I would like to know how to use the sun energy for my home at little or no cost to me.? I live in Phoenix, AZ so I don%26#039;t have lack of solar energy. I hope someone out there can send me in the right direction.
Thank you,

• Active solar involves panels or tanks to harness the sun%26#039;s power; but you want no cost so passive solar is the way to go.
  Essentially, at times that it%26#039;s cooler (night, winter, etc.), you want to open all of the shades on windows that get a lot of sun and face something that holds warmth well, like a cement floor or brick wall. That item will passively absorb the sun%26#039;s rays and slowly release the heat after the sun goes down, cutting back your nightly heating bills.
  Looking a little more active? There are some systems that can help you warm water through solar power so you use sun-heated water instead of water from your water heating tank. Those systems, usually placed on the roof, do have an initial investment likely higher than you%26#039;re seeking. 33% 1 Vote
