i hve more than 5000 solar sats at my planet and the energy says ut is 7500/7500 and i have loads of mines working too?

did you also make sure how cold your planet is? because the colder the planet the farther away it is from the sun, so you will even if you have a lot sats they might not produce as much energy.

never mind i found out what was wrong on the resorces tab the solar sats were set to 0 percent production
