Suppose that you want to run a 100 watt bulb in your brooder, and that you have tested the bulb and know it provides enough heat when needed.
then the size of solar panels needed can be computed as follows:
100 watts x 24 hours a day = 2400 watt-hours
being you are in Chattanooga the US DOE tells us that you will have, on average, 4.37 hours of solar production per day. so 2400 watt-hours / 4.37 hours = 553 watts of capacity needed on the roof to supply a brooder non-stop. as noted, you will need batteries of the proper capacity too.
At current retail, installed pricing that will run you $6,000 or so, as a DIY probably half of that, If you make panels out of broken parts as suggested ??
All you really need to do for a brooder, a light bulb or two and maybe a heated water can is run one strand of 12-2 w/ground UF style cable which should cost around a dollar a foot to buy. If you then dig your own trench that's most of the labor. make sure you consult your local building inspector to get the proper depth to bury the wire.
