Voltage Drop - how much do splices cancel out upsizing?

Good point. Thanks.

You’re welcome.

this is a grid-tied PV application so the customer will actually get paid for the energy production that's gained by not losing it to voltage drop.

So what kind of gains are we looking at for upsizing to the #2? I would do the math but you didnt provide length or current. I guess we could just be liberal and assume something like 5 hours per day at full current for a crude guess?

For others who might not have looked at my profile or other posts, this is a grid-tied PV application so the customer will actually get paid for the energy production that's gained by not losing it to voltage drop.

When you run an electric motor for industrial purposes you have to pay for any energy lost due to voltage drop. (same thing really)

There comes a point where it's not practical to up size conductors for these energy savings because they would be minimal.

How long until cost of upsize pays for itself in reduced energy losses is the bottom line either way. Couple years or less, probably worth it. Over 5 years, maybe not.

PV is typically a constant load level for a certain number of hours a day and can be a bigger factor than other loads that have varying load level.
