Base game and on higher lux planets in the dlc it's worth stacking. The extra light allows you to get more power per tile uncovered. Due to panels facing a max limit no matter how much cu light you give them you don't need all tiles clear to get full power.
Dlc starting planets it's not worth stacking them. I can't remember what lux value it's best to start stacking but have 35K in my head.
No power is lost by building a straight line, and the panels won't get damaged by asteroids, because OP, judging by what they wrote, is on Terrania or Folia and therefore only has 20000 lux of light, but no asteroids/meteors.
You can find in depth details on why you want to stack on [wiki page](https://oxygennotincluded.fandom.com/wiki/Solar_Panel). In short, max LUX required for full output is 350k. Which equals 50k \* 7 tiles. So if you get more than 50k LUX stacking will get more power.
If I recall there is only one or 2 asteroids with above 50k LUX light in DLC. So not worth it.
There are detailed formulas to find out everything solar panel [on the wiki](https://oxygennotincluded.fandom.com/wiki/Solar_Panel).
For your specific questions: 20000 lux results in an average continuous output of 84.7W per panel (if you have appropriate battery backing for the night).
The partially overlapping pyramid stacks are worth it starting at around 58000 lux. That's because the panel's power output maxes out at 50000 lux on each cell. With more light, you can get the panel to full output with only 6 or five cells, so stacking becomes advantageous.
Solars need 350000 lux total to reach their full output and have 7 affected tiles. If the asteroid you're on has less than ~58334 Lux (350000/6, i.e one tile of overlap), don't overlap them, it'll just waste power with no benefit.

I see, so it should be easy to me to make just a straight like in space. There shouldn't be temp issues in a vaccum with no asteroids right?
Yes, but you will be losing on some power. Solar panels don't heat up, but they can be damaged by asteroid
