Solar Photovoltaic panels has been around for many decades so the technology is well and truly established. Solar is also the only ‘fit and forget’ technology as it requires virtually no maintenance or service. Most Solar panels come with a 25 year performance guarantee, meaning they will generate at least 80% of their rated power for 25 years.  In the last two years the take up of Solar has increased exponentially and consequently the cost of Solar panels has come down drastically. In October 2011 the cost of a Solar installation of up to 20kW was around £ per Watt. A year later it is around £1.50 per Watt. On this basis a Solar installation on a house can provide annual returns of between 10-14% and a payback of 6-7 years if you include the savings and Government Tariffs. . 

How Much Can I Earn?

A Solar installation will provide Savings for at least 20 years and a Guaranteed Income for 20 years.

Savings – if your consumption is £75/month, and you use half the electricity you generate, then you could save £450/year.
Feed in Tariff – as of 1st November 2012 the FiT is 15.44p/unit. This is Index Linked, Tax Free and Guaranteed for 20 years
Export Tariff – this is 4.5p/unit and it is assumed that 50% of the electricity generated will be exported.

Example : a 4kW Solar system installed on a property in the South of England, with a South facing roof pitched at 30°.
According to the SAP calculation this will generate 3,443kW per year. This translates to –
Feed in Tariff = 3,443 x 15.44p = £531.60
Export Tariff = 3,443 x 50% x 4.5p = £77.47
Total income =£709.07
This income is Index Linked, Tax Free and Guaranteed for 20 years.
