Solar energy is energy from the Sun and is a vital resource to plant and human life on the Earth's surface. Plants need solar energy in photosynthetic processes leading to plant growth. Human beings benefit indirectly through consumption of the plants. More so, solar energy determines climate changes which in turn affect natural processes on and under the Earth's surface. The solar energy can be utilized directly through drying of foodstuffs and heating of water for home and commercial consumption. Indirect use of this energy resource is evident in generation of electricity using photovoltaic systems.
