What are the 2 main disadvantages to solar energy?
The main disadvantages of solar power are:
- reduced power output in cloudy weather.
- no output at night.
- solar panels cannot store electricity.
- solar energy is a direct current and needs to be transformed for a.c. equipment.
- solar panels are inefficient, max 20%.
