Question

Why is it very expensive to use solar cells?

Answer 1

Solar cell

1. A solar cell, also known as a photovoltaic cell, is a device that directly transforms light energy into electrical energy through the photovoltaic effect.

It is very expensive to use solar cells because

1. Nature has a limited supply of the special grade silicon necessary to manufacture solar cells. As a result, it is very expensive.
2. Silver, which is used to link the individual cells in a solar cell panel, is also expensive.
3. The cost of storing power in storage batteries is high.
