PVwatts will give a decent estimate with most of those variables included: temp, sun angle, sun time, average weather. It generates an hour by hour estimate based that location. It doesn't let you do customization down to your specific panel, but most solar panels are close enough for a decent...

Reading more into it and looking at LinkedIn I'd guess it was more the previous guy was a consultant filling in for a couple years while they searched for someone and then got them up to speed.

Congrats, that's a pretty screaming deal. I read your other thread and you were looking for temperature estimates. If you go to PVwatts results page and download the hourly info, it will give you a spreadsheet that has a field with an estimate of cell temperature each hour.

I think I misread the question

As for the panels they seem fine. 23.6c/watt is a good price, idk if there's gonna be additional freight to jack that price up. If it's an offer others can take advantage of, please share with the class. Just over 19w/sqft is pretty normal. Bear in mind they're huge panels, about the size and...

What I've read is that when a bifacial says 3.2mm, it really means 1.6mm on the front and 1.6mm on the back. Then 2.0mm will usually be 2.0mm on front and back for 4.0mm total. I have seen some panels that say 2.0mm front, 1.6mm back. This really confuses me. I live with the specter of...

Do you have a picture of the shaded and non-shaded array? You said you tried with a different panel in that spot and same results. Have you tried completely removing that panel/location from the string and seeing what happens? What you describe really sounds like the Christmas lights effect...

My only though was maybe a panel being bypassed was putting you under MPPT range, but the math doesn't seem to agree with that. Solark15k Rated MPPT Operating Voltage Range 175 - 420V MPPT Voltage Range 150 - 500V Startup Voltage 125V If you're putting out 3kWh with 8 panels that 375W per...

A 200 amp breaker is designed for loads no more than 160 amps. 160A x 125% = 200A The NEC has 2 breaker size rules 1. You use a breaker of 125% of the expected continuous load. 2. You find actual loads and do a bunch of math, testing, adjustments to find what the adjusted load is and do 100% of...

They're a comedy outfit, billed as the right-wing version of The Onion. But they tend to lean more on the right-wing than the comedy. I.e. making jokes about diversity programs ruining Boeing and not a share price first, safety third culture fueled by massive executive compensation.

Good article. It really would be nice to have certifications for hail resistance. I'm a cheap ass, but would definitely be willing to fork out a few extra pennies per watt to have panels I could count on to not get smashed by a slightly above average hailstorm.

If you haven't looked at PVWatts yet, it could be helpful for you. It's a US government site, but works just as well with other countries. Taking into account sun angles, timing, and average weather. You can run through different scenarios of Bifacial vs Single, Fixed vs 1 axis tracking vs 2...

That looks like a great option. Maybe a little pricey compared to a standard ceiling fan, but Hampton bay isn't moving 25,000 cfm for 100 wh. I'm going to strongly think about this and where it might fit. My main quibble would be using an LED puck that may or may not be replaceable in 10 years.
