What are the disadvantages of passive solar energy?

Disadvantages of Passive Solar Energy

  • Limited Power Capabilities. Electrical power. Due to the nature of solar energy, it is only possible to generate a limited amount of power.
  • Upfront Costs. Cost.
  • Climate Dependent. Clouds block sunlight.
  • Appearance. Solar cells on roof.
