DIY solar cell wiring in series/parallel?

We Answered:

The strings should be of equal length before connecting in parallel. so you have only one choice, since 46 divides into 23 and 2, you can use two strings of 23 each or 23 strings of 2 each. 23 cells is 12 volts. Other connections will waste power.

Look at it like connecting batteries in parallel.

If you do use series/parallel strings, it's best to use diodes in series with each string. That wastes a bit of power but allows the array to operate if part of it is in the shade.

You could connect two unequal sized strings in parallel if you use diodes, but the only one delivering power would be the longer string, unless it gets shade enough to lower it's voltage so the other string can take over.

I was looking into solar panels!?

We Answered:

I have included the link to sources of information that will help you calculate your solar panel cost, need, and amount of roof space.
You need to know how much kW you use a month for the calculations. The great thing is the calculator will take into account you area, utility, and state rebates or incentives.
I would recommend doing your homework on what to expect and the components involved. For myself, I would hire a contractor to do the work on the roof and for a guarantee of some sort.
