What are the disadvantages of a solar furnace?

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.
