Enjoy the free energy. I think some people are surprised that solar panels work when it is cloudy. I think small DIY systems can pay back fairly quickly. Ours is fairly big and I wanted it done professionally as I was not going to climb on the roof and wire it all up.
Until this year, we had amazing governmental programs for homeowners to install solar panels and batteries, but not this year. Especially then, when free money is coming from the state, you have to go to a professional setup. I've also been surprised by how easy it is these days to build a scalable DIY setup. My luck is that I have a garden that faces south, and I've placed the panel on the ground.
