Are you considering installing solar panels 
but wondering what the process entails? I'm Sue Angel from green match and in this video We cover the eight most important questions related to the solar panel installation process; from whether your home is suited for solar panels, the best roof direction, the installation process, and more By the end of it you'll know exactly what to expect and how to best 
prepare your home for solar panels. If you're interested in learning even more about solar panels we've placed relevant links to the articles in the description below so go ahead and check them out! And before we dive in please take a second to

Now let's get started Is my home suited for solar panels? Generally speaking most roofs in the uk can have solar panels mounted on them to be sure that yours can verify the following things: Your roof is large and sturdy enough It needs to have a big enough surface area to mount solar panels and it needs to be strong enough to hold the weight of them consider about one meter 
by 1.7 meter for each panel and measure if you have enough roof space for the number of panels you need you can get a structural report done by a professional to assess this if you're in doubt also ensure that your roof gets plenty of sunlight sunlight hours are very important because you want your solar panels to be exposed to sun for the majority of the day to generate plenty of electricity there should be minimal to 
no shade cast on your roof by neighbouring buildings or trees this brings us to our next point What's the best roof direction for solar panels? As a general rule of thumb if you 
live in the northern hemisphere you want your solar panels to be facing south this will produce the 
maximum amount of electricity from morning all the way through 
to the afternoon or early evening that being said there is an argument to be made that south facing may not be 
the best direction for everyone south facing panels will 
produce the most electricity in the middle of the day but if you're never home at that time you may be better off with 
east and west facing panels this way the panels will 
capture the early morning sun as well as the evening sun ultimately this depends on your household schedule so consider your routines and energy habits to make the best decision Do I need planning permissions 
to install solar panels? In England, Scotland and 
Wales, you're not required to apply for any planning permission for most domestic installations that being said, there are some 
restrictions for certain installations For example your solar panels may not protrude more than 20 centimeters from your roof otherwise you'll need to 
apply for permission first the roof needs to be able to bear the weight of the solar panels, if not, then 
strengthening work needs to be done before the installation can take place Also, if your building is 
within a conservation area you'll need to adhere to specific 
planning permission guidelines You should consult your 
local authority in this case.

What are the components in a solar panel system? There are four main components 
in a solar panel system 1. The panels
2. The inverter 3. The power meter 4. The battery if needed and the 
charge controller if you have batteries The panels are of course the 
components that produce the electricity all panels together make up 
what's known as the solar array The inverter is another crucial component because the panels produce direct 
current and we need an inverter to convert that electricity to alternate current which is what standard household appliances use The power meter is what measures 
how much electricity is generated This is required if you want to make 
use of solar panel funding schemes such as the Smart Export Guarantee With a battery, you can store 
the electricity produced by your panels and use it at night when the sun has gone down The charge controller regulates 
the proper charging voltage with a battery and avoids overcharging.

Overcharging damages the batteries 
and shortens their lifespan and can even produce safety risks so this is an important component. What is the solar panel installation process? The installation process for 
a domestic solar panel system shouldn't take longer than a day. Before the actual installation takes place, a professional installer will have 
already come and assessed your home determine the right system size and plan the layout of the actual installation. On the day of the installation the installers first need 
to set up the scaffolding and mark out the positioning of the solar array the way your panels are 
mounted depends on your roof.

Clay tiles are the most common in the UK so let's consider this roof type Once the installers have marked 
out where the array will be mounted the next step is to lift the 
tiles and find the rafters. The rafter line is where the roof 
hooks are mounted to ensure stability Once all roof hooks are secured to the rafters the tiles are put back in place. You don't need to worry about any 
leaks caused by drilling into the roof tiles are weathered if needed and 
professional installers follow strict measures to protect your home against any damage. Then the rails are bolted onto the roof hooks and finally, the panels themselves 
can be secured onto the rails. Once this step is complete the system needs to be wired and connected to the house the panels need to be connected to the inverter the power meter and the batteries and charge 
controller if you choose to install those too You should also consider pigeon 
proofing your solar panels to eliminate the issue of 
birds nesting underneath them This can be done by placing 
steel sheets around the array. Can I install solar panels myself? While you can install solar panels yourself it can be very time consuming and a technical process Some companies sell DIY kits 
with installation instructions but if you're not very technically savvy it can be overwhelming with all the components, wires and cables you risk damaging the system or your roof so it might not be worth doing it yourself.

Next, let's cover the installation 
cost if you hire a professional How much does it cost to 
install solar panels in the UK? The majority of the costs 
are based on the system size When considering installing solar panels you first need to know what system size you need For a 3 kW system, you will pay 
roughly 5,000 to 6,000 pounds for a 4 kW system, you can 
pay between 6 to 8,000 pounds a 5 kW system will set you 
back around 7 to 9,000 pounds and a 6 kW system costs around 8 to 10,000 pounds These prices are of course broad estimates and the final price ultimately 
depends on a number of factors It's always best to get an installer 
to give you an accurate quote for your specific home The prices mentioned include installation fees which is common when you're given 
a quote for a solar panel project Here's how the installation 
fees can be calculated.

On average it costs about 300 
to 500 pounds per person per day It usually takes about two people 
to carry out an installation so you're looking at 600 to 
1000 pounds in servicing fees If your solar array is bigger say 12 kWs then it can take up to three days so 
the cost can go up to 3 000 pounds Another way to calculate is to 
use 20 pence per watt fitted so if you have a 4 kW system you'll be paying 20 pence for 4 000 watts resulting in 800 pounds.

How do you maintain solar panels? Once you've installed your solar panels there isn't really much maintenance needed It's important that the panels are clean and that there's nothing blocking them from efficiently absorbing sunlight Remove any branches or leaves 
that might have landed on them. Before you clean the panels yourself consult your installer about 
the warranty conditions Some manufacturers have 
specific cleaning guidelines so be sure to adhere to this. Rainwater usually gets rid 
of most dirt on your panels but if you need to manually clean them it's best to do it contactless with a hose If you want to give them a more thorough cleaning it's usually safe to use dish soap and warm water Now, there are solar panels on the market that are considered to be self-cleaning This is because these panels 
are coated with a special film that makes dirt and grime glide right off. By now you should have a pretty clear picture of what the solar panel 
installation process entails but if there are any questions
