The main disadvantage of solar energy is that it only works when the sun is shining.
This can be overcome by storing the daytime energy in some way so it can be used during the night. This can be done by charging batteries, by pumping water uphill, or by heating something that will hold the heat all night. Molten salts can be heated up to 600°C at the top of Concentrated Solar Towers. This allows electricity generation 24 hours a day.
The disadvantages of heat are that if there is no solar energy, then there is no heat.
disadvantages of solar energy opposed to fossil fuel?
What are some disadvantages or advantages in chemical energy?
it is environment friendly. But, the solar cells need service and repair time to time
Solar energy is not available when the day is cloudy.Wind energy is not available when wind is not blowing.
Disadvantages: May not produce enough energy to run appliances, solar radiation
solar energy cannot be collected at night or cloudy days, and when they turn the solar {sunlight} to make energy it releases a harmful chemical.
Some of the disadvantages of solar energy are the means of collection and the necessity of the sun. Solar panels can be very fragile and easily broken and they do not operate at peak efficiency unless aligned properly.
The disadvantage is that the amount of energy is small. Moreover if it's not sunny you won't get the energy.

Some disadvantages of solar energy include its intermittent nature (dependent on weather conditions), the need for large surface areas to generate significant power, and the initial high cost of installation. Additionally, solar energy production can be impacted by geographic location and the efficiency of solar panels.
Some disadvantages of using solar energy include the high initial cost of installing solar panels, the intermittent nature of sunlight depending on weather conditions, and the need for large amounts of space for solar panel arrays in order to generate significant amounts of electricity.
