Solar panels work well only in sunny areas.

The plants that use photosynthesis would die because the plants would not create food. They would die of hunger. Without another source of food, most of the animals would likewise die off. Most life would die anyway because the oxygen released by the plants would no longer enter the atmosphere to be used in respiration. Photosynthesis is an irreplaceable part of the carbon cycle, on which the vast majority of life on Earth depends.
It is an alternative energy source.
The light reactions provide the energy carriers used in the Calvin cycle
Less sunlight is being used by photosystem II
The water cycle gets disturbed by human activities. Pollution also hinders the water cycle.

Burning fossil fuels can emit carbon dioxide, which is a gas that helps keep the Sun's rays from burning you to a crisp or outer space from freezing the entire Earth solid every night. There are other such gases, like methane and water in gas form (water vapor). The many independent (not government-sponsored) published scientific studies that have been done show no relationship with any kind of climate change.
