Electricity prices have risen by approximately 7% every year for
over a decade, the average cost is currently 13p/kwh and the
average household using 3300kwh per year, (figures from DECC.) A
1.9kwp Solar PV System can provide 50% of this demand. The graph
below shows the reduction in an £650pa electricity bill for3
sizes of Solar PV system. The effect of fuel inflation is shown
with annual prices rising to over £2000. 2.Solar PV as an
investment Currently you can get a better rate of return by
investing your savings into a Solar PV system rather than
putting into a ISA. A £15,750 investment in a 4KWpsystem will
return £55,000 in payments and saving over a 25 year period.
