Does anyone have information on which trial events are going to be at nationals this year?

According to chalker, they are:

For Div. B Solar Power, I found the device scoring formula very strange. As of now, the formula is
Final Score = [Part II raw score (based on 100 points)] - 5(Number of degrees increased in temperature - participant estimated change).

For the deduction part, it's entirely on estimation accuracy, not on efficiency. A very efficient device is actually in disadvantage. Consider 2 teams both have perfect Part II score as 100. Team 1 has the temperature raised by 20 degree, estimated 18. Then the final score is 100 - 5(20-18) = 90. Team 2 can simply put a mirror on top of the beaker, the temperature change would be 0, and they would estimate 0. Their final score is 100-5(0-0) = 100. So team 2 wins by having a very inefficient solar collector. This is clearly against the goal.

Yes I agree that is a rule that they need to look at and change because the rules are really vague and the building regulations are also vague...
Do you have any idea if we will be in the room as they test the solar panel such as if you have a box with a lens cover that needs to be adjusted as the light is turned on.

I don't know anything beyond the rules. But I know for most proctors, they will not touch participants' devices at all. They wouldn't want to be liable for breaking the devices. So participants must be there to set up testing.

Does anyone know whether if they will tell you what place you got in trial events even if you didn’t get a medal?

It should be on the scoresheet.

hippo9 is right, the places will still be on the scoresheet. As an example, here's last year's scoresheet: http://www.wright.edu/sont17 You'll notice after the main events, in gray it says "Roller Coaster (T/P)" and "Rotor Egg Drop (T/P), indicating that they are trial/pilot events.

Does anyone know where I can get some tests for solar power? Thanks.

Unlikely since it's a new event, but check the rules and maybe the soinc.org page for trial events to find out which state(s) ran it and maybe get a contact.

Trying to post this as widely as possible: we've revised the solar power rules to fix a few issues, primarily the scoring formula. Device specs haven't changed. The new rules are largely aligned with the Thermodynamics rules now. Check them out at: https://www.soinc.org/learn/trial-events

This is my last try, but does ANYONE have practice tests for solar power?

Is anyone willing to share how well their device for solar power is performing? Specifically, I just want to know how much the temperature increased.

Anyone know when and where impounds are for wifi lab? Did I miss something?

I don’t see anything on the website about impound. I think we just show up in the assigned time slot and check in the device when we get there.
