Hi. Further to my questions about 'just right' system for remote cabin where only electric appliances are a fridge (2 A) and a fireplace blower (1.5 A), during three summer months. What I've understood for sequence of decisions is:
- First determine what system capacity you need. Attached is an energy audit and sizing tool (excel) from the forum. I flipped this to Daniel, who is doing an analysis. He said it is very handy.
- Next thing is the inverter..... make sure the capacity of the inverter can handle your future needs
- Next is the Solar charge controller. If you don't buy a large enough one, you will have to add a 2nd one when you add panels.
- Then consider the batteries. There is no one size fits all answer for batteries. I DONT YET HAVE A CLEAR PICTURE HERE.
- Then panels. Many options here, included used and rebuilt. They are generally few differences between panel choices, with many doing the job.
