What is the installation process?

We supply, install and test all of the equipment for your solar system and arrange the scaffolding. On completion we show you how to operate your new system, provide a manual of your installation and register you with the microgeneration certification scheme. We can also provide assistance with your electricity supplier and help register you for the Feed in Tariff scheme.  We can also assist with your Energy Performance Certificate.

What do I do?

You do not need to do anything. Our service is designed to provide minimum disruption to you.


What type of roof should the panels be fitted to?

Solar photovoltaic panels generate maximum efficiency from south facing installations which are not overshadowed by trees or buildings. If the surface is in shadow for parts of the day, your system will generate less energy.

Systems facing East or West are less efficient but still viable. Systems such as solar trackers maximise exposure to the sun by following its path and will increase efficiency by 20% during the winter and up to 50% during summer over static systems.

Energy Performance Certificate

An Energy Performance Certificate (EPC) with a Level D or above is required if you wish to receive the highest Feed in Tariff rate set by the Government.  We can assist you with your EPC.  Having a solar panel installation will increase your EPC level.

Will scaffold be required?

Yes scaffolding will be required for most installations.

Can I expect much disruption?

Our service is designed to provide the minimum amount of disruption possible to your home.

The internal electrical work takes about a day and the roof work takes one to two days, depending on how many panels you have. We always tidy up, remove and recycle all of our packaging and materials upon completion.

How much does it cost?

The cost of a solar PV system will depend on your budget requirements and the specification of the panels you require. We source the best photovoltaic panels and inverters to provide you with the highest return possible for your investment. You can typically expect a system to cost in the region of 8,000

Is there any maintenance and is cleaning required?

AES Ltd can provide a bi-annual maintenance service to ensure your installation is working to the highest efficient output. Solar panels come with a warranty of 25 years.

How can I connect my system to the grid?

Permission is required from the Distribution Network Operator (your electricity supplier).  The DNO in the UK have different policies when it comes to connecting PV systems to their networks, and so different rates will be paid for the exported electricity. AES Ltd can make the necessary arrangements for grid connection. You will be paid per kilowatt peak for exporting the electricity generated click here

Do I need planning permission?
You do not need planning permission for most domestic solar electricity systems - but you should check with your local planning officer, especially if your home is a listed building, or is in a conservation area or World Heritage Site.
Planning regulations have recently been relaxed when it comes to typical residential solar PV installations, such as those mounted on roofs and in ground mounted frames.  However, there are restrictions connected with the size and nature of the solar PV array, exceptions are also made for properties within conservation areas and for those properties with listed status.

This is not to say that systems that do not fall into the categories below cannot be built.  It simply means that planning permission will be required before work commences.

When considering mounting a solar PV array on the roof of a residential property, to not require planning permission beforehand the system designer must ensure that:
  • The solar PV array does not protude more than 200mm.
  • The solar PV array does not face onto or is visible from the highway if located within a conservation area or a world heritage site.

When considering mounting a solar PV array in a ground mounted frame that will serve a residential property, to not require planning permission beforehand the designer must ensure that:

  • The solar PV array is no more than 4m high
  • The solar PV array is installed more than 5m from the property boundary
  • The size of the solar PV array does not exceed 9m sq
  • The solar PV array does not face onto or is visible from the highway if located within a conservation area or a world heritage site.

The installation of solar technology is well understood and in general welcomed by local authorities.  In our experience a planning application with a considered, well designed and reasonably sized system is likely to be treated fairly.


Is AES accredited under the Microgeneration Certification Scheme?

Yes we are accredited to install solar photovoltaic systems. Our MCS certificate number is NIC 1404 which registers Alternative Energy Solutions Ltdon the NICEIC MCS Installer Scheme under Solar Photovoltaic. Please note you need to use an accredited installer to be able to register for feed in tariffs. All our installers are employed directly by us. We only sub-contract work for scaffolding.

Choosing your Solar PV installer and avoiding the rogue traders?

Ask to see a copy of the MCS certification, check the name and that they will be carrying out the installation.

Always try to deal directly with the company carrying out the installation.

Check the company has current insurance and warranty for both the electrical and installation work.

Get confirmation that the products being used for your solar panel installation are MCS accredited.

Cheap prices can usually mean that the company may be new, inexperienced, or using cheap products.


What is the financial return?

The return on your investment is so substantial that we have dedicated this link page to the Feed in Tariff financial return click here


How long will a solar system last?

The Feed in Tariff for solar PV are calculated for an economic lifetime of 25 years. The Department of Energy and Climate Change typically expect that panels will produce for at least that long. The warranty conditions for PV panels typically guarantee that panels can still produce at least 80% of their initial rated peak output after 25 years. The best way to ensure and extend the life and effectiveness of your PV system is by having it installed and maintained properly.

How big a solar energy system do I need?

The size of your solar PV system will depend on the size of your roof space and how much you are willing to invest. We provide a free survey and listen to you and your budget requirements. We will find the best photovoltaic panels and inverters to match your budget requirements and provide you with the highest return possible for your investment. You can typically expect a system to have paid for itself within 8-10 years.

What guarantees do we offer?

We can guarantee that in the first 10 years, we will investigate your installation free of charge. All our panels are accredited under the Microgeneration Certification Scheme and have passed the relevant UK and EU standard tests. All our panels are guaranteed by the manufacturer to at least 80% performance after 25 years and all inverters are guaranteed for 5 years

What happens if something goes wrong?

All the PV panels come with a 25 year performance warranty. In the unlikely event that you experience problems, the supplier should be on hand to investigate your problem and if necessary, arrange a visit to ensure that everything is working as it should be. The installation comes with a 10 year warranty so you can be sure your service will be of the highest standard.
