The two common conductor materials used in residential and commercial solar installations are copper and aluminum copper has a greater conductivity than aluminum thus it carries more current than aluminum at the same size. 33 kwh 6 1 sun hours x 1 15 efficiency factor 6 2 kw dc solar system size required using the example above with a 6 2 kw dc system you can multiply this number by 1 000 to confirm that you need 6 200 watts of solar panels. 6 2 kwh x 1000 convert to watts 6200 watts solar panel required. This solar wire size calculator calculates the wire size of copper wire taking into account electrical parameters of the solar array or another device power voltage and current and cable s temperature working conditions as well.

The size of the conduit will depend on how long a run ac or dc number of circuits wires and size of wires it will hold. Usually 12 24 or 48 volts. Wire types vary in conductor material and insulation. Enter the total amps that your solar panels will produce all together.

However for the aspiring solar diy er knowing how to install solar panels can seem daunting. The ends of the conduit should be clearly labeled particularly if the intent is to install the pv system at a later date. You have two different higher voltage solar panels i e one 100w 24v and one 200w 24v that you want to connect to the already working 12 v solar power system comprising the two 12v 50 w solar panels connected in parallel from the previous scenario see the picture above. Enter the distance in feet from your solar panels to your battery bank charge controller.
