Case Studies

Here you can find case studies for all the types of projects we've worked on. With over 4,500 installs completed, we're immensely proud of the care put into each and every one. Take a look at some of our previous installations for inspiration.

Recent case studies

Pangbourne, Berkshire - 9.135 kWp (Dec '23)

In December of last year Spirit installed a 9.135 kWp system for Mr S of Pangbourne. A large south facing roof allowed for an impressive array of 21 Black Jinko panels.

With the help of a Tesla Powerwall 2 and gateway, Mr S. is expected to use 57% of the energy he generates on site, exporting the rest back to the grid - all while achieving 97% grid independence over a year and 100% in the summer months.


Newbury, Berkshire - 6.72 kWp - (November '23)



Bramley, Hampshire - Powerwall 2 - (Nov '23)



Bracknell - GivEnergy (9.5 kWh + 5.2kWh) (Dec '23)

At the end of last year we installed an additional 5.2kWh battery for Mr A of Bracknell, to compliment his existing 9.5kWh battery and PV system.


Farnborough, Hampshire - 6.12 kWp (Nov '23)

In November of last year we installed a 6.1 kWp system for Mr G, in Farnborough, Hampshire. The system is projected to have an annual output of 5.4 MWh a year and we also installed at the same time a Tesla Powerwall 2 and Gateway system, to further increase the savings the household will have on their energy bills.

Mr G had this to say of the project:

"The installation team worked together efficiently and were happy to answer questions and offer suggestions, such as the best options for the cable runs. When they finished the install they left the place very clean and tidy.

We have been very happy with the way our system has been working since the installation was completed and would certainly use Spirit Energy again for future work."


Spirit House, Reading - 54.61 kWp (Jan '24)


At the end of last year, Spirit Energy decided to follow through on our commitment to cleaner energy by installing solar panels on the roof of our office in West Reading. Initially planning to use 157 panels, we encountered complications with the DNO. Seeing an opportunity with this setback, we decided to make a statement by writing our name on our roof in solar.


Theale Quarry - 315 kWp (July '23)


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.


Porter Garland - EVBox BusinessLine (Sep '20)

In September 2020, Spirit installed an EV charging station at Porter Garland’s offices in Camberley. The company had recently purchased an electric car, taking advantage of the tax benefits for businesses.


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.


Nuvola - 1 x Rolec SecuriCharge (Dec '19)

In December 2019 Spirit installed a Rolec SecuriCharge unit for Nuvola in Swallowfield.


Maidenhead - zappi (Nov '19)

In November 2019, Spirit finished installing a complete system for Mr L in Maidenhead - solar PV, Powerwall 2, eddi and two zappi chargers.


Thatcham - eoMini Pro (Oct '19)

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

Mr E went for the eoMini Pro to take advantage of the £500 OLEV grant for smart chargers. The unit is small and discreet, and offers full monitoring via the app (shown in the image above).


Reading - zappi (Aug '19)

In August 2019, Spirit installed its first zappi version 2 at a house in Reading.


St Giles Hotel - 6 x Rolec BasicCharge Dual Socket (June '18)

In June 2018, Spirit installed and commissioned 6 Dual Socket EV chargepoints at St Giles Hotel in Heathrow, London.


Bishop's Court - 46 Fitting Retrofit (2017)

In 2017, a private landlord contracted Spirit to upgrade the lighting in the communal areas of their property in Bishops Court, Slough. This consisted of replacing 46 existing fittings with a range of new LED lights.


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.
