Agrivoltaics, saving farms

[Toddsterpatriot]

Just keep ignoring the waste heat from fossil fuels and you'll be ok.

Is the waste heat the reason solar is bad?

 

[ding]

Obviously. The panels are much warmer than the surface they replaced.

Tell that to the satellites, dummy.

I'm sorry I hate solar. I think you should install solar on your trailer.

 

[Toddsterpatriot]

Tell that to the satellites, dummy.

The satellites measured the temperature of the panels?

How hot do they get?

 

[ding]

The satellites measured 2C of localized cooling above 116 solar farms when the solar farms were generating electricity. How can solar panels absorb more heat than the surrounding lands and radiate less heat than the surrounding lands?

How can solar panels absorb more heat than the surrounding lands

By having a lower albedo.

Do solar panels cool the planet by causing "a net reduction of visible light photons warming the planet"?

You left out the other half of the question, EMH.

Is it because they magically destroy energy?

 

[ding]

Is it because they magically destroy energy?

It's because there is less upwards longwave radiation above the solar farms. Which shouldn't be the case if converting photons into electricity didn't produce a cooling effect that outweighed the increase in albedo.

Solar panels radiate less energy into space?

Less into space means more warming the planet.

You will never figure out why satellites measured 2C cooler temperatures over 116 solar farms until you account for the photons being converted into electricity.

Tell me, where did the energy go?

 

[ding]

Tell me, where did the energy go?

I have. Many times.

 

[Toddsterpatriot]

I have. Many times.

You told me it moved or you told me it was destroyed?

 

[ding]

You told me it moved or you told me it was destroyed?

I've told you enough times that you shouldn't still be getting it wrong.

 

[Toddsterpatriot]

Tell me again how many square miles of solar panels it takes to cool the planet.

That was brilliant!

It certainly seems to have you upset.

 

[Toddsterpatriot]

It certainly seems to have you upset.

Your errors don't upset me at all.

Neither did the errors of the "smart photon" moron.

If that were true you wouldn't still be chasing me around.

What percentage of solar radiation striking solar panels is in the visible light spectrum.
The answer is 40 to 44%.

What percentage of visible light striking solar panels is converted into electricity?
The answer is 15 to 20%.

So per square meter solar panels effectively reduce the 240 W/m² striking it by:
240 W/m² x 0.44 x 0.2 = 21.12 W/m²

What is the total land surface of the planet?
The answer is 149 million square kilometers or 1.49x10^14 m²

What is the solar radiation striking the total land surface of the planet?
The answer is 240 W/m² x 1.49x10^14 m² = 3.5760x10^16 W

What is the reduction needed to make the planet net cooling?
The answer is 0.7 W/m² x 1.49x10^14 m² = 1.0430x10^14 W

How many square meters of solar panels are needed to change the planet from net warming to net cooling?
The answer is 1.0430x10^14 W / 21.12 W/m² = 4.9384x10^12 m²

What percentage of the total land surface of the planet would need to be covered by solar panels to change the planet from net warming to net cooling?

The answer is 4.9384x10^12 m² / 1.49x10^14 m²= 0.0331 or 3.31% of the total land surface of the planet.

Nothing in these calculations about waste heat or fossil fuels.

What is the reduction needed to make the planet net cooling?
The answer is 0.7 W/m² x 1.49x10^14 m² = 1.0430x10^14 W

How many square meters of solar panels are needed to change the planet from net warming to net cooling?
The answer is 1.0430x10^14 W / 21.12 W/m² = 4.9384x10^12 m²

OMG!

You think solar panels somehow reducing the warming caused by solar radiation.

That's hilarious!

Moving that energy from a solar panel to my coffee maker can cool the planet.

DURR

The answer is 1.0430x10^14 W / 21.12 W/m² = 4.9384x10^12 m²

If you absorb 95% of the solar radiation hitting 4.9384x10^12 m², instead of absorbing 70%,
wouldn't you be warming the planet?
