About
Solar Energy - How Solar Works
Solar energy is the energy of the sun. Without it, life
would not exist on our planet. We use the sun's energy every day in many
different ways. When we hang laundry outside to dry in the sun, we are
using the sun's heat to do work, plants use the sun's light to make
food, and decaying plants hundreds of millions of years ago produced
coal, oil, and natural gas that we use today. So, even the fossil fuels
that you use today are actually sunlight stored millions and millions of
years ago.
A PV (Photovoltaic) Electrical System is a system
that employs the energy in the sunshine. PV modules (panels) are made up
of photovoltaic cells, and function much like many small appliances such
as calculators. PV modules (panels), are then grouped together in an
array and set outside to capture sunlight throughout the day and harness
its electrical energy. This energy from solar cells can then be used to
directly provide electricity to your home.
