Home solar panel installation
Solar panels turn daylight into free electricity for your home, so you buy less from the grid. And with a battery, you can use that solar power in the evening too.
We design and install solar panel systems across Hampshire and the south of England, from £5,000 for a typical 4 kWp system. We install SunPower panels as standard, along with every other leading make available in the UK.
Why solar panels?
- Generate your own zero-cost electricity – from a free energy source: the sun
- From £5,000 installed – for a typical 4 kWp system, designed around your home
- Get paid for excess electricity you export to the grid – via the Smart Export Guarantee
- Significantly reduce your carbon footprint – save money and go green at the same time
- 0% VAT – on residential solar and battery installations until 31 March 2027

How much do solar panels cost?
The price depends on the size of the system, the panels you choose, your roof and whether you add a battery. As a guide:
- Solar panels from £5,000 – for a typical 4 kWp system, supplied and installed
- Battery storage from £4,200 – added at the same time or later on
- 0% VAT – on residential solar panel and battery installations until 31 March 2027 (read our update)
- Ground-mount systems – priced after we survey your land
We survey your home and energy use first, then give you a clear written quotation.
The solar panels we install
We can install all of the leading solar panels available in the UK, but the panel we quote as standard is SunPower. As a SunPower Elite Partner, the highest level of SunPower’s partner programme, we can offer the full range with its warranty fully honoured. The other panel we’re often asked about is Aiko.
SunPower – our recommended panel
- The panel we quote by default for most homes
- M Class – SunPower’s flagship panel, with a 40-year warranty on product, power and service
- Performance range – SunPower quality at a more accessible price, with a 30-year warranty
Aiko Neostar – a popular alternative
- All Back Contact (ABC) cells for a clean, all-black look
- 24.5% front-side efficiency from a shorter, lighter panel
- 30-year linear performance warranty
Shaded roof? We recommend SolarEdge power optimisers
On a standard system, shade on one or two panels (from a chimney, a tree or a neighbouring building) can drag down the output of the panels connected to them.
SolarEdge power optimisers fit behind each panel, so every panel works at its own best output, and the SolarEdge app shows you how each individual panel is performing.
We check for shading at every survey and recommend optimisers wherever they’ll make a real difference.

A 3-STAGE APPROACH AND UNRIVALLED SERVICE FROM START TO FINISH
We have an initial conversation with you on the phone to go through all of your requirements. It’s a chance for you to ask any questions you may have about solar panels, how they work, the benefits, and so on.
Next, we survey and then one of our Solar Designers recreates your property in our solar CAD software and builds a suitable solar panel / inverter combination.
Finally, we price your system up and send you a comprehensive proposal, including total cost, payback period, savings, income streams, all equipment supplied, warranties, and much more.
If you decide to go ahead, we complete the paperwork, and book an installation date.
On the first day of installation, our electrical engineers and roofers turn up early. Most home solar panel installations take just one day to put in, though this will usually extend to two days if you have battery storage as well.
Once the system is up and running, one of the engineers will explain how everything works, go through any relevant apps, etc.
After the installation, you will receive a final handover pack containing all the documents you need, including warranties.
Solar panel and battery systems fall into the ‘fit and forget’ category. They generally just work, day after day, with no human intervention required.
However, if something were to go wrong, you need maintenance support, or if you have any questions, we are always on hand to help out. Just give us a call on 0800 909 8882.
We also have a handy Solar Panels FAQ section if you need quick answers to common questions, plus you can learn about advanced SolarEdge monitoring if you have shading.

Solar panel FAQs
How much do solar panels cost?
A typical 4 kWp solar panel system is supplied and installed from £5,000. The final price depends on the size of the system, the panels you choose and your roof. Residential solar panel and battery installations are zero-rated for VAT until 31 March 2027.
Which solar panels do you recommend?
We recommend SunPower panels and quote them as standard. As a SunPower Elite Partner, we install the full range, including the M Class with its 40-year warranty covering product, power and service. We also install Aiko and all the other leading panels available in the UK. See our Aiko vs SunPower comparison for more.
What if my roof is partly shaded?
We check for shading at every survey. Where shade from a chimney, tree or nearby building would hold your system back, we recommend SolarEdge power optimisers, which let each panel work at its own best output. Our SolarEdge guide explains more.
How long does installation take?
Most home solar panel installations take just one day. We’ll give you a timescale for your own system when we quote.
Do I need planning permission for solar panels?
In most cases, no. Solar panels on a house are usually permitted development. There are exceptions, such as listed buildings and some homes in conservation areas, and we check this at your survey. Our guide to planning permission for solar panels explains the rules.
Can I add a battery to my solar panels?
Yes. You can add battery storage at the same time as your solar panels or later on, and battery storage is installed from £4,200. See our battery storage page for the options.
Can I get paid for the electricity I export?
Yes. Under the Smart Export Guarantee, energy suppliers pay you for the solar electricity you send to the grid. Rates and terms vary by supplier, and we can talk you through the options.
Do you install ground-mounted solar panels?
Yes. If you have land available, a ground-mount system can be a great alternative to a roof installation. See our ground-mounted solar case study.
