Even what s needed to burn coal takes energy.
Science to making solar panel.
Like all manufactured objects solar panels are manufactured.
To build your own solar panel you ll need to assemble the pieces connect the cells build a panel box wire the panels seal the box and then finally mount your completed solar panel.
Sunlight hits the solar panels and creates an electric field.
For my panel i had 3 strings of solar cells.
Science fair project idea solar cells are devices that can be used as a source of power when there is light shining on them but they stop producing energy when they are not in the light.
Mono crystalline silicon cells are more efficient than polycrystalline or amorphous solar cells.
I used tabbing wire with a soldering iron to connect the solar cells together.
Monocrystalline solar panels are produced from one large silicon block and are produced in silicon wafer formats.
The bus wire goes at the end of the strings to create one long string however curled up in a way like a snake.
All manufactured things that are used to make energy take energy to make.
Measure and record voltage resistance and current from each group.
The massive turbines that use the steam by boiling water by burning coal and turn that into electricity take energy to make.
The manufacturing process involves cutting individual wafers of silicon that can be affixed onto a solar panel.
Making such nanometer scale patterns from.
To connect those strings of solar cells i used what is called a bus wire.
The electricity generated flows to the edge of the panel and into a conductive wire.
One way to store the solar energy for later use is to use a solar cell to charge something called a capacitor.
