Hello everyone I am in the middle of designing a shed for the back yard since my tiny one will not hold all that I want. One thing I want to do is cool/heat the shed so my dogs can use it when it is too hot/cold, but not connect to the grid.  I think to heat it I will have to for now but to start I bet I can build it with some solar panels and a windmill to power a single air conditioner. I just wanted to give you all my thoughts and see if I am in the ballpark for having the appropriate power for the job.
The Facts: The shed will be 20ft X 20Ft with a 8 ft ceiling & well insolated. The air conditioner is not selected for sure but would be comparable to something like this: Heater/air conditioner I will have at least 2 100 watt solar pannels rated for 24V charging. I am looking at getting a windmill like this: 1600 watt 24v PMA type windmill The solar panels will be stationary but at a good angle and relation to the sun. I live an a catagory 2 area for wind speed averages. The mast will be only about 20ft up in the air and not a lot around to block incomming winds. That is the lot of what I would think be important for you all to know. Understand I will have an appropriate battery bank, charge controller, inverter..... I know all that can have an affect on the end result but assuming all that is good what do you think about the above setup? I am looking forward to any feedback or critisism so I can better plan. Will it work? Well lick your fingers and touch the two leeds. PZZZZZZZT |

Hi Arpolis Heating and cooling is one of the most energy wasting things to do, what I would di is check your ground temperature 4 foot down as that might give you enough heat to cool the shed in the summer and warm it in the winter, also if you get reasonable sun in the winter a solar hot water service set up as a hear bank will work as well but the geo thermal is cheaper if you can get a reasonable ground temperature.

Hi Arpolis, One thing in your favor is the guestimated storage taking up a reasonable amount of area and if you don't intend to work in the shed another plus in keeping needed energy levels down.They'll be cool/hot dogs!Cheers Rastus see Rastus graduate advise generously |

I am terribly unknowing of geo thermal tech but that sounds interesting. How would that work? Hmmmmm possibly dig a deep hole, run some coiled copper tubing in there and burry, pipe that up to a ratiator, fill with water, attatch a pump and have a fan blow through the ratiator? The deeper I go the hotter/cooler it will be compaired to air temp.... I might give that a go. Will it work? Well lick your fingers and touch the two leeds. PZZZZZZZT |

Don't use copper pipe. Use black poly pipe or similar. The copper is to expensive, and you can just run longer poly pipe to get the same heat benefit |

Have been interested in cooling/heating via attic fans or underground. If you google this subject you will be amazed how much info there is out there. Taxation as a means of achieving prosperity is like a man standing inside a bucket trying to lift himself up. Winston Churchill |
