Are Solar Panels Worth It?
The cost of solar electricity is around 9p per kWh without export income. If you take into account 50% export paid at 5p per kWh, the lifetime cost per kWh is as low as 7.5p...
If you are a homeowner and you intend to stay in your house for a reasonable time (7-10 years +), a solar PV installation makes seriously good sense.
Here are the main reasons hundreds of our residential customers installed domestic solar panels:

Domestic solar panels usually cost around £1,400-1,750 per kWp installed, depending on roof access costs, roof covering and roof pitch (flat, sloping etc). A 4 kWp system will cost anywhere between £5,500 and £7,000 inc VAT.
A kWp typically gives a saving of around £100 per year, so £400 per year for a 4kWp system, giving a payback time of around 15 years. The panels will last 25 years or so (with one inverter replacement expected during this time). The % return over 20 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.
On average over 25 years (taking into account degradation of panels), a kWp will generate between 850kWh and 1000kWh a year. That's around 20,000 kWh over the life. Before maintenance costs the unsubsidised cost per kWh of solar energy is only 9p. Now that's something to shout about!
If you then subtract the export income, assuming 50% of solar is used on site, the cost per kWh falls to around 7.5p per kWh! The grid cost is 15p+ for the typical homeowner, and rising .... and rising.... and set to rise a little bit more when the coal fired power stations have all been shut down (target date: 2025).

If you are considering installing solar PV, we strongly recommend you consider battery storage at the same time. Click here for more information.
Note that when battery storage is installed at the same time as solar PV, the 5% VAT rate applying to the solar PV installation will also apply to the battery storage system. 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 retro-fitting storage at a later date.

The Microgeneration Certification Scheme was set up in 2008 to protect consumers - and provide reassurance to them - by setting such standards and requiring manufacturers and solar PV installers to register for the scheme in order for installations to be eligible for the Feed-in Tariffs (closed 31st March 2019). Spirit is inspected every year to ensure that we continue to exceed the required standards.
