Questions and Answers

In what way can industrial processes maximize the dispatchability of solar energy?

  • By modifying processes to align with solar energy availability and using small storage solutions. (correct)
  • By switching entirely to fossil fuel energy sources during off-sunshine hours.
  • By using solar energy only during peak sunshine hours, ignoring off-peak times.
  • By relying solely on large-scale energy storage solutions.

Which factors are most important when identifying a suitable solar thermal energy system for a specific industrial application?

  • The color of paint used on the industrial building and the brand of solar panels available.
  • The current price of fossil fuels, the distance to the nearest city, and the business owner's political affiliation.
  • Available solar resources, application temperature requirements, and schedule of energy usage. (correct)
  • The building material of the factory, air conditioning costs and personal preference of solar panel brand.

What critical aspect should be analyzed when assessing the economic viability of implementing a solar thermal energy system in an industrial setting?

  • The aesthetic appeal of solar panels and the current popularity of renewable energy.
  • The potential for increased employee morale due to the use of green energy.
  • The reduction in fuel costs compared to the higher upfront capital costs of solar collectors. (correct)
  • The ease of obtaining government subsidies for renewable energy projects.
