I'm interested in a Solar unit panel that I can build or buy already made, to heat my house as a backup heat.
Question:
Answer:
You can get free information on how to build a solar space heater or if you like a solar air heater and free prints. It is in PDF format but prints out just fine. It has a "free not for resale" water mark on each page but is not blocking any info that you need. Some one would have downloaded this one and been selling it on Ebay if it did not have that water mark.
The heat is not going to be free that is for sure, and to make a difference you will need more than the number of photo cells to take up the small space a skylight might occupy. The panels are pricey. Call your local HVAC (heating & air conditioning) company and ask what they can do for you and give you a little information about capacity. Are you looking to hook into the electrical grid or heat water = two seperate systems. I'm building a home right now for a person right now who wanted the same thing, I got my best FREE info from the HVAC people.
there is a book called sunshine to dollars that is actually pretty useful I am ordering it just for some of the ideas
There are several ways to use solar heating in your home. I don't believe solar panels is one of them. This is a subject that I have been studying myself for a few years. You can either use air or water. Repiping the walls in your home would be expensive, so air would be a better way to go.You can build heat collector frames over your windows actually collect the sun's heat and pulls it inside your home.
