Options

It is important that wherever you intend to place your panels is south, south-east or south-west facing and unshaded by trees or other houses, with full sun exposure from 10am – 4pm at least. You can install your panels on your roof, on a wall or on the ground. You can fix the panels onto a frame if you’re installing them on the ground or a flat roof or if you want to adjust the angle of the panels to receive better sun exposure. The panels should ideally be angled at a 30 degree angle of incidence.

Each panel measures around 1.5m2, with an average system taking up between 6 and 20m2. Some panels can be fitted flush with your roofing tiles to be more aesthetically pleasing, but these do cost a little more. The solar panels produced today are designed for this use, and will give the same waterproof covering to your home as normal tiles. You can also install solar tiles, which are solar panels the size and shape of roof tiles which can be fitted in place of normal roof tiles. Again, these are more expensive and less efficient but are an option if there are strict planning restrictions in your area. They can be used to repair your roof, which could offset the cost of the tiles a little.

Requirements

You will need to ensure the following:

  1. You have a metered electricity supply.
  2. You have access to your roof.
  3. Ideally you should have freehold of your property – If you have leasehold, you’ll need permission from the freeholder, or if you rent your property, you’ll need agreement from the landlord.
  4. If your home is a listed building, or in a conservation area you might need planning permission. Most homes don’t need planning permission for solar technology systems unless the panels protrude more than 20cm from the roof, but do check with your local planning officer, especially if your building is listed, or is in a conservation area or World Heritage Site.
  5. Check with your installer that the panels will not damage the integrity of your roof and that your roof is strong enough to bear the weight of the panels, as they can be heavy.
  6. Most insurers cover solar PV installations, however you should double check with your provider.
  7. If you are intending to apply for the FIT, it’s a good idea to check that your energy supplier is a FIT provider as they will be paying you the FIT.

3 days to install

Your installer will ensure that the panels are installed on your roof in the best arrangement to optimise electricity generation. The installer will also fit the inverter and make the connection to the Grid. A good solar PV array system will maximize the peak hours of sunlight, being angled so that the hottest, brightest part of the day will fall as fully upon the solar panels as possible.

FAQs

Will solar PV give me electricity during mains power cuts?
For the safety of electrical workmen, standard solar PV systems are shut off during power cuts. You can request a system that automatically disconnects your home from the grid during a power cut and provides power from the panels and a battery back up in your home during power cuts.
Are there any grants available for installing solar PV panels?
The Feed in Tariff is a payback scheme rather than a grant scheme, and has replaced most grants for solar PV systems however, grants may be available from your local council - please contact them for details. The Feed-In Tariff pays you for the electricity you generate using your PV system, as well as any excess electricity generated, which you can export back to the Grid.
Are solar PV systems a lot cheaper now?
The cost of the PV cells and associated equipment is driven by international supply and demand. Prices of these components have fallen substantially over the past few years as larger manufacturing facilities have been set up in response to strong demand particularly in Germany and Japan. Installation prices have in turn fallen as a result of the reduction in system prices and as the industry has grown. This drop in prices is set to continue.
How are solar PV panels fixed to the roof?
This will depend on the roof, but typically solar PV panels are fixed using rigid stainless steel brackets that are fixed directly to your roof rafters. The brackets hook out from underneath your existing tiles. Tiles or slates should not be drilled to fit the panels, nor should mastic/silicone be used to weatherproof your roof. Solar panels can be fitted to any roof type except thatched roofs.
How much do the solar PV panels weigh?
Solar PV panels typically weigh about 13kg per m2.
