Solar Panel Installation
Getting solar panels installed is a lot easier than it may seem. With the right installer accredited by the Microgeneration Certification Scheme (MCS), you will be able to ensure that you get the right solution for your home.
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.
You will need to ensure the following:
- You have a metered electricity supply.
- You have access to your roof.
- 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.
- 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.
- 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.
- Most insurers cover solar PV installations, however you should double check with your provider.
- 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.
We will only put you in touch with installers that are MCS accredited: Always use an MCS accredited installer. Only MCS accredited installers are able to sign off installations that will comply with the government’s Feed-In Tariff scheme.
- What is a kWh?
- A kWh is a was to measure electricity, particularly electricity that is generated by your renewable energy system. A kWh or 'kilo watt hour' is often referred to as a unit of electricity that is shown on your electricity bill. If an electrical product has a rating of 1 kW it means that it will consume 1 kWh every hour that it is on.
- Do solar PV installation prices include the price of scaffolding?
- Some PV installers do not include the cost of installing the necessary scaffold at your property when quoting costs. Make sure that you check this when comparing quotes from various installers.
- Are solar PV panels fragile?
- Solar PV panels are very robust; they are designed to withstand the normal stresses and strains subjected to them by nature. You can ensure that your panels are robust by purchasing only MCS accredited panels.
- Can I heat water with solar PV panels?
- Whilst PV panels do not directly heat water (this is what solar thermal panels do) they do produce electricity that can be used to do anything that you want to - even export it back to the grid for an extra payment. This electricity can be used to heat water if you have an immersion water heater.
- Will solar PV panels affect my home's rateable value?
- Council tax is based on the 1991 values and the government shelved plans to revalue all houses a few years ago, so currently, no. It is likely that there will be a revaluation in the not so distant future. When they do, the value of the solar panels will be included in the valuation, but the rating could also account for your home's the Energy Performance Certificate (EPC) which should reduce tax as you would have a lower EPC score.
