Back again
Previously, we looked at designing a system based on meeting our stated requirement for daily power - 7820watts for Chris, 15kw for me.
The reality of the situation is the systems will produce more power than the requirement. For example, my current 4.5kw system produced an average of 21.11 kw per day the last week of May. That's 4.69 per kw of panel. That's 140% of my daily requirement.
So how would that translate to the above theoretical systems. 83.6kw produced on the 17.82 system - 557% of requirement.
The no-genset 14kw system would have produced 65.68 kw or 438% of requirement. Basically wasted - can't store it in my current battery bank and adding additional battery banks would add an expense without a benefit. Even if on Helco, couldn't sell them that much!!!!!!
Actually, I don't waste my overage - currently, it's free power to power the pool pump - but that's another story
Anyway. I just hope I've given some insight as to why it's important on this forum to temper theory with local experience.
Any questions? Enjoy [}]
