how can we conserve solar energy, radiant gentle and temperature from the sunlight, has been harnessed by human beings because ancient moments working with a assortment of ever-evolving systems. Photo voltaic power systems consist of photo voltaic heating, solar photovoltaics, photo voltaic thermal energy and solar architecture, which can make substantial contributions to solving some of the most urgent problems the globe now faces.
Solar technologies are broadly characterized as both passive photo voltaic or active solar based on the way they capture, change and distribute photo voltaic electricity. Active solar methods incorporate the use of photovoltaic panels and solar thermal collectors to harness the vitality. Passive solar approaches incorporate orienting a developing to the Sun, picking out components with favorable thermal mass or gentle dispersing qualities, and planning areas that in a natural way circulate air.
