Solar technology isn't new. Its history spans from the 7th Century B. We started out concentrating the sun's heat with glass and mirrors to light fires. Today, we have everything from solar-powered buildings to solar-powered vehicles. Here you can learn more about the milestones in the. . Though solar energy has found a dynamic and established role in today's clean energy economy, there's a long history behind photovoltaics (PV) that brought the concept of solar energy to fruition. As the invention was brought out it made solar cells as a prominent utilization for power generation for satellites. [2] About. . Long before the first Earth Day was celebrated on April 22, 1970, generating awareness about the environment and support for environmental protection, scientists were making the first discoveries in solar energy.
