Tesla Powerwall 3 is an industry-leading battery system with a revolutionary hybrid solar inverter, expandable battery system, and a lot of built-in functionality.
Spirit Energy is one of the most established and decorated Tesla Powerwall 3 Premium Partners in the UK. We won the Tesla Excellence Award in 2021 and 2024, and typically install over 250 Powerwall units every year. In 2024, Spirit Energy was lucky enough to be selected by Tesla to install the first Tesla Powerwall 3 in the UK
Launched in 2022, Sigenergy has taken the UK battery industry by storm, offering a battery system that is pushing the industry forward with many technological advances. The SigenStor is completely modular allowing for easy future expansion of the battery system.
Spirit Energy works very closely with Sigenergy and we install a lot of single phase and three phase SigenStor batteries with power cut protection.
Givenergy is a prominent, British battery storage brand which offers an extensive range of versatile storage systems to suit all needs.
Spirit Energy is a Givenergy Platinum Installer, and we have installed a lot of their 9.5 kWh batteries as well as the highly regarded GivEnergy All in One.
We look forward to the release of the GivEnergy Hybrid All in One, hopefully coming later this year.
Victron energy is one of the most established battery manufacturers in the world. Founded over 50 years ago, Victron began by building energy systems for commercial shipping vessels. Victron have since ventured into the home battery market, offering one of the most advanced and customisable battery systems available.
Spirit Energy has installed a great number of large Victron systems, particularly for small commercial buildings, three-phase houses, and off-grid systems.

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.
Wentworth Lodge, part of the B&M Investments group, has taken a meaningful step towards sustainability by installing solar panels across its site. The project is designed to reduce energy costs while cutting the building’s carbon footprint, ensuring long-term benefits for both residents and the wider community.
If you want a quick, reliable answer, there are four ways to size a roof for solar: satellite measuring, measuring from architectural plans, measuring in person, and drone survey. Below we go into detail about each method to answer the question how many solar panels you can fit on your roof. Read this blog if you want more than a rough guess.
