It is possible to install residential solar power systems which produce electricity for use at home.

These can be used surprisingly far north or south of the equator, as solar cells and solar panels have become much more efficient.

They even produce some electricity on days when it’s cloudy, although obviously less than when the sunshine is direct.

Recent improvements in the design of solar technology has made it a much more interesting and affordable option for those who want to reduce their electricity bills and carbon footprint.

Economies of scale have helped this, as far more cells are being produced, and the technology has improved as well.

Since 2002, the production of solar cells for solar powered electricity has been increasing by an average of 50% every year. In addition, installation has become not only far more efficient, but much cheaper.
