How long does it take to install solar panels?
Always search for a Microgeneration Certification Scheme (MCS) approved company to install your solar panels, as they are professionally qualified to take care of the whole process.
For residential properties, the actual installation of the solar panels should only take one day for average sized panels. However, installation may take up to two days for panels which are slightly bigger – but still suitable for residential purposes.
You should always request at least three quotes from registered MCS companies, and these quotes should include how long the installation will take.
If a company is predicting that the work will take more than one or two days, it is an indication that they may be overcharging for labour, and you should consider choosing another company.

Solar panel installation process
Find an installer
The first step in the solar panel installation process is finding a MCS approved company to install your solar panels. MCS is a certification scheme supported by the Department of Energy and Climate Change (DECC), ensuring that manufacturers and installers of green technology are held to the highest possible standards.
It is very important to find an installer who is MCS accredited, otherwise you will have no quality guarantee.
You can find MCS approved installation companies through the MCS website. Alternatively, you can use the form at the top of the page to find MCS approved installers in your local area.
Get a quote
Once you have found MCS approved solar panel installers in your area, you will need to get a quote for their services.
It is recommended that you get three quotes to compare the price and quality of service offered. Legitimate companies will never offer you a quote over the phone, as your house must be assessed in person to determine whether your roof is suitable for solar panel installation.
Professional companies will most likely send a team including a qualified surveyor (to carry out the assessment) and a salesperson (to advise on the service they offer).
A company should never try to pressure you into signing with them or offer you discounts for same-day installation. Instead, each company should leave you with a house assessment detailing the suitability of your roof and a quote for their work.
You should then take some time to look over the quotes, and decide which company is best for you.
On the installation day, you will not have to prepare your home or your roof in any way. The installers will set up a scaffold to access the roof and they will take it down again at the end of the day, or on the next day if it is a particularly big installation.
The installation involves three main stages:
1. Fitting the frame for the solar panels
2. Installing the panels
3. Connecting the panels to the inverter
The inverter is the machine that converts the light from the sun into usable electricity for your household appliances, and it is usually kept in the attic space.
Installers should also check your system before they leave to ensure that everything is working correctly.
Solar panel companies should not charge separately for installation.
The installation costs are absorbed into the overall quote for your solar panels. This quote should cover everything, including the solar panels, the labour, the scaffolding, and any supporting documents needed.
The quote you are given should include a breakdown of costs to show where your money is being spent. If you are given a quote with a single figure and no details, you should ask for a breakdown of the costs.

Finding an installer
It is very important that you find an MCS-approved company to install your solar panels. Using an MCS approved company can give you peace of mind, and also allows you to qualify for the Smart Export Guarantee (SEG), which pays homeowners for exporting clean energy back to the grid.
