What are the disadvantages of solar energy?

Disadvantages of Solar Energy

  • Cost. The initial cost of purchasing a solar system is fairly high.
  • Weather-Dependent. Although solar energy can still be collected during cloudy and rainy days, the efficiency of the solar system drops.
  • Solar Energy Storage Is Expensive.
  • Uses a Lot of Space.
  • Associated with Pollution.
