Making a DIY Solar Panel/Finding its maximum power point/Solar panel experiments

Here’s a story of me building a DIY solar panel. For this I’ve used polycrystalline solar cells of 0.5V and 3.6W each. Hopefully after soldering everything together in series I should get an 8V and approximately 58W panel. Let’s see how it will turn out and find its maximum power point.
I’ll also tell you about the assembly process, and about the problems that I've encountered while building this solar panel, and how to avoid them.
Was this project worth it? Absolutely! See for yourself!
