Solar energy is plentiful and essential for life here on earth. The sun is 1 million times bigger than planet earth and by far the biggest source of energy available to us today. In fact, if the human race used only solar energy for all its energy needs (assuming 100% absorption of solar radiation) it would only take 88 minutes of solar radiation to meet our total energy requirements for a whole year!
Solar energy is renewable and clean and there are a number of ways we can harness it for use in our homes and buildings, naturally maximising the solar gain or generating our own energy using solar thermal or photovoltaic (PV) panels.
