The location and orientation of solar panels affects their efficiency. For example, south-facing panels (in the northern hemisphere) will capture more sunlight and therefore be more efficient. The best solar panels are tilted. This makes them perpendicular to the sun’s rays, which also makes them more efficient.
Solar panels are widely deployed in industry and residential settings. They provide a cheap, clean source of electricity without producing greenhouse gases. There is more than 15GW of solar energy capacity in the UK right now, much of it provided by photovoltaics.
Solar panel efficiency determines how much electricity a solar panel installation will produce. Energy efficiency of solar cells and panels refers to how much of the sunlight that hits the surface of the panel is converted into usable electricity.
When sunlight hits layers of silicon inside solar cells, an electric charge builds up, creating a flow of electricity. Solar panels are mainly located on the roofs of homes and buildings and can generate electricity and heat water free of charge. In the Northern Hemisphere (including Scotland) solar panels work best when they face south.
Very few found that their solar panels could provide all of their electricity needs. But a quarter of those surveyed told us their panels generated between half and three quarters of their annual electricity. The rest they would get from elsewhere – usually mains grid electricity.
Whether they'll generate enough electricity for your home year-round will depend on: if your solar panel system works in a power cut. It may be more realistic to think about whether you can be self-sufficient for the brighter parts of the year, and then top up your energy use from the grid at other times.
