The sun can provide enough energy to meet our energy needs, and we are realizing the importance of harnessing this energy. A solar panel with dimensions of 1 m2 can generate 100 gigawatt hours of electricity per year.
A solar panel’s efficiency can vary due to humidity, pollution, cloud cover and other factors. Photo voltic (PV) cells have an operational life of 25 plus years. Maintenance costs are also relatively low.
