Solar Generators cause crash

[stellanera98]

Issue description

Solar Generator and Advanced Solar Generator cause a crash when placed in biomes with a high temperature modifier due to the "peakMultiplier" becoming negative and being used in FloatingLong#multiply which is apparently not allowed to be negative.
I would expect the multiplier to cap out at 0 so this doesnt happen (and I've never heard of actual IRL solar panels taking power rather than generate)

Steps to reproduce

1 Find a biome (in my case I created my own with a temp mod of 5 out of curiosity) with a temperature above 4.1333 (relevant math: 1 - 0.3 * (0.8 - temp_mod))
2 Place Solar Generator or Advanced Solar Generator
3 Observe crash

Minecraft version

1.20.x or earlier (No longer being developed)

NeoForge version

47.4.0 (Forge)

Mekanism version

Older

Other relevant versions

Im aware that this is an older version but if you do run into this issue it would be difficult to resolve for the average player and its probably sufficiently solved by changing https://github.com/mekanism/Mekanism/blob/release/1.20.x/src/generators/java/mekanism/generators/common/tile/TileEntitySolarGenerator.java#L172 from return peakMultiplier; to return Math.min(0, peakMultiplier); but thats not for me to decide

If a (crash)log is relevant for this issue, link it here: (It's almost always relevant)

Main Issue:

I got this issue on 1.20.1 forge 47.4.20 too. I placed down an advanced solar generator, and it crashed my game. Unfortunately, the generator remains after crashes. This resulted in my 3 year world being unplayable unless I load that world without the mod. However, I have a huge heat generator room totaling 200 active, autonomous heat generators, meaning that if I were to load that world without the mod, I am risking losing a net worth of 8 weeks of progress.

To Replicate:

Go to any place in the world and place the advanced solar generator; after the crash occurs, try to load the world (this will likely result in a second crash either after some time or due to you breaking it). Be advised: the generator does not disappear even if you break it before the crash.

Possible work-around:
Install Neruina https://modrinth.com/mod/neruina
That should catch and kill the ticking entity (solar generator) before it crashes the world, and allow you to remove it safely.
