A great quality of service combined with the added value of the Rexel 5 year Production Guarantee, deliver peace of mind to a home owner in Cheam.

The McCue family had lived in their Cheam home for 8 years and were making energy efficiency improvements to become more environmentally friendly and reduce their energy bills. They had researched the benefits of PV solar, seeking views of neighbours with solar, and using Rexel’s Energeasy Solar website to help them make the decision whether to invest. Via the site, they were soon linked with 3 local Rexel Energeasy qualified installers. They selected Techfor Energy Ltd in Guildford as they were most impressed with their knowledgeable, professional and less price-focused approach, and knew that their generation and Feed-in Tariff would be assured by the via Rexel’s 5 year Production Guarantee,

The Challenge

The terraced property was partially leasehold, with a section of the roof being shared. The first floor rooms on one side of the house backed on to those of their neighbours, and therefore the top section of the roof ‘belonged’ to the McCues, and the bottom section to their neighbour. Partial shading from the chimney and trees were accounted for in the energy generation quotation and an additional potential hazard was asbestos in the soffits which had to be circumnavigated.

The Project

A comprehensive quote, roof design and estimate of predicted energy generation, FiT income and energy/cost savings was provided, along with Rexel’s 5 year Production Guarantee. The McCues secured a renewable energy loan via their bank to finance the project and then work commenced. The installation took just over 2 days. They were set up to access Rexel’s online monitoring tool to help them track their energy generation, with the system’s performance also being remotely monitored by Rexel, so that any unusual drop in generation can be investigated and rectified.

 The Solution

A selection of quality products were offered for the 4kWp system and Sharp 250W silver framed panels were chosen with a PowerOne Aurora PVI-3.6 string inverter. Owing to the roof leasehold issue, it was necessary to modify the design for the array as shown in the photo  and agree access to that roof section for the installation. A tricky cable run to the front of the house where the inverter was housed had to be devised, that would comply with regulations.

 Performance Guaranteed

As a Rexel Energeasy Solar installer, Techfor Energy were also able to provide The Rexel 5 year Production Guarantee, for the PV system which was estimated to produce 3,884,83 kWh annually, generating £1,003.90 in FiT income and savings. The McCues’ were extremely surprised at the immediate impact on their electricity bill which had dropped in one month from £57 to £17! Monitoring the system helped identify times of peak production which encouraged behavioural changes, for example using the most power hungry appliances in the afternoon.

Lisa McCue commented, “Right from the word go, Glen Ashby was very knowledgeable and professional. He answered all our questions and gave us a very competitive quote. The office staff always went above and beyond to help. I would definitely recommend!”

"Rexel gives peace of mind to customers who are unsure of the technology and the 90% production guarantee and monitoring system really help consumers make the most of their system. As an installer, Rexel are also a great partner to work with and are always helpful and available" , Glenn Ashby, Technical Director – Techfor Energy
