A guide to solar panels

If you’re considering solar panels, you’ll want to know how much you’ll pay and how much you’ll save. Installing solar panels is far easier than you might imagine. You may start using solar electricity as soon as they’re installed! We’re here to assist you in learning everything there is to know regarding price and installation.

What are the costs of solar panels?

A solar panel system costs around *£6,200 (including installation).

You can save between *£85 and *£220 per year with a four-kWp system.

Solar panels will lower your energy expenditures.

What are the benefits of solar energy?

Solar energy is growing in popularity in the United Kingdom, and it is becoming more affordable and accessible than ever before.

People like you are seeking more methods to save energy and protect the environment by using renewable energy sources.

The numerous benefits of Solar Panels

Renewable source

Because of the consistent quantity of sun that the earth receives, solar energy is one of the most effective sources of renewable energy. Solar will continue to be harnessed in better, easier, and less expensive ways as new technologies emerge, making it the fastest-growing renewable energy source.

Clean technology

Solar PV (photovoltaic) panels have a low carbon footprint, and their carbon footprint is shrinking as the materials used in them are more recycled.

Money saving

Because you’re generating and using your own energy rather than buying it from your supplier, your electricity bills could drop significantly.

No permit required

Solar panels are normally not required a permit  to be installed on your roof because they are considered “permitted development.” There are a few constraints to be aware of before installation.

Little maintenance

Solar panels require very minimal upkeep once they are installed. They are typically installed at an angle to allow rainwater to freely run off, cleaning dirt and dust away. Solar panels can last for more than 25 years with little loss of efficiency if they are not obstructed by dirt.

Less reliant

You will be less reliant on the National Grid for your electricity if you invest in a solar power system. As an energy generator, you can save money on electricity all day. And if you invest in battery storage, you could carry on using solar energy after the sun goes down.


You’ll be helping to make energy generation more efficient. Energy loss is unavoidable when energy is transmitted from power plants to your home over large networks. When your power comes directly from your rooftop, there are fewer losses, which means less energy is squandered.

Generate energy after dark

You may be utilising your own electricity all day and night if you invest in a home solar battery storage system.

Increase your property value

Solar panels are a fantastic investment for your home in general. According to current energy market trends, a home with solar panels could command a greater price in the future than one without (if appropriately marketed with a focus on fuel savings and tariff payments).

What is solar electricity?

Solar energy involves the use of the sun’s free energy to provide electricity using solar photovoltaic panels (PV). Solar PV requires only daylight and not direct sunlight to generate electricity. As such, power can be generated even on a cloudy day.

What is a solar photovoltaic panel?

Solar photovoltaic systems comprise two main components

Solar collectors 

Which collects the sun’s rays so that when light shines on the cell it creates an electric field causing electricity to flow.


This includes a converter to convert the direct current electricity from the panel to alternating current so it can be connected to the building’s main electricity distribution board.

Additional information about Solar Panels

Technology Type – There are many types of solar PV panels with different characteristics (crystalline cells, thin-film, hybrid). They consist of one or two layers of semi-conducting material, normally packaged together into panels or other modular forms.

Size – Small scale installations can vary from 0.5m2 to 1m2. They can be connected together to form an array that can cover a few m2 to hundreds of square meters. A typical small-scale array would have an area of 9 to 18m2.

Location – Solar collectors are usually placed on the roof of a building, but can also be wall-mounted or stand-alone (free standing) structures. PV systems can also be found in a roof tile form and can be mounted vertically and horizontally to form part of the building structure.

Performance – For best performance, solar collectors will need to face between southeast and southwest and be of the shade of trees and buildings. East or west installations can also provide good performance and can be used for a building with a roof or wall that faces within 90 degrees of south.

Weight – The roof where the solar collector is to be installed should be strong enough to support the weight and prevent any safety issues from arising.

Maintenance – PV panels are considered to have low maintenance if they are installed correctly.

Grid connection – Electrical grid connection requires approval from the distribution network operator (DNO).

What planning issues should I be aware of when considering installing Solar Panels?

There are economic, social and environmental impacts that should be considered when installing solar PV. Some of these impacts arise during the installation and construction phases, and there are a number of ways in which the design, location, and installation of solar PV can minimise these impacts.

Solar Panels Checklist

The checklist below provides some of these impacts and ways in which you can minimise them.

Frequently Asked Questions

Is my home suitable for solar panel installation?

Whether your roof faces south, east, or west your home is perfect to have solar photovoltaic panels installed. North facing roofs will not receive as much sunlight and therefore won’t be as efficient. The pitch of your roof should be between 10 – 60 degrees,

Do I need to get planning permission to get solar panels installed?

Having solar panels installed in your home is classed as a “permitted development”. You only require planning permission if you live in a listed building or area of outstanding natural beauty.

Can I put up my own scaffolding?

In most circumstances we will insist on putting up our own scaffold, to ensure the safety of you and our solar panel installers, however there are exceptions when scaffold is already in place for renovation works or a new build home is being built, but that scaffold would have to meet with our safety standards.

How long does it take from consultation to install?

Our lead time from consultation to solar panel installation is around 4-6 weeks, unless you need an application to your local network – then it can take a little bit longer.
