Basic DC solar PV system

Energy Needs

• Total process energy = 19.3 MJ + inefficiencies• Total process power = 300 W + inefficiencies

PV components

• Panels – need ~500 Watts• Charge Controller – 12V at 50 Amps• Deep Cycle Battery –12V ~35 Ah

Total Cost

• PV panels = $440 plus shipping?• Charge Controller = $87• Deep Cycle Battery = $65 + shipping• Wiring (estimated) = $20• Total cost = $612

Notes/comments

• This will take 2 days to complete process• Do we need a PV panel(s) that outputs 12V or

will any voltage work (compatible with charge controller?)
