Pros of using solar energy:
 • It is a renewable source of energy
 • Solar energy is free and abundant
 • Solar energy has low environmental impact
 • Solar energy can be used for both electricity generation and heating purposes

Cons of using solar energy:
 • Solar energy relies on the weather and can be unreliable at times
 • The initial costs of investing in solar panels and other equipment can be expensive
 • Not all areas have enough sunlight to support solar energy effectively
 • Solar energy produces direct current (DC) which is not always usable and must be converted to alternating current (AC)
