"We're a family-run solar specialist that has been installing solar panels and battery storage systems throughout the South of England since 2010. We pride ourselves on our 100% in-house technical expertise and installation work, as well as our attention to detail, industry-leading design work, customer care, and the quality of our post-install support.
Installing solar PV & battery storage is such a large investment that it's paramount to work out the best specification and system design to maximise your return on that investment and make sure that the system ticks all the boxes. As such, we provide a free, bespoke design service for all of our clients, and are prepared to go back to the drawing board as many times as it takes to finely tune the design and achieve the best system and investment return for every household and building.

My aim at Spirit is to make sure we get the right renewable energy solution for your home or business. It is a great feeling to take yourself off grid and generate your own power without needing to worry about power cuts or an increasing energy price over the next 25 years.
I have an in-roof PV installation at my home with a zappi and eddi. Having the technology you sell on your own roof fitted by the company you work for really helps to understand how the system works and what sort of experience a customer expects.
"At Spirit, we don’t believe in pushy salesmen. We employ well-trained and knowledgeable technicians who know our products, are up to date with the regulations and can carry out technical calculations. This lets us provide you with a detailed quote and plenty of guidance on what the best system for you is."
-Mark Golding, Head of Sales
Justin is the backbone of the company and part of the leadership team. He has overall responsibility for the installers, electrical design and sign off of all systems as well doing a technical and structural survey for every project to ensure we can manage each job perfectly. His devotion and meticulous attention to detail has helped build Spirit into the reputable and trustworthy brand we are today.
You will most likely meet Justin on your technical & structural survey where he will plan your entire installation and run you through every minute detail.
"I know that the technical & structural survey is a step that other installers don't feel is necessary, but many of Spirit's customers appreciate the chance to talk to the actual installers before the installation date."
-Justin Parsons, Head of Installations
