I'm new to this whole solar panel setup. I've managed to salvage a solar panel and I've been experimenting with a boost converter to get a stable output. I've tried setting it to 5.1V, but I noticed that the output voltage fluctuates based on the load. Ideally, I want the panel to output a constant 5.1V whether it's at its maximum output of around 8V or if the output drops below 5.1V. Any suggestions on what I should use to achieve this?

You might want to look into using a Buck-Boost converter for your project. This type of converter can handle situations where your input voltage is either above or below your desired output voltage, allowing you to stabilize the output at 5.1V no matter what input you get. It’s often easier to find these as PCB modules rather than building one from scratch.
Before you dive in, consider the size of your solar panel and the power requirements for your load. If your panel is rated at 4 watts and you need up to 2 amps for charging power banks, ensuring your converter can handle that current is crucial. Knowing these specifics can help you choose the right components.
