Solar Systems - Active, Passive, Cost
Solar - energy from the SUN. There are two primary types of solar systems; Passive and Active.
Passive Solar Design
Passive solar design refers to the use of the sun's energy for the heating and cooling of living spaces. The building itself or some element of it takes advantage of natural energy characteristics in materials and air created by exposure to the sun. Passive systems are simple, have few moving parts, and require minimal maintenance and require no mechanical systems.
Active Solar Designs
Active solar technologies are employed to convert solar energy into usable heat, cause air-movement for ventilation or cooling, or store heat for future use and for the production of electricity. Active solar uses electrical or mechanical equipment, such as pumps and fans, to increase the usable output of a system.
Average Cost for Small Solar Thermal and Solar Photovoltaic Systems
These average costs for small solar thermal and solar PV systems are taken from a presentation put on by OSEA (Ontario Sustainable Energy Association and Go Solar. www.ontario-sea.org/
