Solar technology is one of the most ancient forms of technology used by mankind and is probably the most important solution to the latest global issue of the time.
The making of salt by evaporation of saline water near ocean and lake shores is one of the oldest industry known, which runs on solar energy utilization technology. The industries of today are somehow so gigantic that it is creating global challenges for meeting energy solutions made more complex with ever increasing population. Solar technology in its various forms tries to suffice ever increasing global energy demand.
Solar Technologies are broadly classified as Active or Passive depending on the process of utilization of solar energy. A solar-electric system is the best example of active or complex solar technology which involves production of electricity using Solar panels, rechargeable batteries, regulators and controllers, etc. The passive forms of solar technologies were utilized in days gone by to arrange the infrastructures and building in such ways that it would produce natural air circulation.
