Solar Panels and UK Irradiance Levels

A concern raised by those who are learning more about solar panels is usually whether or not they can be effective in Britain’s temperamental weather. Although England might not receive as much sunshine each year as somewhere closer to the equator, solar panels can still work very well.

The levels of the sun’s power are called ‘irradiance levels’ and it is these which determine how well solar panels can work. Solar panels can still be very effective even on less bright days as it is the amount of light that hits the panels which makes them work, rather than heat or sunshine.

Until recently, solar panels were not particularly prevalent within the UK. The introduction of the government-backed Feed-in Tariff in April 2010 has incentivised the uptake of solar panels within the UK which had resulted in many more installations.

Other EU countries such as Germany, the Czech Republic and Spain have had their own Feed-in Tariff schemes for a number of years now, and as such, solar panel installations are much more prevalent in those countries.

Germany has had a Feed-in Tariff since 1991. In the decade since it was introduced, 17,370.00 MWp of solar photovoltaic capacity has been installed in the country (at the end of 2010). Interestingly, the levels of irradiance in Germany are remarkably similar to those of the UK. We receive nearly the same amount of sunlight each year as Germany does. Yet our total installed photovoltaic (PV) capacity is much lower, at 149.99 MWp (as of 1st August 2011).

This demonstrates the level of influence that the introduction of a Feed-in Tariff can have on a nation. It also shows the UK’s level of solar potential. With comparable levels of sunlight to Germany, and now with a comparable Feed-in Tariff to incentivise uptake, the popularity of solar panels in the UK is beginning to increase.

In April 2010 when the Feed-in Tariff was introduced, the total installed capacity of solar PV in the UK was 0.98 MWp. This rose to a total of 78.00 MWp a year later and again to the current installed capacity of 149.99 MWp.

The UK potential for solar power is enormous. Nearly every home in the UK has a roof which could accommodate solar panels. Not only can solar panels produce clean green renewable electricity for use in our homes, businesses, schools and organisations, the Feed-in Tariff ensures that we would be paid for the electricity our panels produce.

Irradiance levels can differ slightly within a country as the amount of sunlight received can vary a little according to location. Within the UK, homes in the south, particularly in the south-west of England will receive the highest irradiance levels in the country. Panels on a south-facing roof in Bristol, Plymouth or Cornwall would receive higher levels of irradiance than somewhere further north. However it is important to note that solar panel arrays which have been installed in the north of England and even as far north as Scotland still perform very well.
