Solar furnaces can be expensive to build and maintain, requiring significant upfront investment and specialized materials. They are highly dependent on weather conditions, making their efficiency variable and limiting their effectiveness in cloudy or rainy climates. Additionally, solar furnaces can have a large physical footprint, necessitating substantial land use, which may not be feasible in urban areas. Lastly, they often require a complex tracking system to maximize sunlight exposure, increasing operational complexity.
The first solar furnace was created by French physicist Auguste Mouchot in the 1860s. Mouchot developed a solar concentrator that used mirrors to focus sunlight onto a receiver, generating steam for mechanical work. His work laid the foundation for solar thermal technologies, although it was not widely adopted at the time.
Some of the disadvantages of solar energy are the means of collection and the necessity of the sun. Solar panels can be very fragile and easily broken and they do not operate at peak efficiency unless aligned properly.
Disadvantages: May not produce enough energy to run appliances, solar radiation
Some disadvantages of using solar energy include the high initial cost of installing solar panels, the intermittent nature of sunlight depending on weather conditions, and the need for large amounts of space for solar panel arrays in order to generate significant amounts of electricity.
A solar furnace can reach temperatures of over 3,000 degrees Fahrenheit (1,650 degrees Celsius) by concentrating sunlight using mirrors or lenses. At these high temperatures, materials can be melted, vaporized, or used for industrial processes like metal smelting.

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.
The Sun. "Solar" means that it is somehow related to the Sun.
Provided you are nowhere near the focal point of the furnace then they are perfectly safe.

The disadvantages of heat are that if there is no solar energy, then there is no heat.
it is environment friendly. But, the solar cells need service and repair time to time
The heliostat, or array of mirrors, moves so as to keep the sun's rays focussed on the top of the solar tower.
