How do solar panels work?

Solar panels let you generate your own clean, renewable energy by converting sunlight into electricity for your home. The inverter transforms the solar energy captured by the panels into usable power, helping to cut your reliance on the grid and lower your energy bills. Surplus energy can be sold back through the Smart Export Guarantee (SEG) tariff, giving you a return on what you produce, and solar batteries store excess power to help you save even more, and enjoy greater energy independence day and night.

How much does a solar panel installation cost?

As part of your free quote, you’ll get a clear breakdown of the costs and estimated annual savings of your solar panel installation. The exact figure will depend on your roof size and energy use, but every quote includes installation, certification, and warranties – no hidden fees or unwanted surprises. 

What are the typical system sizes and savings?

A standard residential solar panel system in the UK is around 3.5kWp. That means, depending on your usage and local sunlight hours, you could cut your annual electricity bills by several hundred pounds. Save even more with solar battery storage to store unused energy for later use. 

How does the Smart Export Guarantee work?

Once your solar panel installation is complete, you can earn money back by exporting unused electricity to the grid through the Smart Export Guarantee (SEG). If this is something you’re interested in, we’ll help you register for SEG and explain how the export rates work in line with official Ofgem SEG guidance. Typical payback periods depend on your system’s size, usage, and tariff choice.

Do you need planning permission for solar panels?

For most UK homes, planning permission isn’t needed for solar panel installations as they fall under ‘Permitted Development’. There are a few exceptions to this, like listed buildings or buildings in conservation areas.

We work in line with official guidance from the Planning Portal, so all of our domestic solar panel installations meet current building and electrical safety standards.

Is your home suitable for solar panels?

The majority of homes in the UK are well-suited to solar PV installations. If you’re unsure, our expert team will confirm during your free remote assessment. To make sure every one of our installations performs efficiently and safely, we follow guidelines set out by trusted bodies, like Energy Saving Trust. Here’s what we look at:

Do you need planning permission?

In most cases, solar panel fitting for houses doesn’t require planning permission. We’ll confirm details for your property and use the Planning Portal to manage all building compliance on your behalf.

Where does your roof face?

South-facing roofs get the most exposure to sunlight during the day, which gives them the best results. However, east- or west-facing installations still deliver strong performance, so don’t be put off if your roof isn’t south-facing. 

How much shade is there?

Our solar panel installers will assess any shading from nearby trees or buildings and measure the available roof space to design a system that captures as much sunlight as possible throughout the day.

What condition is your roof in?

Solar panels can only be installed on safe, structurally sound roofs, so if any maintenance is needed, our team will advise before installation.

How much energy do you use?

Your current energy use habits will help us suggest the best system size (plus potential solar battery storage). This means your quote will be unique to you and deliver the best possible savings over its lifetime.

Solar panel installation FAQs

Have questions about solar panel installations? Here are the answers to some of the most common ones. If you can’t find what you need, just give our team a call.

Do I need planning permission for home solar panel installation in the UK?

In most cases, domestic solar panel installation in the UK doesn’t require planning permission. Solar panels are generally classed as Permitted Development, provided they meet standard size and placement rules. Exceptions only apply to listed buildings, conservation areas, and some flat roofs. 

How long does a residential solar panel installation take?

A typical residential solar panel installation takes 1–3 days, depending on your roof size and system complexity. The full process – from initial survey to grid connection – can take up to 45 working days if DNO approval is required. Your installer will provide a clear timeline as part of your final quote. 

Will solar panels work on my UK roof if it faces east or west (or is partially shaded)?

Yes, while south-facing roofs generate the highest output, east- and west-facing solar panels still perform well in UK conditions. During your free survey, we’ll assess your roof’s orientation, pitch, and shading to design the most effective system. 

What is the Smart Export Guarantee (SEG) and how does it affect me?

The Smart Export Guarantee is a government-backed scheme that allows homeowners to earn money by exporting unused solar energy back to the grid. Once your system is MCS-certified, you can register with a licensed energy supplier that offers SEG payments. Rates vary by provider, but the SEG helps you offset your electricity costs and reduces how long it takes for your solar system to pay for itself. 

How much do solar panels cost for a typical UK home, and what is the payback period?

The average solar panel installation in the UK costs about £6,000, though this varies depending on a number of factors, like the size of your roof. The payback period is typically between 6 and 10 years, depending on how much energy you use, where you live, and any SEG export earnings. 

What maintenance do solar panels require on a house in the UK?

Solar PV systems require very little maintenance. Panels should be kept free from dirt and debris to keep up their performance – a professional cleaning every year or two should do the job. All electrical components, like inverters, should be checked every 2–3 years.

How many solar panels will I need for my home?

The number of solar panels you’ll need depends on how much energy you use at home, as well as your roof space and orientation. During your initial survey, we’ll design a custom solar PV system to match your home’s layout for the best result.
