Nice article, though it would be good to hear more about input costs such as insurance. What is the monthly cost for insurance? What is your electricity cost per kWh? What about adding a battery and solar power supply?
Not sure where you live, but at the coast we have nocturnal geckos that will no doubt ruin a rig if it's not sealed somehow. It would need to be connected to an aircon via a duct and be closed (possibly perspex).
Anyone have suggestions for suppliers?
