RE: Celebrating a Milestone: My Solar PV System's First 1 MW Production

in Texaslast year

Even non-engineers would know the difference between:
'How many horsepowers does this car have?' (Pmax)
and:
'How much gas is left in the tank?' (E)

I came here because you replied to me somewhere else and gave me a lecture about what witnesses do... While I have myself have signed like 3000 blocks and missed like 400, being a backup witnesss before it was cool 😅

Anyways, I'll leave a follow, and will keep correcting on the W and Wh confusion that has taken over the world and drives me insane, frankly.
Once we start measuring Energy in [W] and surface in [football-fields] we are doomed as a civilization.

Greetings from Germany.

I'm sorry, I don't mean to come across as lecturing. I think it might have been about why we have 20% HBD interest. As far as I can tell, it's just a random number the witnesses chose.

As for mixing up energy and power, I understand. And I do not disagree. You are correct. I am an amateur radio operator and I have also undergone training for PV systems. Both require a knowledge of:

  • P = IV
  • P = V^2/R
  • P = I^2R
  • V = IR
  • R = V/I
  • I = V/R

All are variations of the interplay of power, voltage, resistance, and current.

But this blog post is about celebrating a small victory. For this, I have low technical standards.

It's funny. When I talk to my amateur radio friends, we constantly talk about the nerdy stuff: power, attenuation, SWR, ground planes, etc. But that switches off in mixed company. I guess this is a similar situation.

I didn't know until now, that you guys use (V) - In Germany it's (U)... [V] being the unit
I just memorized:

U = R * I (pronounced 'oory')
P = U * I (pronounced 'pooy')

And then I convert/insert until I get to whatever value I am looking for.

Anyways, congratz on the energy you harvested over time :)
