We’ve tried to make the process as simple as possible.
Contact Us
Firstly, get in contact with us via our contact us page, or by calling the office on 01454 619 542. We will initially take some details before one of our electricians will be in contact.
initial design
Following our engineers call, and obtaining further information, we will provide some initial designs, costings and various systems, including just solar, or solar and battery.
on-site survey
If our initial design is of interest then we will visit your property. On this visit we will take thorough measurements, inspect the proposed location of the solar panels and carry out a structural and shade survey.
installation
Once we've had approval and materials have arrived, our electricians will arrive on the agreed install date. Our friendly team will carry out the installation to our high standards and fully walk you through your new solar pv system!
Complete Solar, Battery & EV Charger Installations
With electricity costs rising at rates previously unheard of it has never been more financially viable to begin self-generating your electricity.
Even with small solar systems and arrays, the benefits of generating ‘free’ electricity can be immediately seen. A typical home PV system can generate around 40% of the electricity a household consumes in a year.
With conscious usage, your self consumption numbers can also be increased. If you can begin to time your electrical appliances, such as your washing machine, dishwasher and tumble-dryer, to run throughout the daytime whilst the sun is shining, then your imported electricity will drastically decrease.
Even if you don’t have any washing to do, any excess solar power that is generated that you do not consume can be sold back to the grid!
Previously, with the costs of batteries, and the lower electricity price, it didn’t always make sense to invest in a Battery Storage system. However, the tides have changed.
The benefits of having battery storage will allow you to increase your self-consumption of your solar generation. This will allow you to store your unused solar generation during times of low electrical demand (during the day whilst you are at work and children are at school). You can then draw from the batteries during the high-demand times and use your own self-generated electricity rather than importing from the grid.
We have on average seen the self-consumption numbers go from around 35/40% to 75/80%, further reducing your energy bills. Our proposals will detail the difference in ‘buy-back’ times for standalone PV system VS a PV and battery system.

You can really start driving on green electricity!
We install EV Chargers that allow you to divert your excess solar generation to begin charging your Electric Vehicle! Such chargers as the MyEnergi Zappi and the Hypervolt will notice when you begin to export your solar generation, and in turn divert that to your electric vehicle.
This is great when you are parked up at home during the day whilst electricity rates are high as you can fill up for free!
Similar to the EV Chargers, we are able to install immersion diverters which work by diverting any excess solar generation to your immersion heater!
The principles are the same as battery storage, but instead of storing electricity, you are storing hot water.
They have a really quick return on investment, and can be installed at a later date should you want any additions to your solar setup!
Our Feedback
5/5
C W Electrical did an excellent job on my domestic Zappi solar EV charger installation. It's been working without a single issue since being installed several months ago. The end to end service was extremely professional, including excellent no-nonsense training on the installed hardware & user interface. EV chargers are relatively new technology - so you need someone who knows what they are doing, and I would certainly recommend C W Electrical as a trustworthy installer for this type of work!
Mr Le BlondZappi Installation
Had an EV charger installed by Chris and team, very quick and professional service with what I was expecting to be a tricky cable routing turning out to be no problem at all for the team.
I will definitely be using CW Electrical in future for any further electrical work!
Mr LaceyEV Charger Installation
The service was excellent. They arrived on time and started immediately not standing around chatting like some workmen. They were very polite and very friendly. They talked us through everything they were going do which put our minds at ease
Mr PetersHypervolt Installation
I initially had made an on-line enquiry to CW Electrical on a Saturday morning, not expecting a response until the following week. I was really pleased to receive a phone call from them before 9am the following Monday. So often these days companies don't respond quickly or not at all.
CW Electrical did respond and this was the major reason I chose them to carry out the work - communication.
They also kept in touch prior to the work commencing, keeping me informed of when the start date would be.
They arrived on time and with the minimum of fuss carried out the electrical installation - a car charger unit and replacement customer unit.
This was my first experience of CW Electrical and as a result of I can thoroughly recommend this company and will certainly be in touch with them again when I next require any electrical work to be carried out.

Frequently Asked Questions
Find some FAQ’s we’ve answered. Should you have further questions we will be more than happy to answer them.
Sadly not, but don’t panic! During the Spring Statement 2022, Chancellor Rishi Sunak announced that installations will be VAT free for Solar PV systems.
In theory, providing a 20% reduction!
The previous VAT was charged at 5% for Solar installations, so this latest update provides a further 5% VAT deduction.
Personally, we think it is incredible that the government have not implemented any further grants considering the constant reminder to be greener!
You’ve probably heard that you need a South facing roof, and yes, this is ideal – but don’t fret if not. Losses are only minimal when facing between East and West, and even North facing systems are possible.
The optimum angle for solar irradiance would be at a 35 degree inclination, pointing due South. If the system faces completely West or East, then you find the system to be 25% less efficient. A South West or South East facing roof is only 5% less efficient from a completely South facing roof.
Even a completely North facing roof is only 45% less efficient. And even in these cases you can just increase the amount of panels installed to increase your energy generated!
Not all roofs are made equal! And a large array of panels can begin to weigh a lot. For this reason we will carry out a roof structural survey to ensure that the roof is in a good enough condition for us to safety install the panels.
