What Is Solar Energy

Solar energy is electricity made from the light and heat we get from the sun. There are two ways of capturing & using solar energy: passive solar and active solar.

* "PASSIVE SOLAR" describes building techniques that take advantage of the light and heat of the sun. Passive solar building techniques have been used for thousands of years, when ancient Greeks oriented their buildings to the south to provide a natural means of light and warmth. Today passive solar is becoming increasingly popular, as architects work to create naturally well-lit homes that stay within a comfortable temperature range without requiring heat or air conditioning.

* "ACTIVE SOLAR" techniques use solar thermal collectors and photovoltaic panels to harness the energy of the sun for people to use in their homes and workplaces.

Solar Panel Cost Calculator focuses on Active Solar, which includes the use of solar photovoltaic panels.

Active Solar Collectors

Active solar systems use solar panels to collect and store solar energy. Small solar panel systems or solar kits provide electricity for powering lights & appliances, as well as heating and cooling homes, while large-scale solar panel systems can provide electric power for a whole neighborhood.
