50% of people are below average. (Its a statistic)
What are the reasons for using multiple strings in a solar panel array? I guess the obvious would be;
1. Shading. More strings means, if shading occurs then hopefully its contained to a string and the rest of the array can perform.
2. If a solar panel failed or was in the process of failing then hopefully the power drop would be contained within the one string, and not affect the entire array.
more?
I guess too what I am asking, is the idea to have as many strings as possible, but staying within voltage minimums and maximums required by the inverter? I have 4 strings of 9. For example, would I have been better off to have done 6 strings of 6 ? I don't plan to re-wire my array, just wondering what the thought process and/or design thoughts are when considering number of strings in an array.
