Recent case studies

Connevans Limited - 42 kWp (June '23)

In June of 2023, we installed a 42.08 kWp system for Connevans Limited. They are a firm specialising in the manufacture and sale of equipment for the deaf or hard of hearing. This is the second time Connevans had used our services to install a solar system, the first being back in 2015 but they have since expanded their operation on the site and wanted to expand their solar system in order to be as close to self-sufficient as possible. 

Connevans were very happy with the install, and we were happy to help them with their business objectives and green ambitions for grid independence. With the initial system already outputting 27.08 kWp and having more than paid for itself since its installation in 2015, they look forward to an even shorter payback period with the new system, with the efficiency of the Trina panels greater than the older model that was used on the 2015 install and the increase in energy prices both helping to improve the payback period. We also helped them further shorten their payback period by referring them to an energy broker which led to an estimated payback period of just four years for the 2023 install.


Woking, Surrey - 14.35 kWp (June '23)

In June 2023, we completed an install on a detached property in Woking. The client was technically minded, but was still very happy with the quality of the work done and the professionalism and attention to detail at every stage of the process. The client opted for 33 SunPower panels, making this one of our larger domestic installations and is looking to install an Enphase battery at a later date to make the most of the 14.35 kWp system. 

Listen to what Mr C had to say about the project:- 
"System design was great. Sam Gilbert listened carefully to what we wanted to achieve and then spent a lot of time figuring out how best to achieve it...

Project management - great. I was concerned that taking the chimney down just before the panels went up would be stressful, that the scaffolding wouldn't be there in time or the installers would arrive before we were ready. You made it very easy...

Installation. Fantastic. The wiring to our new distribution board is a work of art.
" ~ Mr C


CPV Ltd - 491 kWp (February '23)

Ascot - Tesla Powerwall 2 (13.5 kWh) (Aug '20)

In August 2020, Spirit installed Powerwall 2 for a client in Ascot, Berkshire. We mounted the weatherproof battery and gateway on the outside wall of Mr B’s home, with the cabling going through to the distribution board inside.


Tonbridge - 2 x Tesla Powerwall 2 (27 kWh) (Oct '19)

In October 2019, we returned to a regular Spirit customer in Tonbridge, Kent to add an additional Tesla Powerwall and zappi EV charger to his home energy system. The previous year we installed a large 6.72kWp solar PV array and Powerwall.

The second battery will allow Mr C to soak up even more solar energy from the system on high generation days, as well as storing enough to power the home in a blackout.

Mr C said, “Spirit Energy did a great job with the installation. They were incredibly professional, helpful, and reliable. The Tesla batteries with the solar panels have saved me a lot of money.”


Northwood - Founders Series Tesla Powerwall 2 (13.5 kWh) (Oct '19)

Thatcham - eoMini Pro (Oct '19)

In October 2019, Spirit commissioned an eoMini Pro charger at a house in Thatcham.

Bishop's Court - 46 Fitting Retrofit (2017)

NCR Bodyshops - 30 Fitting Retrofit (Jul '17)

July 2017 saw Spirit carry out a 30 fitting LED lighting retrofit for a commercial property in Newbury, Berkshire. NCR Bodyshops wanted existing highbay lights in their warehouse to be replaced with new 220W LED equivalents. 


Primrose Offices and Warehouse - 125 Fitting Retrofit (Jul '16)

In July 2016, Meika Ltd contracted Spirit Solar Ltd to install LED lights in its office and warehouse complex in Reading, replacing 125 existing light fittings and bulbs.

The new fittings range from 600mm x 600mm panels in the office and meeting rooms to 80W LED Corn lamps and 5ft tubes in the warehouse. 

Energy use will be reduced by up to 65%, with a total annual reduction in electricity use of just under 15,000kWh. The annual savings in running costs and replacement bulb costs will be £1,765+VAT; the project has a 3 year payback.

The installation will also improve lighting quality and reduce the need for maintenance of the lights. For example the panels give 35,000 hours service, which is 20 times the expected life of the existing fittings.
