  • No harmful emissions are released when electricity is being produced by solar panels.
  • It also reduces the need for finite resources.

<em>Drawbacks-</em>

  • Solar Energy Storage Is Expensive
  • Uses a Lot of Space
  • Its Weather-Dependent, slthough solar energy can still be collected during cloudy and rainy days, the efficiency of the solar system drops.
  • Initial cost of purchasing a solar system is fairly high.
