Green building: The science behind solar panels. We take a look
at the science behind one of the most talked-about alternative
energy sources in the world today. |Millions of people across
the globe use solar power on a daily basis to help meet the
energy demands of their everyday lives. But how many people know
where this solar energy comes from? While solar power does of
course originate from the sun, there are still many different
states that the power has to go through before it becomes usable
energy. Here's an inside look at the science behind solar
panels. Solar panels - the basics.The heat from the sun can be
used to heat water or air for residential, commercial and
industrial use. Sunlight can also provide heating or be
converted to electricity using solar electric panels. Solar
(photovoltaic) panels convert energy in the form of light from
the sun into electrical energy. Between 4 and 22 percent of the
energy falling on the panel is actually converted to usable
electrical energy. The rest is reflecte
