Good evening, I don't know how to get sand to build solar panels or generate electricity at all.
I also can't get water.
Can anyone help me or give me some tips?

Hi! You need use offshore pumps to get sand, the rocks gives you basic ores so you can start

Thanks in advance for your reply.

I've already gotten that far, but how can I use the sand without electricity?

How do I get the sand from the pump into a kiln or a barrel?

With the basic materials you can make solar panels, are you playing with some overhaul mod?

The sand is only in the pump, so what happens next?

The early progression is:
Mine rocks > Melt ores > Make pumps, sifter and solar panels (Just iron and copper) > Make assembling machines 2 for barreling sand
You can also find cargo pod remnants in the sand for basic resources.
