain situations may need approval:

• If your property is in a conservation area or is a listed building
• If panels are being installed on flat roofs or ground-mounted systems in visible locations

Your installer can help you determine whether permission is required and assist with any applications.

Additionally, homeowners and businesses may be eligible for government incentives to reduce installation costs, such as:

• The Smart Export Guarantee (SEG) – Earn money by selling excess solar power back to the grid.
• Zero VAT on solar panels – The UK government has removed VAT on residential solar installations until 2027, reducing upfront costs.

Step 4: Installation of Solar Panels

The actual installation process typically takes one to three days, depending on system size and complexity.

Mounting the Panels

• Roof brackets are installed first to secure the solar PV panels in place. These brackets ensure the panels are angled correctly for maximum sun exposure.
• If installing a ground-mounted system, sturdy frames are built to hold the panels at the optimal tilt.

Wiring and Electrical Setup

• Solar panels are connected to the inverter, which converts DC electricity into usable AC power for your home or business.
• The inverter is usually installed near the fuse box, in a garage, loft, or utility room.

Battery Storage (If Installed)

• If you’ve opted for battery storage, the battery is connected to the system to store excess solar energy for later use.
• Popular options include the Tesla Powerwall and other lithium-ion storage solutions.

Once the wiring is complete, the system is tested to ensure all components function correctly before connecting it to the electrical supply.

Step 5: Connecting to the Grid and Testing

Once installed, the system needs to be approved and connected to the grid (if applicable). Your installer will handle this process, which involves:

• Final system testing to confirm everything is working efficiently
• Grid connection approval if you plan to sell excess electricity under the Smart Export Guarantee
• Energy performance assessment, which provides an estimate of how much energy your solar panels will generate

After these checks, your system is ready to generate renewable electricity.

Step 6: Monitoring and Maintenance

Once your solar panels are operational, regular monitoring ensures they continue working efficiently. Many systems come with an app or online portal to track electricity generation and usage in real time.

Maintenance requirements are minimal, but it’s recommended to:

• Clean the panels periodically to remove dust, dirt, or debris that could reduce efficiency
• Check for shading changes from growing trees or new buildings nearby
• Schedule an occasional professional inspection to ensure all electrical components remain in good condition

Most solar panel systems last 25-30 years, making them a long-term investment in renewable energy.
