Solar panels usually cost around £1,400-1,750 per kWp installed, depending on roof access costs, roof covering and pitch. A standard domestic 4kWp system will cost around £6,000 inc VAT.
As 4kWp typically saves around £400 per year on energy bills, the payback time is around 15 years. The panels will last 25 years or so (with one inverter replacement). The return over 25 years is usually in the order of 9% (IRR%). This is non-taxable, so compares very favourably to any other investment, especially one that depends only on the sun coming out.
The grid cost is 16p+ per unit for the typical homeowner, and rising... and rising… Including maintenance costs, the unsubsidised cost per kWh of solar energy is only 8p. Now that's something to shout about!
We’re MCS approved solar PV installers – an award winning, specialist company that has installed over 2,000 solar systems since 2010.
The Microgeneration Certification Scheme (MCS) protects consumers by setting high standards for registered manufacturers and solar PV installers. Only MCS approved systems are eligible for export tariffs. Spirit is inspected every year to ensure that we continue to exceed the required standards.
We are passionate about solar technology and all of our systems utilise best-in-class technology, customised to meet your requirements.
We don’t employ pushy salesmen – just technical people, passionate about renewable energy, who will provide you with a solar PV installation combining technical excellence and value for money. Our quotes are detailed and clear, with no hidden costs. As PV systems typically last 25 years or more, we are here to support you and your system over the long term.
All projects are managed in house and installed by our solar panel installers.
If you are installing solar PV, we strongly recommend you consider battery storage at the same time.
With home batteries, you can store your excess solar energy to use when the sun goes down - or in a power cut. With smart tariffs, you can save even more by buying cheap off-peak electricity and selling when demand is high.
When battery storage is installed at the same time as solar PV, the VAT rate applying to the solar PV installation will also apply to the battery storage system (which may be the lower 5% rate). Furthermore, there is a saving to be made by purchasing an all-in-one inverter / charger. Overall, savings of over £1,000 can be made by installing battery storage at the same time as solar, rather than retrofitting storage at a later date.
