The technology does not release any carbon, methane or other harmful gases into the atmosphere and does not require large-scale mining or drilling operations. The use of solar panel produces no pollution, no noise and no hazardous substances. The solar power industry results in the creation of thousands of jobs.

This creates jobs. Conclusion My conclusion is that although the cost of installing solar panels may be higher than and/or close to the yearly cost for electricity, solar power will save money in the long run and is more beneficial to the environment as it does not emit harmful substances.
