Solar PV Installations

Solar panels are a simple reliable technology that take the sun’s energy and turn it into electricity.

With solar panels if you’re making more energy than your house needs, you are self sufficient and won’t draw any power from the grid. The excess produced energy is what charges up a solar battery. Once the sun goes down and the solar panels can’t provide power, the battery kicks in and continues to keep you independent until it drains.

Create your own power and reduce your reliance on the grid

Consume more clean power rather than gas/coal/nuclear generated

Get paid for any power exported to the grid

Charge electric vehicles for free

Domestic Solar PV has been popular since 2010 across the UK and is a super cost effective way of reducing your energy consumption and bills.

They produce clean renewable power which helps reduce your carbon footprint significantly. If you export power to the national grid, you can get paid for this!

Over a million properties across the UK have solar panels installed and is it any wonder why? Years of production with next to no maintenance, just trouble free bill reduction. 

Add value to your home and increase the EPC/efficiency all whilst helping save the planet.

Choose from some of our more popular packages, or get in touch to have a system designed bespoke for your home.

Our Process

We like everything to be simple and easy, from beginning to end.


Initial Consultation

Speak with a member of the team and one of our solar energy experts will discuss your enquiry in detail to provide you with a solution tailored to your property. We have technology to measure a roof space from Google earth images and can provide a quote from this.


Receive Quote

Cahill Renewables will provide a proposal & quote for the installation having taken measurements remotely. The proposal includes roof modelling, a quote and projections. We do not send sales reps to properties.


Make DNO Application

After agreeing with the quote, we need to make an application to the district network operator (national grid) to install the solar system. This usually takes up to 7 days depending on the DNO in your area and is handled by us from start to finish.


Arrange Installation

As soon as the grid grant permission for the installation, Cahill Renewables arranges a date to complete installation on. Solar installations rarely take longer than a day.


Save Money and Reduce CO2

Once the installation is complete, a team member will guide you through the system, set up a monitoring app on your smartphone and give you all the information required.



At Cahill Renewables we pride ourselves on thorough pre-sales service as well as our after-sales care. If there is anything that ever requires clarification we are a phone call away.
