you must be in a warmer climate.... what panels did you use...? brand etc. what it all cost you???? you didnt show your battery or batteries....Please tell more
so what exactly are you doing with the solar? for the coop? didnt you say you are using AC to heat I mean keep wtr from freezing for the chickens....? maybe I didnt read correctly. Just wanna understand.... saw that can...alumcan framed htr. years ago on solar sites....be nice to do that... Just wish my new coop didnt have slightly tinted windows... on the south side...
The fixed position solar panels are powering a 12v battery system, two batteries, attached to a 400w DC to AC inverter. In all it powers an automatic chicken coop door, a light, and the water heater.
The chicken coop door power needs are from a 12 v battery so it does not work off of the power inverter.
The power inverter is a relatively efficient inverter near 96%. It powers a 4w LED light that is on timer (2, 4, 8 or dusk to dawn setting), and a 50 w birdbath heater in a 5 gal. bucket (filled with water) that uses horizontal nipples. There is no insulation at this time on the bucket. The bucket rests on a 8 inch wood platform.
Some small freezing has occurred when the water heater depleted the batteries after a several day snow storm. Overall using a 24 v system is more efficient to power the inverter which may be my next step since it is free to change.
I had considered going to a all 12v or 24 v system without an inverter. This would help improve efficiency but the cost is stopping me (100 dollars). If I started this project again I would skip the inverter and use a 12 or 24 v system.
