A great way to go about choosing the wire thickness for your solar system is to buy solar panel wire big enough to cope with the biggest current amp drawing appliance you have and using that wire for all the other runs to the ac breaker panel.
How do you wire a solar panel system.
At the back sides of the solar panel a small junction box is there with a positive and negative sign for polarity.
In a large size solar panel this junction box has terminal wires with mc4 connector but for small size panel you have to connect the junction box with external wires.
Use a wire sizing calculator for solar arrays that will figure out the size of wire you need.
To have a functional solar pv system you need to wire the panels together to create an electrical circuit through which current will flow and you also need to wire the panels to the inverter that will convert the dc power produced by the panels to ac power that can be used in your home and sent to the grid.
You want a 24 volt system so you wire 2 panels in series to make 24 volts.
10 solar panels rated at 5 amps at 12 volts.
Most solar panels and batteries come in 2 24 36v etc.
Wire the solar panel.
Enter the 25 as the maximum amps your wires need to carry.
This allows you to have the right number of panels to meet your home s energy needs without exceeding the limits of your inverter.
You do this 5 times.
Suppose a single battery powers up a ceiling fan for 6 hours.
But solar panels are rated in watts so some simple conversion math is needed.
This means the solar panel each day will have to supply 1 percent of the battery s total amperage to maintain full charge.
Understanding the basic principles of design and what type of system or diy solar kit you ll need will help you maximize solar efficiency.
The thing is most solar panel systems are larger than 12 panels.
For example a solar panel must be capable of producing 0 5 amp hours of energy per day to maintain the charge on a 50 amp battery.
The same fan can be powered up for 12 almost double hours by two batteries having the same capacity connected in.
Solar panels have an efficiency rating with a 0 5 to 1 drop every year.
In the solar industry.
However if you are switching entirely to the solar power you will have to purchase and install batteries that store the solar power for use at night.
And learning the ins and outs of solar system design will help you choose the right diy solar panel kit for your needs.
If you want to add extra capacity to the system you will have to wire the system in parallel configuration.
