Question

why are solar panels built up instead of using a solar cell​

Answer 1

Answer:

Because they are more powerful than solar cells and are eco friendly.

Answer 2

Answer:

Solar cells and solar panels are both integral, and closely related, parts of a solar energy system. When reading about solar energy systems, it may seem as if these titles are almost interchangeable. Writers refer to them both when discussing energy production and output, and often do so without explanation of how these parts work. However, each plays a distinct role. Solar cells contain all the parts necessary to convert sunlight to electricity. Solar panels combine and direct all of that energy .

Explanation:

Solar panels are a great way to offset energy costs, reduce the environmental impact of your home and provide a host of other benefits, such as supporting local businesses and contributing to energy independence.

so solar panels are built up!!!!
