Programmatically copy X number of panels within Form

I searched other SO articles but couldn't find a solution that works in my case.

My objective is to take a copy of panel1, which I have already created and formatted within Form1 and duplicate it on the Form1 n number of times.

I would like to space them out a given vertical distance as well. Below is the code I am using, it compiles without error however when I open my form it is not showing anything other than the original panel I manually created.

private void Form1_Load(object sender, EventArgs e)
{
    for (int i = 0; i < 5; i++)
    {
        int x = 100;
        this.Controls.Add(panel1);
        panel1.Location = new System.Drawing.Point(10, x);
        x += 200;
    }
}

EDIT: I have updated the code based on suggestions below but is still not working.

    private void Form1_Load(object sender, EventArgs e)
    {
        int y = 450;
        for (int i = 3; i < 6; i++)
        {
            Panel panel2 = new Panel();
            //Set Properties
            panel2.Controls.Add(this.button10);
            panel2.Controls.Add(this.dataGridView1);
            panel2.Location = new System.Drawing.Point(4, y);
            panel2.Margin = new System.Windows.Forms.Padding(4, 5, 4, 5);
            panel2.Name = "panel" + i;
            panel2.Size = new System.Drawing.Size(2754, 279);
            panel2.TabIndex = 0;
            y += 300;
            this.Controls.Add(panel2);
        }
    }

    int x = 100;
    for (int i = 0; i < 5; i++)
    {
        UserControl1 uc1 = new UserControl1();
        this.Controls.Add(uc1);
        uc1.Location = new System.Drawing.Point(10, x);
        x += 200;
    }

Firstly, you have to move the line int x = 100; out of the loop, or it will position every panel at the same coordinate.
Secondly, you can't add the same component multiple times, so I recommend creating a UserControl which you can then instantiate.
As a last note, I wanted to add that the variable x is used for the Y-Coordinate(I don't know whether that's intentional).

This is because you are not duplicating the panel control. You are just adding the same object multiple times and then setting the location on the same object.

Panel panelToAdd = new Panel();
panelToAdd.Location = new System.Drawing.Point(10, x);
//Set whatever properties you want
this.Controls.Add(panelToAdd);
