What is PV?

The performance of Solar PV can change due to the intensity of the sunlight hitting the cells. Basically, if it is a bright, sunny day with no clouds in the sky, the irradiance from the sun will give us more power and output than on a duller, cloudier day. The key fact to remember is that solar PV panels create energy from daylight, not just direct sunlight. This means that solar PV systems are a practical solution for our climate here in the UK and they can be fitted to any house or commercial roof with an orientation of up to 90 degrees from the south.
