So, Larry, what exactly is inverter clipping? – So inverter clipping, Warren, happens when your solar modules are producing more DC power than what your inverter can actually harvest. – And when would you choose to start clipping? – Yeah, so there’s a couple of situations where you might design so that your inverter clips more often.
One would be, if you have a limitation like a transformer size or maybe utility size limitation, where you’ll build the inverter to match that size, and then you’ll have a much larger DC system size. So even though you’re clipping during the highest production times of the day, during those shorter times, you’re still producing the full amount of what that inverter can actually produce.
So that begs the question, Larry, should I rather have more solar panels or more inverters? – That’s the real question, Warren. And that’s something that we look at on a case by case basis. We look at all the variables for your system and determine how big the inverter should be versus the solar module size so that we can build that system to produce as many kilowatt hours per system costs as, as humanly possible.
So in summary, your design team may choose to use inverters that will require some clipping to in order to either save you money or to meet the requirements of the utility company, their transformer sizes, et cetera.
