Curious about how to get started with solar panels and battery storage for your home? This article walks you through the installation process step by step, from initial planning to final setup. Learn what to expect at each stage, the timelines involved, and how to ensure a smooth, hassle-free experience.

Why installing solar panels is simpler than you think

Many homeowners are interested in solar energy but hesitate to take the plunge, often concerned about the complexity of the installation process. The reality, however, is that installing solar panels and battery storage systems is far more straightforward than it may seem. With the right planning, reputable installers, and a clear understanding of the steps involved, your transition to renewable energy can be smooth, hassle-free, and highly rewarding.

This guide breaks the process down into clear, manageable stages, so you know exactly what to expect at every step.

Step 1: Assessment of your home’s suitability for solar panels

Before installation begins, it’s essential to evaluate whether your home is suitable for solar panels. Factors like roof orientation, available space, and shading affect how much energy your panels can generate. South-facing roofs are ideal for maximum sunlight exposure, but east- or west-facing roofs can also provide excellent performance.

As professional solar installers, we will conduct a thorough assessment of your property, checking for:

  • Roof size and condition (to ensure it can support the panels).

  • Any nearby obstructions, such as trees or buildings, that may cause shading.

  • Your household’s energy consumption to determine the right system size.

At this stage, we will recommend a tailored solution, including the optimal number of panels, system size, and battery storage capacity for your needs.

Step 2: Planning your system, and securing approvals

Once your home has been assessed, the next step is planning the installation. This includes designing your solar system and obtaining any necessary permissions.

In the UK, most domestic solar panel installations do not require planning permission, provided they meet certain criteria:

  • Panels must not protrude more than 20cm above the roof surface.

  • Installations must not be visible from the road if your home is listed or in a conservation area.

We will handle these checks and ensure your system complies with building regulations. We will also help you apply for grid connection approval if needed, particularly when installing battery storage systems that feed electricity back to the grid.

Step 3: Selecting your solar panels and battery system

Choosing the right components for your solar system is critical to achieving the best performance and value. Your installer will guide you through options, including:

  • Solar panels – monocrystalline panels are often recommended for their high efficiency and compact size, especially when roof space is limited. 

  • Battery Storage – lithium-ion batteries are the most popular choice due to their long lifespan and reliability. They store excess energy during the day so you can use it at night or during peak demand. 

  • Inverters and monitoring tools – the inverter converts the solar energy into usable electricity, while monitoring tools allow you to track energy production and consumption in real time. By choosing high-quality components, you maximise your system’s efficiency and ensure a greater return on investment.

Step 4: Installation day

With all the planning complete, installation day marks the most exciting stage of the process. For most UK homes, the installation of a standard solar panel system takes 1-2 days, depending on the system size and complexity.

Here’s what to expect:

  • We will first mount the panels securely on your roof using a racking system.

  • Next, we will install the inverter and connect it to the panels and your home’s electrical system.

  • If you have opted for battery storage, the battery will be installed and integrated with your solar system.

  • Finally, the entire system will be tested to ensure it is functioning correctly and safely.


As professional installers we will also provide guidance on how the system works, so you feel confident using it from day one.

Step 5: Final checks and connection to the grid

Once the installation is complete, your solar system will undergo final checks and be officially connected to the grid. Your installer will:

  • Verify that all components meet safety standards and comply with regulations.

  • Register your system with the Smart Export Guarantee (SEG) scheme, enabling you to earn money for exporting unused energy back to the grid.

  • Provide you with system documentation, including warranties, performance details, and user instructions.

Step 6: Monitoring and maintaining your system

After installation, your solar panels and battery system require minimal maintenance to keep them running efficiently. Most systems include smart monitoring tools that allow you to track your energy production and usage from your phone or computer. This helps you identify opportunities to maximise your savings.

Occasional cleaning of the panels (to remove dust, debris, or bird droppings) and a professional check-up every few years will ensure your system operates at peak efficiency for its full lifespan.

Enjoy the benefits of solar energy

By following these simple steps, you can enjoy the many benefits of solar energy. A well-installed solar panel and battery system will reduce your reliance on the grid, lower your energy bills, and protect you against future price increases. Over time, you may well see a significant return on your investment, while contributing to a cleaner, greener environment.
