Spirit Energy has been installing solar panels on pitched roofs since 2010. On-roof solar panels are one of the most cost-effective ways to generate cheap, renewable energy to power your home and its all about making the most of your roof space and maximising the surface area covered by photovoltaic cells. Our job as designers is to get the most out of you roof and in turn maximise your rate of return.

Installing solar panels on flat roofs is a very sensible thing to do, and with flat roof solar it's all about scale. The more panels that you can squeeze on your roof, the better the economy of scale. Flat roof solar panels are very cost-effective, and there are different types of flat roof mounting systems available. As with pitched roof solar panels, it's all about maximising the surface area with photovoltaic cells.

If you have a lot of land then it makes perfect sense to install ground mounted solar panels. Unlike roof-mounted systems, you get a lot more freedom with ground mounted panels as you can angle the panels perfectly south and set them up to be at the optimal pitch to maximise solar generation.

Ground mounted solar panels are all about scale, and tend to be very cost-effective if you're looking for a system with more than 20 panels and relatively short cable runs.

Mounting solar panels on your wall is a great way to maximise the potential solar generation at your house. Wall mounted panels are very cheap to install, and typically outperform roof mounted panels in the winter months when the sun is lower in the sky.

Spirit Energy has installed a lot of wall mounted solar panel systems and our clients have been very happy with the results; commenting on the more steady generation numbers throughout the year.

Installing solar panels in roof allows you to generate electricity from your roof while maintaining the sleek, clean look of your roof.

Integrated roof panels would replace the tiles on the house and as such make a lot of sense if you're building a new home, looking to add an extension to your house, or if you simply need to re-roof.

Installing solar panels while re-roofing allows you to share costs because the roofers and installers can share scaffolding, and also enables you to save on new roof tiles.

Spirit Energy has installed countless in-roof solar systems, working with brands such as Viridian Solar and GSE.

The myenergi zappi is a highly regarded electric vehicle charge point and has long been the go-to charge point for those looking to charge their electric vehicles from their solar and battery systems.

Spirit Energy has installed countless zappi charge points since the product's release in 2017, and the product is very popular due to its versatility, operating modes, and other functionality including the ability to set an export margin.

The Hypervolt Home 3 Pro electric vehicle charger became very popular in 2024 because of its sleek design and ability to integrate with home solar and battery systems.

Spirit Energy has installed many Hypervolt charge points, and the product comes with a 5 year extended warranty for ultimate peace of mind.

The Andersen A3 electric vehicle charger is a premium, fully customisable electric vehicle charger which can integrate with solar and battery systems.

With our own specialist in-house Andersen EV charger, we Spirit Energy has installed a lot of the older Andersen A2 models, and the new Andersen A3.

Tesla's sleek wall connector electric vehicle charge point is one of our most popular products, and it integrates in very well within the Tesla ecosystem. The Tesla Wall Connector is monitored through the same app as the Tesla car and Tesla Powerwall 3.

Spirit Energy has installed a lot of Tesla Wall Connectors, especially alongside the Tesla Powerwall 3 or for those with Tesla electric cars.

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.

Basingstoke Golf Club - 118.35 kWp (Jan '25)

Introduction

In January 2025, Basingstoke Golf Club took a decisive step in its estate-wide renovation plan by installing 263 high-efficiency solar panels across the maintenance-shed and driving-range roofs. The 118.35 kWp array will generate about 104,000 kWh of clean electricity each year, trimming annual energy bills by roughly £21,000 while preventing 23,432 kg of CO₂ from entering the atmosphere. The project - delivered from first enquiry to commissioning in just three months - now stands at the heart of the club’s ambition to become one of the greenest sporting venues in the region.
