Passive solar energy was used since the time of the Egyptian civilization. Today, we use photovoltaics, designed for space in the 1950s, in our calculators, some road signs, street lights and lawn decorations. Since the 1970s there has been interest in making solar a more common part of our home, school and business energy supply.
The most common large solar application in homes is a solar water heating system. This differs from the calculator on our desk because it generally reduces the energy needed to heat water but doesn't eliminate it. Growing in popularity are solar applications to reduce whole house energy needs. They work well in the Will County area and a number of reliable companies are available to assist you in identifying a business or home application that fits your needs.
