What makes DCR the very best Solar PV installation and maintenance specialists?

We are a local, established electrical and mechanical business that have been operating since 2007.
At DCR we put our hearts and souls into what we do, we care about every customer and every installation.


At DCR We have been installing Solar PV systems and renewable energy products for 15 years. We have lots of experience fitting Solar PV systems and have refined our products and installation methods over the years.

DCR Stability

We are a financially stable business and can offer our Experian credit report to prove this along with our quote. This is very important when choosing a Solar PV company. You may need to call on your system warranties in the future and it is essential that the installation company are still trading and can honour your warranty.

DCR Staff (No Sub-Contactors)

Our staff work directly for us and we do not use sub contractors other than specialist contractors like scaffolders. We have a very low turnover of staff which means our engineers have been able to understand exactly what is required by DCR and what is required by the client. We believe our standard of workmanship is far greater than any other business.

No Salesmen

All our staff are electricians and electrical engineers. We look at every job individually and work out what is best for you the client.

Care and Attention

At DCR we care about you and your system.
We pride ourselves on giving you the very best experience and the very best system possible. To date we have 100% customer satisfaction on Solar PV installations. The reason for this is that our service is exceptional and we make sure you are happy with your system. We will walk you through the process once we are finished to talk you through what has been done and to make sure that you are happy with everything that we have delivered.

DCR Products

At DCR we care about you and your system.Over many years we have witnessed and understood the various pit falls in the renewable energy industry.
One of the biggest is the poor quality products that are being sold. We always choose manufacturers and products that are tried and tested. We prefer to install more expensive, higher quality products so that your system will out- perform that of a cheaper system and with far less problems, hence saving you money over the course of its lifetime.

DCR Aftercare

Our aftercare is second to none. We have experienced engineers readily available to help in the future should you have any system issues or should you just need any general assistance with your Solar PV system.
