How are Solar Panels Installed: A Step-by-Step Guide

Solar Panels in field

Solar panels are becoming an increasingly popular method of powering homes and businesses. They harness the sun’s energy to generate electricity, reducing the reliance on traditional energy sources and reducing carbon emissions. But how are solar panels installed?

Installing solar panels can vary depending on the type of system being used and the property’s location. Generally, the installation process involves several key steps including assessing the site to determine the best location for the solar panels, mounting the solar panels, and finally connecting them to an inverter.

However, properly installing solar panels can be a complex process that requires specialised knowledge and expertise. It is important to work with a qualified installer who can ensure that the system is designed and installed correctly.

9-Step Guide for Installing Solar Panels

1. Assess your site

Choosing the right solar panel system is crucial for the efficiency and effectiveness of your solar panel installation. Several solar panel systems are available, including grid-tied, off-grid, and hybrid systems. The choice of solar panel system will depend on your energy needs, location, and budget.

2. Choose the right solar panel system

Choosing the right solar panel system is crucial for the efficiency and effectiveness of your solar panel installation. Several solar panel systems are available, including grid-tied, off-grid, and hybrid systems. The choice of solar panel system will depend on your energy needs, location, and budget.

3. Obtain the necessary permits

Depending on the work needing to be carried out, your solar panel design will need to be approved by your local authority to comply with local regulations. You may need to obtain permits for building, electrical, or zoning permits.

4. Prepare for the installation

Preparing for your solar panel installation involves ensuring your property is ready for your installation team. You must clear any debris or obstacles from the installation site and ensure the roof is in good condition.

5. Install the mounting hardware

Prior to installing the solar panels, you must secure the mounting hardware to the roof or ground, depending on your solar panel design. It is important to install the hardware correctly as this will support the weight of your solar panels and keep them in place.

6. Install the solar panels

Once the mounting hardware is secured, you can move on to installing the solar panels. Your installer will secure your solar panels to the mounting system and ensure they are perfectly in place before securing them in place.

7. Wiring the solar panels

Next, your installer will wire your solar panels to the inverter device. The inverter will be stored inside your house, usually in the loft for solar panel systems that are mounted to your roof and is responsible for converting the sun’s energy into electricity that will be used to power your home.
Correctly installing the inverter can take between 4 and 6 hours based on the size of your solar panel system.

8. Connect the inverter to the consumer unit

At this point, the inverter will be connected to a circuit breaker in your consumer unit (more commonly known as your fuse box). This will allow the sun-fuelled electricity to power your property.
Your solar panel installer may also connect a generation meter to your system to monitor the amount of electricity your solar panels are producing. Some inverters already have this feature built-in, so it’s important to check whether this step is necessary for your solar panel installation.

9. Test the solar panel system

Once your solar panel installation is complete, it’s important to test your system to ensure it is all working properly and safely. This typically only requires turning the power on and off to check the electrical connections and ensuring that your solar panel system is measuring the energy output correctly.

Do you need a battery with solar panels?

It is not necessary to have a battery storage system as part of your solar panel installation, however, it does have some benefits. Opting for a battery storage system allows you to any excess solar energy generated during the day and use it at night when there is no sunlight, which can help to reduce your energy bills. Batteries can also work as backup power in the event of an emergency or a power cut so your property is never without electricity. Battery storage systems can be expensive so it’s important to consider this in the planning portion of your solar panel installation.

What is the best direction for solar panels in the UK?

Ideally, solar panels should face South or South-West in the UK to get the most sunlight. As we have a relatively cloudy climate here in the UK, solar panels can generate a good amount of energy when faced in any direction, however.

The direction of your solar panels is less important than making sure that shade from trees or nearby buildings isn’t obstructing sunlight from your solar panels. A professional installer can help you determine the best direction and placement for your solar panels based on your location and energy needs.

Do solar panels need direct sunlight to work?

While solar panels work best when they receive direct sunlight, they can still generate a sufficient amount of electricity in cloudy weather or indirect sunlight to power your home. However, the efficiency of the solar panels and the amount of electricity produced may vary in these conditions.

Solar Panel Installation – next steps

Now you know the ins and outs of how to install a solar panel for your home, you should be confident in designing and planning which solar panels you want for your home.

Remember to choose the right solar panel system for your needs, obtain the necessary permits, and prepare your property for installation to ensure your solar panel installation goes as smoothly as possible.
