General help that does not fall into a more specific category

Hello everyone,

I try to determinate the power received from the sun by a satellite.
I did every tutorials and try to find a way but I did'nt...!
That is why I posted this question here

Is there a way to define a solar panel area for the satellite ?

My aim is to determine the minimum area of panels to obtain a desired power (let say I want to know the area to obtain 10W of power, for one orbit at an given altitude).

If anyone could help me, I would really be grateful.
I wish you a very nice day.

Olivier.

Hi Olivier,

Unfortunately GMAT cannot not calculate power obtained from a solar panel.

GMAT is used for trajectory modeling only; for power calculations, you'll need another tool for that purpose.

Once you figure out a solar panel area, you can put that information into GMAT in the form of `Spacecraft.DragArea` and `Spacecraft.SRPArea` so that it can be used for drag and SRP modeling.

I could read in the HELP that we cannot determine the eclipse and sunlight periods (for a satellite) yet, so I won't ask you

Have a nice day !

That's something we're actively working on. Expect news this fall.

you can use crystalline silicon solar panel for the satellite.I think this panel have the ability to take maximum power from the sun through the process of chained bond reaction with silicone atoms and the gas obtained from the sun.
