Technical FAQs 4

What are the disadvantages of solar power?

A notable disadvantage of solar power is its heavy reliance on weather conditions. Solar panels generate electricity by converting sunlight, meaning their efficiency drops significantly during cloudy days, rain, or snow. For instance, output can decrease by 10–25% in overcast conditions, according to the National Renewable Energy Laboratory.

What are the challenges of solar energy?

The challenge of solar energy is not only the initial installation cost but includes environmental pollution linked to manufacturing, heavy dependence on weather conditions, lower efficiency of cells and limited energy storage capabilities.

Are solar panels bad for the environment?

Related: Disadvantages of renewable energy While solar energy is a clean and renewable source of power, certain stages in the life cycle of solar panels can have adverse environmental impacts, particularly during manufacturing and decommissioning.

What are the pros and cons of solar energy?

Here’s a clear comparison of the main pros and cons of solar energy: Solar energy is one of the most abundant and renewable energy sources available. It converts sunlight into usable electricity or heat, helping reduce dependence on fossil fuels, lower energy bills, and support long-term environmental sustainability.
