nasa solar energy data, radiant gentle and heat from the sun, has been harnessed by humans because ancient times working with a range of at any time-evolving technologies. Photo voltaic energy technologies consist of photo voltaic heating, solar photovoltaics, solar thermal electricity and solar architecture, which can make substantial contributions to fixing some of the most urgent troubles the world now faces.
Photo voltaic technologies are broadly characterized as either passive solar or energetic photo voltaic based on the way they seize, transform and distribute solar power. Active photo voltaic techniques include the use of photovoltaic panels and photo voltaic thermal collectors to harness the energy. Inactive solar strategies contain orienting a constructing to the Sun, choosing supplies with favorable thermal mass or mild dispersing attributes, and creating areas that by natural means circulate air.
