Solar energy is more expensive. The energy generated by solar PV panels is somewhat more expensive to produce than conventional sources of energy like fossil fuels. This is mostly due to the cost of manufacturing photovoltaic cells and the conversion efficiencies in the systems themselves, which can vary depending on the PV technology being used.
The primary role of a photovoltaic cell is to receive solar radiation as pure light and transform it into electrical energy in a conversion process called the photovoltaic effect.
