Disadvantages

• Solar electricity can sometimes be more expensive than electricity generated by other sources.
   

• Solar electricity is not available at night and may be less available due to weather conditions (solar panels generated reduced amounts of power in some types of inclement weather;) therefore, a storage or complementary power system is required.

• Solar cells produce DC which must be converted to AC (using a grid tie inverter) when used in currently existing distribution grids. This incurs an energy loss of 4-12%.
