Installing commercial solar panels is one of the most effective ways for UK businesses to cut energy costs, improve sustainability performance, and secure long-term resilience. But a successful project depends on choosing the right partner, one with engineering expertise, strong safety standards, and a proven commercial track record.
If you want accurate solar panel quotes, a technical solar survey, and a smooth installation process, this is the exact step-by-step journey Spirit Energy takes UK homeowners through. Use our solar calculator to get instant estimates, then follow the seven steps below to understand precisely what happens next.
The Feed in Tariff encouraged hundreds of thousands of UK homeowners to install solar panels between 2010 and 2019. Many of these systems are still running today and earning very generous FiT rates. Because the incentives were so strong, the most common questions we hear are:
Can’t have solar PV on your roof? Fear not, you can still benefit from the power of solar energy through smart home battery storage. Home battery storage is fast becoming central to the UK’s energy landscape. Whether you have solar panels or not, a home storage battery lets you store cheap or renewable electricity and use it when prices are high. By 2026, battery systems will be standard across many UK homes, helping reduce bills, balance the grid, and make energy independence achievable.
With energy markets in flux and corporate ESG reporting tightening, solar and battery systems are becoming cornerstone assets for UK businesses. In 2025, government-backed grants, capital incentives, and energy export payments are accelerating payback times and helping organisations strengthen both their sustainability and financial positions.
Across the UK, businesses are under growing pressure to improve the energy efficiency of their buildings. Minimum Energy Efficiency Standards (MEES) currently prohibit the letting of commercial properties below an EPC rating of E, with government plans to raise the minimum to B by 2030. For property owners and facility managers, this shift is not just regulatory - it’s financial. Buildings with low EPC scores are becoming harder to lease, insure, or refinance.
For those who have their finger on the pulse of the solar energy market, it's becoming obvious that there is an increasing shift towards the manufacture and use of n-type solar from p-type panels in both commercial and domestic settings, to the point where the former now dominate. But why has this shift come about, and more fundamentally what is the difference between the two?
In the space of just a few years, the average panel we install on domestic projects has shot up from around 315W to at least 375W, with more and more residential modules breaking the 400W barrier.
This is down to a few factors, such as the widespread adoption of new, more efficient technologies, bigger cells and bigger modules:
When researching solar PV, you may have come across the phrase ‘tier 1 solar panels’. It’s used as a selling point by some manufacturers and installers to demonstrate the reliability of their products. But is that really the case?
