BENEFITS

Solar energy offers many significant benefits, which include: 

• It's limitless and available worldwide.
• It does not pollute the water or air.
• It is essentially free. After the initial investment, the sun's energy energy is virtually free. 
• It has lots of flexibility because it can be used as is or help add energy to the grid. It can also be used in conjunction with other sources.
• It has numerous applications for supplying heat and power. 
• It's a perfect match for supplying high energy demands of the summer season.
• Solar systems provide customers more control since they utilize common materials and have minimal moving parts.

CHALLENGES

There are challenges to using solar energy, which include: 

• It's not constant. It varies depending on weather conditions, time of day, time of year and location.
• In a given location, it supplies only a small amount of energy. Lots of surface area is required to collect it.
• Setting up systems requires substantial initial monetary investment.
• A small amount of environmentally harmful toxic waste is produced while manufacturing photovoltaic cells.
• Solar power plants can harm desert ecosystems.
• PV cells are relatively expensive (although cheaper technologies are being developed).
