Congratulations, I like it when people make their own solar panels. But, they usually do not get the best results. The problem is usually that they mix solar cells with different curves of the characteristic current voltage. If the difference between the cells is very large, and that always is, your solar panel will work for a few years.
The other problem is that the front glass has to be iron free. If you do not have such a glass it is best to leave it unprotected because you will lose much of the important radiation if you use ordinary glasses.
My best wishes that it works perfectly ....
