Answer :
The statement that solar energy is available only in the summer (Option B) is not a disadvantage of solar energy, as solar energy can be harnessed throughout the year.
The question asks which statement is not a disadvantage of the use of solar energy. Among the provided options:
- A. Solar panels are expensive: This is a known disadvantage, as the initial cost of solar panels can be high.
- B. Solar energy is available only in the summer: This statement is incorrect since solar energy can be harnessed year-round, although the efficiency can vary depending on the season and geographic location.
- C. Solar panels do not work very well: This is not accurate. Modern photovoltaic (PV) panels are effective and are continually improving in efficiency and cost-effectiveness.
- D. Solar energy produces greenhouse gases: The operation of solar panels does not produce greenhouse gases. However, the manufacturing process can generate some emissions, which is minimal compared to fossil fuels.
Therefore, the correct answer is B. Solar energy is available only in the summer, as it is not a disadvantage of solar energy use.
