Passive Solar Energy

Passive solar thermal technology is employed for collecting and converting the sun's energy to heating applications such as water and air heating, cooking and drying, steam generation, and distillation. To accomplish this, a solar thermal collector device absorbs and stores heat. Solar thermal technology requires good heat conducting materials, insulation, and reflectors. Solar geysers, solar concentrators, and solar cookers are some examples of devices based on solar thermal technology.

Also, solar energy can be put into use by incorporating appropriate designs in buildings to maximize utilization of solar energy for various purposes such as lighting, air conditioning, and water and space heating/cooling and thereby reduce external energy inputs. PV cells require high exposure to direct sunlight. To assure maximum exposure to the sun throughout the day, a phyrheliom-eter is used to calculate how much sun exposure a location experiences. This information is useful in determining whether or not a specific location is suitable for solar energy, as well as what direction the cells should face. In many cases, these cells are placed on rooftops.

Getting Started With Solar

Do we really want the one thing that gives us its resources unconditionally to suffer even more than it is suffering now? Nature, is a part of our being from the earliest human days. We respect Nature and it gives us its bounty, but in the recent past greedy money hungry corporations have made us all so destructive, so wasteful.
