If sunlight is free why is generating electrical energy from solar cells expensive?
The cost is in manufacturing the solar cells. It takes people, materials such as pure silicon and expensive machines to manufacture the solar cells. As researchers find cheaper materials and more efficient ways to make the cells, and the manufacturing volume goes up, solar cells will become cheaper.
How much does a solar cell cost?
The cost of a solar cell can vary depending on its efficiency, size, and quality. On average, a single solar cell can cost anywhere from $0.50 to $3.50. However, the overall cost of a solar panel system will depend on the number of cells needed and additional components.

How are solar cells of today superior to solar cells of the 1980s?
Solar cells of today are typically more efficient, producing more electricity from the same amount of sunlight. They are also more cost-effective due to advancements in manufacturing processes and materials. Additionally, modern solar cells are more durable and have a longer lifespan than those from the 1980s.

What is one disadvantage of solar cells?
One disadvantage of solar cells is that they can be expensive to install initially, although the cost has been decreasing over the years. Additionally, solar cell efficiency can be affected by external factors like weather conditions and shading.
How can you make a cheap Solar panel?
Solar panels can be made cheap by finding alternative, lower cost materials and producing them in large quantities. Solar panels are gradually coming own in price but still take many years to recover the initial costs.
How can electricity be derived from solar cells?
Solar cells have stored solar energy that is converted into electrical energy.
How many cells are in one solar panel?
One solar panel typically consists of multiple solar cells. The number of cells in a solar panel can vary depending on the size and type of panel. A standard residential solar panel may contain 60-72 individual solar cells.
What is cost of monocrystalline solar cells?
The cost of monocrystalline solar cells varies depending on the manufacturer, quality, and quantity purchased. On average, they can cost between $0.30 to $0.50 per watt for residential use and $0.20 to $0.30 per watt for utility-scale projects. Additionally, prices have been declining in recent years due to technological advancements and economies of scale.
What is the difference between solar furnace and solar cells?
A solar furnace is a device that uses concentrated solar power to produce high temperatures for industrial processes or research, while solar cells (or photovoltaic cells) are devices that convert sunlight directly into electricity. Solar furnaces are used for heat generation, while solar cells are used for electricity generation.
