If you want to get free solar energy in the UK then the best way surely must be to get solar panels free in the first place. In the UK many professional solar energy companies are now installing PV, or photovoltaic, panels especially in the South where solar radiation levels are highest. The further north you go, the weaker the power of the sun is mainly because the sun is further away from the overhead position. In fact the power of the sun follows a cosine relationship with the angle of sun: directly overhead, 100% of the suns power falls on the earth whereas at 90 degrees, very little falls directly. You can model this using a tennis ball and a torch and observe the diminishing intensity of the light at the poles of the ball when you shine the torch at its equator. Of course on top of this factor lies the tilt of the earth in its orbit round the sun which creates a seasonal variation in solar intensity too.

But in the south UK the suns strength is sufficient to generate considerable quantities of electricity from the latest highly efficient photovoltaic panels. Over the years the efficiency of mass produced solar panels has crept upwards at the same time as production costs per square meter have been falling and so each year the economics are getting more and more favourable.

In the UK, the government is actively encouraging the installation of free solar pv panels by paying installers a premium price for the electricity so generated. At the moment, the price you get paid per kilowatt hour substantially exceeds the grid price of power which means, provided you have a south facing roof it is frequently possible to install PV panels and get paid. Of course, sorting all this out is quite hard work and requires complex technical installations to connect what are low voltage direct current power sources – your PV panels – to high voltage ac current devices that usually run of mains power. For this reason, many companies are now providing free installations of photovoltaic panels in return for the government subsidies.
