Guild approved Solar PV installers
If you’re looking for reliable and competitively priced solar PV, the Renewable Energy Guild is here to help. We individually assess every member installation company to ensure that they meet our exceptionally high standards, and every solar PV client is issued with a Guild Certificate upon project sign-off.
The process takes just 5 easy steps (domestic installations only):
- Quotation – we’ll call you to assess your installation requirements and send you an accurate quotation by email. It takes 10 minutes and involves no salespeople.
- Structural survey – if you choose to proceed, we’ll arrange a convenient time for a structural engineer to visit you, in order to confirm that your roof is structurally sound and meets the relevant building regulations.
- Technical survey – upon receipt of your structural report and confirmation that you wish to go ahead, one of our qualified and experienced solar PV installers will arrange to visit and determine the precise location of the components to be installed.
- Booking and commissioning – upon booking, you’ll receive a unique job reference number and select your preferred time and date for the installation to start. The whole process will take 2-3 days and your electricity will only be off for around 1 hour, minimising any disruption.
- Sign off and certificate – on completion of your project, we’ll forward your Guild Installation Certificate and the paperwork required to claim your Feed-In Tariff and you’ll be asked to complete an online feedback form so that we can ensure you were satisfied with the standards of service provided by our approved and fully insured installer. All workmanship comes with a 10 year guarantee.

Solar panel installation – the benefits
The main benefits of solar installation are:
- Save money – solar PV will reduce your electricity costs
- Make money – get paid for generating the electricity you use via the Government’s Feed-In Tariff
- Sell the surplus – the grid will buy any excess energy that your installation has generated but has gone unused
- Help the planet – solar PV doesn’t produce by-products that can damage the environment, therefore reducing your carbon footprint
- Minimal maintenance – maintenance free except for an occasional light clean if necessary. Solar PV modules should be expected to last at least 20 years, as there are no moving parts – therefore, most modules have a 20 year performance guarantee. It’s important to note, however, that the lifespan of the inverters is approximately 7-10 years, so they will need changing at least once in the lifespan of the panels.
How do solar PV panels work?
Solar PV panels, are usually installed on the roof of domestic, industrial or commercial properties in order to generate electricity through sunlight. The energy produced can be used to run your appliances, and you don’t even need to worry about the UK’s reputation for bad weather – because they work even when the sun is hidden behind the clouds.
Your solar PV panels are wired up to a piece of equipment called an ‘inverter’ – this converts the electricity generated from a direct current (DC) into an alternating current (AC), enabling it to be used in your home as a power source.
Solar PV systems are connected to the electrics in your house, and as such, also connected to the National Grid – this allows unused, surplus electricity that has been generated by the system to be fed back to the grid. This also means that should your system be unable to provide a sufficient amount of power for your requirements, you can import what you need from the grid itself.
How much do solar panels cost?
The cost of installing a solar PV system on your home or commercial premises will vary depending on the size of the installation and also the quality of the core components used. The most common systems for residential properties range from 1KW to 5KW and will depend on the roof space available.
system prices and sizes are listed below:
- 1KW – Approximate roof space 08 sq m – Estimated Cost £2,500 – £3,000
- 2KW – Approximate roof space 15 sq m – Estimated Cost £3,000 – £4,000
- 3KW – Approximate roof space 21 sq m – Estimated Cost £4,000 – £6,000
- 4KW – Approximate roof space 28 sq m – Estimated Cost £6,000 – £8,000
- 5KW – Approximate roof space 32 sq m – Estimated Cost £7,000 – £9,000

What size system do I need?
Getting the right size solar panel system for your home or business is important, and understanding your energy consumption is a major factor. On average a family with two children will consume between 3,300KW and 4,500KW per year, so if the roof space is available we would recommend a 4KW to 5KW solar PV system. A 4KW installation should produce in the UK around 3,400KWh (kilowatt hours) per year and a 5KW system around 4,500KWh per year.
Is my roof right for solar?
There are a few factors to take into consideration that will determine if your property or business is right for a solar PV installation.
- Direction and the angle of your roof – A south facing roof with panels angled at 35-degree,s will optimise your systems performance. If the orientation of your roof is North facing this WILL reduce your systems performance and should be taken into consideration.
- Shading – Shading on your roof will effect your systems electricity performance and is important to take into consideration when planning your solar array.
- Roof strength – The average roofs in the UK are capable of taking the weight of a solar PV installation as they are structurally designed to take loads of around 100Kg per square meter. We would always recommend a structural report is carried out before any installation starts.
- Planning permission – Most homes in the UK do not need planning permission for the installation of solar panels. If your home is in a conservation area or a listed building you should contact your local council to check if planning permission is needed.
What are the different types of solar mounting systems?
- Rail mounted system – Solar PV modules are usually mounted on two horizontal mounting rails. The rails are attached to the roof by using roof hooks or other fasteners. The panels are attached to the rails using middle and end clamps.
- Integrated roof system – The tiles on your roof are removed and replaced by plastic plates. The plastic plates fit directly to the roof battens and are attached by fixings, After flashings are added to the mounting system solar panels are fitted directly to the inlayed mount.
- Solar tiles and slates -Solar tiles or slates integrate into your roof without any visible weatherproof or flashing, they are installed the same way as traditional roof tiles and blend in to the structure to give a more aesthetically pleasing look. Solar tiles are popular with homeowners and builders who are having new roof constructions.
- Flat roofs – Support structures are designed to achieve the right angle for your solar panel installation. Where there is a concern of breaching the integrity of the roof, support structures can be applied that use gravel or concrete to weigh them down avoiding any fixing holes.
You can install solar panels in many different areas of your property or premises from garages, car ports, or if you have the space a ground mounted system.
