Is there a nifty build calculator that considers distance, voltages, wire gauge etc

[KnobCountry]

I'd like to put an array about 90 meters from the house. I'm not sure on size other than it will probably be less than 2kw.


I would like to play with number of panels, distance vs wire gauge, estimate mppt needs etc to maximize production and limit costs.

Are there any nifty system build calculators that I haven't discovered that could help or do I need to open a few tabs and get working?

I think this will serve your needs.

Voltage Drop Calculator

This free voltage drop calculator estimates the voltage drop of an electrical circuit based on the wire size, distance, and anticipated load current.

I use JCalc, which works in metres and is based on the Au/NZ wiring codes, gives you a LOT of options, AC or DC wiring, voltage drop for the various size cables (in mm^2) with various mounting options (exterior, in conduit, in walls, under insulation, underground etc and works with any voltage you care to plug into it at any distance (or just the usual mains voltages found in most of the world)

Red is a bad choice, green is good

Thank you those are both great tools.

Often the higher voltages of series panels means that voltage loss is not as critical as long as voltage at the controller and/or inverter exceeds the minimum. Current carrying capacity should drive wire gauge.
